Marula Tree

Make a donation. Apples are easy to grow, productive, and there are cultivars, shapes and sizes for every garden. They can be susceptible to a range of pests, diseases and disorders, but in most cases action can be taken to prevent or control the problem.

Here we give answers to many of the common problems encountered. They are grouped by the area of the tree affected: shoots; leaves and flowers. Question: My tree looks as though it is dying. I dug down to look at the roots, and found that many of them were soft and brown.

The thicker ones were discoloured under the bark. What has happened? What could be wrong? Branch dieback can be another symptom of the root problems described above, as the tree struggles to take up water through its poorly-functioning root system. If the dieback is accompanied by areas of sunken, dead bark then the likely cause is apple canker. This disease can affect twigs, branches and even the main trunk. Is it harmful? No, this is a harmless lichen.

A build up of lichen near the shoot tips can suggest your apple tree is low in vigour. Question: My tree has developed lumpy outgrowths on the bark, which are covered with a white, fluffy substance.

Is this a disease? No, it is a pest called woolly aphid. The brown-black aphids secrete the white wax as a form of defence. This is the disease powdery mildew. Heavy infection can reduce the vigour of the tree. Question: The leaves of my tree have developed greenish-black spots and blotches, and are falling early.

What is wrong? Your tree is affected by the disease apple scab. This disease can also attack the fruit see below. The most likely cause is a disease called silver leaf , which can also cause branch dieback.

Question: The leaves on the young shoots of my apple tree are curled and sticky. What has caused this? The shoots are infested by aphids. The sticky substance is honeydew produced by the aphids, and this can lead to the growth of sooty moulds. The uncommon rosy leaf-curling apple aphid causes leaves to become distorted and red.

Rosy apple aphid is a frequent pest and causes yellowish green curled leaves; it can also affect the fruit see below. Distorted young leaves full of small holes may have been damaged by capsid bugs.

Question: What are the narrow, curvy, brown or white lines on the leaves of my tree? These are mines produced by caterpillars of the apple leaf-mining moth. No significant damage is done to the tree, so no control measures are required. Question: Some of the fruit on my tree has gone brown and rotten, and is covered in light brown pustules. What is the cause? Question: What disease has caused the brown, scabby lesions and cracks on the fruit?

The fruit may have been affected by the fungi causing blemish diseases known as sooty blotch and flyspeck. Question: Fruits are falling from my tree and have been eaten inside. Which pest is responsible? If the fruits are undersized, with a pinched appearance at the eye end, it is likely that the affected fruits were infested earlier by rosy apple aphids. If there are isolated, corky bumps then capsid bugs may have been responsible. Question: The fruits from my tree have brown specks inside and a bitter taste.

What has gone wrong? This is a disorder known as bitter pit , caused by low calcium levels in the developing fruit. The most common cause is a phenomenon known as the June drop although it can occur in July as well as June. This is a natural process, during which the tree reduces its total crop to a level whereby the remaining fruit can be adequately supplied with nutrients until they are mature. If the initial fruit set has been poor see below then the June drop will be reduced.

The extent of the drop can also vary according to the cultivar and the age of the tree young trees are more commonly affected. Some pests and diseases can cause fruit drop, as can adverse growing conditions such as severe drought. Possibly causes of unproductive fruit trees include:.

Quick facts. Problem gallery Take a look at some of the common problems you might encounter on an apple tree. Bitter pit. This disorder is caused by low levels of calcium in the fruit. Spray fruits with calcium nitrate from early spring to early autumn.

Roots Question: My tree looks as though it is dying. Root decay in apple trees can be the result of an attack by a root disease. The two found most commonly are honey fungus and Phytophthora root rot. Both of these can also affect the base of the stem Root decay can also be caused by waterlogging.

Branch dieback can be another symptom of the root problems described above, as the tree struggles to take up water through its poorly-functioning root system If the dieback is accompanied by areas of sunken, dead bark then the likely cause is apple canker. This disease can affect twigs, branches and even the main trunk If the dead branches have numerous pinhead-sized, raised, coral-pink pustules on the surface then coral spot is involved.

The fungus often attacks trees already weakened or dying back due to other problems Dieback of numerous shoots in late spring, with the leaves shrivelling and turning brown after flowering, is usually the result of the fungal disease blossom wilt. Dieback due to blossom wilt rarely progresses back more than cm 6in-1ft. Shoot dieback at this time can also be caused by the bacterial disease fireblight , but this is much less common.

