Q.Second set of fruit does not ripen
Our fig tree produced a nice crop of figs ripening in late July. Now it is full of small fruits again, but only a few look like they will ripen in time before a hard frost. Should we remove all the small ones to help the larger ones to get more nutrients to ripen?
Will you be moving this Fig indoors? If so I would leave the fruit to ripen.
If this is an outdoor potted tree I would remove the fruit after the tree goes dormant.
Here is a few links that will help.
