It can take anywhere from three to eight years for an apple to grow once a tree is planted. There are many factors involved with estimating the amount of time it takes for an apple to grow on a tree, such as proper soil care and climate.
There are a lot of things to consider when planting an apple tree. Planting a tree from a seedling takes more time to produce apples than planting a tree as a sapling, but neither of these has a faster growing rate. The growing rate depends on how well the tree is taken care of.
