Position
Full sun, though tolerant of partial shade. The Satsuma mandarin is cold-hardy tolerating down to around –6 °C.
Soil
Well‑drained, slightly acidic to neutral. Add a bag of acid compost. Avoid heavy clay or waterlogged soils.
Adding half a bag of Volcanic Rock Dust (R25 per bag) and a bag of Superfrass (R25 per bag) will assist in rapid growth.
Watering
Regular watering during fruit development — keep the soil moist but not soggy. Deep watering every 10–14 days when established.
Mulching
Maintain moisture and suppress weeds with organic pine bark mulch. Pine Bark Mulch adds acidity to the soil.
Add a thick layer of pine bark mulch, keeping it about 20 to 30 centimetres away from the tree trunk (any closer may cause excess moisture and damage the trunk). This will retain the moisture in the soil and will prevent weeds from taking over.
Add magnesium (e.g., Epsom salts) if the leaves are yellow.
Fertilising
Apply 1 teaspoon of our slow-release nitrogen-rich berry fertiliser every 4-5 months.
Pruning
Prune in winter (dormant season) to remove dead wood and shape the tree. Trees can be pruned to remain compact for smaller gardens.
Train as an open center (vase shape) for good light penetration and air circulation.
Pests and Diseases
Watch for aphids, scale, and mites. Hose off and try microbial treatments if needed.
Practice good garden hygiene (remove fallen fruit and leaves)
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.
Harvesting
Clip or twist off when entirely orange; pick before rains to avoid spoilage.
