Growing apricots


Robin Gale-Baker, from Sustainable Macleod, discusses growing apricots. This is one of a series of articles she has written about growing fruit trees (see right hand sidebar). She has also written a number of articles about growing various vegetables, growing various herbs and general growing techniques.

Apricots, with their luscious combination of sweetness and tanginess are, in my opinion, the tastiest fruit in the stonefruit orchard. There’s nothing like waiting for those first tree-ripened apricots, red-blushed on the side facing the sun, in December or January and taking a first bite of their sweet juicy flesh.

Planting and positioning

Plant in winter when the tree is dormant. Choose a well-drained, fertile spot and dig a deep hole. Incorporating some slotted pipe down the side of the hole will make delivering water direct to the roots both easy and efficient later on during hot weather.

Select a tree that can develop four main branches and prune to a vase shape. When you plant, check the width that the tree will grow to and leave ample space all the way around it (including appropriate distance from fences) as this will allow good air circulation and prevent a build-up of humidity resulting in fungal disease. And plant in full sun so that the fruit will ripen!


There is some contention about the best regime for fertilising apricots. Some experts say that autumn is the time to feed apricots and not spring and recommend fertilising after cropping has finished so that the tree and its fruit are nourished for the following spring and summer. They say spring feeding may result in lower crop quality. Others say that apricots should be fertilised in late winter, mid-spring and mid-summer if needed and NOT to fertilise late summer and autumn as this produces sappy growth prior to winter and increases the risk of infection. Both schools agree that a fertiliser high in potassium and phosphorous and low in nitrogen is best for apricots.  Composted chicken manure is ideal along with worm castings and worm juice.  Drinks of seaweed solution during the growing period are also helpful


Water is a must! Apricots need water during hot summers and after cropping so that their buds will develop well the following spring. Water around the tree’s drip line once a week or, as mentioned above, install slotted pipe at planting and water directly to the roots through summer and autumn. Apricots do not like wet or boggy ground so your site must be well drained. They also do not like rain at flowering time, or when the fruit is close to maturity, but there is not a lot we can do about that. I have, however, seen beach or market umbrellas placed over small and medium-sized trees used to good effect during downpours to prevent apricots splitting.

Mulching with pea straw will help retain water, but make sure that it is not close to the trunk in order to prevent development of fungal disease.


First, make sure you clean all pruning equipment with methylated spirits before beginning and after each cut of a diseased limb. Initially, pruning should shorten branches, retaining four main ones that form a vase shape.

For second year pruning, choose two laterals per branch and shorten them to expand the structure of the tree and keep it balanced. This also allows the branches to thicken and strengthen. The time of pruning is critical. It needs to be done in February or March on a warm dry day and preferably in a week that is predicted to be the same. This avoids infection from silver leaf and bacterial canker and other fungal infections entering and taking hold through moist pruning cuts. The quicker that the cut dries the better. In general, begin by pruning dead wood and dried out spurs, any diseased wood (e.g. branches with any dieback on their tips or seeping gum) and any crossed branches, plus thin out the spurs removing old and weak ones. Then stand back and look at the structure and decide what else to prune. This will include long laterals – you want to keep the gnarly spurs close to the trunk and main branches – and any branches cluttering up the centre of the tree. Having an open centre will also prevent fungal infections caused by a lack of air flow resulting in humidity. You may also want to lower the height of the tree for easy and safe picking, and to deter possums and bats that prefer taller trees. When you have finally finished, stand back once again and survey your work. This will alert you to any imbalance in your pruning which you can immediately rectify.

Apricots grow on spurs and these last 2-3 years. After the third year, prune out old spurs to make way for new ones. Flower buds open on one-year old wood, and later as the tree matures, on older spurs. Apricots often fruit heavily one year and not the next but to some extent this can be remedied by reducing the fruit when they are small and green in the ‘heavy’ year. If all the energy goes into the crop one year, it won’t be available for the next. Twist one out of three apricots from the branch to reduce numbers and this will also increase the size of the fruit.


My all-time favourite is Moorpark. Moorpark, with its large juicy, orange fruit was developed in the 1600s in England and is massively popular to this day. It ripens late December to early January. Trevatt, which is yellow with a red blush, is also delicious and ripens in December, in time for Christmas. Both Moorpark and Trevatt come in dwarf forms. Fireball, with its deep orange colour and sweet, traditional apricot taste is a delicious new cultivar. When it gets down to it though, what apricot isn’t delicious and worth having?


These include possums, bats and rats. Rats are hard to deter as they run up the branches taking a bite here and there of all ripe fruit and can destroy a crop overnight. This happened to me one year and what was a fabulous crop one evening, was a tree stripped bare the next morning. I found all the pips under a tub nearby, so was able to count exactly how many apricots had been demolished! Birds, of course, like a tasty nip of ripe fruit and the answer to this is to net securely, taking care not to bend the branches, or to pick the fruit a little before it is fully mature and ripen it indoors in a single layer on trays. Small insects like earwigs and garden weevils can be a nuisance and are responsible for small holes in the fruit. Good hygiene is the best deterrent along with a barrier to prevent them climbing up the trunk and spreading. If you spy harlequin beetles, this is an indication that your tree is not healthy so thank them for letting you know.


