Although the following description is the procedure for pruning trees in this condition, for several reasons it is generally more logical to remove the trees or to keep them for shade. First, the care of aged, high-topped apple trees is laborious and expensive. Second, the fruit quality is generally poorer on older trees than on young, well grown trees.

HOW TO PRUNE A PLUM TREE
Insect Quick Links Anthracnose, Spot Description Anthracnose is a very common disease that attacks a very wide range of plants and trees.
When Spot Anthracnose initially emerges, small light brown spots of dead tissue emerge on the leaves and blossoms in the late spring and summer. The spots develop during the cool, wet humid spring weather. The disease is caused by a fungus that over-winters on the bark of the tree or on fallen leaves. In the spring, the fungus is spread by rain and wind, which transports the fungus to newly developing healthy leaves and blossoms.
When the tree is severely infected over several seasons the fungus will infect and kill branches. Promote the overall health of the tree with regular proper fertilizing, using the TreeHelp Annual Care Kit. Repeat as necessary. Also be sure to remove and destroy any fallen leaves. Click here for more details. Anthracnose is a very common disease that can attack a very wide range of plants and trees. If a tree is infected with Anthracnose over several seasons, the fungal disease can begin to infect twigs and branches.
Dark colored lesions or indents can begin to show on branches and twigs. Cankers can develop and branches show dieback. Continue spraying the tree with the fungicide every week until the leaves are fully developed. Once the leaves are fully developed spray the tree every 3 to 4 weeks until the end of the season. If the tree is too tall to spray, treat with the Agri-Fos with Pentra-Bark. In addition to treating the tree with the appropriate fungicide, prune and destroy dead and severely diseased branches.
Be sure to prune during dry weather and sanitize the pruning tools after each cut with a mixture of 1 part bleach and 4 parts water. Apple Scab is one of the most common diseases that attack apple trees. Apple Scab is caused by a fungus Venturia inaequalis which is most prevalent and aggressive in geographical areas where spring weather is mild about 60 to 70 degrees F and conditions are wet.
Apple Scab initially appears as small brown spots on the undersides of leaves, and then spreading to the top of the leaf and eventually to the fruit itself. The brown spots feel rough to the touch.
When a tree is attacked by Apple Scab, the fruit is often malformed and cracked and can drop prematurely. In cases of severe infestations, a tree can become totally defoliated.
The Apple Scab fungus overwinters in fallen leaves on the ground and then re-infects that tree in the spring as it is moved by the wind. If it lands on leaves that are wet it will begin to spread spores, which infect the leaf and fruit. In most cases, even infected fruit is still edible.
To control Apple Scab, in the fall remove and destroy any fallen leaves that are under the tree. In the spring, spray the tree with Captan Fungicide. The tree should be sprayed as soon as the leaves emerge on the tree and again once the leaves are fully developed. A further spraying can be done when the fruit has begun to develop. Armillaria Root Rot often called oak root fungus, mushroom root rot or shoestring fungus rot is caused by a fungus found in the soil which attacks and rots the roots of many plants and trees.
Some of the symptoms of Armillaria Root Rot include the dulling of normal leaf color and the loss of a tree's growing vigor. Often leaves may wilt and turn yellow or brown. Major branches can also die or show excessive signs of wilt.Armillaria Root Rot often causes fruit trees and ornamental trees to slowly die over a period of several growing seasons, but the rate of death can accelerate considerable if the tree is also under insect or nutrient stress.
In fruit trees, a sign of Armillaria Root Rot is often the lack of fruit production on any of the lower branches, with fruit only visible on the upper branches. The roots can also appear to be decaying and the lower trunk and cambium layer of the tree often have brown spots. As the root rot spreads it is also possible to see small white mushrooms or white fan like plaques or strands develop around the base of the tree trunk.
Infections are most prevalent in areas of poor drainage or heavy dense soil. Armillaria Root Rot, if left untreated, can cause rapid tree decline and death. Trees sometimes live for many months in a weakened state, while others will die very quickly. To control the spread of Armillaria Root Rot, remove dead trees and as much of their roots as possible. If the plant is newly infected, expose its base to air for several inches by removing 3 to 4 inches of soil.
In cooler temperatures before freezing , recover the exposed roots with loose soil. If using the foliar spray, repeat every 1 to 2 months and increase the dosage and frequency in more advanced disease cases. Bacterial Blight causes brown leaf spots often surrounded by yellow areas and rapid browning of young shoots. Newer growth is normally more severely infected. Bacterial Blight can attack a wide range of trees and is most aggressive during mild, moist growing conditions. Bacterial Blight is caused by bacteria which is spread by the wind, rain, insects or pruning tools that are not properly sanitized.
To prevent the onset of Bacterial Blight, ensure proper spacing when trees are planted. For trees with dense foliage, prune where necessary to ensure proper air circulation and be sure to sanitize the pruning tools after each branch with a mixture of 1 part bleach and 5 parts water. In the spring when conditions are favorable to the spread of Bacterial Blight, spray the tree with Liquid Copper Fungicide Spray as a preventative treatment.
