The orange grove is a group of three or more orange trees that are grown specifically for fruit production. These fruit trees still provide the same showy visual impact as single trees, with their fragrant white flowers and dark-green foliage. However, the trees are cared for with the expectation of high fruit production at the end of harvest.
Plant the orange trees in deep, well-drained locations with sandy, water-retentive loams. Dig a hole for each orange tree that is equivalent to the width and depth of the root ball. Plant the trees about 15 to 20 feet apart. Space each row of orange trees about 10 to 15 feet apart, depending on the available space.
Irrigate the orange grove regularly throughout the growing season from bud break through harvest. Provide the grove with approximately 1 to 1 1/2 inches of water each week. Adjust the levels for periods of drought and rain. Cease irrigation after the final harvest to prevent the production of new growth until the next growing season.
Feed the orange tree about four weeks after the buds begin to break. Select a well-balanced, slow-release fertilizer, such as a 6-6-6, 8-8-8 or 10-10-10 combination. Distribute the fertilizer evenly under the canopy of the tree. Keep the fertilizer at least 1 foot away from the trunk of the tree. Water the fertilizer thoroughly into the soil. Feed the orange grove approximately every six weeks throughout the growing season until the final harvest.
Prune the trees of the orange grove to maintain vigorous growth. Remove any rapidly growing water sprouts with sharp, sterile pruning shears. Cut any dead, dying or wilted branches from the tree as they appear. Allow each tree to develop a natural framework.
Keep the orange grove free of debris and weed invasions. Pull any developing weeds from the area by hand to ensure that the entire root system is removed from below the surface. Keep mulch at least 1 foot from the base of the tree.
Harvest the orange grove as the fruit reaches its full size and color, as determined by the specific species that is being cultivated. Harvest the oranges daily until all the oranges have been removed from the trees.
