How to grow Hyacinths from bulbs the easy way
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 daffodils
Early 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.
