|I have 5 large bushes of lavender in hidcote, munstead and grosso varieties, but all have not flowered the past 2 years. they are about 4 yrs old (zone 5 CT) getting ample sun, but possibly not good enough drainage as they are planted in a bed heavy with a sweet peat (dark bark) mulch. I'd like to save & renew them. Will pruning now help? I cut the dried out stems earlier in April to no avail.

|I would prune them back now in hopes of them producing new flowering growth. Lavenders sometimes take up to 3 years to flower but if yours are 4 years old, they are certainly mature enough to flower. Try keeping the plants on the dry side (too much water will encourage green growth but no flowers) and too much nitrogen can have the same effect. So, cut down a little on your watering and don't feed your plants. Shear them back now. I hope this combination will result in lots of flowers this summer. Enjoy your plants!
