Getting a Jump on Spring Pruning

I have to admit, this has not been my favorite winter of all times. I am slowly working my way out of a funk, most likely brought on by my impending milestone 60th birthday. Friends in their mid-sixties, seventies, and beyond laugh at my angst. I know, it's a bit ridiculous, but there it is, sitting there, laughing at me.

Anyway, I don't like winter, and I especially don't like March. I get all excited when the snow melts and the snowdrops bloom and the witch hazel flowers and I believe spring is around the corner. Then good old Mother Nature dumps 14" of snow on my yard and I just want to crawl under the covers and hide until April.

Yesterday and today I pulled myself up by my big girl bootstraps and decided to get started on cleaning up my yard. Needless to say, it is a mess. Broken branches everywhere. Blueberries snapped off. Low hanging Norway spruce branches still pinned down to the ground by wet snow. One 'Midwinter Fire' twiggy dogwood completely encased in snow, like a snow mummy, just emerging today with half the plant springing back into the light. 

I decided to tackle my climbing roses and clematis arbor first as it is right by the garage and the snow had melted in that bed. I dragged out the ladder, set it up, climbed on, and the ladder sunk 6" in mud. I wiggled around a bit until it was properly balanced in the mud evenly (a new skill I just learned, by the way) and proceeded to prune away. The roses were easy. I cut off tons of dead wood, thinned the branches, tied them to the trellis, and voila I had made order from chaos. The clematis was also a snap- I cut it to the ground.

What? To the ground you ask? How did you have the courage to do such a thing? You must know the name of it, you must have looked it up on a clematis pruning chart... Nope. When I moved into this house I met this clematis for the first time. No label to be seen. I watched it for an entire growing season. Purple flowers appeared in July and continued coming until the fall. Aha. This clematis blooms on new wood. The following spring, I cut the entire rat's nest of vines out of the two climbing roses and pruned it to the ground. Every year since then it has climbed the arbor, entwined with the roses, and been happy as can be with it's annual new lease on life.

If you have a clematis that you don't know what to do with, you can figure it out too. By observing it for a year, you can track when it blooms. If the flowers come out in May and June and then there are no more flowers, it blooms on last year's wood. The time to prune it is right after blooming, in late June and early July, and then leave it alone for the rest of the growing season. If it doesn't flower at all in the spring but starts to flower in July and continues for the summer and into the fall, it blooms on current year's wood. You then have my permission to cut it to the ground every spring and enjoy a fresh, new plant each year. If your clematis blooms in May and June, takes a rest from flowering, and blooms again late summer or fall, it blooms on both last year's and this year's wood. You have a couple of options. If you are like many people who don't understand clematis and have consequently left your vine alone for years in fear of damaging it, you have a giant tangled mess on your hands. In that case, cut it down in the early spring, sacrifice the early bloom season, and get control back of the plant. You will still enjoy the late season flowers. If it looks pretty good and you don't feel like it will tear down the trellis anytime soon, do a light pruning in the spring and a second light pruning in late June or early July after the first heavy bloom period finishes. 

Poking around outside these last few days was good for my spirit. It soothed my soil to get muddy and use my muscles again. When studying the plants up close, I can see they are getting ready for spring just as I am. Buds are swelling and I find myself being extra careful not to step on the bulbs that are poking their noses up everywhere. There's hope!

  1. Finally, a clear explanation of pruning clematis. I kind of understood new wood / old wood, although I found myself examining shrub twigs to tell which was new and which was old, and getting puzzled about that. And I do get that there are 3 clematis groups. But it seemed a little obtuse. This made it all no-fuss and incredibly self-evident. Thank you!!

    Like all things in gardening it is so simple when you look around, observe, and pay attention.
