Water regularly, especially during establishment and dry periods. Fothergilla major prefers consistently moist, well-drained soil. Avoid waterlogged conditions, which can lead to root rot.

Deep watering is more beneficial than frequent shallow watering.

Prune immediately after flowering to maintain shape and size. Remove any dead, damaged, or crossing branches. Fothergilla major benefits from light pruning to encourage bushier growth and better flower production.

Avoid heavy pruning as it can reduce future blooms.

Propagation is typically done through softwood cuttings taken in late spring or early summer. Alternatively, seeds can be sown in autumn, but germination can be slow and erratic.

Layering is another effective method for increasing the plant.

Repot container-grown Fothergilla major every 2-3 years, or when root-bound. This is best done in early spring before new growth emerges.

Use a well-draining potting mix and a slightly larger container to accommodate root growth. Water thoroughly after repotting.
