When bulbs get cramped for space they throw up leaf not flower. To improve the flowering from congested clumps of Daffodils they can be divided in June.
How to Divide Daffodils
- Tip out the bulbs grown in pots and clean away loose compost.
- Lift clumps from the border with a spade.
- Tease apart the bulbs, discard very small or misshapen bulbs.
- Grade the bulbs by size, the larger bulbs should flower again next year.
- Smaller bulbs need to be grown on to increase their size – put them 2″ deep in a pot of John Innes No2.
- Improve the soil before replanting with compost, leafmould and a balanced slow release fertilizer.
For bulbs naturalised in grass, wait until autumn. Strip back the turf then divide the bulbs.
Handle fresh bulbs with care as they bruise easily and that can cause rot.
After replanting water the ground and mulch over the planting spot.
Other Bulbs to Divide

- Muscari or Grape hyacinths – Divide in summer replant 3 inches deep.
