Growing and harvesting citrus fruit is one of gardening’s simple pleasures - so don't let pests and problems get in your way! We answer common questions about keeping trees healthy.
Despite their reputation for being a little fussy, citrus trees end up in almost every Australian garden eventually. From the trusty lemon tree beside the clothesline to a potted cumquat by the front door, these productive plants have become part of the rhythm of Aussie life.
Over a period of centuries, citrus has been heavily bred and selected, resulting in trees of varying size, shape and fruit colour, including dwarf forms suited to pots, balconies and courtyards.
In addition to its diversity, citrus is a great communicator. The plants will usually tell gardeners exactly what they need through a handful of common signs and symptoms, making it surprisingly easy to diagnose and fix problems before they become serious – and to keep plants healthy, productive and looking their best. Here are a few common citrus conundrums, solved.
Q What’s the easiest citrus to grow?
A Lemons are hard to beat, particularly Meyer lemons. This hybrid citrus is productive, resilient and seems determined to fruit no matter what. Cumquats are another excellent starter citrus because they stay naturally compact and crop reliably.
Q Can citrus handle frost?
A Established trees tolerate light frost, but young trees are much more vulnerable. Covering them on freezing nights can make a huge difference. In colder areas, position trees near a north-facing brick wall in full sun to maximise radiant warmth.
Q Why don’t I have fruit?
A Too much shade or overfeeding with nitrogen can encourage leafy growth instead of flowers. But sometimes the answer is simply patience. Young citrus can take a few years to settle in properly.
