Forget what I said about savoring the last weeks of winter. I’m over it now and I know you are too. Spring can’t come fast enough. Sunshiny days in the 50s and 60s are just a wicked tease arriving as they still do between snow showers and polar vortices. We’re all ready for the tug of war to be over. Ready for the grass to green up and the daffodils to peak. Ready for spring to show in the trees the way it sounds in the birds’ songs. At least we can be pretty sure by now that winter’s muscles are weakening. And spring has the stamina gene. It will win out. Eventually.
Snowdrops are a very good sign that spring is on it’s way. They’ve been blooming for a few weeks already. Crocus is an even more gratifying sign and I did spot a few of the sweet little wild looking ones (Crocus tommasinianus) open on the last warm day. The honeybees were out that same day, working the witch hazel. And the skunk cabbage are up. It really can’t be long now. But any time the temperatures dip back down to (or below) freezing and snow shows up in the forecast, winter begins to feel interminable again. Until spring wins the tussle once and for all, I say we might as well force it.
I remember my mother displaying vases of bare sticks and twigs in our house when I was a kid. We’d chuckle and snort for weeks about how “pretty” her arrangements were (sarcasm runs in the family) until suddenly they actually were pretty — beautiful even — studded in spring flowers. Given my wonky sense of humor, my perennial disaffection for winter past February, and my vocation as a gardener, it’s no wonder that the practice of tricking tree and shrub branches into an early spring stuck with me. Also, it’s easy.
Simply cut a few budded branches, preferably those that needed pruning anyhow. Because pores close quickly, the stem ends will need a fresh cut, just like flowers do, right before putting them in a vase or bucket of warm — almost hot — water in a bright room. Woody stems need a little extra incentive to draw as much water as possible to the buds, so expose plenty of pith (the tissue under the bark) either by cutting on a sharp angle, or by using your pruners to split the stem an inch or two straight up the middle. Martha Stewart offers a third method involving a hammer. I’m all for finding ways to alleviate the maddening symptoms of spring fever, but the practice of stem smashing seems more likely to damage tissue than open its watery pathways. I could be wrong.
Next, wait and watch. Change the water periodically and make fresh cuts whenever you feel especially impatient. Depending on the plant and the calendar, your vase of sticks should pop into flower in two weeks to a month or so.
Forsythia is the fastest to force and will be especially quick now that we’re only weeks away from its actual huzzah. It’s not my favorite spring blooming shrub out in the landscape mostly because it’s so common. If yellow is to be the official color of early spring, why not plant acres of fragrant lime-yellow winter hazel (Corylopsis glabrescens) and northeast native spice bush (Lindera benzoin) too? But my mom and I can tell you there’s almost nothing more hilariously cheerful in the living room than a giant vase of forsythia sticks in full bloom. Except maybe a vase of winter hazel, spice bush, crabapples, quince, or magnolia. So if spring can’t come fast enough for you, go ahead and force it.
