Hydrangeas

Everybody needs a hydrangea or ten

Contents

Propagation

For panicle hydrangeas:

  1. In July / August / September, take a semi-hardwood cutting 3-6 inches long just below a node.
  2. Leave the top pair of leaves and remove all others.
  3. Dip in rooting hormone and then put in a prepared milk jug, firming soil gently to secure it. (don't use that crap potting soil from ace hardware, it's all clay!)
  4. Close milk jug, tape it shut. Write - with grease pencil - date of prop. and plant type
  5. Place it on north side of house, out of direct sun and try to forget about it for a while (you're going to futz with it, knock it off)
  6. Check in about a month for roots by testing for resistance or looking at bottom of jug.

Hydrangea paniculata 'Limelight'

There were three distinct limelight Hydrangeas (Hydrangea paniculata 'Limelight') when we moved in in 2015. As of 2026, we have minimally pruned them - just dead wood- but they need rejuvenation pruning. The patent has expired1 and so they can be propagated freely.

2026-09-20 — The panicle hydranagea on the eastern side of the house has died entirely. It was spindlier every year, and I think it received a couple summers that were simply too hot. It was in full sun all day, which didn't help. The one along the border by the ADU is healthy but a bit overgrown. The one by the driveway (southwestern corner of house) is incredibly overgrown. This will be cut back somewhat next spring, but I plan to take cuttings now for my mom and EM + WB (don't know if they actually want them, but I'm doing it anyway). 12 cuttings are planned.

Hydrangea quercifolia; Oakleaf Hydrangea

I don't have one but MS said I can have some suckers off hers.
