2. Some places have highly changeable weather conditions. For example, day and night temperatures have big differences that also cause buds to fall off. Rainy weather after dry conditions also causes buds to fall off as it acts the same way as nitrogen works and causes the bursting of new growth i.e. buds.

3. Insects also cause buds to fall off the plant, for example the Harlequin Bug causes bud drop.
