In the first year after planting the anemones are not that robust yet. Better give them some winter protection. This also applies to perennials that you have planted at the best planting time in spring. Well suited as covering material are:
- Dry foliage
- straw
- Pruning
- Do not use conifers
Never cover the anemones with fir branches. The falling needles acidify the soil too much.
Anemones made from tuber are rarely hardy
In the vast majority of cases, anemones that bloom in spring are grown from tubers. Often it says on the package that the Onions are hardy.
You shouldn't rely on that. The tubers freeze to death at very low temperatures. This is especially true for the noble varieties of anemones, the Anemone coronaria. Your tubers must always be overwintered frost-free.
Always plant anemones from bulbs in early spring. They bloom a little later, but do not suffer from the cold.
Winter anemone bulbs frost-free
You should have the bulbs of anemones just like those of Gladiolus get out of the ground. Let them dry, remove the remaining soil and overwinter Store them in a dry, dark place with no risk of frost.
If your garden and especially the location of your anemones is very protected, it may be sufficient to protect the planting areas of the tuber anemones from frost with a dense cover of leaves.
Remove the mulch in early spring so that the first rays of sun warm the earth and cause the tubers to flourish.
Tips & Tricks
If you don't know whether your anemones are hardy, you should dig them up in the fall to be on the safe side and overwinter them indoors. Test the winter hardiness by leaving some of the tubers or perennials in the garden and see if they sprout again in the next year.
