Watch out for

Rhizome spread: Install deep root barriers and consistently cut back fronds before spores are released to weaken the plant.

Spore dispersal: Remove and burn or bag fronds before they turn brown to prevent new colonies from establishing nearby.

Soil acidification: Raise soil pH with lime if cultivating other species, as bracken prefers and indicates acidic conditions.

Nutrient depletion: Clear established patches thoroughly and mulch well to restore soil fertility for desired plants.
