Nitrogen Fixation and How We Can Use It

Nitrogen is an essential nutrient for all living things. Where does that nitrogen come from? It comes from the atmosphere, which is composed of 78% nitrogen; but that gas is quite inert, meaning it can’t combine with other elements until it is broken into a simpler form. This process takes a lot of energy to “fix” the nitrogen. There are three processes that can fix nitrogen: atmospheric, Haber Process and biological.

Atmospheric fixation occurs when the high temperature of lightning splits the nitrogen gas so it bonds with oxygen and moisture in the air to form nitrates that fall to the earth with rain. This natural fertilization benefits plants. Some people have asked, Is it my imagination that my grass looks greener after a thunderstorm? Maybe not; it could be due to the nitrogen as much as to the water.[Read More]

What the GMO?

GMO has become a dirty word and a symbol for Monsanto’s corporate control over our health. Genetically modified organisms (GMOs) are the result of slamming DNA (genetic material) from one organism with the DNA of another, yielding altered characteristics. The bizarre results are discarded and the profitable ones, like being unaffected by the herbicide Roundup, are reproduced. Current approved GMO crops include Roundup Ready corn, soybeans, canola and this year, sweet corn. The advantage with these crops is that a farmer can have easy perfect weed control, by spraying the whole field with the herbicide Roundup, killing the weeds but not the crop.[Read More]

Goldflame Spirea (Spiraea bumalda ‘Goldflame’)

Here’s a shrub that won’t grow over the living room windows, spread half-way across the driveway or send suckers up in the perennial border. It stays a compact 2’-3’ high and a little wider. It’s name comes from its spring leaf coloration which begins a russet or bronze-red mixed with yellow, changing to yellow-green and then green. The flowers are pinkish and bloom for a long time. Then again in the fall the spring leaf colors return to a golden copper-orange. This variety is very heat tolerant and has been successful in my xeriscape garden for 7-8 years. Occasional winter dieback has been slight and easily sheared off with hedge clippers. I also use the hedge clippers to remove the spent flowers after blooming.[Read More]

Soil: The New Frontier

Do any of you have dirt under your fingernails? Good. You and all gardeners have direct experience with soil. Those of you who don’t get your hands in the dirt probably will, because soil and soil building is the next frontier. Why do I say that?

Because until recently our understanding of soil and our approach to soil fertility was steeped in ignorance and misunderstanding. We’ve been in the Dark Ages.

Does anybody know the meaning of a new paradigm? It does not mean coming up with a new idea; it means coming up with a new perspective, a new ground from which to begin our thinking. We are entering a new paradigm in relation to the earth.[Read More]

A Bad Year for Fire Blight

This is a bad year for fireblight which is a bacterial disease which affects mostly apple, pear, crabapple, hawthorn and Mt. Ash. It is spread in the presence of moisture and enters the trees through wounds and open blossoms. Colorado is the worst state in the US for fireblight.

Because of our moist spring and extra wounding caused by hail, there is a lot of infection. Symptoms include black, hooked twig ends, brown or blackened leaves, dried up fruits and sunken cankers that can be a dull orange or black. Fireblight is a difficult disease to manage because there is no cure. Spraying chemicals is not recommended by CSU because they are not very effective, timing is critical and spraying must be repeated.[Read More]

Cold-Hardy Climbers

At the end of last season I wrote about how to succeed with climbing roses in Colorado. Besides winter watering and careful siting out of the worst wind, the most important factor is the choice of very cold hardy roses that are grown on their own roots. The books may say we are zone 5 but when the temperature drops from 50 at noon to 5 at two a.m., we better hope our rose is zone 4 or even zone 3 hardy. With climbers this is even more true because if the canes die back to two feet the rose may still bloom but it won’t function as a climber that year. Here are a few of the toughest and most cold-hardy climbing roses for Colorado.  [Read More]

Philadelphus – Mockorange

Nearly everybody has met the memorable fragrance of mockorange, said to imitate the smell of orange blossoms. There are over a hundred species of Philadelphus, and of these, about 40 are native to North America. Many of the yards of Boulder County and Denver have at least one specimen. What is so good about this shrub? Dirr says, “In flower they are attractive to some, but the rest of the year are real eyesores.” Wyman said their fall color is not vivid, their fruits are not ornamental, no winter interest, but they are “cultivated 50 weeks of the year in order that their flowers may be appreciated for two weeks.” However I happen to love mockorange, and one of the 2001 Plant Select shrubs is ‘Cheyene’ Mockorange. So let’s look into the good qualities.[Read More]

