Question
I live in the Los Angeles area.  I have a dwarf Key Lime tree in a pot.  It is a very very large pot about 20 gal. The tree is in full sun, Southern exposure.  I got the tree 5 years ago. The tree get full of flowers every year and they turn in baby limes probably a couple hundred.  They all fall off and the tree bear no fruit.  Also when the flowers appear the leaves begin to fall off.  It loses almost all the leaves then after all the fruit falls off the leaves grow back. right now the tree is full of leaves but no fruit.  What can I do?  I am about ready to throw the tree away.
Thank you for any help you can give me.

Hi Cecilia,  Do not throw your tree away, it is actually doing what it is supposed to do.  A citrus will loose a lot of its inner leaves then put out flowers than fruit.  It needs to shed these leaves to make room for the fruit.  So now we need to make sure you are consistant in watering your tree, if you do not it will abort it fruit.  Secondly you may be getting fungus in the blooms and it is not being pollinated enough to hold the fruit.  I would suggest a fungicide or even better a product called Atomic Grow which is organic.  It will not only get rid of any fungus but make more nectar in the blossoms to attract the bees to pollinate your tree.  You tree will become very healthy to fight of other problems that citrus encounter.  kathy
