The Q&A Archives: Wilting Fruits On Guava Tree

Question: My guava tree is 5 year old and about 10' tall. During the past winter, the leaves turn deep purple and produced about 40 fruits. When the fruits started to grow to the size of a very small lime, they wilted and fell off the tree. I live about 3 miles from the coast in San Diego in Southern California (Del Mar). The soil is loamy and I have put a lot of soil conditioner (top soil and mulch) into the land before i planted the tree last June.(I transplanted it from a friend's house in the inland area 20 miles from the ocean). What can I do to prevent this from happening next year? Thanks.

Answer: Hardiness zones vary by species so I wonder if your tree was affected by cold weather? An over-abundance of rain could produce the same results. As long as your tree looks healthy and is otherwise growing well, the lack of fruit might be a pollination problem. The tropical guava is somewhat self-fertile but will bear a heavier crop with another variety of the same species to pollinate them. Hope this information provides some insight into what might be happening to your guava tree.