Geraniums for Sun or Dry Shade

Hardy Geraniums are in general very serviceable and these four have been very useful and successful for me. They are tolerant of diverse and adverse conditions and are especially useful in dreaded dry shade.[Read More]

Fireblight: How to recognize it and deal with it (1997)

One of the most damaging and most perplexing diseases of the Front Range is fireblight. It is a bacterial disease affecting apples, crabapples, pears, Mt. Ashes, pyracanthas, quinces, hawthorns and occasionally cotoneasters. Fireblight does not affect cherries, plums, peaches or shade trees.

When the bacterium with the lovely name Erwinia amylovora enters the trees through an opening such as a wound, a pruning cut, the open blossom or leaf pores, the tissues quickly die causing blossoms and leaves and young twigs to suddenly wilt and turn black as if scorched by fire (hence the name “fireblight”). As the bacteria spread through the tissues, secondary infection continues through the season and bark areas die, become sunken and turn black or reddish-orange. These areas are called “cankers”. Sometimes large numbers of leaves turn black but the infection stays confined to small twigs; sometimes entire large branches die; occasionally the entire tree will die.[Read More]

Groundcovers Project in its 18th Year

In 1993 I sent a survey to 29 local horticulturists to get their suggestions on the best groundcovers for a demonstration project we were planning at Harlequin’s Gardens. I asked them to list 5-10 groundcovers that could be used to replace bluegrass in low traffic areas, that would need a quarter to a half the water of bluegrass, have few pests and diseases, would grow densely to limit weeds, would look good in most seasons and would not be invasive in gardens. The survey was typed on a typewriter and most of the replies were hand-written. People did drive cars back then. But that was a long time ago and I had a lot to learn.[Read More]

Serviceberry

Saskatoon Serviceberry (Amelanchier alnifolia)

A winter-hardy (zone 4) native shrub of the Great Plains and Rocky Mountains. It has beautiful coarsely toothed leaves that are attractive even in the dry summer. The flowers are white and apple-like, fragrant and appear very early in the spring. Delicious blueberry-like fruit follow in midsummer. Birds are very fond of them and the American Indians used to mix these serviceberries with fat and buffalo meat to make their winter staple, pemmican. The Canadians have been working to develop this plant for fruit production.[Read More]

Hardy Geraniums

Hardy Geraniums are one of most versatile an adaptable perennials for our area. Available in many colors and habits, they can be useful in sun and shade, moist and dry, as a single specimen, as companion plants and as ground covers. These are not to be confused with the Pelargoniums which are the house plant, container and bedding plant “geraniums” which are not hardy outdoor plants in Colorado. The name “geranium” is derived from a Greek word meaning little crane, hens the common name “cranesbill” which refers to the appearance of the seed heads. The majority of the species of geraniums are native to the northern and mountain regions of Eurasia and North and South America although some are found in South Africa, India, Indonesia etc. Most grow in grasslands, meadows, roadsides and open woodlands. Therefore the natural habitat for most hardy geraniums seems to be sunny and moist or part-shade and moist or dry.[Read More]

Japanese Beetle is Here

Japanese Beetle is one of the most damaging insect pests in the Eastern and Midwestern US, but until recently, Coloradans were spared that challenge. It entered the US in 1916, but took until 2003 before a population was established in Colorado. This first infestation was in the Palisade area on the Western Slope. Even though eradication efforts were mostly successful there, established populations have been found since 2005 in Pueblo, southern Denver, Englewood, at DU and at Denver Botanic Gardens. Populations are being seen now in Boulder and Jefferson County.[Read More]

Heat-Tolerant Plants

Most of our native plains plants and shrubs including:

Sumacs
Penstemons
Rabbitbrushes
Desert Four O’Clock
Saltbrush
Heterotheca
Artemisias (Sages)
Thelesperma
Gambel Oak
Sulfur Flower (Eriogonums)[Read More]

