Citrus growing tips for small spaces

These are my favourites for growing in pots – remember, though, the size of the pot will determine the overall size of the plant: the larger the pot, the larger the plant will grow.

Cumquats

These are a popular, compact citrus, originating from Asia. I’ve seen more gardeners grow cumquats in pots than in the ground. The fruit looks like a mini mandarin, and can be eaten whole. Most modern-day cumquats have sweet skins that balance the tart flesh. They are a naturally dwarfing citrus but are increasingly available grafted on dwarf rootstock too. Two of the best are ‘Nagami ‘(oval in shape) or ‘Marumi’ (round in shape).

Lemons and limes

Both of these thrive in pots, and ripened fruit hold well on the tree and can be picked as and when you need them. Look for dwarf lemons ‘Eureka’, ‘Lisbon’, ‘Meyer’, ‘Lemonicious’ and limes like dwarf ‘Tahitian’ and ‘Courtyard’. For even better usage of small spaces, look for double grafted lemon/Tahitian lime or Tahitian lime/makrut lime trees.

Mandarins

These provide abundant fruit, which is handy for lunchboxes and snacks. Look for dwarf ‘Emperor’, ‘Honey Murcott’, ‘Daisy’ and ‘Japanese Seedless’. Cultivars with smaller fruits are especially good for pots, for example, ‘Imperial’ or ‘Sugar Bubba’.

Native citrus

There are now some lovely dwarf forms of some of our native citruses, which are easy and attractive to grow. These include finger lime ‘D’Emerald’ and ‘Rainforest Pearl’ and Desert limes.

Yuzu

A delightful Japanese citrus that tastes like a cross between lemon, grapefruit and mandarin, with floral notes. Yuzus are cultivated for their juice (and zest) and are sought after in the restaurant world. They are hard to find fresh but easy to grow at home.
