I’m new to the finer points of this companion planting business. It was only after I hurriedly stuck the garlic cloves into the container with the snap peas that I read that garlic and onions apparently have a negative effect on the growth of peas.
I think I’ll keep them there; those peas weren’t doing that well anyway, and may be finished after tonight.

Well, you can consider it a bit of an experiment. The interactions between plants can be more subtle than we think at first glance. I do like that sunflower/hydrangea combination, though.
Yes, I think that combo sounds great!