Small Shrubs that Fit In

There has been a lot of interest at our nursery, and in current plant-breeding programs for smaller shrubs. Most of the old-time favorite shrubs are very large. Most lilacs, viburnums, honeysuckles, forsythias, privets, elderberries, serviceberries, butterfly bushes and hibiscus are 6’-12’ high and often as wide. These are great to provide screening and big masses of color along fences or the back of the border.[Read More]

Managing Grasshoppers without Poisons

Nolo Bait is not a poison. It is a parasite that only affects grasshoppers and Mormon Crickets. It will not harm people, pets, wildlife or beneficial insects. It is most effective on small grasshoppers. In 3-4 weeks up to 50% of the grasshopper population will die. In addition, their eggs will be infected for the following season, and because grasshoppers are cannibalistic, they spread the disease. Put out shallow trays of the bran bait in small quantities. Wind, rain and contact with soil organisms can reduce bait available to grasshoppers.

Ducks, chickens, turkeys and guinea fowl can significantly reduce grasshopper populations. They must be fenced and put inside a safe structure every night to protect them from predators. They will also eat some plants, like vegetables.[Read More]

Managing Weeds Organically

 

This is the perfect time to apply Corn Gluten to prevent new weeds.

There are simple steps you can take now to keep your garden organically weed-free all season long

Smoketree

Cotinus, known as Smoketree, is a genus of woody plants appreciated for their “smoky” flower plumes and for their leaf color, especially in autumn. Michael Dirr in his famous Manual of Woody Landscape Plants says “…it may be the best of all American shrub/trees for intensity of color.” Two species and many selections and hybrids offer leaf colors ranging from rich blue-green, maroon red, purple-red and yellow-gold; and the fall colors are even more vibrant. With the current passion for new plants, it is curious that Smoketree is not seen more often in our western landscapes.[Read More]

Lavandula – The Lavenders

Lavenders are great xeriscape perennials for Colorado, which bloom in the heat and dry of July and August. They are native to the rocky hillsides of the Mediterranean region. Here as well, they like good drainage, full sun, our alkaline soil and dry, loamy humus. Lavenders are aromatic herbs with gray foliage, the leaves as well as the flowers being strongly fragrant.[Read More]

Roses that Survive and Thrive in Colorado

After last November’s 77 degree cold plunge to 13 degrees below zero, most roses suffered die-back, some died to the ground and some died completely. But there were roses that had only minimal damage and some that will bounce back with a good show of vigorous growth and generous flowering this year. Here are some observations and conclusions about growing sustainable roses in Colorado.

Roses are cane shrubs, similar to blackberries and raspberries. Their wood has a pithy center and is not as hard or as strong as a lilac. Consequently roses are more vulnerable to insects, diseases, desiccation and cold, but another consequence is that they can grow and regrow much faster than woody shrubs like lilac and viburnum.[Read More]

Lawn Alternatives and Groundcovers

In our American communities, one of the responsibilities of home-ownership is to keep the ground covered. Bare earth, like weeds, indicates lack of care. So then, how do we cover the ground? The cheapest, fastest, and easiest way is to roll out bluegrass sod. “Instant” landscapes can be accomplished with a supervised construction crew that knows little about plants. And as long as water was plentiful, bluegrass was the unquestioned solution.[Read More]

Sungari Redbead Cotoneaster

The 2017 Plant Select shrub introduction is a woody plant with a tongue-twister of a name, a long history of survival at the old Cheyenne Horticultural Station, and has a heart-warming story of two great local plantsmen who brought it out of obscurity into Colorado gardens.

Cotoneaster racemiflora soongorica or Sungari Redbead Cotoneaster is a very tough and beautiful shrub, having survived over 40 years of neglect at the closed and unwatered Cheyenne High Plains Horticultural Research Station. It grows 6′-8′ high and wide with arching branches. The dark green leaves that are gray-white underneath, are attractive in themselves, and the flattened clusters of white, Hawthorn-like flowers are some of the showiest of all cotoneasters. They attract bees and other pollinators. Following the flowers are showy red fruits, a quarter of an inch or more in diameter. These berries are not messy and are popular with garden birds. They cluster along the thin branches, appearing as ropes of beads — hence the common name.[Read More]

Pest Management for Bees

Overview: The Good News: 100,000 insect species; only 200 pests. We do not need neonics or any toxic pesticide to grow plants well. The solution is human attention, biodiversity, nutrient-dense soils, application of nontoxic management, and tolerance.

