How to hydroponically culture and care for tulips?
Tulips, also known as "wild lotus," "dry lotus," "grass musk," "fragrant tulip," "red and blue flowers," and "purple incense," belong to the genus Tulipa in the lily family. Tulips are perennial herbaceous plants with flat conical or flat oval bulbs, about 2 cm long. The tulip stem is about 6-10 cm tall, with a single flower at the top of the stem, large, upright, and forest-like, often with a black-purple base. Flower shapes include cup-shaped, bowl-shaped, ovate, and spherical, with single and double petals. Flower colors range from white, pink, magenta, purple, brown, yellow, orange, etc., varying in depth. The blooming period of tulips is usually from March to May, with an optimal growth and flowering temperature of 15-20°C. Tulips are long-day flowering plants that prefer a warm and humid climate in winter and a cool and dry climate in summer.
1. Hydroponic method
(1) The key to hydroponic culture of tulip cut flowers is to choose healthy and disease-free bulbs.
(2) Prepare a watertight tray, place the tulip in the tray, and maintain a rooting temperature of 8°C with humidity between 60% and 70%.
(3) After about 2 weeks, when the tulip roots are more than 3 cm long, move the tray to a greenhouse. Keep the temperature between 15-20°C and humidity between 60-70%, and add nutrient solution. The image shown is a hydroponically grown tulip.
2. Care guide
(1) Light Tulips enjoy sunlight. Insufficient light will cause poor plant growth, leading to bud drop, weakened plants, faded flower colors, and shortened blooming periods. However, for the first half-month after hydroponic culture, shading is needed to facilitate new root development, and after seedlings emerge, appropriate sunlight should be increased to promote bud formation and coloring. Once the buds are colored, direct sunlight should be avoided to extend the blooming time.
(2) Fertilization depends on the growth condition of the tulips, applying foliar fertilizer to balance vegetative and reproductive growth.
(3) Water change During the growth of tulips, a layer of oil film may form on the surface of the tray water, affecting normal growth and causing the roots to turn brown. Therefore, water change should be performed 2-3 times as needed.
Hydroponically grown tulips can be divided into three stages from bulb rooting to flowering: the germination stage, the vegetative growth stage, and the flowering stage.
① Germination stage management. Fill the pot containing bulbs with tap water, completely submerging the roots. Place the pot in a well-lit indoor area (best on a windowsill), maintaining an indoor temperature of about 13°C. Roots and sprouts can be seen in 4-7 days, then entering the vegetative growth stage.
② Vegetative growth stage management. During the growth period, tulips grow very fast and require a lot of water, keeping the pot water constantly submerging the roots. The optimal growth temperature is 15-18°C, and it should not exceed 25°C. Low temperatures will delay flowering, and high temperatures will cause etiolation. Due to the phototropism of the plant, to keep the flowers growing upright, the pot direction needs to be frequently rotated. After 2-3 weeks of growth, when the number of leaves reaches 3-4, the flower bud appears at the top of the stem, entering the flowering stage.
③ Flowering stage management. For tulips entering the flowering stage, maintain the growth temperature at 15-18°C, and within 5-7 days, the flower bud will open, displaying bright and colorful flowers. After flowering, to extend the blooming period, it is best to move the pot to a cool indoor area, with a general flowering period of 2-3 weeks.
