Snow protection for herbaceous perennials

Hi, snow is forecast next week and I'm wondering if its necessary to use fleece protection. 

In particular, I have a flowerbed with lots of perennials starting to grow - about 2-3inches tall. Will these survive unprotected? If they need covering, would I just lay a sheet of fleece over the whole bed, perhaps holding it in place with bricks at the corners?

Thanks

Hi @charlotte

This is a great question, especially for new gardeners.

The quick answer is no. You don't need to fleece 99% of herbaceous perennials. This plant group are tough enough without needing additional protection over the winter even in heavy snow or frost.

The plants that do need winter protection from frost are:

  1. Half hardy plants
  2. Tender plants
  3. Some bog plants like Gunnera
  4. Seedlings grown early in the year
  5. Hardy tropical plants like palms
  6. Penstemons

Here's my detailed guide to plant types to help as well.

For the most part, though, herbaceous perennials will be fine even if they've just been pruned back with the winter chop. They have evolved to cope with cold winters, and once the winter prune happens, you're only cutting back through old dead material anyway, not to nice new green shoots. Check out this video to show you what I mean.

So stay in the warmth instead!

Happy gardening.
