COMPOSTS

A1 Compost

A1 Eco-Gro: We nearly always have this premier compost in stock. A1 Eco-Gro is a Class I compost made from leaves, grass, chipped branches, and beer wastes. It contains a healthy population of microorganisms and diverse nutrients.  It is very stable and will not burn or steal nitrogen. Fine-textured, low in salts, with some woody particles. Use in vegetable and flower gardens, lawns, trees, shrubs. The pH is 8.3; the
NPK 1-1-1.

EKO Compost: Made locally from forest and recycled wood products composted with egg-farm poultry manure. Use in vegetable and flower gardens, lawns, trees, shrubs. Improves soil’s physical, chemical, and biological health.

EKO Lawn Topdressing: a finer textured sifting from Eko Compost, ideal to topdress lawns following aeration and fertilizing; gets food and water-holding capacity to roots; great on perennial beds, too.

Organic Mushroom Compost: from a local organic mushroom farm. Premium food for soil life and wonderful in vegetable gardens, helps to loosen heavy soils and improve aeration and porosity. Limited quantities.

FERTILIZERS
Harlequin’s Gardens Fertility Mix: Harlequin’s blend of certified organic fertilizer, humate, rock minerals, dry molasses, land: sourced coral calcium and mycorrhizae. Great for veggie gardens and all plants. 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 soil fertility.

Yum Yum Mix: 2-2-2  Vegan/Organic fertilizer for alkaline, nutrient-poor Western soils, feeds plants and soil microbes. Made from alfalfa, cottonseed meal, kelp meal, rock dust, green sand, humate. Great for native plants, Xeriscapes. Available in large and small bags.

Richlawn 5-3-2 organic: made in Platteville, CO from poultry manure and wood wastes. Excellent for shrubs and trees and is recommended for raspberries and other small fruits. Also economical and effective for fertilizing lawns.

Alpha One Fertilizer: locally made 7-2-2. An alfalfa-based product with a high organic matter content, very high humic acid value, low pH for Colorado alkaline soils, and is non-burning. It also contains blood meal, cottonseed meal and bone meal. Excellent for vegetable gardens and lawns. 20# and 40# bags.

Age-Old Liquid & Granular fertilizers: For foliar sprays and soil application. GROW formula – great, smell-free choice for houseplants, seedlings, container gardens; BLOOM formula – supports plants ready to bloom and fruit; FRUIT FINISH – perfect at fruiting phase for berries, tomatoes, peppers, eggplants, squashes, cukes and zukes.

Fish Bonemeal – A natural source of phosphorus which is responsible for root development, fruiting and flower production in plants.

Earthworm Castings – Worm castings are soil or compost that had passed through an earthworm. What comes out contains 5x more nitrogen, 2x more calcium, 7x more phosphorus and potassium and many minerals and beneficial microorganisms all in water-soluble and plant-available forms. Worm “manure” will not burn and is safe for all plants, including houseplants. Worm castings support growth, root development, and disease resistance.

Rose Fertilizer: Down to Earth Rose and Flower Mix is our substitute for Mile Hi Rose Feed, and it looks good: OMRI Certified: Fish Bone Meal, Langbeinite minerals, Blood Meal, Seabird Guano, Rock Phosphate, Humate, Kelp.

Corn Gluten – a truly safe Weed & Feed; keeps weed seeds from growing, fertilizes with 9% Nitrogen. Lasts 6 months, Apply in March/April and again Sept/Oct for good weed suppression. Perfect for lawns.

SOIL-BIOLOGY BOOSTERS
Compost Tea: In our Vortex brewer, we make compost tea with a biodynamic compost, a mineral concentrate, kelp extract, molasses, trace minerals, etc. Compost tea increases the beneficial micro-organisms in your soil, which can bring more nutrients and water to your plants and make them stronger and better able to cope with stress. It can be used full-strength as a mild organic fertilizer, or it can be diluted in water up to 3 times as a soil inoculant. It can also be used to inoculate compost piles to make materials break down faster. Available when temperatures are frost free. Bring your own jugs, or use ours for a $1 deposit (refundable upon return).

Humate
A natural trace mineral, carbon, and humic acid soil conditioner. It is not a fertilizer, but it has a significant effect on fertility by feeding soil microorganisms that make nutrients in the soil available to plants.

