Plants in greenhouse too advanced, ok to chop? HPs wallflowers, delphiniums etc
The heat has brought on a lot of flowering plants in my greenhouse (I have had the window and door open) and they are shooting up flowers, even though they are quite small. I wasn’t going to plant out just yet. It seems sensible that I can take the flower stalks off, yes? But I wasn’t sure. It’s mainly wallflowers and delphiniums that are going for it.
