Water American hazelnut deeply and thoroughly but infrequently. Generally, it should be watered 2 to 3 times per month and should receive 1-2 inches of water a watering. The best time of day to water is in the morning. This ensures that the soil has adequate moisture for the entire day, while also providing the plant plenty of time to dry. Watering should be done slowly to allow the water to soak into the ground and reach the roots, as opposed to running off.

American hazelnut plants prefer full sun to partial shade, with at least 4 to 5 hours of direct sunlight per day being ideal. Too much direct sunlight can cause the plant to scorch, so providing some midday shade is beneficial. In areas with hot summers, dappled or light shade is ideal during the hottest part of the day. American hazelnut trees are adapted to most climates, and thrive in USDA hardiness zones 3 through 9.

American hazelnut plants should be pruned annually to maintain a healthy and attractive shape and ensure long-term productivity. Pruning should begin after the plant has gone dormant in late autumn or early winter, just after the leaves have dropped. Prune away dead, diseased, or damaged branches and shoots, and trim back overly long or straggly branches. Pruning is best done no more than a few days after a rainfall, since the wood will be more supple and easier to work with. American hazelnuts should not be pruned heavily, as this may reduce the yield of nuts produced. For an established plant, pruners may choose to thin out the top growth and reduce the overall size of the shrub.
