Should I pinch out a Delphinium?
This is my first post here and I hope that some of you can help.
I planted three Delphinium plants last Autumn and they are all doing well. Two of them are lovely and bushy, but the third one just has one stem and is now producing a flower spike. Should I pinch this out to encourage more growth from the plant or should I leave it? I have tried to find info on pinching out delphiniums on the web but with no real luck. I would hate to pinch it out and for it then to not flower as the garden is very new (only just finished landscaping in September 14) and there are very few plants that are coming into flower, but I do want to encourage healthy plants!
Any help and advice would be most appreciated. Many thanks.
