The Q&A Archives: Key Lime Tree

Question: What can I do to promote fruit on my Key Lime tree. It gets lots of blooms, but any little beginnings of fruit drop off.

Answer: Your key lime tree is very normal. A mature blooming citrus tree can produce as many as 100,000 blooms depending on the age and size of the tree. Within a few weeks of bloom 80 - 90 percent of the flowers will drop from the tree. This period is called the Post bloom Drop. Of the remaining blooms that successfully produced small fruitlets only about 2-4 percent of the fruitlets will remain on the tree to mature and develop into harvestable fruit. It is normal for only 1-2 percentage of the spring bloom to produce mature harvested fruit. The percentages will remain approximately the same as your tree ages and increases in size, but the actual number of fruit will gradually increase.
