Stupid question around bulbs

[omnishambles]

So as in every year I ran amok online and got some bags of spring flowering bulbs/corns etc.
The anemones are already coming up which I was a bit eyebrow raised but just now I see that other bulbs are as well - already through the squirrel proof netting - does this mean that the frost will kill them?

When did you plant them? I don't usually plant mine until oct/Nov, when it's colder

I believe they need the cold to stay dormant, and when it warms up next year that is the trigger to grow.

How deep did you plant them?

Grape hyacinths will already be up by the way, their leaves start emerging in the autumn.

I planted them maybe 10 days ago - they are a mix of new bulbs and old bulbs that I dig up and replant - they could be grape hyacinths. They are a mixture of depths according to their size in a lasagne.
Will the anemones be ok?

Anemones will be fine. The point about bulbs and corms is that there’s an awful lot of energy stored in them, and it takes more than a single year of no leaves to kill them

Many spring bulbs put up their shoots in the autumn.

Thank you. I was worried that be being organised this year I had done something very wrong. We are away for half term and so wanted to get sorted before then.