The disease that most of us are familiar with is brown rot. This is easily seen as the term accurately describes the large spots of rotting flesh. As the rot develops, whitish grey spores will cover the surface of the apricot. Brown rot is a fungal disease spread by wind and rain. It develops on mummified fruit left on the tree and ground and settles on twigs as well. Remove any mummified fruit or dried flowers, rake up and remove all litter regularly beneath the tree and use a lime sulphur spray at leaf fall and again before bud swell in late winter. Spray all sides of the trunk and branches and agitate the mix every few minutes to stop the copper and slaked lime from separating. You may also need to clear the nozzle.

Apricots also suffer from gummosis (bacterial canker), which appears as gummy swellings on branches where there is a wound to the bark. It occurs when there is splitting in the crutch between trunk and branch and this can be caused by such things as too much weight of fruit on a soft branch or rapid growth in spring. It can also be caused by borers – check for sawdust in the gum or around it – or mechanical damage from mowers or whipper snippers. Or even blunt secateurs. Gummosis needs to be managed – spraying won’t help – so keeping the tree well pruned, using clean secateurs and protecting it from mechanical damage are the best strategies to use. Other less common diseases include silver leaf and verticillium wilt.

Companion planting

A little-known fact is that a fungus that capsicums are prone to can infect apricots so avoid planting capsicums near or beneath apricots. Alliums, especially chives and leeks, are useful for deterring borer insects and basil and tansy repel fruit flies. Tansy also repels ants which can often be seen climbing up apricots searching for sugars. One plant won’t do the trick. As a companion, you need to plant a number right round the tree.

Nutritionally speaking

Apricots are high in Vitamin A – in fact, they are the supreme stone fruit in this regard. They also contain Vitamins B and C and minerals such as calcium, iron and potassium and some protein, so they are a wonderfully nutritious and versatile food. Eaten fresh they are sweet and tangy. They make luscious jams, curds, butters, tart fillings and chutneys on the sweet side. On the savoury menu, they can be paired with chicken and lamb. And dried as fruit leathers or dried apricots they are delicious.

  1. I planted a dwarf apricot (Trevatt, Fireball) two years ago in the southeast corner of my courtyard garden in Geelong. It gets lots of light but perhaps sun is limited to the late afternoon when sun is higher in the sky and reaches my courtyard. The tree has grown to 2 metres, vase shaped, There are no leaves along the branches, only on some tips. Good soil and drainage. Protected by corner position (two fences). I have had a half dozen or so blossoms both years but leaves simply don’t grow. What can I do?

    • Maria, the most likely cause is a watering problem. Apricots hate to be water logged but also need regular deep watering. There is really no rule fits all. Some apricots will need a lot more water than others depending on soil conditions and position. I would advise digging down around the dripline before watering and seeing how deeply the moisture extends. If it is very dry (or very wet), that will be the problem. Apricots generally like to dry out and then receive a deep water. If this is the problem then keep checking until you work out how often to water and how much water the tree needs and this will of course vary during the year. Any rain that is less than 10mm does not count as it will not penetrate the soil.

      The other possibility is that you have an early fruiting variety that puts all its energy into fruiting and only gets leaf after the fruit is mature.

  2. Good morning, the house we have been renting for the past four years has a very large apricot tree which a neighbour used to produce the best apricots but, though it gets covered in blooms, we have never seen any fruit on it. What could be the cause of this please and what can we do for it?

    • Hi Eve,

      This is a tricky problem especially as the apricot used to fruit well. I can only give you a range of reasons and you can see what is applicable. However, the first question I would ask is ‘What has changed since it fruited well?’ Did it fruit well until you took over the property or did it begin to fail for a previous owner? This might lead you to an answer.

      As your tree flowers, lack of pollination is the first thing that comes to mind and this is the most likely reason for any fruit tree not to set fruit. This could include the use of pesticides by someone in your area. Apricots are self-fertilising so do not need another tree to cross pollinate but can do better if there is one close by, so was there another tree that has been removed?

      Other possible reasons are:

      1. Over fertilising with nitrogen fertiliser which produces weak growth. Use organic compost in autumn or spring. There is contention about when to fertilise. The autumn advocates say fertilising in autumn plus a good watering around the tree’s drip line weekly produces better buds in spring; those against say it produces weak, spindly growth and a reduction in fruit.

      2. Lack of phosphorus and potassium. Apricots are heavy feeders of these nutrients.

      3. Biennial cropping. To prevent this, thin fruit each year so that the tree is not exhausted and takes a season off to recover.

      4. Root damage or pest damage of the wood rendering the tree too weak to produce fruit.

      5. Noticing whether the temperature is too hot or too cold at time of blossoming as both can damage flowers and prevent fruiting. (Apricots prefer dry, spring weather). Also notice whether something has been removed from the landscape that sheltered the tree from strong winds which might destroy the blossoms. Frosts can damage the structure of blossoms even though they may look normal.

      6. Lack of or too much water or boggy soil.

      I would be interested to hear what, if anything, works.
