Something happened while I was away to my windowsill "lawn" (actually weeds that I sowed from seeds found in the street). When I left it was green and luxuriant, now it's all wilted and blackened. Frost, I suppose. But the funny thing is that in the planter right next to it, the rocket I sowed at the end of last summer has started sprouting, along with some other random stuff and -maybe, though probably not because it doesn't smell like it- tarragon.
I brought one of the planters inside today and sowed cherry tomato seeds. I didn't remove the old soil but only put some new one on top, I hope that will be enough to nourish them (this planter already had cherry tomatoes last year). I should probably put more fertilizer this year. Unless, of course, I forget again
