Healthy trees are much more capable of fighting off disease and infection so maintaining healthy trees is the best prevention. Mulching, weeding and watering young trees can prevent them becoming stressed, which is when they are most vulnerable to disease.

Creating healthy conditions within mature trees can be achieved by thinning the branches to allow airflow and light around the canopy. If you are planting a new orchard, or gapping up an existing one, remember that trees should be roughly 10m apart. This allows each tree enough space to not compete with the others, but also increases airflow around trees reducing overall disease vulnerability as well as reducing the opportunity for disease to spread amongst the trees.

Prune your trees in good weather. For winter pruning this means avoiding wet and frosty weather. Stone fruit should only be pruned in the summer to avoid silverleaf fungus, the spores of which are prevalent in the winter, but again it is good to avoid pruning during times of rain.

Water can carry disease from tree to tree, so it is preferable not to create any wounds in healthy wood when it is wet. Symptoms, causes and methods of control for popular fruit tree diseases are given below. Whilst still perfectly edible if peeled, the fruit infected with scab develops scabby, corky patches and often cracks which makes the fruit less appetising in appearance and useless for storage. The disease has a less pronounced effect on the rest of the tree, but can be seen as dark round dusty blotches on the leaves.

Leaves with heavy infection may shrivel and fall prematurely. Scab is a fungal disease of apple and pear trees that affects the whole tree but are most easily seen on the leaves and fruits.

Scab can overwinter in several ways, but the most important is overwintering on fruit tree leaves on the orchard floor.

In cold winters this is likely to be the only place that scab overwinters. Come spring, spores from overwintered leaves on the orchard floor become wet and then are spread by the wind. A wet windy spring thus increases the incidence of scab. Water is essential for the germination of these spores, which will then continue to develop as long as they are in a relatively humid environment. The scab causing fungi need wet conditions to establish, so increasing air circulation in your orchard will help dry out your trees more rapidly after rain.

This can include making sure there is wide enough spacing between the trees, something traditional orchards are generally already good at, and pruning to achieve tree shapes which promote air circulation within each tree. Where incidences of scab are particularly heavy it is a good idea, if feasible, to remove or macerate the fallen leaves encouraging them to rot, as these leaves harbour the overwintering fungus that causes reinfection the following year.

Some apple varieties are more susceptible to scab than others, so if your orchard is prone to scab then it is advisable to choose more resistant varieties when planting any new trees. There are fungicides on the market to control scab in orchards, but care should be taken as these are only effective if used at the correct doses and point in the fungal life history.

Resistance to many fungicides is also developing, meaning effective fungicide control relies on a programme of several fungicides with different modes of action. Fruit trees planted in the soil another fruit tree recently occupied can lead to severely inhibited growth, which can make the tree more susceptible to other diseases and deficiencies.

Replant Disease can occur when a young tree is planted in soil formerly occupied by an older tree, particularly one of the same species, whose roots have been growing there for some years. This can leave the soil impoverished and possibly infected. More vigorous rootstocks are less susceptible to this. It particularly affects apples. It is important to plant young trees in fresh ground or at least remove impoverished soil and replace it with top soil from another area which has not grown similar fruit trees.

Planting a species unrelated to the previously planted tree can help. The longer it has been since the previous tree occupied the planting, the less of an issue this will be. Cankers are round areas of dead and sunken bark. They are often surrounded by corky, brown, flaky bark that can be cracked. Branches sometimes swell up around the canker as the bark is trying to heal over. If left, the infection will cause the loss of bark and if it spreads around the branch or trunk it will girdle it, killing any wood above it.

This is not the same as bacterial canker. This is caused by a fungus Nectria galligena that is spread by the wind and enters the tree through natural openings like scars left from leaf fall and pruning. In summer water dispersed spores from the edges of the lesions can spread the infection. In winter and spring airborne spores spread from small red fungal structures.

Canker mainly affects apple and pear trees, but can affect most fruit trees. It is often more common to get higher levels of canker infection in orchards that are on heavy and poorly draining soil.

