American arborvitae

American arborvitae needs regular watering to be healthy. During the first year after planting, the tree should be watered every 2 weeks. After that, it should be watered about once a month, although more frequent watering is advisable during especially dry periods. Water deeply; a good rule of thumb is about 1" per week during the growing season. Be sure to saturate the root systems with water and check the soil in the root zone for moisture. Watering should be done early in the day so the foliage will dry out quickly and reduce disease risk.

American arborvitae (Thuja occidentalis 'Rheingold') is a medium size conifer that prefers full sunlight and ideally 6-8 hours of direct sunlight a day. It can tolerate some shade during periods of high heat but will do best in consistently sunny locations. Exposure to ample amounts of bright indirect light throughout the day will also ensure good growth. Too much direct sun in areas of intense heat can cause damage to the tree's foliage, so it is important to find the right balance for the health of the tree.

Pruning of American arborvitae (Thuja occidentalis 'Rheingold') should be done during the late winter season. Pruning is usually required on a yearly basis to maintain its natural shape and promote healthy growth. When pruning, it is important to remove branches that are weak or rub against 1 another. The best way to do this is to use sharp, sterile pruning shears and make cuts close to the trunk without severing the branch. It is also important to avoid over-pruning, as this can weaken the plant and cause disease, damage, or even death.
