Our drive is getting on for 100m long, bordering a wooded stream. We would like to line it with snowdrops but I'm worried this is a colossal task as some sources claim I need 100+ bulbs per square metre. Ultimately we would like a the whole area to be drifted but appreciate this will take some years.
What is the best way to set this up so it will look OK with fewer bulbs, and spread nicely? What is the minimum bulbs we could get away with that it would not look silly, and should they be planted individually or in small clumps?
I don't have a wide shot in season but:
The woodland is on the right of the drive, falling away into a stream just past the line of trees - the close-up showed it this spring around the stream.
