Tropical Plant Mix

The 13 Tropical Plant Mix Soil Amendments

Each amendment links to our dedicated amendments section, with more details about that specific amendment. Below, we've included the exact ratios, with a link to each amendment in our storefront, so you, too, can craft the perfect super soil blend.

1. Coco Coir: Coco coir, derived from the fibrous husks of coconuts, is a sustainable and pH-neutral amendment that enhances soil aeration and moisture retention. Its lightweight nature promotes root health and prevents soil compaction, making it ideal for seed starting mixes and container gardening.

2. Worm Castings: Worm castings, the end product of earthworm digestion, are a nutrient-rich, organic soil amendment. Acting as a natural fertilizer, they enrich the soil with essential nutrients, including nitrogen, phosphorus, and potassium, while also improving soil structure and microbial activity.

3. Perlite: Perlite, a volcanic glass that has been heated and expanded, is valued for its ability to aerate the soil and improve drainage. Its lightweight and porous nature makes it an excellent choice for preventing soil compaction, particularly in heavy clay soils or potting mixes.

4. Vermiculite: Vermiculite is a mineral that expands when heated, offering excellent moisture retention and aeration properties. It helps to create a more consistent moisture level in the soil and is particularly useful for seed germination and rooting cuttings.

5. Bone Meal: Bone meal, made from ground animal bones, is a slow-release source of phosphorus and calcium. These essential nutrients support root development and flowering, making bone meal an excellent amendment for bulbs and flowering plants.

6. Rice Hulls: Rice hulls add structure and improve drainage in soil blends. Their silica content can also deter pests. Biodegradable and sustainable, they're an excellent alternative to perlite for those seeking more eco-friendly options.

7. Azomite: Azomite is a natural mineral product that provides a broad spectrum of over 70 trace minerals. These micronutrients are crucial for plant growth and health, promoting vigor, disease resistance, and higher yields.

8. Feather Meal: Feather meal, a by-product of poultry processing, is a high-nitrogen, organic fertilizer. It slowly releases nitrogen into the soil, encouraging lush vegetative growth and green, leafy plant development.

9. Kelp Meal: Kelp meal, derived from seaweed, is rich in micronutrients and plant hormones. It boosts overall plant health, increases resistance to stress, and enhances growth and yield, making it a valuable addition to any soil blend.

10. Langbeinite: Langbeinite is a natural mineral that supplies plants with potassium, magnesium, and sulfur, three essential nutrients for plant health. It's especially beneficial for crops that demand high potash levels and those grown in magnesium-deficient soils.

11. Oyster Shells: Crushed oyster shells are an excellent source of calcium, which helps to balance soil pH and build strong cellular walls in plants. They also improve soil drainage and structure, making them beneficial for both garden beds and container plants.

12. Orchid Bark: Orchid bark, typically made from fir or pine, provides excellent aeration and drainage. It's ideal for orchids and other epiphytes that require loose, well-draining soil to prevent root rot and support healthy growth.

13. Mycorrhizae: Mycorrhizae are beneficial fungi that form symbiotic relationships with plant roots, enhancing water and nutrient uptake. Incorporating mycorrhizae into your soil can significantly improve plant health, drought resistance, and nutrient absorption.