Humic Acid
3% humic acid derived from Leonardite. A natural liquid product with the same benefits as Humate – soil conditioning and feeding soil microorganisms that make nutrients in the soil available to plants. It is applied as a soil drench to established beds where granular materials can’t be dug in.

Big Foot Mycorrhizae
Water soluble symbiotic fungus, combining four species of mycorrhizae with biochar, worm castings, seaweed, and rock minerals to provide a strong population of plant allies to bring water and nutrients.

Endo Mycorrhizae
Water soluble symbiotic fungus, inoculate roots to bring water and nutrients. Easy to use and very effective. Good for shrubs, trees, all plants (even cacti!); dissolve in water, wet roots.

Myke Vegetable & Herb
Enhances growth, development, and production; dust the granules on wet roots or sprinkle in seed furrow to improve germination and growth.

What You Need to Know about Front Range Soil, by Mikl Brawner

Nobody would want to spend their winter weekends pouring over soil catalogues. To humans, soil just isn’t sexy. To plants, on the other hand, soil is very intimate, and as we humans know, intimacy can be wonderful or awful. So even though we don’t have any sexy soil pictures for you, we’d like to seduce you into looking under the covers where your plants roots are sleeping, because this is where the action will be getting warmer in a little over a month.

By now, most of us know that plants get aroused by soil, not dirt. We used to think soil was just physical; stuff to hold the plant up, so we could add a strong chemical fertilizer to make that plant, or grass, grow Fast! But we’re smarter now, because we know that soil is also biological—full of fungi, bacteria, and if it’s healthy, hundreds or even thousands of different organisms—all living and dying in a mutually supportive relationship with the plants. The plants share their carbon nutrients from photo-synthesis, and the soil life shares water, phosphorus and other riches with the plants. This is symbiosis—and symbiosis is sexy, because it supports Life.

So even though there is nothing you can do at the moment, very soon, before it’s warm enough to plant, you can start making your bed sexy. Sexy soil sprouts seeds, grows roots and leaves, builds strength, makes flowers and fruit, and defends against pests.

Why bother digging and amending? Why not just plant natives and other tough plants and skip the work? You can….some plants will do OK without much help. But Colorado soils are not Iowa soils. Colorado soils are characteristically deficient in nitrogen and organic matter, and mixing certain amendments with our tight clay allows oxygen and water to penetrate. Oxygen and water are essential to support healthy soil bacteria and other soil organisms. They encourage growth and support plant health.

So how can we support the soil life? Think how Nature does it: tree leaves fall to the earth, dead stems and leaves fall over and after years of snow and decay, a rich layer forms that feeds the soil. We humans are looking for faster results, so we can add already matured compost, healthy animal manures or organic fertilizers and rock minerals, plus, if the clay is very tight, we can add expanded shale. Too much of anything is not a good thing: add 20%-30% compost to new plantings, half the recommended organic fertilizers, a handful of rock minerals, scattered, and no more than 10%-20% expanded shale.

Let the biology do a lot of the work. It’s not hard to add more later; it’s very hard to correct too much. Keep the soil covered with mulch or living plants. Even native plants appreciate some compost to hold moisture and provide a light feeding when they are young. One more thing: avoid poisonous pesticides, fungicides and herbicides, like the plague. They kill or undermine the health of your allies—the soil life. Toxic pesticides are the opposite of sexy; they are like inviting the Grim Reaper into the bedroom. There are effective, non-toxic alternatives.

What about no-till? Not turning the soil makes sense once you’ve got the soil life in a good environment. Then you don’t want to disturb the symbiotic networks. Then you can feed from the surface; good tilth and worms will take the food down.

Harlequin’s Gardens has been guiding gardeners with soil care for many years. We source our materials mostly from local suppliers, and we’re very picky: we don’t sell feedlot manure or bio-comp with human wastes, or composts that are too hot or too raw. We don’t sell chemical fertilizers because they burn the soil life, disrupt the plant-soil relationship, limit plant nutrition and contribute to global warming. Our potting mixes are expensive because they nourish plants without chemical fertilizers. Sexy soils support the health of the plants and the health of the gardener who grows and eats those plants.
