Why does your Dryopteris bushiana have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Dryopteris species are understory plants that require high ambient moisture; dry air causes the delicate frond tips to desiccate quickly.
Allowing the growing medium to dry out completely between waterings stresses the fern, leading to necrotic tissue at the extremities.
Excessive buildup of salts from tap water or fertilizers can burn the sensitive tips of the Bush Fern fronds.
Direct sunlight can overheat the fronds of this shade-loving species, causing localized thermal damage and browning.
