Find a sunny location for your new tree sapling so that it will get plenty of sunshine. Plant several different varieties to ensure good pollination, which will ensure a healthy and plentiful harvest. When planting, dig a hole approximately 18 inches deep and at least 24 inches wide, or as big as the root ball needs with room to give.
Make sure your fruit trees are in healthy soil. The type of soil you need depends on the type of trees you are growing. Citrus trees like sandy, loamy soils. Apples, pears and plums can grow in almost any type of soil, but most do not do extremely well in heavy soils, such as clay. Mix your soil with sand and other light soils, such as vermiculite or peat moss if you have a clay type of soil.
Prune your trees regularly to weed out dead wood and stimulate growth. Pruning will ensure that your plant will continue to grow, spurring new growth and allowing your trees to continue to provide fruit. The best times to prune your trees are between the months of January and March, before the new growing season begins.
Fertilize your fruit trees to ensure success, treating your trees with a healthy balance of nutrients that they might not otherwise receive from the soil. When planting a new tree, scratch a trench 1 inch deep in a circle 1 foot from the tree, then place the fertilizer in the trench. Fertilize your trees in later years with approximately 1 lb. of fertilizer just before your trees start to bud. Placing mulch around fruit trees inhibits weed growth. Stop fertilizing late in the fall so that your fruit tree will stop its growth to ensure it will withstand the winter cold.
Water your newly planted fruit tree during the growing season, especially in dry seasons or droughts. Water your fruit trees at least every 2 weeks, saturating the ground.
