American arborvitae

American arborvitae (Thuja occidentalis 'Teddy') require regular watering in order to remain healthy and prevent stress. It should be watered at least once a week during the summer with about 1.5 inches of water. Water deeply and thoroughly to ensure sufficient moisture to the root zone. Water every 3 to 5 days during hot weather when rainfall is absent. Reduce watering frequency in cooler months, however the plant should not go too long without water as this can cause it to become weak or stressed. At least a light watering should be given every 2 weeks during winter months to minimize stress.

American arborvitae (Thuja occidentalis 'Teddy') thrives in full sun to partial shade. This plant species prefers 4-6 hours of direct sunlight each day, though it can tolerate more. It is best to give Teddy more sunlight during the morning hours than later in the day to reduce heat stress. The best time to provide sunlight is from 9 a.m. to 2 p.m. This species of arborvitae is adaptable and resilient, but too much sun or too little can cause the plant to become stressed and prone to disease and insect infestations.

American arborvitae (Thuja occidentalis 'Teddy') should be pruned in late winter or early spring, while the plants are still dormant. Pruning should be done before the new growth appears or flowers start to bloom, usually around March in most climates. Prune any damaged, dead, or crossing branches with sharp pruning shears. If necessary, thin out the center of the plant to increase air circulation and light penetration.