The Bad News: Most people and most nurseries don’t know the good news. They believe the chemical companies that we need to fear and attack insects and fungi as enemies.

More Good News: The concern of ordinary citizens who call nurseries and businesses and ask them if they are using systemic neonic poisons in their plants, is having a powerful effect. These companies now know we care and will buy plants that are neonic-free if we can. This could get them to change.[Read More]

Pruning Article for Boulder Home and Garden

For many people, pruning is the maintenance job they most fear and dread. And it is good to be wary, because a tree that is badly pruned can dominate a landscape with its ugliness for years, can be more prone to breakage and disease, and can have a much shorter life.

Tree and shrub pruning have four basic aspects: the practical or aesthetic interests of the owners, the biology of how trees “heal”, the physics of what makes a branch strong or weak, and the art of how to create beautiful forms.[Read More]

Pyrethrum Insecticides: Are they Safe?

Pyrethrum is one of the best known botanical insecticides, effective against a wide variety of insect pests and generally considered safe to use. Is it really safe? To answer any question about pyrethrum it must first be explained that what is referred to as “pyrethrum” can be many different products. There is pyrethrum, the raw flowers; pyrethrins,the extracts from the flowers; and pyrethroids, synthetic pyrethrum. In addition many other insecticides and enhancers are often added to formulations which are called “pyrethrum”.[Read More]

Bees, Neonics and the Organic Way

Pesticides were never a good idea. They were designed to make money from petroleum, not to benefit the public good. Pesticides, fungicides and herbicides are poisons that were developed to kill life. Not only has this approach poisoned our earth and ourselves, it has failed to control Nature. Our soils are less productive, and weeds and pests have adapted by becoming resistant. Stronger poisons are not the answer.

In the last 20 years, the new “nicotine” pesticides (neonicotinoids) have become the industry standards because they are less toxic to people and animals than the old organophophate pesticides, and that is good. But the neonicotinoids (neonics) are even more toxic to insects; they last 3 months to 5 years; all parts of the plants are poison, and the poison goes into our water.[Read More]

Boulder Dushanbe Teahouse Rose Garden

Boulder Valley Rose Society
Hardy Roses Demonstration Garden
1770 13th St. Boulder, Colorado

This garden, planted in 1998, is both the Hardy Rose Demonstration Garden of the Boulder Valley Rose Society and an environment that delights the senses and calms the spirit, such as you might find at a teahouse in Tajikistan.

Designed by Eve Reshetnik-Brawner and Mikl Brawner, the garden includes 43 varieties of roses of many types, including Old Garden roses, Species roses, Canadian, Modern Shrub and David Austin’s English roses. These roses were chosen for their Old World Character, cold hardiness and disease-resistance. In addition, these roses are not grafted, but grown on their “own roots” which makes them tougher and longer-lived. These qualities have allowed the Boulder Valley Rose Society to maintain this rose garden without the use of chemical fertilizers, fungicides and pesticides. These roses are examples of how successful roses can be in Colorado.[Read More]

We Have Soil Products for You!

It’s time to prepare your soil!

Thank you to all those who helped us with a successful opening day, last Friday!  And a big thanks to those who braved the elements later in the weekend to stop by!  Throughout the month of March we’ll be open four days a week from 9 AM to 5 PM on Thursdays, Fridays, Saturdays and Sundays.

March is a great time to focus on soil enrichment and we’re stocked with great products that will help you prepare for the season ahead.  You’ll recognize many products which we’ve stocked for years and we’re also trying out some new and exciting items.  As always, we welcome your feedback on them all!  

Classes

This weekend we’re featuring three great classes.  We start on Saturday, March 9 at 10 AM, with two of our favorite Permaculturists, Tara Rae Kent and Daniela Escudero sharing some important principles to create more resilient and regenerative systems in our own gardens in their “Intro to Permaculture” class.  Free Admission! 

