A local tree care expert can advise a you about the variety of orange tree that thrives in your location. Below is general information about the types of orange trees.
There are two kinds of cultivars: early season and late season.
The early season cultivars are the best type for areas where infrequent freezes occur such as the Gulf states and northern Florida. They bear fruit prior to December. Late season cultivars bear fruit after December through March.
Washington navel, Ambersweet, and Hamlin all do well in the early season while Valencia does well in the late season.
The Valencia orange is considered a late season cultivar because it is a summer fruit. Normally, oranges are a winter fruit.
Orange Tree Care
Orange trees need a temperature range of 50 to 100 degrees when the trees are growing. Keeping them in a hothouse is helpful to provide protection to young trees. Orange trees need a sunny spot. The soil should not hold water. If it rains infrequently, water once per week. Mulch is good for the tree. Fertilizer should be applied only four or five times while the tree is growing. Alkaline soil is bad for orange trees.
Orange Dwarf Tree
The orange dwarf tree is a house tree. A two-year old tree will produce between 4 and 6 oranges. An older dwarf will produce more fruit. The oranges are 2 inches in diameter.
Requirements for Growing
The orange dwarf tree is easy to grow but they need a humid habitat and direct sunlight.
Orange dwarf trees need at least 4 hours of direct sunlight each day at a south window. If it doesn't get adequate light it won't bloom. The leaves will yellow when the pH is too high.
Usually, a container plant will require more water than one planted in the ground. But if you place it in a larger container it will need less watering. If it is planted in fast-draining soil, water it less. A heavy soil drains slower than a lighter soil. A lot of wind will dry a container plant out. In the early spring water two or three times weekly and during the summer season, you may need to water each day.
