My philadelphus virginal is 3 years old. It has a lot of growth and I was expecting a dazzling display this year. All I have is one branch with about 6 of the wonderful flowers on. Too late for this year, but what have I done wrong? How can I get a display next year?
How are you pruning it? It is quite fussy in how it's done. Full details here.
That's a good link Alina. My Philadelphus took about 4-5 years before it started flowering.
Thank you both. That link looks good and I will have a go at cutting back all branches in a week or so by a third. May see the results next year.
bjay, That wasn't the advice. Prune all branches to a third, then prune a third of those down to ground level. My own Philadelphus 'Virginal' has never been pruned, ever, in fifteen years so I aim to carry out this task in a few weeks time. It's quite unruly at present.
I've had one of these for years and never done anything with it until last year when I gave it a good prune and it's absolutely beautiful this year. More flowers that I can ever remember it having before.
