The phlox seedlings are now 18cm high - in small pots in the conservatory waiting to be planted out. I haven't grown them before - do I need to pinch them out? several of them look like they are forming flowers,
I've not grown these before either but I do tend to pinch out most bedding plants. If they are looking leggy I would definitely pinch.
Yes pinch them Alex. They form side shoots very quickly which will all carry flowers.
Thank you for your help. I have now pinched them out - and also the cosmos having read another thread. Hopefully it won't be too long before I can plant them out.
