When to Divide Bulbs
Spring flowering bulbs such as daffodils, tulips and hyacinths should be
divided in the fall. It can be difficult to locate the bulbs unless you
have marked or mapped them in the spring when they were in bloom, and this
is something to keep in mind in the spring when your bulbs are in full bloom.
Care should be taken not to damage the bulbs when digging. It is easier to
dig a large area and separate bulbs than to dig the individual bulbs.
Once you have dug up your bulbs, look them over and discard any that are
damaged, soft, or dried out, then divide large offsets or pairs of bulbs
by pulling them apart. Replant them as soon as possible.
