Growing Cumquat in Australia: The Complete Guide
Cumquat is an easy citrus tree to grow, needing full sun with regular, deep watering.
If you're thinking about adding cumquat to the homestead, here's the real detail behind our printable guide — what it actually takes to grow it well in an Australian garden.
Compact and pot-friendly
The smallest of the common citrus, cumquat stays naturally compact and does very well in a large pot — a good option if garden space is limited.
Getting Cumquat Into the Ground
Method — plant with the graft union above soil level, in the ground or a large pot. Soil — well-drained, slightly acidic. Timing — plant in spring.
Ongoing Care
Worth paying attention to:
- Water deeply and regularly, more often if potted.
- Feed with a citrus fertiliser three times a year.
- Mulch around the drip line.
- Prune lightly to shape after harvest.
Common Problems
Keep these points in mind:
- Citrus leaf miner — prune affected tips.
- Gall wasp — prune out before spring.
- Sooty mould — treat the underlying pest.
- Fruit drop — irregular watering, more common in pots.
Picking and Keeping Your Harvest
Signs — full orange colour, fruit is eaten whole, skin and all. Method — cut or twist from the stem. Curing — none needed. Storage — room temperature about a week, or refrigerated longer.
