What causes premature fruit drop on my pear tree. Other pear planted beside it is fine.drainage is ok. I have been feeding with sulphate of potash
Freedom from weeds and grass for a 2-metre diameter circle and the potash will have helped. So pollination is a bit tricky, especially as you are in Cavan where the spring weather can be a bit cold for pears.
If everything else is okay and you think it is due to incompatible pollen, try the variety ‘Concord’.
If the drop of fruitlets takes place and they are hollowed out by grubs, this is due to pear midge. Gather all fallen fruits and destroy them to prevent carry-over of this pest.
