Dry conditions can exacerbate early fruit drop, so you may just be dealing with the fallout (no pun intended) of a droughty year&#8211;I have heard at least one grower report the same issue. In addition, apples release ethylene into the air around them as they ripen; if the fruits are crowded, that ethylene accumulates in local pockets and can increase the risk of individual fruits releasing too soon. The best way to prevent this is to thin the fruit earlier in the season&#8211;always bittersweet for the home gardener, but thinning generally produces a better crop in just about every\u00a0food plant. One or both of these is most likely the culprit.<\/p>\n<p>It is possible that you have an issue with your soil or a pathogen of some kind (though you didn&#8217;t mention any other damage to the fruit), so it&#8217;s always a good idea to get your soil tested by submitting a sample to the\u00a0<a href=\"https:\/\/umaine.edu\/soiltestinglab\/\" target=\"_blank\" rel=\"noopener\" data-saferedirecturl=\"https:\/\/www.google.com\/url?q=https:\/\/umaine.edu\/soiltestinglab\/&amp;source=gmail&amp;ust=1663253057013000&amp;usg=AOvVaw3s1lrN96DV8CX0BqeGbF7o\">UMaine Analytic Lab<\/a>, if you haven&#8217;t before or if it&#8217;s been a while.
