Veggies, Seeds, Special Events, and Classes!

April 3, 2019

VEGGIES, SEEDS, SPECIAL EVENTS, & CLASSES!

So many opportunities this spring!

Harlequin’s Gardens offers a lot of exceptional and unusual varieties of veggies that you won’t find anywhere else!  Our selection of cool-season veggies continues to expand daily as do our perennials.  There are many veggies, including onions, leeks, Asian greens, bok choy, and heading type of brassicas (broccoli, cauliflower, cabbage) that will yield larger and better results if they are planted sooner, rather than later in the season.  (Eve with Graffiti Cauliflower, right.)  See our website for many of our veggie descriptions.  

This is also the best time to get many types of seeds in the ground.  Our collection of Botanical Interests, Seed Savers, and Beauty Beyond Belief seeds contain many interesting and heirloom varieties for you to try.

If you’re unsure about the best ways to approach veggie gardening, or want to expand your knowledge, we have two classes this weekend that will be of great help.  On Saturday at 10 AM, our own Mimi Yanus will guide you in her popular “Getting Started in Veggie Gardening” class.  Then, at 1:00, Tracy Parrish follows with her “Succession Planting” class where you’ll learn how to maximize your garden space and keep your veggie garden in continual production. 

On Sunday at 1:00, Mikl will share how you can have a successful lawn without using toxic chemicals in his “Organic Lawn Care” class.   See below for more details and call 303-939-9403 to reserve your seat!

As of April 1 we’re now OPEN DAILY from 9 AM to 5 PM, and until 6 PM on Thursdays. 




POTATO STARTS 

… will be arriving late next week!  This year we will have German Butterball, Kennebec, Mountain Rose, and Purple Majesty selections.  See our website for descriptions! 

 




GOOD NEWS SPECIAL EVENT!

Neighbors, farmers, gardeners, citizen activists, the politically weary, the financially skeptical, the poetically inclined, pollinators, seed savers, CSA members, folks who want to know where their food comes from and where their money goes, and all who would like to put the culture back into agriculture and the civil back into civilization, all who would like to make our community healthier and our soil more fertile (which, as fate would have it, also pulls carbon out of the atmosphere, go figure!), all who take to heart the morning news reports about the collapse of insect populations and the urgency of climate change and who are no longer content to place all our bets on distant markets and distant political solutions. . .yes, you, us, we of Boulder, of the Front Range, of the environs between the Great Plains and the Continental Divide. . . we’re coming together to enjoy

—ADMISSION FREE—

. . .which could stand for Americans for Healthy Agriculture (AHA!), but doesn’t, because there is no such organization, but it stands for bunches of us coming together in a spirit of radical neighborliness, and for AHA! moments towards which we are heading, courtesy of these festivities, CO-HOSTED BY SOIL (Slow Opportunities for Investing Locally) and HARLEQUIN’S GARDENS, with help from our friends at Boulder County Farmers Markets, Savory Institute, Fresh Thymes Eatery, Organic Sandwich Company, Backpacker’s Pantry, Charlotte’s Web, and 78 individuals (on our way to many more, we trust) who have begun making 0% loans to local farmers and food enterprises, in the name of diversity and health, in the name of relationships putting transactions in their place, a small token of the esteem in which we hold those who are tending the soil and building the local food system. . .So, you are cordially invited to join in an afternoon of shared learning and community celebration, along with a few words from

and others, and. . . including poetry, music and other forms of cultural invigoration and mutual appreciation. Conviviality! Conversation! Door prizes! Radical neighborliness!

Who knew?! Something is afoot! AHA!

HARLEQUIN’S GARDENS 2021 SPRING NEWSLETTER

March 25, 2021

Welcome to Spring, to Harlequin’s Gardens and to another year of the challenges and joys of being alive on Earth, along with the opportunities, work, and healing rewards of gardening. It is both curious and common sense that as we nurture, we ourselves are nurtured.

One of the most powerful and telling lessons of 2020 has been how intimately we are all connected with each other. Now we are all aware that we share air and biology with the whole world. Our human bodies are, in reality, half human cells and half microbial cells. And these microbial partners do contribute to our digestion, immune system and even cognition. And the balance of organisms depends on who we are in contact with and what we are eating. [Read More]

Additional Mason Bee Class

March 18, 2019

Additional Mason Bee Class by Popular Demand!

Call today to reserve your spot!

We’ve had such a popular response to our two Mason Beekeeping classes with Tom Theobald, that’s he’s agreed to add a third class next weekend!  On Saturday, March 23 at 10:00 AM, Tom will discuss the importance of native bees and the roll they play in pollinating our early crops.  You will also have the opportunity to purchase Mason Bee Straws (see details below as this must be done in advance.)

Tom’s class will be followed at 1:00 by Kristina Williams’ class on “Get Equipped for BeeKeeping”, which is Free!  Kristina will share how to build strong frames, and give a our of our Bee Barn.  A great combination with Tom’s class!  

Call 303-939-9403 to reserve your seat!

Sat, Mar 23 at 10 AM
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.) 

Sat, Mar 23 at 1 PM 
Get Equipped for Beekeeping with Kristina Williams  

For beginning and established beekeepers, alike!  Kristina will demonstrate how to build and crosswire frames. Learn the lingo of beekeeping supplies and take a tour of our Bee Barn. Harlequin’s Gardens is upgrading frames and foundation to be as strong as they can be and still use beeswax. Our resident entomologist and Bee Barn Babe, Kristina Williams, will share her vast knowledge with you!  Free Admission!   (Photo credit, right: Red Hot Pepper)

Cool-Season Veggies are Here!

