Fruit tree maintenance in May and early June

Frequent visits to the trees at this time of year will prevent problems later.

Pests

Fruit trees are now well into the various stages of flowering and or growth. Lots of new green leaves are forming. These are very important for the trees’ wellbeing. At the same time, the leaves are excellent indicators as to how the trees are coping with various pests and diseases, which are also making their presence felt. Look at the growing points of the rapidly expanding twigs and shoots. If green fly or aphids are in the process of curling up the newly developing leaves it is important to remove the aphids with the use of non toxic fatty acid sprays or horticultural soap mixture. The garden centre stock various brands to deal with these problems.

If there are lots of ladybirds, make sure you choose a method of control which does not kill them. Ladybirds, lacewings and hoverflies are all very active predators of aphids. Caterpillar damage will be very easy to see this time of year. Remove if excessive numbers are present.

This time of the year the small song birds such as bluetits are consuming a large number of small caterpillars and feeding their young with them. These little birds are therefore a great asset to have aroud. Small nest boxes in the vicinity of the fruit trees encourage them to stay in the trees, just when you need them most.

Disease control

It is a very good routine to cut out and burn any foliage affected by peach leaf curl disease, apple mildew and scab. Do not leave it around on the ground as it will cause you even more trouble next year.

Tree canker must be cut out now, as at the moment you can still see it clearly. The same applies to silver leaf. Affected branches in plums need to be cut out and the wounds painted to prevent new infections.

Moths

Various moths that cause damage to fruit trees are becoming active from about now over the next couple of weeks. For example the plum fruit moth, whose grubs will live in the plum and greengage fruits, will cause a lot of damage. Now is the time to hang a pheromone trap in the tree.The lure will need to be replaced by early July to make sure the plums stay grub-free.

Fruit set and thinning

In spite of some earlier spring frosts, fruit set looks good in apples. It is variable in the earlier flowering trees such as plum, cherry, peach, apricot and pears. Trees of these varieties on frost-free sites, or that were adequately protected with garden fleece, may even have an excessive fruit set. Thinning should be carried out over the next 3 weeks to be effective. For example, apricots have set quite heavily and thinning is strongly recommended: it should be done now if you would like a good crop next year. The set on plums is variable. It would be best to wait a little longer before thinning, performing the operation once the level of fruit set is clearer. The same applies to peaches and nectarines.

After natural drop, in June it is advisable to reduce the number of fruitlets in a group like this

    Your post is great! It was very helpful for my family earlier this year. We have two apple threes in our backyard and thanks to your tip we have now beautiful and delicious apples. I even made some apple jam. Thank you for sharing!
