Fruit trees of all types are relatively easy to grow if you want your own healthful, succulent fruit. Some fruit trees grow larger than others. Grapefruit trees typically grow larger than the other varieties of citrus. Mangos, a tropical fruit, can become huge; they also provide shade where you can sit and relax.
If a fruit tree has the correct growing conditions, its chances of growing into a large tree are increased. The type of soil and pH are important factors in the success of any plant. Test your soil with an inexpensive kit from a garden supply store. If you want to grow a huge grapefruit tree, you'll need well-drained acidic soil, with a pH of 6.0 or lower. If you live in an area that often gets hard freezes or snow, the subtropical grapefruit will not be able to survive the winter.
Space and Sun
All trees need enough space to spread their branches. If other trees confine or shade a fruit tree, it will not be able to grow to its potential size. Other trees, even buildings, can cast shade on your fruit tree, which will deny it the light it needs. Make certain before you plant that the area where you want to grow your fruit tree is large enough and that it receives sufficient sunlight during most of the day.
Give it the correct amount of fertilizer at the recommended time intervals, depending on the type of tree you are growing. Citrus trees need fertilizer three times each year: in late winter, mid-spring and mid-summer. If you fertilize any plant too late in the season, an early frost can easily damage the tender new growth that fertilizer causes.
Fruit trees benefit from a bit of pruning at least every other year during their dormant season in winter. Limit your pruning to dead, broken and diseased branches. Some types of fruit trees require special pruning to help them produce the maximum amount of fruit, so research your tree before you prune it. It's important for light to reach the central portion of a fruit tree, so keep this in mind when you prune any fruit tree.
