Spring Blooming Bulbs – Propagating Bulbs
Guide to Propagating Bulbs – Spring Blooming Bulbs
Bulbils And Cormlets
Small offset bulbils form at the side of most bulbs, especially those of narcissi and . Such offsets can be removed by hand at lifting time or before planting and grown on in a spare part of the garden to reach flowering size.
Summer bulbs such as, produce bulblets around the base of the new corm. When the corms have dried out, the bulblets can be gently broken off for propagation and stored separately in paper bags in a cool dry place. The old shrivelled corm should be twisted off and discarded.
Dividing bulbs and corms
All hardy spring blooming bulbs, summer flowering bulbs and corms left to naturalize in the ground increase steadily from offsets; eventually they form congested clumps with fewer or poor-quality flowers.
Such clumps should be lifted and divided after the foliage has died down. Dig them up with a garden fork, deep enough to avoid damage to the bulbs. Ease theaway and separate the bulbs with the fingers, taking care not to damage the bulbs. Cut away old and dead roots, discard any bulbs that show signs of disease and separate the young bulbils that have formed at the sides of true bulbs, such as narcissi and tulips. Corms, like crocus, form a new corm on top of the old and shrivelled one, as well as many tiny cormlets on top of and along the parent corm.
Spring blooming bulbs such as narcissi, tulips and crocus need not be replanted at once but can be left to dry off until the autumn. Most other bulbs including spring blooming bulbs, summer flowering bulbs, etc. though, should go in the ground straight after division; snowdrops are best split and replanted while the foliage is still green.
Offsets from spring flowering bulbs andand corms form a ready means of increase; they vary in size and very small ones can be discarded while the larger offsets are ideal for setting out in a nursery bed and growing on until they reach flowering size. They will develop roots and leaves, but no flowers, in their first season; the larger ones will produce flowers in their second or third year. Young half-hardy corms must be lifted or wintered in a frost-free place.
