Tolerant of both alkaline and clay soils, the Schubert chokecherry matures 20 to 30 feet tall and 15 to 22 feet wide. It grows and looks its best in cool-summer regions across USDA Hardiness Zones 2 through 5, according to Michael Dirr of the University of Georgia.
How to care for a Schubert Cherry Tree?
Cover the soil around the trunk of the Schubert chokecherry with a 3- to 4-inch layer of organic mulch. Extend the mulch 2 to 3 feet beyond the farthest reach of branch tips. The mulch decomposes to release nutrients into the soil, deters weeds and keeps the soil cool and moist over the summer.
