How to grow tulips
For tulip planting, it is necessary to choose mature, firm, solid-textured, intact, high-quality bulbs with no disease or insect spots. The cultivation soil should be fertile, loose and well-drained. It should be kept slightly acidic (PH6-8.5). Avoid alkaline soil and heavy soil. Plants must be rotated with other crops. Potted plants should be replaced with cultivation soil every year. Tulips, like fertilization, can be used as a mixed base fertilizer with rotten leaves, rotten cake and bone meal, and used as a top dressing during the growing season.
Tulips like sunlight, the ground should be exposed to sunlight, and potted plants can be placed in a sunny room. The suitable growth and flowering temperature is 15-20°C, the summer dormancy period requires between 20-25°C, and in winter it should not be lower than 5°C.
Tulips are planted from October to November. After planting, water once, and cover with straw in winter to prevent freezing. After the spring sprouts emerge from the soil in early spring, normal management is carried out. Apply decomposed thin cake fertilizer once every 7 to 10 days, and apply some phosphorus and potassium fertilizer before budding to promote earlier flowering. Usually keep the soil moist, but there should be no standing water; after flowering the soil should be kept dry, not wet, to favor the swelling of the new bulb and the formation and growth of the bulb.
In mid-to-late June, the aboveground part of the plant is all yellow, the new bulb in the underground part matures, and the daughter bulbs form and grow to a certain size. At this time, the soil can be dug up, dried, and after mud coating stored in a ventilated and dry place. It needs to be between 20 and 25°C, and the higher should not exceed 30°C. When collecting, care should be taken to prevent damage to the fibrous membranous skin of the bulb and the surrounding root primordia of the horseshoe-shaped bulb, which is highly sensitive to pathogens.
Most of the factors causing tulip degeneration come from pests and diseases. In planting and management, the soil should be loosened frequently. Use herbicide drugs to spray toxic insects. If pests such as whiteflies, mites and worms are found, dimethoate and malathion can be sprayed. For underground nematodes, 80% dichloropropane (1:150) can be diluted with water and sprayed on the cultivation soil to kill them, but it should be done two weeks before planting.
In early spring, if it is rainy or the soil viscosity is too heavy, it is prone to disease. Usually, the yellow-brown lesions on the bulb gradually enlarge and turn black and shrink, and the plant will fall and die; this is caused by imperfect fungi among the fungi. After diseased plants are found, immediately remove and concentrate them and burn them. Mix pentachloronitrobenzene with fine soil (1:25) and take it out from the plants for control. Symptoms such as stripes and spots caused by pathogens on leaves and flowers can be controlled by spraying 1:1:100 Bordeaux mixture and 50% antibacterial 1000-fold solution.
