Two herb questions, my excuse is that they share the same window box (inside).

I started both from seed last year and had excellent growth, more than I could use.

The Chives slowed but were usable all winter. Now they are getting more sunlight the stems have split and look more like grass. Is this caused by lack of water / nutrients?? Should I cut them back?

My Basil during the winter formed brown solid stems approx 1/8th inch. They are now growing new green leaves. Are they best left alone?

Kind Regards
Brian
