My Meyer Lemon tree was full of flowers this spring. I hand pollinated them using a q-tip, along with help from some insects, when the tree was outside.
After the blossoms fell off, it didn't produce fruit. Is this common? It is three years old and very healthy.
I made a blog post about pollinating the lemon tree: http://simplyresourceful.blogspot.com/2015/04/how-to-pollinate-meyer-lemon-tree.html
I live in WV. I took it outside when the weather was warm in early spring but kept it inside during the cold winter. I use citrus tree soil and fertilize with chicken compost tea. The chicken tea keeps the leaves from turning yellow & it works great for the other tropical plants that I have. We live in the mountains so there is no "true" sunny window here, but it is always placed in the sunniest location on the south side of the house. Yes, it is well-watered. I use a moisture meter monthly. The tree is currently putting out new leaves.
UPDATE: The tree is blossoming again. Let's hope for the best.
