The upright branches can be headed back to encourage more side branches for developing a less leggy, fuller tree. More bushy selections, producing numerous branches and forming thick growth, can be thinned to promote heavier yields. Early fall, after the plants have finished fruiting, is a satisfactory time to prune. Pruning should not extend into late fall since tender regrowth may suffer cold injury nor should it be done just previous to the new spring growth since this will reduce yields. The most serious pest of the Barbados cherry is the root-knot nematode which weakens the plant, causing it to drop leaves and display symptoms of malnutrition.
Severe infestations inhibit growth and fruit production.
This nematode is a more serious problem in sandy soils than in the alkaline, rockland soils of Dade County. It is not a problem in marl or clay soils. Preventive measures include use of sterilized soil in propagation, fumigation of the planting site and heavy mulching around the tree. Frequently, the fruit is attacked by plant bugs which sting the fruit, giving it a dimpled appearance. This may result in off flavors and reduced fruit size.