Stick around on March 9 because at 1:00 we have a one-time-only presentation on “Cover Crops: Why, How and Which” with Clark Harshbarger.  Clark who is employed with the USDA-NRCS as a soil scientist and recently as director of Regenerative Farming at MAD Agriculture, will soon be moving to eastern US.  For this special presentation we are renting a larger space next door at the Boulder Circus Center.  This special class is only $20.  (See the list of cover crop seeds that we’re offering, below.)

Finally on Sunday, at 1:00 pm, Mikl with share how to address “Fireblight” issues, which were a hardship for many gardeners last year.  See below for more details and call 303-939-9403 to reserve your seat!


MARCH CLASS LIST

Call 303-939-9403 to reserve your seat!

Our weekends are loaded with great classes you won’t want to miss! Our customers tell us that our classes have given them tremendous value, with practical and current information from local experts who have spent years honing their skills in Colorado and will help guide you to success. We are charging $15 (unless otherwise stated) for our classes to support our speakers and Harlequin’s educational direction. It is best to pre-register for these classes both in case they fill up, or too few people register and we have to cancel. Pre-payment assures your place in the class. You can register at the nursery, by mail, or by calling 303-939-9403. We are unable to take class registration by email at this time.  Most of our classes run from one-and-a-half to two hours in length, and sometimes longer for hands-on classes, or if there are a large number of questions.  See the complete March Class listing below, or on our website.  

Sat, Mar 9 at 10 AM
Introduction to Permaculture with Tara Rae Kent & Daniela Escudero  

Permaculture is a design science that is informed by cycles and patterns in nature. This helps us create more resilient and regenerative systems, whether those systems are gardens, farms, businesses, or events. We will explore the ethics that guide a permaculture design and the principles that help a design take form, as well as real life examples and projects that are a part of our lives. The class will include: 1) an introduction and exploration of the Permaculture Ethics and Principles, 2) real life, active and diverse examples of permaculture designs, and 3) a tour of Harlequin’s Garden’s Permaculture Design.  Free admission!

Cover Crops for Gardeners: Why, How & Which with Clark Harshbarger  

In the current soil revolution, we are learning how to nurture and care for our soils and the soil life that is the true source of soil fertility. Cover crops are becoming recognized as one of the keys to soil fertility and soil health. When our annual crops die in the fall, if we do not replace those crops with living plants, then the microbes that depend on the nutrients “leaked” into the soil from plant roots, will die or decrease. Besides that, cover crops are a method to use photosynthesis to grow organic matter and nutrients including nitrogen to add to the soil, so we have to buy fewer amendments. In addition, many cover crops support beneficial insects which help control pest insects, and they reduce erosion.
 
But which cover crops do well in Colorado and when do we plant them and when should we cut them, and how do we prevent them from becoming weeds or competitors? And how best to combine them?  Harlequin’s Gardens has been looking for someone to teach us these things, who really knows how to do it in our local conditions. And this year we found the right person. So this is a great opportunity that will not be available next year, because Clark Harshbarger will be moving to eastern US.  For the last two decades, Clark was employed with the USDA-NRCS as a soil scientist and recently as director of Regenerative Farming at MAD Agriculture.
 
We have rented a bigger space than our classroom, but people will have to register ahead of time to make sure they get a seat. Clark’s class will be held at the Boulder Circus Center, next door to Harlequin’s Gardens, south in the big metal building in the Trixie Room.  Register by phone at 303-939-9403. This will be a 2 hour class and we will be charging only $20.

Sat, Mar 16 at 1 PM
Mason Beekeeping with Tom Theobald  

The importance of our native ‘solitary’ bee species to the pollination of our crops, flowers, and native plants is receiving increased attention. For over 30 years, Tom Theobald of Niwot Honey Farm has been propagating one of the most ‘useful’ species, Mason Bees (Blue Orchard Bees), and will teach how to attract and care for these gentle native pollinators. Mason Bees are not a replacement for honeybees, but they are excellent pollinators of the early fruits – cherries, apples, etc.  They stay close to home, don’t sting, don’t require the year-round commitment of a colony of honeybees and provide a great way to introduce children to the world of pollinators. Harlequin’s Gardens will have filled straws (containing male and female adult bees in hibernation) for sale for $12 a straw. 
IMPORTANT: You must RESERVE your Mason Bee straws IN ADVANCE by calling Harlequin’s Gardens at 303-939-9403. Pre-payment of mason bee straws is required. Class cost: $15.  (Note: this class is a repeat of Tom’s March 2 class.) 
 

