How to Grow and Take Care of Citrus

There’s nothing quite like the burst of flavour from homegrown citrus fruit. Whether it’s a fresh lemon squeezed over seafood, a juicy mandarin in your lunchbox, or a bowl of sweet oranges for breakfast, growing your own citrus trees is easier than you might think. In this guide, we’ll show you how to grow citrus, care for them, and avoid common problems so you can enjoy a bountiful harvest for years to come. 

Best Citrus Trees for NZ Gardens 

New Zealand’s temperate climate is ideal for growing citrus. Some of the best citrus trees for NZ gardens include lemon trees, orange trees, mandarins, limes, and grapefruit. If you’re tight on space or renting, don’t worry — there are plenty of citrus varieties for small pots. Dwarf Meyer lemons and mandarins are perfect for growing citrus in pots and can easily thrive on patios and balconies. 

When to Plant Citrus 

If you’re wondering when to plant citrus, the best time is during spring or early autumn. This allows your tree’s roots to settle before facing hot summers or cold winters. 

Best Soil for Citrus 

Citrus trees love a warm, sunny spot with free-draining soil. The best soil for citrus is slightly acidic (pH 5.5–6.5) and rich in organic matter. Before planting, dig in compost and well-rotted manure to give your tree the best start. 

Citrus Tree Planting Tips 

When planting, dig a hole twice the width of your tree’s root ball and about the same depth. Position the tree so the top of the root ball is level with the soil. Water thoroughly after planting. One of the most important citrus tree planting tips is to keep the graft point above the soil line. 

Feeding Citrus Trees 

Feeding citrus trees regularly is essential for healthy growth and good crops. Use a specialist citrus tree fertilizer gardeners recommend, applied in early spring, midsummer, and early autumn. Well-fed trees produce more fruit and stronger growth. 

Citrus Watering Guide 

A reliable citrus watering guide is simple — water deeply and less frequently to encourage strong root systems. In hot, dry periods, water once or twice a week. In winter, reduce watering, especially for growing citrus in pots. 

Citrus Tree Mulching Tips 

To keep moisture in and weeds out, mulch around the base of your citrus trees. Citrus tree mulching tips include using organic mulch like pea straw or bark chips and keeping mulch a few centimeters away from the trunk to prevent rot. 

Pruning Citrus Trees 

Pruning citrus trees encourages better airflow, reduces pests, and shapes the tree. Light pruning after fruiting in late winter or early spring is best. Remove any dead, damaged, or crossing branches. 

Common Citrus Pests and Diseases NZ 

Keep an eye out for common citrus pests like scale insects, aphids, and whitefly. Citrus tree diseases gardeners should watch for include sooty mold, root rot, and citrus borer. Regularly inspect your trees and use organic sprays when needed.
