Position
Plant your dwarf navel orange tree in a spot that enjoys full sun and adequate protection from the wind. In order to allow the tree to grow unhindered, plant it 2.5 to 3.5 metres apart from another tree.
Size
Dwarf orange trees will reach a height of 1.5-2.5 metres. However, these trees can also be grown in a pot (55 litres at least). Orange trees do not like their roots to be disturbed. So, don’t plant other trees, bushes, or flowers too close to them.
Soil Type
Orange trees need healthy well-drained soil. Add compost to the hole that you dig for your tree so that it is in prime condition to nourish the roots. If you opt for a pot, use quality potting soil & acid compost and a pot with drainage.
Mulching
Whether your tree is young or well-established, it will benefit from 2 to 5 centimetres of pine bark mulch in the form of green pine needles, leaves or straw. This mulch protects the roots from UV damage and drying out, retains moisture, and maintains an optimal pH.
Watering
Orange trees need to be well-watered regularly; those in pots even more so. Generally, your orange tree should get 2.5 to 4 litres of water weekly.
Fertilising
Give your orange trees the best chance by fertilising them well. Apply slow-release citrus fertilizer during the harvest season and repeat after the fruiting period. Utilising our slow-release fertiliser is a must for citrus; even though it is called berry fertiliser it is for all plants/trees.
Pruning
Your orange tree will only need pruning to remove dead or diseased limbs or those too close to the ground (around 30 centimetres or less).
Harvesting
These fruits will ripen from spring to summer and usually continue to bear fruit for decades. The orange should be reasonably easy to pluck from the tree if you gently twist it from the branch.
Pests & Disease
Aphids, citrus psylla, red scale, citrus greening. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM Control ) will assist in either prevention or after the fact. If you already have aphids or mites, wash the tree with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (if overwatered) and fungal infections during wet periods.