Sun, Mar 17 at 1 PM

Class cost: $20.   (Photo credit, left: ColdHardCactus.com) 
 


Products for Building and Supporting Healthy Soils

Harlequin’s Gardens has been studying soil health for many years now, because soil health is needed for plant health, for plant resistance to pests and diseases and for nutritional value of plants. We believe that a strong Soil Life with all the beneficial fungi, bacteria, earthworm etc. is the goal to digest the nutrients in the soil and make them into plant-available forms.

Our soils also are deficient in organic matter and available nutrients. Colorado soils do have nutrients, but many are not in a form that’s available to plants. So, Harlequin’s has sourced most of our soil-building products from businesses as local as possible, almost all from Colorado. Local products use our local wastes (like landscape wastes, beer wastes, food wastes, beetle-kill pine, mushroom waste, dairy cow manure, chicken manure). This supports local businesses to recycle and because trucking distances are greatly reduced, we are cutting down on carbon emissions. Putting these organic wastes into the soil also sequesters carbon. And because carbon is one of Life’s main building blocks, these products help build fertility.

This year we have many returning products and some new products that we’d like to tell you about.

Humate

This is a mined carbon concentrate that multiplies microorganisms and has the effect of making nutrients in the soil available. We have been using this for years in our potting mixes. 

Corn Gluten

A non-toxic, weed-and-feed with 9% nitrogen. It inhibits seed germination, but is harmless to plants with root systems, people, worms, and microorganisms. The effect can last up to 6 months and is especially useful in lawns. Apply in September/October, and again in late February/March to prevent the majority of existing weed seeds from germinating.


Alpha One

100% organic fertilizer for vegetables and ornamentals. Contains: 7% Nitrogen, 2% Phosphorus, 2% Potash, 1% Iron, 1% Sulphur, with a pH of 6.2.  Formulated in Loveland for Colorado Soils. 

Richlawn 5-3-2 Fertilizer 

A 100% organic product comprised of dehydrated poultry waste.  It is listed by OMRI for organic use and is ideal for lawns, trees, shrubs, annuals, perennials, vegetables and roses.  One bag covers 2,000 sq. ft. of turf.

EcoGro Compost

A Class 1 Compost made from leaves, grass, chipped branches, and beer wastes. It has a healthy population of microorganisms and diverse nutrients.  It is very stable and will not burn or steal nitrogen.  It is fine textured, low in salts with some woody particles.  The pH is 8.3; the NPK 1-1-1.

Eko Compost

Made from forest and recycled wood products composted with poultry manure. Use Eko Compost in vegetable and flower gardens, on lawns, trees, shrubs. to Improve soil’s physical, chemical, and biological health.

Having trouble with insects in your house?  Catch wasps, bees, moths, flies, spiders, beetles, even earwigs, one-handed, swiftly, easily, without hurting them!  Observe the insect through the clear container, then open it to release them outside.   This is the German-made Schutzgreifer that we have been searching for. We had purchased a couple of these nifty devices and used them for years, but couldn’t find a supplier. Now we have them and you can too! They operate one-handed, like scissors: simply open, place over the insect and gently close. Even works on drapes and upholstery.

A Favorite Basil Pesto Recipe

Sweet Basil

Basil can still be planted this season, and you’ll harvest enough for many recipes. This Pesto Recipe is from Mary Lou Carlson as adapted by Carol Gerlitz (originally in Fine Cooking magazine, June/July 2001)

Yields about 1½ cups

  • 3 cups packed basil leaves (about 6-7 ounces of leaves)
  • ¼ cup ice water
  • 1 clove garlic, peeled and smashed
  • ½ cup + 2 tbsp. pine nuts
  • ¼ cup grated Parmesan cheese
  • ½ tsp. salt
  • 3/8 tsp. black pepper
  • ½ cup extra-virgin olive oil
  • Bring 2 quarts water seasoned with 1 tablespoon salt to a rolling boil. Prepare an ice bath by combining ice and water in a large bowl. (Be sure you freeze a lot of ice cubes ahead of time for this.)
