Growth and Management
Annual height growth of sprouts from cut stems varies from 1 to 3 m/year. Up to 60 sprouts are produced per stem. Maximum height at 20 years is about 9 m. At higher elevations, shrubs reach 4 to 5 m in 15 years, after which growth slows until a maximum height of 10 m is reached. Fruits should be collected by hand or with pruning poles as soon as they turn from green to yellow. The capsules are air-dried until opening. Generally, the seeds should be sown as soon as possible because they remain viable for only a few days. Seed can be stored in sealed containers under refrigeration for four to six weeks, but germination begins to drop rapidly after 10 days. Seeds are broadcast on well-prepared beds that are kept continually moist until germination and seedling emergence. Light is required for successful germination. Recommended spacing using rooted cuttings for erosion control is 1.8 m by 1.8 m; for unrooted whips or shorter cuttings, 0.6 m. Rooted cuttings can be grown to 3 m tall in containers. Cuttings should be 45 to 60 cm long, and whips (not recommended) should be 1.2 m long.

Famous quotes containing the words growth and, growth and/or management:
“This [new] period of parenting is an intense one. Never will we know such responsibility, such productive and hard work, such potential for isolation in the caretaking role and such intimacy and close involvement in the growth and development of another human being.”
—Joan Sheingold Ditzion and Dennie Palmer (20th century)
“Every child has an inner timetable for growth—a pattern unique to him. . . . Growth is not steady, forward, upward progression. It is instead a switchback trail; three steps forward, two back, one around the bushes, and a few simply standing, before another forward leap.”
—Dorothy Corkville Briggs (20th century)
“The Management Area of Cherokee
National Forest, interested in fish,
Has mapped Tellico and Bald Rivers
And North River, with the tributaries
Brookshire Branch and Sugar Cove Creed:
A fishy map for facile fishery....”
