Hackberry (Celtis occidentalis) plants will respond positively to a regular watering schedule. During the early spring through mid-summer months when the plant is actively growing, water about twice a week. During hotter weather or periods of rapid growth, increase the frequency of watering. During fall and winter months, water less frequently, or only when the soil gets dry. Aim to keep the soil consistently moist but not overly wet. Avoid overwatering; soggy soil may cause the roots to rot. Ensure the soil drains well, and always empty the drainage saucer after every watering.

Hackberry (Celtis occidentalis) is an adaptable plant species typically found in open areas with plenty of sunshine. Optimal growing conditions for a hackberry require at least 6 to 8 hours of direct sunlight each day for optimal growth and production of fruit. When the days begin to shorten towards the winter season, hackberry should still receive a minimum of 4 to 5 hours of direct sunlight each day. In areas with frequent cloud cover, it is best to supplement the sunlight with some form of artificial lighting.

Hackberry trees should be pruned in late winter or early spring, when the tree is still dormant. The amount of pruning should be limited in order to maintain the natural shape of the tree. Dead, rubbing and crossing branches should be removed while cutting back the branches at a point where 2 branches meet. Branches that are too dense with foliage and do not permit circulation should be thinned out. Pruning should be kept to a minimum, and only the most necessary branches should be removed.
