Horticultural sand – coarse mineral grit for custom substrate recipesHorticultural sand gives a mix extra mineral texture and weight. It is most useful in measured amounts, especially where a potting blend feels too soft or too light.What it does in use Coarse grit: changes texture without turning to sludge Extra weight: helps small pots and top-heavy plants sit more firmly Mix adjustment: pairs with soil, bark, pumice or perlite Small doses: too much sand can make a pot dense Starting ratioUse small amounts in succulent blends, bonsai recipes or custom mixes that need more grit. Combine it with true structure ingredients such as pumice, lava rock, bark or perlite so air spaces remain open.What it’s made fromVery fine sand can fill pores and reduce airflow. Use a coarse horticultural grade and keep the total proportion modest for indoor containers.How to use Horticultural sand Grit: Adds weight and reduces water-holding in mixes for dry-growing plants. Texture: Use to keep fine roots from sitting in soggy soil. Mixing: Best as a smaller fraction in a blend, not as the whole medium. Prep and handling for Horticultural sand Rinse: A quick rinse removes fines so water moves evenly through the mix.