Check for the characteristic wood staining within the affected branch. Leaves Question: What is the white powdery growth present on the leaves of my tree? Question: Why have the leaves on one branch of my tree turned a silvery colour?

Question: What is eating the leaves of my tree? The caterpillars of a number of moth species will eat the leaves of apple trees. Winter moth caterpillars are particularly troublesome between bud burst and late May as they will also eat blossoms and damage young fruitlets Caterpillars of many tortrix moths protect themselves when feeding by webbing leaves together with silken threads.

Some species of tortrix can also damage the fruit The caterpillars of codling moth see below , a type of tortrix, feed exclusively within the fruit Distorted young leaves full of small holes may have been damaged by capsid bugs. Fruit Question: Some of the fruit on my tree has gone brown and rotten, and is covered in light brown pustules.

The fruit is affected by the fungal disease brown rot.

Symptoms of several common diseases and their control measures are discussed. Brown rot is a very destructive disease of all stone fruits. The brown rot fungus Monilinia fructicola causes blossom blight, fruit rot, twig blight, and branch canker. Brown rot of ripening fruit is very common, and it generally occurs as the fruit approaches maturity.

5 Great Smelling Firewoods for Winter

More Information ». Fire blight is one of the most devastating and difficult-to-control diseases of many fruit trees, including apple and pear, as well as of other rosaceous ornamental plants. This is a bacterial disease caused by Erwinia amylovora , which can spread rapidly, killing individual apple and pear trees when conditions are right for disease development and if susceptible rootstocks are used.

Manchineel

I've been ordering for years at Burnt Ridge Nursery, and I've always been satisfied. This year I order several bundles of raspberries which I found to be robust and with extensive root systems. The nursery offers great variety and lower prices than most. I ordered two black walnut trees from this company. When the trees arrived with no roots and completely dead cambium was dark brown , I contacted the company and asked for a refund. They ignored my first email and only responded when I emailed a second time and told them I was going to contact PayPal for a refund.

Sunburn Damage in Fruit Trees

As the trees begin growth in the spring the buds begin to swell and lose the ability to withstand cold temperatures. As the buds develop, warmer and warmer temperatures still below freezing can damage them. The killing temperature is often called the critical temperature and is defined as the temperature that buds can withstand for a half-hour. Please see my Michigan State University Extension article on bud development and cold hardiness in the spring and tables of critical bud temperatures. In general, there is a range of temperatures over which damage occurs with more and more buds and flowers damaged at lower and lower temperatures until all the fruit buds are killed.

Burnt Batlow Orchards

You might assume such trees are passed it but they may surprise you with an inner desire to rehabilitate themselves, with some encouragement from you. It is often quite possible to give them a new lease of life but you need to go about it the right way. It should be completed gradually over 3 or 4 years. The first year you should concentrate solely on complete removal of any main branches that are identified as diseased or badly damaged.

Sunburn in apples: A hot problem

Apple trees can suffer damage to their fruit, branches, trunk and leaves due to disease, insect pests, environmental conditions and nutrient deficiencies. The specific symptom of scorching or browning of the edges on apple tree leaves is associated with drought, salt injury, potassium or magnesium deficiency. Often, more than one condition or deficiency may cause scorched edges on apple tree leaves. Drought conditions can turn the tips and edges of apple tree leaves brown and young leaves are especially susceptible. Browning of leaves is worse when the drought is accompanied by drying winds. After the leaf edges have dried and browned, the leaf may completely dry out and drop.

Eating fruit from the tree can cause internal bleeding and even death — earning it the nickname "tree of death".

Garden diseases - Leaf scorch

Southwest deserts provide excellent climates for growing many kinds of fruit. Many of the most common fruit trees originated in desert or semi-desert regions and, with a little help, will grow as well here as anywhere. Some of the best to grow are almonds, apricots, figs and pomegranates. Also grown successfully are apples, nectarines, peaches, pears, pecans, pistachios, plums and scores of lesser known fruits. Choosing the correct, desert adapted varieties is important with these fruits. Some fruit trees like peaches and nectarines can be purchased in dwarf form and are ideal for container and patio gardening.

Apple Tree Diseases: How to Treat Them

Track your order through my orders. If you notice drying that seems to spread from the leaf tips inwards, chances are that you have a case of scorch. Deprived of hydration and nutrients, the very tips of the leaves begin to dry out.
