Apples are the nation’s favourite fruit; we grow it more than any other kind. Unlike many other fruits the apple is at home here. Yet despite this, for those who grow apples there is always risk of having a disappointing year.

Weather plays its part and so there may be anguish across different parts of the country but even a fellow gardener down the road may be having some trouble which tells us there are things we can do to ensure a bumper crop of delicious and ripe apples.

Symptoms

The typical signs of a poor harvest may be that you only have a few, or even no apples at all.

Sometimes an apple tree can fall into a biennial harvest cycle, which means it only produces fruit every two or more years. This is typically because the tree has exhausted itself the year prior or isn’t receiving all the essentials.

Equally having a large amount of apples, but all of them being very small and poorly developed defines a thin crop. Surprisingly then, having too many apples as well as too few are signs of a failing tree. These symptoms lead to some different and some similar remedies.

Weather

Before I mention the different issues we do have some control over, it is worth mentioning the one critical factor over which we have less power; the weather.

  • Periods of extended heat and the resulting drought can be particularly catastrophic for young apple trees trying to establish themselves. With underdeveloped leaves and roots they are far more susceptible to losing water and being damaged by hot temperatures.
  • Drought aside, periods of long extended rain throughout the summer will prevent pollinating insects coming out which can be devastating. In 2012 Britain faced the worst apple harvest for several decades with orchards losing up to 70% of their entire expected crop for this very reason.
  • Frost, however, is potentially the most damaging force against fruit everywhere. With the ability to destroy blossoms and fruitlets it can severely diminish a tree’s ability to bear fruit. If the country experiences warm weather in the early spring, instigating blossom, followed by a late and harsh frost a tree may struggle to bear any fruit at all. This is something British wine growers are struggling with this year.
Apples Lost to a Late Frost

To help improve your chance of seeing fruit it is important to make sure your tree is well watered, especially if it has been planted within the last 2 years. You can also use a horticultural fleece if there are late extended cold periods. Importantly it is a good idea to have a range of trees which blossom at different times of year to maximise your chances of pollination. See the ‘Pollination’ section for more details.

Thinning

The Problem

The main cause of an abundance of small, poorly developed apples and biennial harvest cycles is a tree which has exhausted itself in trying to produce a bulk load of apples.

Naturally the tree wants to make as many seeds as possible but this process requires incredible amounts of nitrogen. So if you want an annual supply of fully developed and ripe apples it may be necessary to thin your tree early in the fruiting period.

The tree may try to do this naturally in what is known as the ‘June Drop’ but it doesn’t hurt to give mother nature a helping hand. It may be traumatising to waste so many fruitlets but when it comes to human consumption quality certainly beats quantity.

The Solution

  • First of all rid the tree of any diseased, rotting or malformed fruitlets.
  • After this simply remove the remaining apples until you are left with one apple per 4-6in for dessert (eating) varieties and one apple per 6-9in for cooking varieties.
  • When choosing between apples it is always better to rid those on the underside of branches which may not receive as much light or air.

Pollination

The Problem

Pollination is usually the critical factor in how well your tree fruits. If your tree lacks a pollinating partner or the beneficial pollinating insects, cross pollination may not occur, resulting in a poor crop.

The Solution

  • An apple tree typically needs a pollinating partner within a proximity of around 50ft. This partner must also be an apple tree but of a different variety; very few apple trees are self-pollinating.
  • Apple trees are categorised in pollination groups (1-6) based on when they come into bloom (1 being the earliest in the year). An apple tree such as ‘Red Devil’s Dessert’ (group 3) may pollinate a ‘Gala’ (group 4) however a tree such as ‘Bountiful’ (group 2) may have finished flowering before ‘Lord Derby’ (group 5) comes into bloom.
  • In more rural settings, ensure your apple tree has the right pollinating partners nearby if you are to expect fruit. Ensure there are two different varieties with similar pollination groups. You can even plant a Crab-Apple tree, which makes a fantastic ornamental tree, to act as a pollination partner.
  • Some apple trees such as ‘Bramley’s Seedling’ are triploid trees meaning they require two different pollinating partners.
  • Make your garden attractive to pollinating insects. Lavender, Chamomile and Daffodils are all great plants for getting these welcome visitors into the garden early on in the year while also deterring the pests. See our guide to companion plants for fruit trees for fantastic tips on how to bring beneficial pollinators into your garden!

