Cherry trees are a great choice for the home garden or edible landscape. The trees can double as ornamentals and burst into bloom in the spring and produce nutritious fruit in the summer. Cherry trees grow best in well-drained soil and in full sun. When choosing cherry trees to buy online, find cherry trees that will grow in your hardiness zone. Next, consider your site. Standard cherry tree varieties require more space than dwarf cherry trees. Also, consider whether you prefer sweet cherries or sour cherries (sometimes called pie cherries). Finally, keep in mind that some cherry trees are self-pollinating while other cherry trees need another cherry tree for pollination.
