« Winter Pruning in the Bee Garden »

The Bee Gardener    By Christine Casey     February 8, 2018

The Haven volunteers and I are busy doing winter pruning. I'm often asked about pruning by garden visitors: what to prune, when to do it, and how much to cut back. We prune most of our plants fairly hard to stimulate as much new growth as possible since new growth often produces more flowers. After all, making flowers to feed the bees is what we're all about!

We perform this task every year in late January and into early February. We delay pruning until then to provide forage and cover for the many birds that use the Haven and to ensure that any frost damage is confined to the outer part of the plant. Here's how we prune different types of plants at the Haven.

Herbaceous perennials

These plants are typically cut back to the base, although in the case of plants like milkweed that are late to re-sprout, it can be helpful to leave visible stems so you'll remember where the plant is located. Some examples from the Haven:

The first photo shows calamint, Calamintha nepetoides, just before pruning. You can clearly see last year's dead flower stalks with this year's new growth at the base. Cut the old stalk down to the top of the new growth.

The next picture is sedum 'Autumn Joy', Hylotelephium 'Autumn Joy' just after pruning. Isn't the new growth cute? It looks like tiny heads of lettuce! I prune this plant earlier -- in late fall or early winter -- as the hollow stems make great overwintering sites for beneficial insects like ladybird beetles.

The final example is 'Walker's Low' catmint, Nepeta x faassenii 'Walker's Low'. No need to be gentle with this plant; we prune ours with electric hedge trimmers. The photos show the same patch of plants before and after pruning.  

Calamint before pruning. Note the new growth at the base of the plant.