Pests and Disease

The Problem

Unsurprisingly apples are a prime target for a whole host of pests and diseases. These biological annoyances can be the scourge of otherwise perfect fruit, causing ruin, rot and fruit drop. In particular apples suffer from ‘apple scab’, ‘codling moth’, ‘brown rot’ and ‘apple maggot’, among others.

The Solution for Disease

  • Maintaining sound horticultural practices is the best line of defence against pests and disease. Pruning, weeding and keeping your garden clean of fallen leaves and rotting fruit is a simple but effective way of eliminating all those places which harbour apple-destroying life. Equally cutting the grass around your tree and applying a mulch will further help protect it.
  • Most diseases such as Apple Scab and Brown rot are fungal and infect fruit through rotting material which may have been contaminated from last year. Burn infected leaves and fruit or bury at least 1ft under ground to prevent the spread of spores.
  • Regularly check your fruit for any sign of infection or any wounds. Be vigilant when pruning and always sterilise your pruning equipment when dealing with a diseased tree.
  • As the tree is budding in spring, certain fungicide sprays are available such as a copper based solution. This should be sprayed as the leaves emerge and then again 14 days later; this is, however, mainly preventative.

The Solution for Pests

  • For insects such as Apple Maggot and Codling Moth again you want to destroy any potential hiding spots and prune out any areas of congestion. Hiding spots may include plastic tree guards and so a metal mesh guard is recommended instead.
  • Nontoxic horticultural oils are a good way to kill dormant insects and their eggs which should be applied on the tree during spring. Sticky and pheromone traps can be used and should typically be set in early May before the insects mate.

  • There are several all-purpose bug sprays but these can deter the more beneficial pollinating insects and should only be used when there is a clear infestation.
  • Certain plants, such as chives provide a strong deterrent to pests including deer and rabbits as well as insects yet is attractive to many beneficial pollinating insects. Additionally dill, fennel and nasturtium all provide an organic solution to protect your fruit trees against pests. Again see our Companion Planting post for further details.

Hopefully I have helped to explain why your tree may be fruiting below par and you’ve found a remedy for this frustration.

Gardening, Gardening Year, How To, Liam, Plants, Trees

Many of us are unaware of what a good, well-shaped fruit tree is supposed to look like. We all know that it is supposed to bear fruit but sometimes we neglect that the key to this is pruning.

Whether you have just brought your fruit tree or if you have let nature run its course over the last few years it’s a perfect time to start an annual pruning regiment. A well-shaped fruit tree can support the most fruit and is less susceptible to disease and pest infestation.

Fear not! Pruning is not as daunting as it sounds and with this guide you’ll know how to prune a fruit tree in no time. With just a few hours every year you’ll be sure to expect a bumper crop of your very own.

In this guide we’ll be covering the two main types of fruit tree; the pome (apples, pears, seed bearing fruit) and stone (cherries, apricots, plums) fruit varieties. The central premise for all is the same but there are some slight adjustments in method and timing dependant on the variety.

Pruning a Pome – The Winning Formula

To those that know, gardening is incredibly sentimental. But to yield the greatest crop you have to be clinical and professional. Cutting so many young fruitlets, branches and leaves may feel counter-intuitive but in the long-run your tree will thank you for it, trust me. With that being said you do not want to be reckless. Over-pruning equally leads to a decline in the abundance of fruit.

Pruning serves two main functions; training and maintenance. As the tree is growing you can train it through pruning out undesirable branches and guiding the tree to an evenly-spaced, goblet shape. Once this is done you’ll be left with branches capable of supporting fruit. The objective then is to maintain this shape and keep things tidy.

