Mandarin Orange

Citrus reticulata 'Owari Satsuma'

fruit

Owari Satsuma is the cold-hardy Japanese mandarin that handles brief dips into the mid-teens once mature, making it the most reliable citrus for the Gulf South and the West Coast outside frost-free zones. The seedless easy-peel fruit has tender juicy bright-orange flesh with a sweet flavor balanced by subtle floral notes.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Marigolds: Nematode suppression at the root zone
• Lavender: Drought-tolerant partner that attracts pollinators and beneficial insects
• Basil: Aromatic foliage may discourage citrus leafminer and supports pollinators
• Comfrey: Mineral mulch that returns potassium and trace elements

🛡️ Pest & disease prevention

Proactive ways to stop trouble before it starts. Tap a name with an arrow for its full guide

• Citrus leafminer →

  Limit pruning, time horticultural oil sprays to new flushes, and hang yellow sticky cards to monitor adults

• Aphids →

  Avoid heavy nitrogen, encourage ladybugs and lacewings, and blast colonies with water

• Scale →

  Apply dormant oil in late winter to smother overwintering scale

• Sooty mold →

  Treat the underlying aphid or scale infestation; sooty mold lives on insect honeydew and clears once the pests are gone

🌾 Harvest & storage

Owari Satsuma ripens October through December and does not hold well on the tree once mature, so pick promptly. Look for full orange color and a fruit that gives slightly to thumb pressure. Snip with pruners (do not pull, which damages the soft rind). Stored in a cool spot, Satsumas keep for two to four weeks.
