Is it too late to plant 'in the green' bulbs?

[MsFogi]

I am an absolute novice but really want to have bluebells and snowdrops (and any other pretty flowers that grow at the base of trees!!) in the garden. Is it too late for me to plant out now? If so, am I right in thinking that my next planting 'window' is September/October?

No, they’re fine. Bluebells haven’t started flowering yet and snowdrops, although flowers are over, are still growing

I divided and replanted my snowdrops on Tuesday. Bluebells aren't flowering yet so they should be ok too . As long as the bulbs have leaves you can plant them .
