Especially useful for bonsai trees, calcined clay can also be incorporated into mixes for succulents, cacti, and other container-grown plants that benefit from an open, well-structured growing medium. Calcined clay provides an excellent alternative to akadama, which is expensive as it is imported from Japan. Key Benefits: Ideal for Bonsai Soil Mixes: A versatile inorganic component for creating custom bonsai substrates. Supports Drainage & Aeration: Granular particles help maintain pore space within the growing medium and allow excess water to drain. Porous Structure: Calcined clay can absorb and retain some moisture while maintaining an open soil structure. Helps Resist Compaction: Durable particles help create structure in mixes that might otherwise settle or become dense. Versatile Soil Amendment: Suitable for bonsai, succulents, cacti, container plants, and custom specialty soil blends. Easy to Mix: Combine with pumice, lava rock, bark, compost, or other growing-media ingredients according to your plant's needs. What Is Calcined Clay?Calcined clay is clay that has been heated at high temperatures to create a hardened, porous granular material. Unlike untreated clay, the resulting particles maintain their structure when incorporated into growing media.This combination of porosity, drainage, moisture retention, and structural stability makes calcined clay especially useful as an inorganic component of bonsai soil. Why Use Calcined Clay for Bonsai? Bonsai trees are grown in relatively shallow containers, making the physical structure of the growing medium especially important.Calcined clay helps create a granular substrate with spaces between particles for water movement and airflow. Its porous particles can also retain some moisture, helping growers balance drainage with moisture availability.It can be incorporated alongside other commonly used bonsai substrate components such as pumice, lava rock, pine bark, and organic material to create a mix appropriate for the tree species and growing conditions How to Use Calcined Clay: Soil Amending:Blend 10% - 30% calcined clay into potting soils for houseplants, container gardens, or raised beds.Evaporation control:Top dress the surface of existing soil with a thin surface layer to slow down moisture loss. Where Can I Use Calcined Clay?Bonsai Soil:Use as one component of a custom bonsai substrate. Combine with other inorganic or organic ingredients according to the needs of your tree.Succulents & Cacti:Mix with other growing-media ingredients to create additional structure and drainage.Custom Soil Blends:Combine with pumice, lava rock, bark, perlite, or other amendments to create a specialty growing medium. How Much Calcined Clay Do I Need?Choose the bag size that best fits your potting or repotting projects. The appropriate proportion will vary depending on the plant species, climate, container, watering habits, and other ingredients in the mix. 4 qt: Bonsai repotting, small plant collections, or custom soil mixing.   Why Choose Soil Sunrise Calcined Clay Bonsai Soil Additive?

Horticultural Grade Rice Hulls

Lightweight Organic Soil Amendment for Aeration, Drainage & Potting Mix Structure Create a lighter, more open growing medium with Soil Sunrise Horticultural Grade Rice Hulls. These lightweight plant-based particles can be mixed into potting soil and custom growing media to increase air space, improve drainage, and help reduce compaction. Ideal for houseplants, vegetables, herbs, flowers, raised beds, container gardens, seed-starting mixes, and custom potting blends, rice hulls provide a natural alternative for growers looking to add structure and porosity to their soil. Key Benefits: Improves Aeration: Helps create additional pore space throughout potting mixes for a lighter, more open growing medium. Supports Drainage: Adds structure that allows excess water to move more freely through the soil. Lightweight Soil Amendment: Adds structure without significantly increasing the weight of containers or potting mixes. Versatile Growing-Media Ingredient: Suitable for houseplants, vegetables, herbs, flowers, containers, raised beds, and custom soil blends. Easy to Mix & Use: Blend with potting soil, peat moss, coconut coir, compost, or other growing-media ingredients. What Are Horticultural Rice Hulls?Rice hulls are the lightweight outer coverings removed from rice grains during processing. In horticulture, they can be incorporated into soil and potting media as a plant-based structural amendment.Their shape and lightweight texture help create spaces within the growing medium, improving airflow and drainage while reducing the density of heavier soil mixtures. Unlike mineral amendments such as perlite or pumice, rice hulls are an organic material and will gradually break down over time. How to Use Horticultural Rice Hulls: Prep the pot: Clear debris and fluff the top layer. Blend into mix: Blend hulls at ~¼ volume with potting mix or garden beds. Top-dress: Spread a 2" blanket over finished plantings. Water thoroughly: Soak the amended soil so hulls settle and begin releasing nutrients. Refresh seasonally: Add a light layer or mix in fresh hulls each spring to maintain drainage and fertility. Because rice hulls gradually decompose, growing media may be refreshed or amended again over time as needed. Where Can I Use Horticultural Grade Rice Hulls?Indoor Houseplants:Mix into potting soil to create a lighter, more aerated growing medium.Vegetables & Herbs:Incorporate into container mixes, raised beds, or garden soil to add structure.Flowers & Ornamentals:Use in potting mixes for flowering plants and ornamental container gardens.Seed Starting & Propagation:Add as one component of a lightweight growing medium when additional aeration is desired.Raised Beds & Container Gardens:Blend with soil, compost, and other amendments to help maintain a loose soil structure.Custom Soil Blends:Combine with peat moss, coco coir, bark, compost, or other growing-media ingredients when creating your own specialty soil blend. How Much Horticultural Grade Rice Hulls Do I Need?Choose the bag size that best fits your potting or repotting projects. The actual amount needed will vary depending on container size, proportion of rice hulls used, and how much growing media is needed for each plant. 4 qt: Several houseplants, containers, or small soil-mixing projects.8 qt: Larger plant collections, raised beds, or frequent soil blending.
