Just read an article in Colorado Gardener Newspaper which had a couple of good iideas
In answering a question about damaged Agaves and succulents this winter (past we hope) Kelly Grummonds of Timberline Gardens said:
"Deep Freezing temperatures and wind chill will cause these symptoms [bleached leaves and other winter damage] In my garden even my 20-year old Agaves are showing some type of damage. Every few years we see this so I have gone to covering my prize plants with Styrofoam boxes from November until April. Another technique is to cover them with garden frost cloth supported by wire nursery baskets or home built frames. It saves us from this kind of disappointment and heartache. Fortunately, most will recover"
Thought the idea of the boxes or cloth was a good one. We are still getting very cold winds and some freezing temps here and we know it can take a while to get past the danger time.
Think I will go out and put a few styrofoam boxes in place.
