Question about Hydrangeas

j_r said:

I thought Oakleaf hydrangeas bloomed on old wood, so I've been resisting cutting them back. But they're wildly overgrown and leggy. Is it better to cut them back now, or in the spring.

And a question on the PGs -- How close to the ground do you trim them?


Your oakleafs bloom on old wood, but no worries, if you need to rejuvenate. You might want to wait til spring. For rejuvenating...just take out some of the offending stems (try to cut low on a branch instead of near it's tip) and it will produce new growth and start to fill in to cover up the legginess.

For PG, I would recommend waiting til late winter and then cut to the desired shape you want. Is it a standard (on a single trunk), or is it a multi-stem? Cut out any crossing branches and rubbing branches. And cut back behind last year's flowers as far back as desired.

Thanks! The PGs are multi-stem shrubs with a lot of crossing branches. I kind of like the aging pompoms left by the dead blooms, so I will wait to cut them back.

Yes! the dead blooms make for great 'winter interest' grin

A few questions. When should we prune? Should we cover? What should we cover with?

Don't prune any of them now.

In spring, don't prune any hydrangea that blooms on old wood (Oakleaf and macrophylla. Macrophylla are mopheads or blue hydrangea). Wait til growth starts and when it's clear which stems are just plain dead, then cut those to the ground.

In spring, you can cut all hydrangea types that bloom on new wood...PeeGee, limelights, other arborescens.

I personally don't think covering matters, but if you insist, use burlap.


I want my hydrangeas to bloom next year so I will def wrap to try to protect this winter. Do you wrap now or wait until it is snow weather?

Tah dah!

We have flowers on ours this year, too! I really missed them last year, when not one of the 5 bushes had even one flower.


I am beyond thrilled that this plant survived the winter Ina container on our patio! It has very special meaning to us as it was on the altar during our son's funeral Mass last May.

Look at what prayer can do! Check outthe yard stick
