Fig tree isn't fruiting much

Last summer we moved into a new place with a mature fig tree, must be at least 15 years old. We got a big harvest from it last summer but this year it has probably less than a a quarter of last year's amount. It did have a bunch of small figs that ended up falling off. We had a couple of +90F days here in Sacramento less than two weeks ago so I'm wondering if that could be the reason. I gave it a very small amount of fertilizer in the beginning of spring. I don't think I'm over watering it.

I though this was a very easy tree to maintain. Water once a week? Should I be giving it regular fertilizer throughout the spring? Is it too late to give it a good dose of P-K fertilizer?

I don’t know that much about fig trees, but I did some research and the most common reason for a fig tree dropping its fruit is not getting enough water. I don’t know if giving more fertilizer at this point helps, maybe someone with more knowledge will see your thread and help!

15-year-old fig tree is also quite old. It could also be that it’s quitting it’s fruit production job to enjoy retirement days.

Update,

It's now fruiting for a second time on the new growth.

i cut my fig trees back after they fruit, not sure how often you're supposed to do it but i do only get fruit on new growth. my neighbor has a tree that gets almost 3m high and she cuts it down to the ground every 3 years or so, it always stops me in my tracks when I see she's cut it but she always has fruit....

Hi Barhos,
I am not familiar with figs specifically, but I know that with most fruit that grows here in Maine there is one year with a heavier fruit load and a year with a lesser fruit load, and they alternate like that. If a tree is not pruned, it seems to take this more to an extreme, where you get tons and then almost nothing then tons and then almost nothing. Was the tree being taken care of before you bought this place? I know figs are quite different from things like apples, pears, and peaches, I'm just guessing here.
