'Kew Rambler' Won't Bloom: Vigor Management for Giant Ramblers

Second Season No Blooms on Vigorous Kew Rambler

David Austin suggests Fertilome to force blooms. Gardener wants to apply in late August.

Don't Fertilize!

• Kew Rambler = EXTREMELY vigorous (20+ feet when happy)
• Current growth = energy into canes, not flowers (normal)
• Fertilizer = bigger canes, FEWER flowers
• Withhold fertilizer AND reduce water → triggers flowering next year

Management for Monster Ramblers

• Every few years: cut to ground
• Remove old canes entirely
• Medium canes → 5 feet
• New growth → keep unless pencil-thin
• Responds gratefully to hard reset

Space Reality Check

Ensure you have room for 20-foot canes. This is not a polite garden rose.