How to Prune a Fruit Tree Diagram
Step by Step to the Desired Shape

For Young Trees (2-4 yrs)

  • When pruning a Pome fruit tree it is best to carry this out during the winter while the tree is dormant.
  • Always remember to cut at a 45° angle and to wash any pruning equipment in a sterilising solution if you are dealing with anything diseased. This will help prevent the spread of contamination.
  • The priority is to get rid of anything dead, dying or diseased. The goal is to manage the plant’s growth so that energy is directed into establishing the roots and healthy branches.
  • You then want to remove any vertical and acute growing branches. These branches won’t be able to support the weight of fruit and usually end up getting damaged.
  • You also want to prune away any branches that cluster or cross over. When these grow larger they’ll damage one another and help the spread of disease and pests. 
  • This may require you to cut as much as a 1/3 of all your branches if the tree is particularly unkempt.
  • We are looking to train the tree as horizontally as possible. So with the branches you have left you should cut back to an outward facing bud. This will stimulate growth from this bud training the branch outwards.

In the early years pruning is a form of training designed to stimulate growth in branches capable of supplying fruit. Even though by this point the side shoots may be very small it is a good idea to cut them off if they’re growing inward to maintain the desired shape early on.

For Older Trees (5+ yrs)

As the tree gets older however, and especially if you’ve been suffering from poor harvests, the aim is to maintain the shape and branches which can support fruit maximising your yields.

  • After removing anything dead, dying or diseased you then want to pick out any unfavourable branches. These again include any vertical, acute or congested branches. This opens the tree up allowing for air and sunlight to reach it.
  • Additionally if there are any branches growing from below the rootstock these are ‘suckers’ and should be pruned out entirely.

The Perfect Pruning Cut
  • After this, prune back last year’s growth on each of the main branches roughly by about ⅓. Prune back to just above a bud which looks like it will grow outwards in the desired direction.
  • A cautionary note; an apple tree will respond to very heavy pruning by a vigorous regrowth the following year. So if you have a tree which needs some serious renovation it may be worth spacing the work out over a period of 2-3 years.

After this, when you have a neat and well-trained tree, simple annual maintenance should keep a great shape for growing fruit.

Pruning a Stone Fruit Tree

  • Unlike the Pome a stone fruit tree such as a cherry or apricot will prefer being pruned during spring for younger trees and early to mid-summer for established trees. This is to prevent your tree being contaminated with silver leaf or bacterial canker, both of which serious tree diseases.
  • When it comes to pruning a stone fruit tree the method is the same as for the Pome fruit tree and again you want the same result; a goblet-shaped tree with strong, evenly spaced branches growing out horizontally.

  • Pruning in spring and summer may require you to cut out buds and fruitlets. However traumatising this process may seem it is necessary. The key to good pruning is to be as professional as possible; in the long run you and your tree will reap the benefits.

Despite the fact cutting off developing fruit may see wholeheartedly counter-intuitive it must be done and can actually lead to a better crop. Many trees naturally want to produce as many seeds as possible which can lead the tree to exhaust itself. If this happens your tree could fall into a biennial harvest; only producing fruit every two or more years. See the section on ‘thinning’ in our  apple tree troubleshooter (coming soon) for how to do this. 

Pruning is the key to a healthy tree and fruit which develops and ripens beautifully. Hopefully by now you know how to prune a fruit tree. Over time though you may recognise specific trees respond to different kinds of treatment. This is all part of a personal learning experience with your garden.

Bulbs, Cat, Gardening

Amorphophallus titanumOne of the latest additions to our range of plants, trees and bulbs is the amorphophallus konjac which belongs to the araceae family.

It is a unique plant in many ways – its looks are most certainly unique, but really it is known for its rather pungent smell.

We think it’s possibly the stinkiest flower we can grow in the UK and the smell – or perhaps that should be stench – has been compared to cheese, rotting fish, a sweet floral scent, mothballs, and several other equally pleasant smells.

Who would you gift this plant to?
