potted lime tree will not grow fruit -
we have a dwarf lime tree in a pot. we have had the tree about two years and it looks healthy. It is about 3 1/2 feet tall. it forms blossoms that convert to fruit buds, but the fruit buds do not grow. I fertilize it about three times a year and it is on a drip system for water that seems more than adequate. what should I be doing to stimulate the tree to take the fruit buds to full fruit size? I am quite certain it is a behr (sp?) lime tree.
It seems you are doing everything correctly but let me review just in case.
We recommend fertilizing three times per year: January/February, April/May, and August/September. See the following link for more details. http://cals.arizona.edu/maricopa/garden/html/pubs/MC91.pdf
The drip irrigation should be sufficient to make water reach the bottom of the root zone. How often you water depends on when the soil dries out and that is related to seasonal weather conditions and the size of the container. You can test the situation by inserting a soil probe into the container. If it is moist it should slide through easier than if it is dry. Here is another publication below with information on irrigation. Keep in mind this is about trees planted in the ground. Regardless, there is some good information about citrus water needs.
Please let me know if you have additional questions.
