Q.Lemon tree
My lemon tree has produced excellent lemons for years. The current lemons are much smaller and splitting ?
Thanks
Gayle
Weather changes and extremes can cause the Lemons to split. This is not anything that you can control.
Heavy rains during warm spells can also cause fruit to split.
If you also fail to water, then water heavy, the results will also be the same.
Soil should be a constantly moist but never soggy.
Dry weather spells followed by high humidity can also cause this issue.
Mulching the tree will help the tree moderate it's moisture levels.
Small fruit can be due to lack of pollination and nutrient levels.
Follow a good fertilizer schedule.
