Soil Preference for the Valencia Orange Tree:
It is no longer a recommended practice to amend the soil in the planting hole on Citrus trees in good soil according to the University of Florida’s Institute of Food and Agricultural Sciences. However, probably due to the simple fact that old habits die hard, one UFIFAS citrus publication cautions, if you are going to amend your soil be sure to use a 50-50 ratio. In other words, use equal parts soil amendment and native soil (that is the soil you dug out of the hole before placing the tree in it), and mix the amended soil together with the native soil before backfilling the hole around the tree.
Size of the Valencia Orange Tree When Mature:
The mature size on a Valencia orange tree is 20-25 ft tall and 15 ft wide.
Pruning and Growth Habits of Valencia Orange Trees for the Northeast Florida Landscape:
Pruning is important on young Valencia orange trees to help them develop a branching structure that will hold under the weight of the fruits.
– Remove suckers that sprout up from the trunk, or to remove dead wood that can cause problems when left on the tree.
– When purchasing trees from an S & J Nursery container less than a 30 gallon pot size, pruning may be needed to shape the young trees into a desirable framework, and light pruning each year to develop the citrus tree`s rounded or mushroom shaped canopy.
-As the tree matures it should be shaped by selecting 3 – 5 main branches, well spaced along the trunk for fruiting production. Remove branches with narrow angles, and sub branches that are crossing or rubbing on other branches.Planting and Mulching Tips For Valencia Orange Trees in the Jacksonville | St. Augustine area landscape:
NOTE: THIS IS IMPORTANT
-Be sure to plant into well draining soils, and keep the soil level of the dirt in the container above the soil level of the ground by 1-2 inches when you are finished planting. The soil that your tree was growing in should be slightly higher or level with the ground.
– Never bury the top of the root system ( the dirt in the pot that the tree was growing in). The soil in the top of the pot should be exposed to the air after planting, not buried by soil in any way.
Caution: Do not build berms around Citrus to hold water, as is recommended for pretty much all other trees. Leave a 12 inch diameter area around Citrus tree trunks with no mulch, do not put mulch up to the trunk of the tree,as on Citrus trees, root rot can develop quickly, and good drainage is essential to a healthy tree.
Remove the grass and weeds growing under the foliage of any Citrus tree in Northeast Florida about a foot beyond where the foliage stops. Don’t allow grass and weeds to regrow under your Florida Citrus.
When planting in areas with a high water table, consider planting your Citrus into a raised berm a few feet high and 6or more ft wide. This will keep your Citrus roots up out of the water soaked ground during periods of heavy rain.
Wow, that was a lot of don`ts! Here’s one last one. Don’t worry, it really isn’t as hard as it seems, once you get them going, Citrus trees just keep on growing!
Keeping your Valencia Tree Free from Pests and Diseases:
When it comes to gardening, an ounce of prevention is worth a pound of cure. That is to say that, paying attention to proper planting, watering and fertilizing practices for your citrus tree is the best way to keep it healthy and growing well.
Water Requirements of the Valencia Orange in the Jacksonville and St. Augustine area Landscape:
Newly planted citrus trees require watering every other day for the first month and twice a week for the first few months, or in sandy soils when the top two inches of soil is dry to the touch. Take care to make sure that newly planted citrus trees receive water at least once a week for the first 2 years after being planted, skipping watering altogether once the local rain season is here.
Mature citrus trees need little to no supplemental irrigation and are more often damaged by over watering than under watering.
When citrus trees need supplemental irrigation, make sure to irrigate the soil only and not the trunk or foliage, this is best done by hand with a hose.
Fertilizing Your Valencia Orange Tree for Northeast Florida, Jacksonville and St. Augustine area Gardens:
Citrus trees tend to be a bit demanding on the fertilizing side of the equation.
A good quality fertilizer specifically formulated for citrus trees should be used. Fertilize in spring, again in summer, and skip the fall application in Northeast Florida, and then again in January. Spread your fertilizer out into the circle of non grass area under the Canopy of your citrus tree.
Harvesting your Fresh Valencia Orange Tree Fruits:
Valencia can be left on the tree till ready to use and harvesting can be done from February to June or July.
