Worm castings are an ideal way to promote healthy plant growth due to the nutrients that they provide. They are so beneficial that some gardeners refer to worm castings as “black gold.” These benefits include concentrated nitrates, phosphorus, magnesium, potassium and calcium. Unlike animal manure and chemical fertilizers, all of these minerals go directly to the plant instead of having to be broken down first. They also improve soil quality as a soil amendment by increasing absorbency, releasing beneficial b@cteria and m1crobes and providing natural filtration of waste. Worm farm castings can also be used as food in hermit crab care as a supplemental feed source.BENEFITSProvides slow release fertilization to your plantsProvides nitrates, potassium, magnesium, calcium and phosphorusAll natural, no chemicals or additives; safe to use in organic gardeningHelps dirt to retain moistureProvides natural filtration of noxious substancesPopular for indoor use as they don’t introduce bugs, etc. like fresh compost or manureEncourages beneficial b@cteria and m1crobesTIP: Replenish nutrients and stimulate beneficial activity with extra castings once per month.INGREDIENTS: Organic earthworm castings

Calcined clay is similar to vitrified clay which can be used for the same functions. Calcined clay provides an excellent alternative to akadama, which is expensive as it is imported from Japan. Tips/Guidelines: Basic bonsai mix: 50% calcined clay, 25% lava rock and 25% organic compost Tropical bonsai mix: 40% calcined clay, 25% lava rock and 35% organic compost Deciduous bonsai mix: 50% calcined clay, 30% lava rock and 20% organic compost Conifer bonsai mix: 60% calcined clay, 30% lava rock and 10% organic compost

Rice hulls are one of the most sustainable soil additive available for improving drainage, water holding capacity and aeration. They make a great alternative to vermiculite or perlite. Rice hulls are nontoxic and biodegradable, so they feed the soil as they break down. However, they are stable enough to last for the typical gardening season before decomposing, so the soil will enjoy the benefits of moisture regulation and aeration while your organic vegetables grow. They are also great for terrariums and chicken bedding. Though rice hulls don’t last as long in the soil as vermiculite or perlite, they are a sustainable product that turns food waste into a garden soil amendment and doesn’t involve mining raw materials from the ground. TIP: For your garden, spread about a two-inch layer of rice hulls across the surface when you fertilize your garden plot in the spring. INGREDIENTS: Horticultural grade rice hulls
