Fruit trees not setting fruit

In Spring of 2009 I put in a dwarf lime, dwarf lemon, dwarf orange, and dwarf tangerine on my back hillside in full sun. I give them each a deep watering once a week by hand and they get 10 minutes of sprinklers twice a week in addition. I fertilize with organic citrus fertilizer every quarter, and put copper on the stems to keep snails away. The trees looked great with new leaves and then flowers, however now that the flowers are gone I see no fruit except on the tangerine tree. What could the problem be?

Hi Roz,

Here's a good article from Ron Vanderhoff about problems with fruit trees: www.themulch.com/fruit,-nuts-and-vegetab...-trees-with-no-fruit

I hope this helps
