Orange trees can be grown in a home garden if the climate has temperatures that remain above freezing. Growing an orange tree from a seed can be hit and miss, and it can take years for for the tree to get established. For this reason, home gardeners usually purchase orange trees that have already been potted. While orange trees may seem like mysterious, exotic fruit trees, they can be grown if theie needs are met when planted.
Plant in a location that receives full sun and has well drained, slightly sandy soil.
Remove the orange tree from the pot it is in. Gently spread out the roots as much as possible. Measure the root width. Dig a hole that is 1 foot wider than the width, but 2 inches shallower than the container the orange tree was in.
Set the orange tree in a large container of water while the hole is being prepared.
Place the root system into the hole, gently spreading out the roots. Place soil over the roots. When the hole is half full of soil, water the roots and allow it to drain. Fill in with more soil to make up for the loss of soil during the watering. Tap it down over the roots. Add more soil until the hole is full.
Build a water ring with additional soil that is about 2 inches thick and 2 feet wide around the outer edges of the top of the planting hole. Water the tree on the inside of this ring, wetting the soil over top of the roots. Water every three days for the first two weeks after planting. After two weeks, water once weekly after two weeks.
