This season there is an abundance of fruit on the lotsa lemon tree which is planted in sandy soil with mulch and in full sun. The photo is of the problem that occurs year on year.
Answer:
Hi Paul, It is a bit of a mystery to me. It could be sunburn through early morning dew. If the fruit is OK to eat, then ignore it. You don’t say how often you fertilise it: do it in August and February each year: a full dose in August and half dose in February. Don
