23. Apple, damage caused by mice during the winter months

For an apple tree, protection from mice is important. Keep mulch away from the trunk. Here is a video explaining the benefits of mulch and how to avoid mice damage.

24. Pear, leaf blister mite

The trees are infected with Leaf Blister Mite. In this case, a hedge close to the pear trees is the winter host for the mite. To control Leaf Blister Mite in pear trees, collect all infected leaves in November/December and remove from the garden, and ensure that the tree have enough water from May onwards. If the trees are young (1-2 years), consider transplanting to move the trees away from the hedge as far as possible. The best time to do this is December/January. Once transplanted, use farmyard manure and Growmore to give the trees a new start in life.

25. Pear, water shortage and competition with grass

The tree is suffering from acute starvation and continuous drought, caused by competition with grass. Grass is the worst enemy of young fruit trees. The clearest possible evidence is the appearance of black leaves on the pear trees. This shows that the trees are on the point of giving up all together. To save trees that have reached this stage, remove immediately all grass around the trunks of each tree, one square meter as a minimum. This clear area has to be maintained throughout the year, for at least the next 3 years. To alleviate the shortage of minerals and organic substances, apply well rotted straw-based farmyard manure. In March, apply “Grow More” fertilizer evenly spread over the clean soil area around each trunk of the trees. Follow the recommendations on the packet, do not over dose. Here is a video showing the same problem of a pear tree suffering from competition with grass.
