When should I prune Philadelphus (2)! I should have said that I don't grow it for the flowers - it is the golden leafed one ('Aurea' I think) and it needs a really good rejeuvenation prune, not just a short back and sides. I am hoping to do it whilst it is dormant and I can see the framework of branches?
Thanks to Nikki for reply. Trouble is, I cannot get into it to prune after flowering and to be honest the flowers on this cultivar are not as good as on, say, Belle Etoile, so I grow it as a foliage plant. I was hoping to rejeuvenate it by pruning it now, whilst still dormant, and I can actually see what I am doing. I know what you mean about the old and young stems - I can see them so clearly at this time of year . I also want to take out any dead, crossing or misplaced branches. No sign of disease!
If I do it now, will it sulk all summer and look skeletal? Or will it still 'leaf'. As I say, I am not worried about the flowers.
