Years ago there was a product cling set that helped increase the amount of fruit on fruit treesdo you have it?
No, we don't have a "Cling Set" product, unfortunately.
Potassium strengthens the cell walls of plants, so you might find using Liquid Potash helps:
Over/under-watering, or over-fertilising, can also lead to fruit drop.
