Fruit trees produce a huge variation of fruit that fall into different categories. Some fruit tree varieties, such as citrus, grow best in spring, summer and early fall while others thrive in late winter or early spring. The soil requirements vary greatly depending on the tree, but most fruit trees do well in nutrient-rich, well-drained soils and full sunshine. Fruit trees prefer soil with a pH in the 5.6 to 7.0 range.
Lemon trees grow well in sunny states such as Arizona, California and Florida. However, lemon trees can produce in other states during the warmer spring and summer months. Lemon trees can tolerate less fertile soil because they have adapted to several types of rocky soils in dry states, but lemon trees can grow even better if you take the time to prepare the soil before planting. Dig your hole about 3 feet deep and add compost, fertilizer or other organic material to the ground. Water your lemon tree two to three times per week. Choose between varieties such as Armstrong, Eureka and Monachello.
Avocado fruit trees grow well in warmer states such as Florida, California and New Mexico. Fully mature avocado trees produce fruit all year long. These trees have adapted to several types of soil, including sandy, red-clay or limestone. Water your avocado tree several times per week and pick the fruit when the thick shells are firm and light green. The fruit will continue to ripen after being picked from the tree. Choose from varieties such as Susan, Hass and Lula. Store your avocados in a cool, dry place.
Apple trees grow well throughout most of the United States. Most types of apple trees are planted in the spring or summer months. Apple trees will begin bearing fruit within the first year after planting, but the fruit is typically small and immature until the tree is 3 years old. The University of Illinois warns against overfertilizing fruit trees, especially apple trees, because excess vegetative growth around the tree can impair fruit production. Choose from varieties such as Prima, Ginger Gold and Rome.