If the tree becomes infected with Bacterial Blight, spray the tree with Monterey Fungi-Fighter and repeat spraying every 14 to 21 days as necessary. Black knot is visible as soft greenish knots or elongated swellings which form on the twigs and branches. Branches beyond the galls are often stunted or dead. Black knot is caused by a fungus that multiplies during wet spring weather. The visual symptoms are often seen 6 to 12 months after initial infection.
To control black knot, prune out an destroy infected twigs and branches in the fall and winter. Be sure to cut at least 4 inches below the visible signs of the knot.
After each twig branch cut, be sure to sanitize your pruning tool in a mixture of 1 part bleach and 6 parts water as this helps to reduce the spread of the fungus. Two or three more sprays at intervals of 7 to 10 days are required during the spring season.
Since an affected tree is under immense stress, it is also important to give the tree a good fertilizing. For general tree maintenance, proper fertilization and to improve the overall health of the tree, applying a TreeHelp Annual Care Kit is recommended. These kits contain appropriate fertilizer, mycorrhizal fungi and biostimulant, promoting root development and long-term vitality.
They normally appear on the upper surface of the leaf, starting in the early to mid-spring. As the disease progresses, the leaf tissue around the black spot often yellows and premature leaf drop often occurs. In cases of severe infection, a plant or tree can lose many of its leaves by mid-season. Flowering trees and roses that are infected have fewer or no blossoms as a result of the stress caused by the Black Spot.
Black spot is caused by a fungus called Diplocarpon rosae which overwinters on infected leaves. In the spring, especially in areas of high humidity and rain, the fungal spores are splashed on to new leaves and begin their infection cycle. The fungal spores enter the leaf tissue and as they reproduce they cause the black spots. Normally infections are limited to the leaves, but they can also infect new twig growth.
Repeated exposure to black spot can cause death or increase susceptibility to other infections. Repeat the spraying every 7 to 14 days as necessary, as long as the weather remains humid and damp. Avoid watering plants and trees from above, always water at the ground level. In the fall remove all leaf debris to avoid re-infecting trees and plants the following spring. If infected trees are pruned during the dormant fall or early spring period, spray the tree with Liquid Copper Fungicide Spray after pruning and be sure to sanitize the pruning tools after each branch cut.
Botrytis Blight is a common plant and tree disease that is also known as gray mold, blossom blight, bud blight or flower blight. It is caused by one of several fungi from the Botrytis species of fungus. Botrytis Blight can infect many different types of plants including ornamental trees, fruit trees, flowers, shrubs and vegetables, and the fungus, under certain conditions, can be spread between many different types of plants. The fungus normally begins to grow and multiply on plant debris such as fallen leaves and blossoms and over-ripe fruit.
Initially the growth and infection is limited to dead or decaying plant matter, but as the fungus replicates it begins to attack and invade healthy plant tissue. Once a tree or plant is infected the most visible signs of the infection are decaying fruit, spotting and decaying flowers still on the plant and in advanced cases cankers developing on the tree or plant. Botrytis Blight is most prevalent and invasive in cool, moist conditions. The first step to controlling an outbreak of Botrytis Blight is to remove and destroy any dead leaves, flowers or rotting fruit, especially if it is in contact with damp or wet soil.
Avoid using a foliar sprinkler to water trees and plants. Always water plants at the ground level and trees at the drip-line with a soaker hose. At the first sign of an outbreak of Botrytis Blight spray with Captan Fungicide and repeat every 14 days, as necessary. Brown Patch on grass appears as small circular patches of dead grass. The circular patches can range in size form a few inches to several feet in size. The patches are caused by a fungus called Rhizoctonia solani which attacks all types of turf grass.
Brown Patch is one of the most prevalent turf disease and is most aggressive in warm, humid locations. Repeat the spray 3 to 4 times every 7 to 10 days. Reduce the use of nitrogen fertilizers and reduce watering. When watering the lawn, only water in the morning. Brown Rot Blossom Blight is a common and potentially destructive disease of stone fruit trees, including cherry, plum and peach trees, as well as ornamental flowering trees such as weeping cherry and flowering plum trees.
When a tree is infected with Brown Rot Blossom Blight the disease symptoms will begin to appear in the spring shortly after blossoming.

Winter Care for Fruit Trees
Faithful reader, Karen, writes, "The recent snow split one of the main branches of my crepe myrtle.Do I need to cut off that branch or can I repair it somehow? Cutting it will ruin the tree's symmetry. The first thing to determine is if the branch is still connected to the tree. If it is completely detached, your decision has been made.
The ones you save should have plenty of lateral branches and perhaps a slight swelling or collar where it meets the broken branch. Remove one-third of the other.

Recently topped trees will develop water sprouts in the months following pruning. These often develop at or near the tips of the broken branches. Sprouting is an attempt by the weakened tree to replace the photosynthesis-generating foliage that was removed suddenly. Trees damaged in cold weather can respond similarly. Sprouting requires expenditure of stored starch energy inside the living wood of the tree and further weakens the tree.
Plant your trees in July and August, or even as late as September when the tree has already begun shooting.
