Weeping trees can vary from the small indoor weeping fig to the giant outdoor weeping willow. Many trees come in regular and weeping forms, but their care is not much different. Most weeping trees don't require intense care and can make stunning additions to a landscape, especially around water features. Some of these trees, such as the weeping cherry varieties, are known for their spring flowers. Most outdoor weeping trees can be grown throughout the United States.
Water indoor weeping trees as soon as the soil starts to feel dry. Give the plant water until it comes out the bottom drain holes each time. Water outdoor trees once a week during their first growing season. Give extra water to young trees during very hot, dry times. Water established trees only during times of drought.
Spread a 2-inch layer of compost over the root system of indoor and outdoor trees each spring.
Keep the area under the canopy of the tree weed free. Lay down a 4-inch layer of organic mulch under the tree to keep weeds from growing, help to retain moisture and add nutrients to the soil. Keep the mulch at least 4 inches from the trunk and hand-pull weeds that grow there.
Apply fertilizer when a young tree starts growing or every spring for outdoor trees. Fertilize indoor trees each spring until early fall when the tree starts to grow new leaves. Follow manufacturer's directions for dosage details. Flowering trees will need a slightly different fertilizer than foliage trees.
Prune indoor trees to keep them a desired size. Cut back outdoor trees to allow sun and air circulation to the center of the tree. Trim weeping tree branches to allow foot traffic under the canopy, if desired. Prune in late winter before new buds appear. Cut dead and damaged branches off at any time.
