Asparagus is always a delight in the spring. It’s the first thing to arrive and harvest in the outdoor garden, but after three years I have found that the asparagus needs just a little help staying warm in this cold climate.
The first year of this garden I planted “Millenium” asparagus crowns, hardy to Zone 3, “a male hybrid asparagus variety bred in Ontario, Canada. The plant is hardy, tolerant to cold winters.” The second year I couldn’t wait and harvested about enough for one meal. The third year (2019) I was able to have a few meals of delicious asparagus.
We do have to offer a little help in early spring, to keep the asparagus from freezing. We get a lot of warm spells throughout March and April with daytime highs in the 70’s. However, some of the nighttime lows can reach 0°. Sometime around the end of April the asparagus will begin to come up, sometimes just reaching a pick-able size, only to freeze overnight. This year (2019) we covered the asparagus with frost cloth at night, and added warm water bottles around the plants to keep them warm and healthy, and less likely to freeze. I think it helped, and next year we plan to devise a better way to keep them covered and warm.
