Filberts prefer consistent moisture, especially during establishment and fruiting. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly in late summer to encourage dormancy and hardening off for winter.

Prune to maintain a healthy structure, remove dead or diseased wood, and improve air circulation. Thin out suckers that emerge from the base. The best time for major pruning is late winter, before new growth begins.

Aim for an open, vase-like shape to maximize light penetration.

Filberts are typically propagated by suckers removed from established parent plants or by grafting onto suitable rootstock. Layering is also an option.

Seed propagation is less common as it does not reliably produce true-to-type varieties and may take many years to fruit.

Repotting is generally only necessary for container-grown filberts. Young trees may need repotting every 2-3 years in early spring.

Choose a pot only slightly larger than the current one and use a well-draining potting mix. Ensure good drainage holes to prevent waterlogging.