It is common to have low level canker infection in a traditional orchard and impossible to remove all traces of it, however keeping the infection down will reduce the chances of it spreading. Healthy trees are often able to fight canker themselves, healing over the wounds caused by the infection. However if your trees are old, or infection levels are too high it is necessary to remove it. Prune canker out of your trees, cutting back to uninfected wood.

Cankerous prunings should be removed from the site and burned, as the canker fungus can spore and spread even from pruned material. Although no variety is completely resistant to canker, there are varieties that are more resistant to infection.

If your orchard has heavy canker levels it might be worth considering more resistant varieties when gapping up. Bitter pit is not a disease but a calcium deficiency, generally caused through lack of water which transports the calcium around the tree and to your fruit when they are developing. Bitter pit causes small sunken pits on the surface of the fruit with discoloured brown flesh below them. They can appear when the fruit is still on the tree or when it is in storage and can give the fruit an unpleasant bitter taste.

A lack of water leads to poor calcium uptake and distribution around the tree, so it can be a problem in years when there is drought. Excessive fertiliser use can make the problem worse as the volume of vegetative growth after fertiliser use reduces the amount of calcium that reaches your fruit when they are growing.

Mulching under trees that regularly suffer bitter pit can help retain soil moisture in times of drought, and pruning out excessive water-shoot growth means the available calcium is distributed less widely, and also reduces water loss.

Some varieties are more susceptible to bitter pit than others, so if your orchard regularly suffers bitter pit you can gap up with more resistant varieties. If this is a persistent problem and you think the soil is impoverished, you can add calcium in the form of agricultural lime or foliar sprays of calcium nitrate. Bacterial canker will weaken your trees and can lead to dieback if left untreated.

Trees growing on poorly draining soil are more susceptible to bacterial canker. This is not the same as the fungal canker that mainly affects apple and pear trees. The bacteria enters a tree through the leaf stomata in summer, the leaf scars of falling leaves in autumn, or through any natural bark openings or wounds. The bacteria then survive the winter in small cankers that they create. The earliest signs of infection are on the leaves in summer where you will see brown spots surrounded by yellow discoloration.

As these spots dry they can turn to holes in the leaves, which can also fall prematurely. Cankers on twigs branches and sometimes even the trunk are the other main symptom. Within the canker areas the bark shrivels, becomes darker and looks wet.

These cankers can girdle the branches, causing dieback further up the branch and can kill the entire tree if they girdle the main stem. The fungus causes the fruit to develop soft brown areas of decay which quickly spreads to the whole fruit.

Concentric rings of yellow-white mould will then develop on the infected fruit, which subsequently shrivels and persists on the tree through the winter. Remove and destroy affected fruit, including the shrivelled infected fruit that remain on the tree. Affects : mainly ornamental flowering cherries but can also affect plum pear and apple blossom.

Flowers and shoots will wither and hang, smelling distinctly sweet. The infected area may be covered in tiny buff coloured pustules. The symptoms of this fungal disease can resemble frost damage or fireblight, but fireblight does not affect stone fruit. Remove the infected material by pruning to healthy wood.

Then inspect your trees once every three or four weeks after the petals have fallen to see if you can see further infection. Any infected wood should be cut out and burned. It is widespread in south and central England, with occasional occurrences in northern counties and can be spread and harboured in hawthorn. Fireblight is a bacterial disease, Erwinia amylovora , spread from plant to plant by rain splashes, birds, bees, direct contact with infected plants and indirect contact through pollen and nectar of infected plants.

Infection enters the tree in spring through lenticils, blossom, or wounds in young shoots. Tissue that is injured through insect damage or hail or otherwise is highly susceptible to infection. When infected, the bacteria spreads through the tree through the vascular system, which can kill the tree if it spreads around the main stem. The bacteria emerges from dormancy in spring when it oozes from cankers.

Late spring or early summer is when the risk of infection is highest, with wet weather increasing this risk further. The cankers become dormant again in autumn, where it provides a source of infection again the following spring.

