Applying sticky barriers to fruit trees
IF you want a good tree fruit harvest next year, now is the time to start protecting your plums, cherries, pears and apples.
November is the key time to attach grease bands or barrier glue to tree trunks to prevent an infestation of winter moth caterpillars next spring.
These barriers are an excellent organic solution to codling, plum, mottled umber and winter moths, which are species that have wingless females that emerge from chrysalids in the soil, crawl up the trunks, mate and lay their eggs.
The results are damaged leaves and blossom, as signs of attack start showing in spring, followed by maggoty fruit. The insects also target many ornamental trees including oak, sycamore, dogwoods, roses and hornbeams. Using widely available grease bands or trunk paint stops the wingless females in their tracks and hugely reduces the need for pesticides. Keep the sticky surfaces clean through winter, reapplying if necessary. With any luck, wild birds will also help you out next spring by feeding moths and caterpillars to their nestlings.
