I planted a Philadelphus in my raised border (my garden is tiny) just under 3 years ago. I cut it back last year and it's even more leggy now - some stems about 12' high!
It has not flowered at all and some of the stems break off from the main plant when it's windy. Most stems are thin and break easily anyway. As my garden is so small, I can't afford to keep any 'under achievers' so wonder if I should take it out and plant something else. I wanted it to be the focal point in the bed but it's just tall, green and uninteresting!
I'd be grateful for any advice.
