The basil I bought March 29 is still doing well. This is the longest I have managed to keep basil - almost a full month. It seems to need a lot of water. I must water it every day or, at the very least, every other day. I'm sure that's what killed previous plants, basil and otherwise.
I was able to make pesto the other day from this plant. I didn't make much, just enough for one serving. Why buy pesto in a jar when it is so easy to make? A few basil leaves, some garlic, some parmesan cheese, some pine nuts or walnuts, and some olive oil. And a blender (Magic Bullet is perfect for this).
My Campari tomatoes started 12/20/13 are still alive, but not getting very big. I don't know how long it is supposed to take before they get big and start producing tomatoes. Apparently longer than 4 months. Or maybe they need fertilizer or something.
I started some more Campari tomatoes March 27 from actual tomatoes I cut in half (the way I did with the larger plant). They are doing well, though one is significantly larger than the others for some reason. Maybe it's the angle of the light coming in the window. If so, if I rearrange the plants, maybe the others will grow larger, too.
And then there is the celery I started from the root end on or around (I forgot to record the date at the time) March 19. It's doing well, though it is not getting very tall very fast. Maybe celery and tomatoes are just slow growers.
We are starting to get warmer days here in Massachusetts. It's still getting cold at night, though. One night in the past week got below freezing. It will be a while before I can take any of my plants outside.
