How to grow Oranges

Want to grow your own Orange fruit? Here's all you need to know about planting and growing an Orange tree!

Orange trees require warm, moist soil, enriched with plenty of compost. 

Like most fruit trees, Oranges require deep, well draining soil. They will not tolerate waterlogged soil and will develop root rot as a result. Avoid planting in heavy clay unless the soil has been amended. Heavy soils can be improved by incorporating gypsum, organic matter and by mounding the soil before planting to improve drainage. 

Plant Orange trees in a full sun position. 

No. Orange trees are not frost tolerant and will require protection from frost. 

Plant Orange trees roughly 5m apart.  

Autumn or early spring is the best time to transplant Orange trees.

Dig a hole 2-3 times the width of the root ball. The hole should allow the plant to sit at the same level in the soil as it was previously. Fill the hole with soil ensuring the crown of the plant, where roots and stem meet, is level with the soil surface. 

Plant out in the early morning or evening and/or on an overcast day. Avoid planting at peak sun times or on windy days, this will allow your plants to settle in comfortably and protect them from windburn and sunburn.  

Orange trees are heavy feeders. Apply a well-balanced organic citrus food throughout the growing season. Spread the fertiliser evenly around the tree, up to one meter beyond the canopy and water it in well.

Top-dress the soil around the tree with well-rotted organic matter in spring. Add a 2-3 inch layer of mulch around the tree up to the drip line to retain moisture (be careful not to pile mulch against the tree trunk as this may lead to trunk rot and disease). 

Grafted Orange trees start to produce crops after two-three years. Harvest when the fruit is fully ripe and completely orange in colour.   

Pests that affect Orange trees include: Citrus Leaf Miner, Asian Citrus Psyllid, Swallowtail Butterfly, Light Brown Apple Moth, Lemon Bud Moth, Weevils, Fruit Fly, Thrips, Scale, Aphids, Mealybugs, Whitefly, Ants, Crusader Bugs, Mites, Thrips, Citrus Gall Wasp, Spined Citrus Bugs, Nematodes, Snails, Slugs, Ants, Stink Bugs.  

Diseases that affect Orange trees include: Anthracnose,  Armillaria Root Rot, Black Root Rot, Blast, Brown Rot, Stubborn Disease, Sooty Mold, Melanose Fungus, Greasy Spot, Citrus Scab, Citrus Canker, Botrytis Fungus, Phytophthora Fungus, Huanglongbing (Citrus Greening), Tristeza Virus. 

After harvesting your fruit, pruning is required to remove dead and diseased wood as well as wood affected by pests. Only remove up to 20% of the canopy, starting with the longest growth, anymore and you will sacrifice next seasons crop.
