Weeping cherry trees are among the most dramatic, beautiful flowering trees. They have long, thin branches that bow down, sometimes reaching the ground. Planted by a lake or pond to show their reflection and drop their tiny blossoms on the water, they can be one of the most relaxing scenes you can imagine. There are many kinds of weeping cherry, Higan being one of the more popular and larger trees, and snow fountains being a popular smaller variety. These trees are hardy in gardening zones 4 or 5 through 8.
Choose a location that is in full sun and is not a low area in your landscape. This tree does not like to sit in waterlogged soil. Plan planting for spring to give the roots time to get established before winter.
Dig a hole twice as wide and deep as the root ball. Amend the dug out soil with 1 part compost and 1 part peat moss added to 1 part original soil. Scrape the edges and bottom of the hole with your shovel to loosen the soil.
Fill the hole halfway with the amended soil and put in your tree. Try not to disturb the roots as weeping cherries have a sensitive root system.
Fill around the root ball 2 inches with soil and then water in to compact the soil around the roots. Continue to fill another 2 inches and water until the root ball is completely covered and the soil is level with the surrounding ground.
Water every other morning for the first three months to allow the roots to become established. Then cut the watering back to keep the soil moist. This might be once a week in cooler weather or three times a week during hot, dry weather.
Cover the area under the entire circumference of the tree with 2 to 3 inches of mulch. This will not only help to hold the moisture around the roots but will help to keep the soil under the tree loose and well-draining. Replace the mulch as it decomposes each year.
Prune suckers off the tree immediately. Weeping cherry is grown on a root stock that will produce suckers from the trunk of the tree. They are easily identified because weeping branches bow down and the root stock branches will grow straight up. Cutting them as soon as you see them will cause less stress and damage to the tree.
Fertilize the tree in the fall only if it shows signs of slow growth or smaller-than-usual leaves. Flowering trees do not normally need fertilizing, especially if you add an organic compost to the soil each year. If you use manure, make sure it is well rotted and doesn't touch the trunk when you work it into the soil.
