I'm growing a lime tree indoors. It's about 7 or 8 years old now and finally producing some flowers and also fruit. I just read a home guide from SFGate that manual pollination is required to grow fruit, however I didn't do any on my tree, and there are a few flowers that seem to be growing little, tiny limes from the centre of the flower. Do you have any idea why this may be?
Sfgate and the other content mills are crap. Lots of times articles are written by people with little or no experience other than the ability to paraphrase. I remember reading a lawn care article written by a hair stylist. Most of the time they just copy stuff from other sources and reword them.
This page from a dwarf citrus grower indicates you don't need to pollinate indoor citrus trees as they're self pollinating. I'd trust them over some "farm boy"/suspense writer.
