What causes this?

[Headhunter]

I have a Meyer lemon tree that only has one fruit on and no other flowers coming. It's been raining quite a lot here in Thailand and think maybe I don't have enough drainage going on. Should I add some sand to my soil mixture or something else to help in drainage?

I have a problem with leaf curl also so need some help there also.

I got the tree from a friend of mine and his trees put out a lot more fruit but some of his trees have some ugly looking fruit and hoping my tree won't get the same thing.

Thanks for any help you can supply,

Chris

Looks a lot like early form citrus black spot. Not good. Take to expert over there.

Hi Headhunter! Is there any abnormality that is visible on other parts of the tree - leaves, twigs, bark?

My friends trees look pretty good over all but do have the curly leaf problem as my tree does. I only saw the bad fruit on one of his trees. They all have plenty of leaves and do bear a lot more fruit than mine. The twigs and bark all look healthy. I'll try to get over there to take more pics and take some pics of my tree also.

Thanks for the help.
