I have 2 dwarf Bearss lime trees, had them 3 years. They have lots of green leaves but fruit forms and quickly drops and I fertilized a few weeks ago, no change. It's on a sunny deck and gets watered daily. I have no idea what to do to make them fruit. Any suggestions?
Lime trees are heavy feeders and do need regular fertilizer.
Proper light, watering, and temperatures are all needed to promote fruit growth.
Here are a couple links with more information.
I planted a small Bearss seedless lime tree in a container a year ago (I live on Cape Cod). It went outside in the spring (did not flower) and back in the house in a sunny window in September. It flowered late October, and now limes have started to grow in November. Plant is about 2 and 1/2 feet tall and is very healthy. I read that this is a spring flowering plant. What is happening?
This variety of Dwarf Lime Tree produces year round.
Blooming may happen spring through fall with fruit bearing all winter long.
I live near Escondido CA and the Bearss tree is almost 2 yr, about 4 ft. It gets flowers and they become 1/4 inch fruit but soon drop. I feed the tree Miracle Grow citris granular in a 3 ft. basin and deep water monthly except in rainy season. I have a hardy lemon tree getting same treatment and thriving. Occasionally, some leaves look like they have been partially burned. I would appreciate any advice.
Your Bearss tree may be dropping fruit simply because it is so young. Here are some other possible explanations for fruit drop:
As for the leaves that look like they've been burned, this is commonly caused by harsh weather, either frost damage or sunburn. If you are applying more than the recommended amount of fertilizer, it could also be fertilizer burn:
