How to Grow the Narcissus Golden Harvest Flower

Prepare a sunny to partially shaded growing location that has deep reserves of fertile, well-draining soils in early fall to receive new Golden Harvest bulbs. Till the top layer of dirt, add fertilizer or other soil supplements and remove any grass, weeds or other plants that will impede the growth of the flowers. Your daffodils will do best in an area where the ground does not remain wet for long periods of time.

Plant your Golden Harvest bulbs with the flat base pointed downward sometime between August and November, once the summer heat has passed and the weather begins to cool. The Purdue University Cooperative Extension Service recommends October as the best month to plant bulbs, as the mild weather allows for vigorous root growth, which promotes healthy spring blooms. The general rule is to "plant bulbs twice as deep as their greatest diameter," and spacing comes down to personal preference of how dense you want next year's blooms to appear.

Water your flower bed thoroughly after covering the bulbs with soil, and care for your Narcissi through the winter to have bright yellow flowers as early as February. Only water your Golden Harvest flowers about once a month if the winter is dry, as overwatering can result in bulb or root rot. "Golden Harvest" Narcissus flowers can withstand temperatures as low as 15 degrees Fahrenheit; gardeners who live in areas with cold winters should make preparations to protect their young plants.

Care for your Golden Harvest flowers as they bloom by removing stems and leaves after they have turned yellow and brown and as soon as the flowers begin to fade. A 2-inch layer of mulch will prevent weeds and damage from cool or warm weather while the plant is still young. Water sparingly in between rains, and do not fertilize again until the fall.
