Tulips are long-day plants and cannot grow without sufficient light.If the environment is dark, the plant can not carry out photosynthesis to synthesize nutrients, so it will grow poorly, resulting in yellow leaves.At ordinary times, it should be placed in a sunny place, so that it can be exposed to light all day.If the light is too strong, it also needs to be properly shaded to avoid sunburn.
Tulips prefer a mild climate. If the temperature is too high, the water in the plant will be lost quickly, resulting in yellowing of the leaves.In this case, it needs to spray water properly to reduce its temperature by evaporating water and absorbing heat.In addition, good ventilation should be maintained, which can also accelerate evaporation and avoid too humid environment.
Tulip bulbs are more afraid of waterlogging, once too much water will appear rotten, and then affect the roots of the plant.Daily watering should not be too much, keep wet before germination, less water after emergence, and let the soil dry slightly when flowering.If too little water is given, the growth of the plant will slow down.
The growth of tulips needs fertilizer, and many nutrient deficiencies will lead to the phenomenon of yellow leaves, which generally requires timely fertilization.At the beginning of planting, sufficient base fertilizer should be applied, usually dry chicken manure or decomposed compost should be used, when the plants grow leaves, liquid fertilizer can be applied, and compound fertilizer should be applied every 7-10 days in the peak growing season.Fertilizer should be stopped at the flowering stage, and potassium dihydrogen phosphate should be applied after flowering.
