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 fertility.
We are making compost tea with a biodynamic compost, a mineral concentrate, kelp extract, molasses, etc., and it is being made in a Vortex brewer. Compost tea increases the soil life (beneficial micro-organisms), which can bring more nutrients and water to the 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. We have observed some very good results and received positive reports from customers who have tried it. Bring your own jugs, or use ours for a $1 deposit (refundable upon return).
These are the composts we carry during the season, although we don’t always have them all in stock at the same time:
Fine Woodchip Mulch: Mats tight to prevent blowing by the wind, and lets less light get to weed seeds, has more nutritive potential than cedar or redwood, decomposes rapidly against the ground
Soil Pep: Partially composted fine bark mulch, dark and beautiful, ideal for rose gardens, shrubs and perennials, premium quality for front entrances and high visibility.
We carry a range of Age Old Organics products in both liquid and dry (granular) forms with good history of success in Colorado gardens.
From our friends at Cocorado, a highly biologically active compost from Alaska with high levels of humic & folic acids, which improve nutrient uptake and water retention. More concentrated than regular compost, use sparingly. We use it as an ingredient in our compost tea. Alaskan Humus is teeming with beneficial microbes.100% Organic
A locally made organic fertilizer: 7-2-2. It is 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. Slow releasing over a long time. Feeds soil microbes.
The Soil Food Web is an important component for healthy plants. This concentrate has not only outstanding Mycorrhizae but also carriers of Biochar, kelp and worm castings. Improve water and nutrienet uptake, root growth and plant growth while reducing transplant shock and drought stress.
A natural source of phosphorus which is responsible for root development, fruiting and flower production in plants.
encourages water movement through soil and soilless media. High fertilizer use can compromise plant growth over time due to concentrated mineral salt deposits. This product is a unique rinse formula designed to remove fertilizer buildup which may relieve nutrient lockout. Derived from saponin, an extract of the Yucca schidigera plant. Can be used for both hydroponic and soil applications
Non-toxic pre-emergent weed suppressant and fast-acting organic fertilizer. It inhibits seed germination, but harmless to plants with root systems, people, worms and microorganisms. The effect can last up to 6 months and is especially useful in lawns.
Organic Healthy Grow Plant Food for Acid-Loving Plants: Derived from composted chicken manure from an egg farm, feather meal, and sulfate of potash (non-synthetic mined mineral-Sul-Po-Mag)
Organic Healthy Grow Plant Food for Tomatoes: Derived from composted chicken manure from an egg farm, feather meal, & sulfate of potash (non-synthetic mined mineral – Sul-Po-Mag)
Mined south of Boulder, then fired. A superior clay buster, loosens and aerates clay soils, holds water & air, and supports microorganisms. Excellent for Roses and Fruit Trees. Used at Texas A&M and recommended by Joan Franson, Rosarian
New Jersey Greensand: An organic source of 3% Potassium that holds moisture, has a high cation exchange capacity, and contains many trace minerals. It is a slow release product.
Texas Greensand: Texas’s finest source of organic greensand, contains 3% Potassium. This slow release product holds moisture, has a high cation exchange capacity, and contains many trace minerals.
this is a mined carbon concentrate that multiply microorganisms and has the effect of making nutrients in the soil available. We have been using this for years in our potting mixes.
This is a water-absorbing gel that absorbs 200-400 times its density in water. It is used as a soil amendment to increase the water-holding capacity of soils, reducing watering frequency by 20-40% in the ground and 50-75% in containers and hanging baskets. It greatly aids establishing of young plants, and improves soil structure, staying effective for 8 years. It has been used to help trees in drought and to reduce the water requirements of lawns. I have used this product for 12 years in producing plants from seed and found it very useful, needing very little in the soil. It is a synthetic polyacrylamide polymer that has been determined nonhazardous by OSHA, but has not passed organic standards by OMRI.
This seaweed product holds moisture, improves soil structure, provides a wide range of naturally chelated (available) minerals, adds organic matter, helps plants in stress, supports soil life and adds vitamins and plant hormones. It has been reported to help prevent fungus diseases. For roses half a cup is recommended two times a year (with the Rose Feed). Also recommended for vegetables, perennials and shrubs.
100% Guaranteed to work to repel deer and rabbits with once a month application. If they are really hungry, or if it rains more than 1″ per week, spray more often. It does not have a strong odor after it dries, is environmentally safe and also stimulates growth. NOW there is a formulation for moles and voles.
Mile Hi Rose Feed: Roses that bloom more than once a year need extra support if you want good repeat. This mostly organic rose fertilizer, formulated for Colorado soils,has proven itself for 10 years at the Boulder-Dushanbe Teahouse garden and at the private gardens of many rose society members. Its primary ingredients are alfalfa, kelp meal, bone meal, blood meal, cottonseed meal and fish meal. We recommend one cup per plant only twice (or 3 times) a year. For busy people twice a year is far better than the every few weeks for chemical fertilizers, and way better for the soil life.
Mile-Hi Alfalfa Meal: Alfalfa was called the “In food for roses,” by famous rosarian Howard Walters. It is high in protein, acts as a powerful plant growth stimulant, and supports soil microbes, releasing soil nutrients in plant-available forms. Although it is an ingredient in Mile-Hi Rose Feed, many rose growers like to use one cup of Rose Feed with one cup of Alfalfa.
