Q. I have a lemon and a
lime tree in my yard. For several years now they have only produced one lemon
and one lime. I was told that the birds are probably eating the blossoms but I
never see any signs of birds in the yard. Can birds be the cause for only one
lemon and one lime in two years?
A. I have heard that
before from some people who have citrus but I have never seen it. I think it is
anecdotal. Some flowers are sweet and if there is nothing else available
perhaps they might but not when other food is plentiful. Different citrus flower
and fruit at different times of the year.
The
reports I have seen point mostly at sparrows or finches as the culprits. To be
sure, you would have to catch them in the act. The only solution I know is bird
netting or giving them a chance to eat food they would prefer.
The
usual problem with lack of production is freezing weather soon after or during
bloom. Even before bloom. Flowers, flower buds and young fruit cannot withstand
temperatures below freezing while the tree may not have any damage at
temperatures slightly below freezing (lime) or to the low 20's (most lemons).
Another
possibility is irregular watering, particularly in the spring and summer months
when plants require more frequent watering. Increase the times you water during
the April and May months. Use a surface mulch on the soil around the tree to
retain moisture around the roots.
