watering

Large filbert should be watered about once a week, and should receive approximately 1 inch of water. It is best to water in the early morning to allow foliage time to dry before nightfall and prevent fungal diseases. To ensure the plant receives an adequate amount of water, soak the soil until it is evenly moist. Allow the top inch of soil to dry out before watering again to avoid overwatering.

sunlight

Large filbert plants thrive in areas of full sun but can also tolerate partial shade. In general, the plant should receive approximately 6-8 hours of direct sunlight per day for optimal growth and productivity. Plants grown in full sun will fruit heavily compared to plants grown in partial shade. Likewise, the addition of an artificial light source can also help supplement the light the plant needs, especially during the shorter winter days.

pruning

Large filbert (Corylus maxima) pruning should take place in late winter when the tree is dormant. Pruning should be done to remove any dead, diseased, or crossed branches as well as any branches that are growing too close to 1 another. When pruning, you should not take more than 1/3 of the tree’s live branches in any given year. Doing any more at once can shock the tree. It is also important to maintain a conical shape when pruning so that there is proper air circulation and light penetration. Finally, in order to stimulate healthy growth, remove suckers that pop up close to the base of the tree.