Mineral-rich fertilizer containing trace minerals in a form that is readily available to plants at any soil pH. Feeds plants and soil life.
Myke has two different blends of mycorrhizae to help when transplanting. One for vegetable gardens in the green bag and one for tress and shrubs in the blue box. Both stimulate root development and phosphorous uptake while reducing watering needs.
We like these fertilizers derived from the mineral rich North Atlantic Ocean and carry several of their different dry and liquid fertilizers.
Rock dust fertilizer containing over 30 trace minerals. Great for clay, rock gardens, natives, cacti, and vegetables. Especially good for penstemons & wildflowers. Best for soil prep or side-dress every 2 years.
a 100% organic product made in Platteville from dehydrated poultry manure and beetle-kill wood wastes. Excellent for shrubs and trees and is recommended for raspberries and other small fruits. Economical and is effective for fertilizing lawns. Listed by OMRI for organic use. Ideal for lawns, trees, shrubs, annuals, perennials, vegetables and roses. Covers 2,000 sq ft for turf.
a natural source of phosphorus and calcium, immediately available over a long time. Does not reduce mycorrhizae like petroleum-derived phosphorus.
This is a rock dust product containing over 30 trace minerals. When there is not a proper balance of trace minerals, deficiencies will cause problems with plant growth. In heavy clay soils, movement of these minerals is difficult. Therefore it is good to add Planters II when doing your soil prep. It can also be broadcast around established plants every two years. Very beneficial for vegetables, native plants, cacti and succulents and for supporting a healthy soil life.
Cocorado a local woman owned business provides us with a potting soil made from coconut coir, perlite, azomite minerals, calphos, rock dust, kelp meal, oyster shell, dolomite lime, earthworm castings, mycorrhizae and Alaska humus.
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.
A 2-2-2 organic fertilizer formulated in New Mexico for alkaline, nutrient-poor Western soils like ours in Colorado. It is made from alfalfa meal, cottonseed meal, kelp meal, rock dust, greensand and soft rock phosphate. It feeds the plants and the beneficial microbes that feed the plants. Far more effective than its 2-2-2 formula implies, especially when used in conjunction with humate. Vegan: no animal ingredients.

Several years ago, our good friend and former Harlequin staffer Sequoia and his wife moved from the Boulder Valley to the Western Slope’s high desert to pursue their dream of regenerative organic farming, producing nutrient-dense food and herbs. They’ve established Root Rock Farm, where they grow or wild-collect most of the ingredients for their cottage industry, Balm Botanics artisan hemp-based infused body products, which we are happy to introduce.
Their hand-made, plant-based Synergy Salve is the result of many years of research, trialing and refining. It uses a synergistic combination of herbs and hemp infused in natural oils and waxes. They grow their own CBD hemp, which offers a full spectrum of terpenes and cannabinoids. Eve has found their salve highly effective in relieving aches and pains, very pleasantly aromatic and moisturizing. Balm Botanics’ Massage Oils are infused with sustainably wild-harvested sage from Root Rock Farm land. The combination of soothing oils, their own hemp extract and specially selected herbs promotes deep relaxation during and post-massage.
We love using Khala cloths, the original Beeswax Wraps in the US. They are the creation of Asa and Tamar McKee, who now reside in Boulder, where they produce their environmentally responsible alternatives to plastic wrap and plastic bags. Khala Cloths can be used to cover and seal a bowl of left-overs, and make the best wrapping for keeping cheeses, breads and vegetables fresh longer. Every Khala Cloth comes in zero waste packaging and the cloth used is organic cotton and hemp grown in North America – no bleaching, no chemicals! Khala Cloths will have a long life (several years) when properly cared for.
Kristina Williams is our beloved beekeeping specialist, an entomologist with more than 35 years of beekeeping experience, and an amazing wealth of knowledge. She tends hives in diverse gardens at several locations around Boulder County, where the bees collect from alfalfa, Russian olive, sunflower, apple and many other plants surrounding the small farm where she lives just off the Diagonal in Longmont.
This year she’s bottling up some of her liquid gold to sell exclusively at our Holiday Gift Market! It tastes divine!
Catch wasps, bees, moths, flies, spiders, beetles, and even earwigs one-handed, swiftly, easily, without hurting them. Then observe them closely through the clear container, before releasing them outside.
This is the German-made Schutzgreifer that we have been searching for. They operate one handed like scissors: simply open, place over the insect, and gently close. Even works on drapes and upholstery.
As far as we know, we are the only source for this tool in the whole of the United States!
Yay – totally organic! Made in Boulder by herbalist Debra St. Claire! No corn syrup! Delicious! Effective! Packaged in pretty, reusable tins! Incredibly inexpensive!
This very small, extremely high quality 12x power magnifier is great for getting a closer look at what’s bugging your plants, taking out splinters, or helping to identify flowers.
The Spanish word ‘trementina’ has come to be used as the name for the sap of the pinyon tree of New Mexico. Folk remedies made from this sap have been used for centuries to relieve dry, cracked skin, abrasions and scrapes, and for drawing out splinters.
Made in New Mexico’s ‘curandera’ tradition by our friend Pamela, who climbed the pinyon trees to gather the sap, and infused it in olive oil and New Mexico beeswax to create this rare traditional salve. Each tin of salve comes in a lovely organza gift bag.
