Coronation Gold yarrow is one of the few plants in my garden doing spectacularly well. It's out by the driveway, in too small a space, tightly planted against the fence and flopping over.
I just put in a Rocky Mountain penstemon next to it on the left, which I hope will make a nice complement. I like the loose abandon of this dramatic plant, but it's too floppy.
So I plan to rectify the situation:
In fall I will lift and divide it. One division is going behind the cardinal penstemon by the garage stoop, to fill the empty spot against the wall where the table had been.
The remaining division will get replanted in the driveway strip, but I need a plan of action to control it. I'll need to replant it out away form the fence more (not much room to do that), I'll need ring supports, and I will need to chop back the front of it for shape in spring.
Here's the plan:
๐ Fall
❄️ Winter
๐ฑ Spring
That provides:
Don't overdo the chop the first year.
Since I'll also be dividing and moving the plant, start conservatively—remove only the top third of the front stems. Then be more aggressive the following year.
- Cut the plant back when it dies down.
- Lift and divide it. Coronation Gold benefits from division every few years because the center can become woody and less vigorous.
- Replant the main division 4 inches farther from the fence. That extra breathing room will let the stems arch naturally instead of immediately hitting the fence and then spilling onto the driveway.
- Plant the extra division by the garage stoop behind the cardinal penstemon.
- Install one or two support rings before the ground freezes.
- Let the plant get established.
- Early to mid-May perform a Chelsea Chop on only the front half of the plant. Cut those stems back by roughly one-third to one-half.
- Leave the back stems alone.
- taller stems in the back to soften the fence,
- shorter stems in front that help support the taller ones,
- a longer bloom season because the chopped stems flower a week or two later.