As the name suggests, one of the symptoms of fireblight is the burnt appearance of the infected blossoms and twigs with whole blossom clusters turning brown and wilting after infection. Leaves appear as though they have been scorched from underneath, twigs blacken, shrivel and often curl at the ends. Fruits affected shrivel and turn brown or black, remaining attached to the tree. In advanced cases you will see oozing, discoloured sunken cankers, surrounded by irregular cracks in the bark.

The ooze is a translucent amber or reddish colour and contains large quantities of the bacteria which will cause secondary infections in the tree or distribute to other individuals. Tissue under the bark may be discoloured to a reddish-brown. Removing affected wood is the best way to control fireblight, there is no effective chemical control available. The spread of fireblight can be stopped at any stage detected by pruning out infected wood.

Make sure to cut the branches back to uninfected wood, if your branches are under 25mm in diameter cut at least 30cm below the last signs of infection, which shows red staining, and 60cm below for any branches bigger than this.

Tree Topping – What You Don’t Know is Killing Your Trees

Dieback is a progressive death of fruit tree branches and twigs caused by various diseases. Trees may suffer initial decline but ultimately survive, or they may die within a year. Generally, these diseases infect mature trees compromised by poor health or environmental stresses. Because weaker trees have lower disease resistance, they are unable to fend off pathogenic attack. Fruit trees show subtle symptoms at the onset of branch dieback diseases. Initial telltale signs may show first in their leaves before their branches die. Leaves may be slower than usual to emerge in spring and they may turn pale green or yellow. Leaf margins and tips may scorch, which makes them turn brown and drop prematurely. As a disease progresses, twigs and branches die and trees may try to compensate for these losses by producing suckers on branches and trunks. Galls and cankers often infect fruit trees.

Why Is My Fruit Tree Dying? Common Fruit Tree Pests and Diseases

Trees and shrubs affected by the decline and dieback syndrome may die within a year or two after symptoms first appear or in some cases survive indefinitely. Corrective practices such as proper watering, fertilization, and pruning are not guaranteed solutions in all cases. Decline and dieback may be caused by many factors Figures 2 and 3 and is usually progressive over several years. Trees and shrubs of all ages may be affected, although this disease complex is usually associated with plants that have attained some size and maturity. Symptoms of decline and dieback are often subtle, slow in developing, and usually uniform throughout the crown.

How to Winter Prune Apple Trees

Pruning and training are two of the most important cultural practices for managing fruit trees and begins at planting. Pruning is simply the removal of parts of the tree. Training is directing the growth of the tree into the desired form through pruning, limb spreaders, clothespins or other means. There are many reasons for pruning fruit trees, probably the most obvious is to reduce tree size for its allotted space in the orchard. It is important to keep the aisles open for orchard equipment and easier harvesting.

How to give your new trees a good start in life. These leaves will then wilt and dry out, which can eventually lead to tree death.

Fire blight is a common and very destructive bacterial disease of apples and pears Figure 1. The disease is caused by the bacterium Erwinia amylovora , which can infect and cause severe damage to many plants in the rose Rosaceae family Table 1. On apples and pears, the disease can kill blossoms, fruit, shoots, twigs, branches and entire trees. While young trees can be killed in a single season, older trees can survive several years, even with continuous dieback. Fire blight first appears in the spring when temperatures get above 65 degrees F. Rain, heavy dews and high humidity favor infection.

Pruning is a very important part of proper apple tree care and maintenance; however, many people think the task overwhelming. Keep these things in mind when approaching pruning your apple trees:. NOTE: This is part 8 in a series of 11 articles. For a complete background on how to grow apple trees , we recommend starting from the beginning. When your apple tree is dug up from our fields to be shipped to you, and any time a tree is transplanted, the root ball loses many of its fine feeder roots.

The pruner must maintain this structural integrity and know a little tree biology and proper pruning principles. The best time to prune trees is during the dormant period, usually in late winter from November to March. Dead or diseased branches should be removed as soon as possible.
