Q.I have a Fig tree in the south of Florida since 10 years.
I have a lot of figs this year however they are very small. I have not used any fertilizer all these years but maybe that’s the reason why they don’t grow big as they should.
Someone said they need calcium, anyone out there can help with a good advice.

The recommendation for fertilizing is to top dress around the roots annually with compost. If growth slows or leaves turn pale, treat with 10-10-10 fertilizer. I also included a link to an article about small fruit. Hope it helps!
