How to Grow Fruit Trees

Once growing fruit trees at home was very common. Nowadays with gardens being smaller, the availability of wonderful new generation fruit trees has seen a resurgence in growing healthy home-grown goodness in the places and spaces we call home. There are dwarf forms/varieties of most fruits which don’t take a lot of space. These can be grown in small gardens, in pots or containers and espaliered, (trained to grow flat) against a fence as space savers. This allows a collection of many fruits spread through the season.

When choosing fruit trees, consider varieties best suited to your area as they love a warm and sunny spot in the garden. Kaipara Coast Plant Centre specialises in varieties that grow well in the Auckland region. 

Pip fruit such as apples and pears have always been the most popular fruit because of their universal appeal, they are easy to eat, and ripen over a long season. They are vitamin rich, great tasting, and are relatively easy to grow. They are also very attractive trees with their spring blossom. If you are not sure which variety you like, take a note of the varieties in your fruit store you like. But, don’t be afraid to try something you can’t get in the supermarket, such as Apple Egremont Russet or Apple Golden Delicious, or some of the disease resistant newer selections. 

Stone fruit such as cherries, apricots, peaches, nectarines and plums, are also favourites with great variety of taste. Stone fruit does not keep as long as pip fruit, but with the many varieties giving a spread of maturity, it is possible to plan a spread of harvest dates. 

When designing an orchard, We always try to have at least one variety fruiting each month of the year. 

Dwarf varieties are available for smaller gardens, however they generally need better soil than their taller counterparts. We try to keep all our fruit trees trimmed to around 2m tall and wide to make picking and pruning easier, which also means you are not limited to using dwarf varieties in tight spots. 

How to Care

Planting

Choose a warm sunny position, sheltered from strong winds. Pip and stone fruit trees will grow in most soils, but in clay soils, raise plantings and add at least 10litres  of Kaipara Coast Planting Mix per hole, and mix this into the existing soil. This is particularly important when planting in Aucklands clay soils. 

Winter is traditionally the time to plant fruit trees, however Kaipara Coast Plant Centre has potted plants that can be purchased throughout the year.  Just remember to water your trees at least once a week if planting in the drier months.

Mulching

This is a highly recommended practice as it suppresses weeds and conserves moisture in the soil. A layer of mulch, compost or similar laid on the surface in October will prevent moisture loss and greatly benefit the trees.

Feeding and Watering

Fruit trees benefit from an annual dressing of lime or gypsum in July/August, followed by an application of a suitable Kaipara Coast Citrus and Fruit Tree Fertiliser in September.

Many fruit trees can withstand considerable dry periods, but watering will greatly improve the result. Ensure soil does not dry out after planting, but be careful not to overwater (only if a dry spell follows planting – do not overwater as root rot could result).

Over the Spring to Summer period, water at least once a week to ensure plant does not dry out while establishing in its first year. Also stake the tree with at least 2 x  1.2m stakes, so the spring winds don’t rock the tree in the soil and damage the newly forming roots. 

Pests and Diseases

There are a number of pests and diseases that attack fruit trees. If particular pests and diseases are very prevalent in your area it may pay to choose different fruits that are not affected.

Apples, pears and quinces are attacked by codling moth, aphids, mites, black spot and powdery mildew. Some new varieties are black spot tolerant.

Stone fruits (peaches, plums, nectarines and apricots), are attacked by aphids, leaf curl, brown rot, shot hole and rust.

While these pest and diseases sound serious, we find in our own orchard, a careful prune every year, and most diseases are minimised with a winter prune, reducing the need to use toxic sprays. 

There are natural organic sprays that are effective against most pests, or make the decision to concentrate on the soil health and pruning any problem branches off the tree rather than using toxic sprays. 

Pruning

Pruning is divided into two stages.

1. Pruning to shape in the young stages. When planting, select 3 or 4 strong branches and reduce by 2/3 to outwards facing bud. Remove all other growth

2. Pruning for continuous fruiting and maintaining shape of established trees. Pruning to shape is dependent on the variety and to some extent the shape you want.

Basically there are three shapes:

Vase shape – The traditional open centre with 3 to 4 main leaders for framework.

Central leader or pyramid – A more modern method as it takes less space and trees can be kept narrow. Ballerina apples are very suited to this method.

Espalier – An ideal method of training and pruning where space is limited.

Helpful Tips

Focus on pruning to the shape you want.

Always remember that the strongest new growth will come from the first bud below where the pruning cut is made. In general prune to regulate growth, allow light in, encourage flowers and fruit.

Generally, prune in Winter.

In years 1 and 2 after planting prune hard to make a sturdy framework and shape the tree.

Pruning for continuous fruiting is important once the tree has established. This is relatively easy once you know where the fruit will form.

Apples, pears, quinces, plums, and apricots fruit on the same spurs for many years. 

Understanding where the flower buds are and what they look makes pruning a lot easier. 

Kaipara Coast Plant Centre runs annual Fruit tree pruning workshops – to book, go to our workshops page. 

Apples, Pears and quinces fruit on spurs and 2 year old + laterals. Allow lateral branches to develop uncut until buds form, then trim back about 2/3 each year. Thin out some if tree becomes overcrowded.

Apricot

Also bear on laterals and spurs. Treat the same as apples.

Plums

Bear fruit on 1 and 2 year old laterals. Require little pruning. Thin and trim back as required to maintain tree at reasonable size.

Cherries

Fruit on spurs on 2 year old wood. Require little pruning, apart from trimming and thinning. Prune in Autumn to encourage new growth but don’t cut out all previous year’s growth.

Peaches and Nectarines

Peaches and nectarines fruit on one year old wood. That is, the wood grown last year will carry fruit this year. When pruning, do not cut this wood out, but shorten it only and/or remove only some of it.

pollinators

Many plums, and some cherries and apricots require another variety to be grown nearby to ensure pollination. Check with your garden centre for the best pollinator varieties.
