Prune management

Can be grown as trees but In most yards are best pruned hard to make larger-leaved, more manageable shrubs. 

These vigorous shrubs need pruning baek to a stubby framework eaeh spring to keep them shapely and manageable. 

The area of clove cultivation in Zanzibar and Pemba for the year 1919 was estimated at 52,000 acres, with nearly 5,000,000 trees. The large plantations are held by Arabs, a few by Indians. The yield from each tree varies, especially good crops recurring every three to five years. The average yield per annum from a plantation of 3,000 sixty-year-old trees, owned and managed by Europeans, is 8 lb. per tree, which could be increased by judicious pruning. 

Leadership in short rotation forestry lies in the sub-tropics. Table 5.6 represents a typical regime for Firms taeda in Brazil, i.e. all trees are pruned in the first lift and potential final erop trees only in the second lift. Improved genetics and management have raised average productivity of pine plantations from 18 to 23 to 33 m /ha/yr in the sueeessive deeades, in the 1970s, 80s and 90s respectively. Whether eorewood quality issues have been addressed remains to be seen. 

It would be hard to overstate the importanee of South America and Brazil in particular. By 2010 South America is projected to aeeount for 55% of the world s supply of euealypt plantation roundwood, followed by Asia with 20%. Donnelly et al. (2003) estimate that euealypt sawlogs from plantations will increase to 10.6 million m by 2015, with a total pruned log supply of 1.4 million m. Intensively managed silvieultural systems for euealypts are in their infaney. 

Treatment of prune belly syndrome is primarily conservative, and surgical management is seldom required. When obstruction is absent, the goal of treatment is the prevention of urinary tract infection.
