Apple & pear scab
I have had a great problem with scab this year, on both apple and pear trees. What should I be doing to get this disease under control?
Unfortunately the UK climate is so wet that scab will always be present. The following might help.
In winter, clear up fallen leaves and infected fruits. At other times, watering fallen leaves with diluted urine, or any other high nitrogen liquid manure (such as nettle ‘tea’) will help kill spores. Prune trees regularly to maintain an open centre to increase air circulation. Apples that are particularly susceptible to scab are: Cox’s Orange Pippin, Gala, James Grieve, and Laxton’s Superb. Pear: Williams Bon Crétien.
