How (& Why)to Use Silica On Houseplants
Silica: Strengthens cell walls. Supports stronger defences, and builds resistance to pests. Helps grow broader stems. Broader stems can then support bigger leaves. Reduces digestibility – it becomes too hard for pests to eat, so they go elsewhere. Reduces the risk of abiotic shock (such as heat or drought shock)
