Ketoxol Although I've read that basil should be rotated on a 2-year rotation, we've had no problem with planting it in the same area 2 years in a row, but maybe I just like to tempt fate! Harvesting Basil You can pluck leaves from your basil once it has about 8 leaves. Snip the top of the plant off, leaving 4 leaves; this will encourage the plant to expand laterally (it'll get bushier). You should be able to harvest leaves up until the first frost in the autumn. . https://www.healthinsideinfo.com/ketoxol/
