premature apple drop
Premature fruit drop is not remedied by fertilizer application. It is caused by a combination of the variety you have and the weather conditions. Some varieties like McIntosh normally exhibit early fruit drop. Warm to hot weather like we have had this past two weeks and/or lack of moisture can aggravate the problem as well. Finally some seasons maturity is just earlier than normal because of weather conditions early in the growing season. Apple variety maturity can vary as much as 10 days from one year to the next.
