Harlequin’s Garden 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 fertility.
Harlequin’s Gardens Compost Tea
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).
Bagged Composts
These are the composts we carry during the season, although we don’t always have them all in stock at the same time:[Read More]
Bagged Mulches
- 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.
- Walden’s Garden Mulch: for mulching perennials, shrubs and vegetable gardens. Sprinkle some organic fertilizer on the soil, then apply mulch 1”-3” thick. Holds moisture, resists weeds, and feeds worms and microbes. Contains 5-8 year aged beetle-kill wood chips. This forest humus mulch is so broken down that we are planning to use it this year to mulch our veggie garden. We do sell straw because straw breaks down in one season. Most wood chips are so raw that it is not advisable to turn them into the soil, because they cause a nitrogen deficiency until they break down.
Age Old Dry Fertilizers
Organic fertilizers that are slow release and long lasting. They are designed to build soil fertility and increase the soil life. These can worked into the soil at planting or used as a side dressing.
Age Old Liquid Fertilizers
Organic fertilizer concentrates with good history of success in Colorado.
Age Old Bloom: 5-10-5 organic fertilizer concentrate that stimulates early growth, greater flowering and better fruit set. Use as a foliage spray or soil drench. It is odorless so can be used on house plants.
Age Old Calcium: Supplies plants with an effective source of calcium and helps correct calcium deficiencies in the soil.
Age Old CalMag2: Calcium and Magnesium fertilizer supplement designed to prevent and correct problems that can arise from deficiencies, such as blossom end rot in tomatoes.
Age Old Fish and Seaweed: 3-3-2 – a good quality fish emulsion with kelp. Loaded with macro nutrients, trace elements and bio-stimulants. It is effective to reduce plant stress and to stimulate root development
Age Old Grow: 12-6-6 fertilizer concentrate that stimulates vegetative growth. The higher nitrogen content enhances plant growth. Good forgetting vegetables up to size before fruiting and for grasses and foliage plants. First use Grow, then switch to Bloom for flowering and fruiting.
Age Old Kelp: this seaweed concentrate is a very mild fertilizer, good as a foliage spray for small plants and for plants in stress and to use in the fall to help prevent frost damage. As a soil drench, it helps to restore biological life to depleted or poisoned soils. I’ve used it for years.
Alpha One
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.
Biosol
a fertilizer that is 90% fungal biomass, 6-1-1, made from organic soybean meal, org. cottonseed meal, sucrose, lactose and trace minerals; holds water and stimulates soil life; without salt, non-burning, weed-free. Applications of BIOSOL are recommended only one or two times per year as nutrients are released throughout the growing cycle, reducing application costs. 50 lb bag.
Bone Meal
A natural source of phosphorus which is responsible for root development, fruiting and flower production in plants.
Corn Gluten Meal
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.
Dave Thompson’s Organic Healthy Grow
Dave Thompson’s 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)
Dave Thompson’s 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)
Dry-Grow
8-4-1 with 1% Calcium This is good for enhancing plant growth. Like liquid Grow, but longer lasting support for plants. Most of our soils are low in nitrogen. Contains meat and bone meal, rock dust, composted poultry manure, blood meal, and humic acid.
Dry-Fruit
2-10-20 with 1% Calcium. This is formulated for flowering plants and fruit-bearing bushes and trees. This combination builds stronger root mass and stems, produces healthy foliage and larger fruits. Contains meat and bone, composted poultry manure, blood meal and potassium sulfate.
GreenCure
Organic protection and correction of fungus diseases. This is a product that has been tested commercially for 9 years and is just out for homeowners. It is an alternative to toxic fungicides and has proved effective against powdery mildew, blackspot, rust and others. The research I have studied sounds like a genuine breakthrough, and well-proved in practice. Stan Griep of the Loveland Rose Society raves about it.
Greensand
Greensand, New Jersey: 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.
Greensand, Texas: 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.
Humate
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.
Hydrosource
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.
Iron-Rich 3-2-1 Fertilizer
10% available iron, 5% sulfur. Brings back chlorophyll to chlorotic maples, oaks, lawn, etc. Made from poultry manure, chelated iron and ferrous sulfate. Allowed for use in organic production when used for iron deficiency. Will stain sidewalks if not washed off.
Kelp Meal
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.
Liquid Fence
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
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 Boost
Mineral-rich fertilizer containing trace minerals in a form that is readily available to plants at any soil pH. Feeds plants and soil life.
Neptune’s Harvest Organic Fertilizers
These liquid fertilizers are certified for organic use. We carry Seaweed, Fish & Seaweed, and their Rose and Flowering Formula.
Planters II
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.
RichLawn
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.
Rock Phosphate
a natural source of phosphorus and calcium, immediately available over a long time. Does not reduce mycorrhizae like petroleum-derived phosphorus.
Rocky Mountain Minerals
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.
Soil Pep
This is a semi-fine mulch made in Colorado. Jamie Steelman, who gardens in Denver with 1600 roses, says, “The most important thing in my garden culture is the Soil Pep … I put about 10″ of it on top of each garden after everything is growing, and it keeps my garden almost work free.”
Squeegee
This is a fine gravel that rock gardeners use to top dress their plants. It makes a great mulch for plants that do not like to have their “crowns” wet, like penstemons and other drought tolerant and alpine plants. It does a good job of holding in moisture. In 2002 during the worst drought in 200? years, we planted two gardens in July and as they began to decline we mulched them with 2″ of squeegees. It worked!
Worm 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.
Yum Yum Mix
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.
