Fruit trees need to be fertilised twice a year, in spring and autumn.

In general, you should use a low-nitrogen fertiliser for fruit trees to ensure good quality soil. Nitrogen is good for foliage growth, but too much can lead to less fruit production. You should also avoid using high-phosphorus fertilisers, as this can encourage root growth at the expense of fruit production.

What is the best fertiliser to use for fruit trees?

The best fertiliser to use for fruit trees and citrus trees is a low-nitrogen fertiliser. Nitrogen encourages foliage growth, but high nitrogen levels can result in less fruit production and poor soil PH. You should also avoid using high-phosphorus fertilisers, as this can encourage root growth at the expense of fruit production. If you're unsure about which fertiliser will best nurture baby fruits and the tree's nutritional needs, ask your local nursery or garden centre for advice on what works for young trees and when to add fertiliser.

Is it better to grow fruit trees from seed or from cuttings?

It's generally better to grow fruit trees such as apples and pears from cuttings, as this will produce a tree that is true to the parent. Growing fruit trees from seed can result in a tree that is different from the parent, as the seed may have been pollinated by a different tree. If you want to grow a fruit tree from seed, it's best to get the seed from a reputable source, such as a nursery or garden centre.

What is the best time of year to plant fruit trees?

Planting in the spring gives the tree a chance to establish itself before the hot summer weather while planting in autumn means that the tree won't be put under stress by the cold winter weather. If you live in an area with a Mediterranean climate, you can plant fruit trees at any time of year.

What is the best way to water fruit trees?

Fruit trees require deep watering about once a week to keep the soil moisture ideal. Watering deeply encourages the roots to grow down into the soil, which makes the tree more drought-resistant. A soaker hose or irrigation system will deliver water directly to the roots of the tree, without wetting the leaves or fruits. If you're using a sprinkler, make sure that it's on for long enough to soak the entire root zone of the tree.

How often should I prune my fruit tree?
