No it’s required to Fertilize a sapling when it is planted, first root stimulator has to be given which will help the tree to grown better. Once the tree attains its maturity then it has to be fertilized so that it flowers well and gives better yield.

The best time to fertilize is at the end of summer season when there is lesser shrubs in the farm, else all the shrubs will pick up the fertilizer and the tree will not get enough as intended.

It depends on the type of plants, Fruitial and Timber plants are mainly planted during monsoon season during which less maintenance effort is required for the saplings to grown. Flowering and Ornamental plants which are grown at garden can be planted throughout the year.
