Input (English): [header] How to prevent hyacinth flowers from flopping [title] Choose a location with good light to plant your bulbs. [step] Hyacinths need about 5 hours of light each day in order for the stems to grow strong. In weak light, the stems will be thin and the blooms will easily snap the stalk. <sep> (A) In strong light, the flowers will not flourish if they are exposed to wind and/or frost. For optimal plant growth, choose an area with open space with full sun and partial shade. (B) On the other hand, in strong light, the stems will take light directly from the bulb, and the bloom will use less energy. [substeps] Fluorescent lights don't have to be fluorescent. (C) [title] Plant hyacinth bulbs 4 inches (10 cm) deep. [step] If the bulbs aren't planted deep enough, the plant's stem won't have enough strength to support the weight of the flowers when the hyacinth blooms. (D) Aim for a spot that receives at least two hours of sunlight a day. [substeps] In good, semi-shade, mild weather conditions, such as april-april or july-august will provide a deep, rich, full-colored hyacinth flower.
