How to grow Daffodils and Hyacinths from bulbs

Pests/diseases: Few if any pests bother daffodils. The bulbs and foliage are toxic to most insects and animals, including deer and voles. If you see vertical streaks in the daffodil leaves, dig up the bulb and put it in the trash because it may be infected with a virus. Watch surrounding daffodils for symptoms because the virus is spread by contact.

Companionship: Daffodils reach dormancy 6 to 12 weeks after flowering depending on weather and variety. The period between the end of flowering and the withering of the foliage is decisive for the future vigor of the plant. If you cut, fold or braid the leaves before they have yellowed and collapsed, you can prevent the bulb from storing the energy needed to flower the following year. You can hide healing leaves by planting bulbs with leafy perennials like browning, hostas, daylilies and ferns or by adding annuals including Vinca (Madagascar Periwinkle), Impatiens and Begonia after the daffodils have bloomed. If you are planting the bulbs in a lawn, do not mow the grass until the bulb leaves begin to turn yellow. Daffodils do well under deciduous trees, but avoid planting under evergreens and in areas where large roots are close to the surface.

Dividing/Transplanting: The best time to move or divide bulbs is when their foliage has wilted, signaling the end of active growth. Lift them with a digging fork or spade, being careful to avoid damaging the bulbs, and replant them immediately at the same depth and about three times their diameter apart. Water well.

Calendar for the care of daffodilsEarly spring: Fertilize now if you missed the autumn opportunity.

Late Spring: Water if the season has been dry, and deadhead as needed. Watch for vertical lines in the foliage and remove and destroy any bulbs that show signs of virus infection.

Summer: Try not to overwater in areas where daffodils are planted. Let the foliage harden naturally without intervention.

Fall: Use a slow-release granular fertilizer to feed daffodils now. Carefully lift and divide clumps of onions now. Plant new bulbs and include some grape hyacinths to mark the planting spot. Remove dead foliage, and cover with evergreen branches after the ground freezes. Water onion plantings properly in autumn if it does not rain.
