Pruning trees on your property is necessary for the overall health (as well as aesthetics) of the tree. For ficus trees, pruning will help shape the tree (whether it is an indoor or outdoor tree), promote new growth, and get rid of diseased or dead branches.
Wear the work gloves to protect your hands, if desired. For indoor ficus trees, prune lightly around the edges, and get rid of any broken branches or twigs, just to shape the tree. There is more work involved for outdoor ficus trees. Start pruning outdoor ficus by first focusing on the bottom area of the tree. Prune off any branches that are less than 8 inches long on the bottom of the tree.
Examine the middle area of the ficus tree now. Prune any dead, broken or rotting branches that you see. Also, remove any branches next that are growing straight down or upwards, or are overlapping with other branches and resting on them. Removing branches such as these help increase air circulation, and sun exposure.
Keep in mind that you need to make the cuts as clean as possible, and use a spray sealant on the open wounds if you prune off a branch larger than 2 inches thick. Discard the trimmed off branches, or add to your home compost pile.
