Position
Full sun, or at least 6 hours of sunshine a day, and space at least 3-5 m from other trees.
Size
Citrus trees typically grow to a height of 3 – 5 metres.
Soil
Slightly acidic, loamy soil is ideal. Dig a hole at least 50cm and 50 cm deep. Mix a bag of Acid compost into your soil before planting the tree.
Mulching
Pine bark mulch is ideal as it adds a small amount of acid to the soil and keeps the roots warm in winter and cool in summer. It also helps to keep weeds at bay. Place a thick layer of mulch about 5 cm from the stem of the tree.
Fertiliser
Citrus trees require a fertiliser high in nitrogen, which should be added from winter to spring. Use a slow-release, nitrogen-rich fertiliser, such as our berry/all plant fertiliser. Apply 1 teaspoon every 4-5 months. Move the soil about 2cm deep and spread 1 teaspoon of fertiliser, then replace the soil and add new mulch.
Pests and Diseases
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 strong hose, then, when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (caused by overwatering) and fungal infections during wet periods.
Pruning
A good time to prune your tree is when it stops fruiting. Remove branches in the middle of the tree to thin it out, as this will help control pests and diseases. Prune the tree to your desired height and shape to enable easier harvesting.
During the year, cut away branches that cross over one another and remove any tangled leaves, twigs, and branches. This will encourage vertical growth.
Harvesting
Fruit will be ripe and ready to harvest from May to November under ideal conditions.
