Calcium aids in plant cell wall formation and structure and helps regulate nutrient uptake through the roots and movement throughout the plant.

One of the most popular growing mediums! Loved for it's unique ability to retain water yet still allow oxygen to the plants. Peat is the main ingredient in many potting mixes. Great for growing plants that requiring an acidic (lower pH) environment. Use it to add body to sandy soil. Also used to control St. Augustine Decline & Take-All Patch.

Canadian sphagnum peat moss (CSPM) is partially decomposed sphagnum moss. It’s large cell structure enables it to absorb air and water like a sponge. Although peat moss does not contain nutrients, it absorbs nutrients added to or present in the soil. It releases them over time as the plants require. This saves valuable nutrients which are otherwise lost through leaching.

Peat retains up to 20 times its weight in moisture! Please Note we cannot ship this item by regular means. We can ship large quantities. Please call for specifics.

Decomposed granite is formed from granite rock ground into small angular pieces through glacial activity. A great amendment for breaking up heavy clay soils and improving drainage. Decomposed granite sand is also a great source of minerals.

Crushed limestone is used to neutralize acidity in soils. Dolomitic lime is a slow release source of both calcium and magnesium, which improves microbial activity. Lime also helps plants use phosphorous more efficiently, which encourages root growth.

The calcium in lime aids in plant cell wall formation and structure and helps regulate nutrient uptake through the roots and movement throughout the plant. Magnesium is another essential mineral that helps in the formation of amino acids, vitamins, sugars, oils, and fats. It also encourages early growth and winter hardiness.

Humate is an important part of healthy, fertile garden soil. Adding dry humate to your soil increases areation, the ability to hold water; reduces drought and heat stress; increases water, mineral and nutrient uptake. Humate is naturally occurring unaltered oxidized lignite.

Earthworm castings are the best fertilizer on earth! Odorless & non-toxic - they improve water retention, aereation, and plant growth without the danger of burning delicate plants. Use alone or mix with soft rock phosphate or other amendments to boost root development. Or add to your pots.

Epsom salt is actually magnesium sulfate, a blend of minerals plants need for a stronger root structure and to facilitate the uptake of chlorophyll. Use as an ingredient in organic fertilizer, and in alkaline soils where magnesium deficiencies occur. Recommended by many master gardeners and landscape professionals.

Expanded shale is shale that has been fired in a kiln. As the material cools, cavities are left after gases escape, leaving porous light-weight chunks capable of absorbing water and releasing it slowly at a later time. These highly porous chunks provide aeration from within the shale particles. It's ideal for poorly aerated clay soils. You're plants will enjoy more extensive and healthier root systems than ever before.

Work Expanded Shale into all of your beds and pots. Recommended by Texas A&M.

Gypsum improves soil structure by allowing more oxygen and water to penetrate the soil. The higher water and oxygen penetration levels lead to improved root growth for stronger, healthier plants.

Gypsum also provides two key plant nutrients: calcium (20%) and sulfur (16%) for plant uptake. Gypsum is pH neutral and will not affect the pH of the soil. But it is very effective at counteracting sodium in alkaline soils.

An excellent alternative to mechanical aeration, it will loosen up compacted soils. Gypsum pellets readily dissolve into the soil. Apply in any season.

Sulfur has many uses! It is a plant nutrient and a soil amendment for correcting alkaline soils. It's also a fungicide and insect repellent.

For alkaline soils: Apply 2 to 3 lbs of Hi-Yield Soil Sulfur per 1000 sq ft and irrigate to get soil penetration. Mixing with soil is also suggested for gardening and farming. Measure pH weekly - expect integration to take 2 to 4 weeks.

Sulfur has many uses! It is a plant nutrient and a soil amendment for correcting alkaline soils. It's also a fungicide and insect repellent. Dusting Wettable Sulfur is a versatile method of controlling listed insects and diseases. Use it as a dust or wettable spray on roses, flowers, fruits and vegetables to control black spot, powdery mildew, leaf spot and rust.

Application Rates:
As a spray: 4 tablespoons per gallon

As a dust: Apply on all plant surfaces to thoroughly cover

Hydrated is lime powder that has been treated with water. It reacts with the moisture to quickly release calcium carbonate into the soil, and to lower the acidity of the soil.

Lady Bug Garden Pep Cottonseed Meal is an old-fashioned favorite fertilizer for the garden that has withstood the test of time. Garden Pep Cottonseed Meal is a high-nitrogen (7-2-1), cottonseed by-product, with a naturally low pH of 6.5. This slightly acidic pH makes Garden Pep Cottonseed Meal an excellent choice for fertilizing acid-loving plants such as azaleas, gardenias, roses, and vegetables, especially in areas where the native soil has a naturally neutral or high pH. It is also appropriate for areas where soil tests indicate the need to reduce phosphorus input. It's even known as the "Vegans’ Choice" Fertilizer because it contains no animal ingredients.

Lava sand is actually pulverized lava rock. Lava sand can dramatically improves soil structure and moisture retention. Great for heavy clay soils! Work it into your beds or just spread it on top and watch it disappear!
