My plum tree has been on my mind a lot lately – as I wrote about last week. The kills of the last two winters have made my hypersensitive to this time of year. It’s a time of great hope and anticipation, and great fear. Will one of the first heralds of the spring be a white-decked lady, a debutante of the back yard effulgent in lacy buds? Or will the last jealous grasps of winter shear off her bloom yet again, like some jealous Disney villain? And just how cold does March need to be to kill summer’s hope?
I thought we might have escaped this year, but then the overnight forecast showed itself unkindly. I fretted in the days leading up to this weekend, wondering if my tree would make it. I found this very useful chart, upon which I anchored my fears. The temps were supposed to get down to 10 degrees. I have no idea what my backyard microclimate is. I’m not really sure what the budding stages are, but I am decided that bud swell seemed like the closest option. Even so, that looked to me like a significant killing frost – taking out maybe 50% of my buds? If only I could get the temps up for a little bit?
Adam and I swapped links on smudge pots and fans. I definitively ruled out renting a helicopter as a solution. (That’s actually a thing.) I am still not super sure I understand how fans raise temperatures, even though I read several articles on it. It also wasn’t clear to me how many degrees swing you could get using some of these techniques – and I needed quite a few degrees. But I couldn’t just sit back and do nothing and watch my plums die AGAIN! They deserve a chance!
My husband loves me dearly. He’s so patient with my insanity. After careful thinking, I decided our propane heater was too dangerous to leave running unattended – even out in the backyard in the snow. But we have this electric oil-filled space heater, see. It’s gentle heat – so no chance of fire. I’m not sure if it was enough heat, or if it could possibly make a difference. Still, under the waning light, we set up the space heater under the tree, hoping the cement wall would reflect the heat and help it stay warm.
Adam cooked up the idea to use insulation on the other side of the heater to further guide the warmth tree-ward. So he chopped up some staves, staple-gunned them to the insulation, and pounded them into the frozen soil. All without wearing a sweater, of course. We New Englanders basically give up on winter garments as a regular thing about this time of year, due to being sick of wearing them.
I have no idea if it worked. The buds all look the same, of course. The forecast shows the end of the killing frost (or at least it’s five degrees warmer tonight). The forecast looks quite chilly. The highs don’t break out of the 40s for the rest of the month. (By comparison, it got up to 70 in February.) But if April comes and goes and the green leaves break out and there were no blossoms – we’ll know that winter won despite our best efforts.
Here’s hoping to see white instead!