March 12, 2019


With asparagus and onions arriving soon!

Now that our cool-season veggies have begun to arrive (see list below) it feels like spring will be here very soon! We are also stocked with seeds for early spring crops (see list below).  We look forward to having you stop by to see them. 

When planting in the early season, it’s important to have a few extra tools on hand.  Soil Thermometers will help you accurately gauge when to plant.  

Row Cover gives you a few degrees warmer temperature, protection from drying sun and wind for seed beds, tender seedlings and transplants, as well as protection from insects and birds. The fabrics can be “floated” over your rows or beds, using weights of various kinds to keep them in place, and can also be used to cover garden tunnel frames. When handled gently, these fabrics can last several seasons.   We have two types of Row Cover fabrics – Ensulate (1.5 lb.) and Seed Guard (.6 lb), both in pre-cut sheets or custom cut from our 12′-wide rolls.  [Read More]

We Have Soil Products for You!

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. 

Sun, Mar 10 at 1 PM

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.

Eko Lawn Topdressing

Finely screened compost perfect for top dressing lawns after aeration.  Holds moisture next to the roots increasing drought tolerance. Supports microorganisms. 

Symbiosis Potting Soil – NEW! 

Symbiosis Potting Soil is a plant-based compost, made from coconut coir, perlite, azomite minerals, calphos, rock dust, kelp meal, oyster shell, dolomite lime, earthworm castings, mycorrhizae and Alaska humus.     



Fort Vee Potting Mix – NEW!  

This compost-based potting mix is best for starting seeds and transplanting seedlings and houseplants. It is composed of composted manure and plant material, peat moss, crushed granite and basalt, blood meal, kelp meal, bone meal, gypsum, vermiculite, coconut coir and biodynamic preparations. It’s best to wet before use. Used very successfully last year at Kilt Farm.  

Ocean Forest Potting Soil

A nutrient-rich soil for planting seedlings. It performed well in our tests. Contains: composted bark, sphagnum peat, fish emulsion, crab, earthworm castings, loam, perlite, bat guano, granite dust, kelp meal.


EcoPett

A natural pine coop bedding (or cat litter!). Contains recycled beetle-kill pine and activated carbon, making it very absorbent, with powerful odor control. It outperforms and outlasts hay and wood shavings. Expands up to 5X when wet. Reduces cleaning by 50%. Not a soil amendment, but a local, recycled beetle-kill pine product to help care for your poultry and other small animals.




Products Coming Soon!

Harlequin’s Fertility Mix

A mix of Biosol Certified Organic 6-1-1 Fertilizer, humate, molasses, endomycorrhizae, and calcium. Increases root mass, top growth, soil life, and productivity naturally.  This is not just a fertilizer. The combination of ingredients and mycorrhizae act synergistically to support fertility.  It has received rave reviews!  Try it and let us know your experience. 

Rocky Mt. Minerals

From Salida, this broad spectrum of many different minerals that support plant strength and immune function, including 11% Calcium, 6% Sulfur plus magnesium, iron, and many others. The big difference with this product is that its geothermal source makes these minerals much more available. 

Mushroom Compost

From a local mushroom farm.  Dark, rich humus that feeds soil life, improves soil structure & aeration, saves water. Great soil amendment for veggies, perennials, roses & shrubs. Also, a superb mulch for roses. 

Dairy Cow Manure Compost

Nutrient-rich compost made from manure of dairy cows – NOT fed hormones and only given antibiotics when sick. (No rBGH given.)  

Coco Loco Potting Soil

A superior coir-based potting media produced from coconut husks, making it one of nature’s most abundant renewable resources.  This mix also contains earthworm castings, bat guano, kelp meal and oyster shell.  It resists compaction, easily rewets, and absorbs evenly for excellent aeration and maximum drainage.

Biochar

A highly adsorbent, specially-produced charcoal applied to soil as a means to increase soil fertility and agricultural yields and sequester carbon.

“Alternatives to Glyphosate” – NEW! 

Glyphosate is the main ingredient in Roundup herbicide, and a probable carcinogen. This resource is derived from the latest scientific research.  

“IPM for Cannabis Pests” – NEW!

Registered insecticides are illegal and toxic pesticides make no sense.    

Insect Saver – NEW! 

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.

For Your Fall Vegetable Garden

September 1, 2025

It’s time to plant ‘cool-season’ crops! And for your tomatoes, peppers and eggplants, this is a great week to feed them with Neptune Tomato and Vegetable Fertilizer – well-fed plants provide a better harvest!

Chinese Cabbage, Tokyo bekana.  A community garden favorite last season!
Bright Lights Swiss Chard. Multi-colored mix. Not frost tolerant; row cover extends your harvest.
Shanghai Green Pak Choi. Light green leaves, mild flavor, crisp texture. Great for soup, stir-fry and salad.
Red Giant Mustard Greens. We mean giant! Give it room. Cold tolerant.
Lavewa Spinach. Open-pollinated with rich, deep color.
Piracicaba. Lots of mini-florets on this non-heading broccoli.
Yukina Savoy, Asian Greens. Mild, sweet flavor.

We also have  cool-season veggie seeds, as well discounted summer vegetable and flower seeds for a head-start next year. Consider Row Cover Fabric for frost and insect protection.  Garlic and Shallots should arrive soon!
