I was a small owner/grower of a small specialty nursery for 18yrs. I like to write about my experiences in the hopes that it will help someone else.
"Overwintering Perennials and Herbs"
That is more or less how I did it this winter. Except I used bales of straw instead of wooden frames and I spread a layer of straw over the plastic covering. I'm hoping for better results than I've had with other methods.
What is your estimated success rate doing this?
Thank you, Catherine. Lovely site you have, with much interesting content.
We block our perennials out on the ground, cover with a permeable fabric, and that is it until spring. Never a problem with rodents - yet, at any rate, and it has been over 15 years of this.
The straw bales should work out great, because of the insulation. I chose the wood frames because they needed to be permanant frames. I overwintered in them and sold out of them. Just make sure you bait, especially with straw frames.
