What are those small grey bumps on your plums? Why does your fruit not have a stone inside? This article covers the most likely culprits. While plum trees are generally more resilient to disease than your apples and pears, there are several microorganisms and pests that will target them.
Some varieties, such as Victoria, are more at risk than others. The main two categories of plum tree diseases are those caused by fungi and those caused by pests. Brown rot is fairly easy to spot due to the small grey bumps that form on the fruit, underneath which the flesh will be discoloured.
Left to develop, the fruit will shrivel on the branch. Brown rot can spread quickly so we recommend removing and burning all affected fruit as soon as possible. Other fungal threats to plum trees include shot hole Coryneum blight , silver leaf disease and powdery mildew. Plum trees can be targeted by aphids, especially the plum leaf-curling aphid April to June and the mealy plum aphid July to September.
As the name suggests, the former cause the leaves of plum trees to curl. This is often mistakenly blamed on a virus. One of the biggest challenges is noticing the aphids as they are very small. The female plum moth Grapholita funebrana lays its eggs on the underside of fruit in May. Once hatched, the caterpillars will burrow into the plums, often leaving no external sign.
Inside, the pink caterpillar and its brown waste will give you a nasty surprise. The plum sawfly Hoplocampa flava is another pest that leaves few signs but renders the fruit inedible. These flies emerge from the soil in the spring and lay their eggs in the blossom.
The maggots will then enter the fruit, leaving just a small brown mark, and develop within. While some insecticides will work on these pests, you may prefer to use a pheromone trap rather than spray your fruit.
If wasps are regularly feeding on your fruit, you probably have a nest nearby. These insects strategically build their nests near sources of food so the only course of action is to have the nest destroyed or moved.
Then you have pigeons. For some unknown reason, these birds like to strip the leaves from plum trees and damage the stems in the process. While small trees can usually be protected by a net or, even better, a cage , you may need to experiment with bird scarers on larger trees. Bacterial canker can affect any tree, infecting cracks or wounds in branches. The characteristic dark, sunken wounds should be pruned out and the whole branch removed at source where possible.
While plum trees are good at surviving frost, the plums themselves are not so hardy. If your tree is in a frost pocket, and it is not too big, consider wrapping it with fleece. If you have yet to plant your tree and are worried about frost, go for a variety such as Czar, Pershore or Blue Tit which are more resilient. Contact Arborcure for a thorough survey of your fruit trees. Our experienced specialists will get to the bottom of your problem and prevent it getting worse.

Sometimes I think that pests, like scales, aphids and mites adore my fruit trees as much as I do. They feast on the juicy tender plant parts in the warm summer and overwinter on my fruit trees. Dormant oil does help control these annoying little pests and homemade dormant oils are safe for use on fruit trees. Homemade dormant oils are easy to make at home and provide the same benefit as store bought dormant oils without the petroleum because you choose the oil and it is soooo much cheaper to make your own. Dormant or Horticultural Oil is usually combined with some type of emulsifying agent so that it can be mixed with water and used as a spray. The primary way horticultural oil kills insects is by suffocating them. The oil blocks the spiracles through which insects breathe.
The dormant winter phase is the time to plant new fruit trees. Spray the wash carefully onto the tree, trying to get into every fissure and crevice.
And that is particularly true for powdery mildew of apples and crabapples, Podosphaera leucotricha. The apple powdery mildew attacks both cultivated and wild apples and crabapples. And it occurs in the all regions of the world that produce apples! Powdery mildews get their name from the white spores that are produced by the mycelia fungal threads. The disease on apples attacks virtually every stage of the plant — buds, blossoms, new shoots, leaves, and fruit. We link to vendors to help you find relevant products.

Summer brings a bounty of activities, including extra work in the yard and landscape — especially for those with an annual vegetable garden or as perennial fruiting plants and trees enter their growing season. But as the temperatures begin to rise, fungal fruit tree diseases begin to make themselves known on all types of fruit trees including crabapple, pear, apple and peach. There are a few common diseases that we deal with here in the Midwest, and knowing what symptoms to look for can help you determine how to prevent fruit tree diseases and take the steps you need to take to keep your trees healthy. Apple scab can cause brown spots and lesions to form on the leaves and fruits of apple and crabapple trees. This disease affects the leaves and fruits of both crabapple and apple trees, caused by the fungus Venturia inaequalis.
Although gardening stores often sell a range of insecticides, you can actually get rid of insects on fruit trees with products you probably have at home. Homemade insect control can save you money, and homemade remedies are often more natural than store-bought ones. It is important to keep in mind, however, that homemade insecticides are not necessarily harmless; they can still contain toxic chemicals that may harm pets or children. Gardening stores often sell insecticidal soap sprays, but you can make your own. Experts at Oregon State University recommend mixing 1 teaspoon of vegetable oil and 1 teaspoon of dishwashing soap per cup of water.

Apple and pear trees produce flowers and fruit on short stubby stems called spurs. The spurs develop on two or more year old lateral branches and will continue to produce flowers and fruit for 10 or more years. They must be preserved when pruning. Competing or crossing branches which interfere with the spurs should be removed. Long water sprout types of current growth should be removed at its origin. Follow label directions for appropriate quantities. Always check with your nursery professional to properly diagnose problems before undertaking additional sprays.
