A Detailed Guide to the Characteristics, Cultivation and Care of Tulips
The tulip is a perennial bulbous flower of the genus Tulipa in the lily family (Liliaceae). Beloved for its goblet-shaped blooms and vivid colors, it is one of the world's best-known spring ornamental flowers. It prefers a cool climate, growing and blooming in winter and spring, while in summer, when temperatures are high, its above-ground parts wither and it enters dormancy, surviving the summer by means of its underground bulb.
The tulip originated in Central Asia and along the Mediterranean coast, and was later widely introduced; today it is cultivated on a large scale in many regions. Its horticultural varieties are extremely rich, with flower colors spanning red, yellow, pink, white, purple and various bicolors. By flowering period they can be roughly divided into early-, mid- and late-flowering types, and flower forms also vary widely, including cup-shaped, bowl-shaped and lily-flowered.
When cultivating tulips, the bulbs are generally planted in autumn, and a loose, fertile, well-drained sandy loam in a spot with ample light is preferable. The bulbs need a period of low winter temperatures for vernalization before they can flower normally the following spring, so in regions with warm winters the bulbs often need cold treatment before planting. During the growing period, keeping the soil slightly moist is sufficient; overwatering easily causes the bulbs to rot. After flowering, spent flowers should be cut off promptly, and once the leaves have naturally turned yellow and withered, the bulbs should be lifted and stored in a cool, ventilated place.
The main problems encountered in cultivation are failure to bloom and bulb rot, which are mostly related to insufficient cold accumulation, waterlogged soil or poor bulb quality; when buying, choose plump, firm bulbs. It should be noted that the sap of tulips may cause skin allergies in some people, and the bulbs are not edible; when grown at home, they are best kept for ornamental purposes.
