Can I mulch over newly sown annual seeds in my borders?

I'd would like to mulch to avoid weeds sprouting up in my new borders and have lots of bark chippings I can use for this. However, last week I scattered quite a few annual seeds (poppies, cornflowers, nigella) in hope of getting some colour this year (all the perennials and grasses are teeny new plants) If I mulch with bark will I prevent the annuals from germinating? Any ideas greatly welcome.

If it stops weeds sprouting, it will do the same for your flower seeds.

That's the main drawback of mulching - it blocks the self-sowers as well as the weeds.

This is an argument for mulching in the Autumn I think. I'm away to be doing some shortly but have bulbs to contend with so it will be bit-part for the time being.
