i think one or two would be fine. but i knock them all off on the yr they were rooted. one the second yr, if the growth is not robust, i also knock them off. i mean... i want to grow these to get good figs. one or two year wait isn't so bad. besides, i have fig bearing age trees to meet my needs. from what i have read, if the tree put on too much energy into growing figs, they might not put on many figs following year, and they might also have an issue growing.
few trees that i have, other than Kathleen's Black, put on figs second year from rooting. the growth was great and they put on very lttle figs, so i let them keep them. on 3rd year, they put on good quality figs in good number. this is their 4th year and 3rd year putting on the figs. can't wait :) now KB.. i hope it's good this year. along with White Greek. i heard so many good things about White Greek, and it put on figs on second year. about 6 of 'em. they were great looking figs, but it was.. there was no taste what so ever.. like eating air with fig texture. i might move WG to bigger container this year to see if that helps.
