Mark, the Vortex I was referring to was the one, that occurred about 3-4 yrs ago, when I dipped BELOW my zone, into the zone 5 range (-13F and -14F). The cold weather we just had, doesn't qualify as a Vortex, in my book, because I only dipped into temps that are normal for z6 (between 0 and -10F). |
I used 2 Walls o Water... the top one supported by a ring of plastic-wrapped concrete blocks that encircled a bottom Wall o Water, on the ground. The top Wall o Water was covered with a Styrofoam rose cone. That protected enabled the plant to endure z6 range minimums, unscathed.
That z5b Vortex winter, in which the plant died back to the ground, I had been planning on using a different method of protection, the following winter, since the plant was getting tall (especially, after tying up the leaves and petioles, which made the plant taller).
If my plant survives this winter, z6 (so far), and since it has finally returned to its pre-Vortex height, I will probably use a leaf-filled plastic-wrapped chicken wire cage, with a pipe heating cable, coiled inside. This will work for a taller plant.
