Tulip reblooming capability
An in-depth explanation for netizens about how tulips rebloom and cultivation methods to improve the reblooming rate, related topics in flower cultivation. Next, the editor will introduce to the netizens.
I have been focusing on flower cultivation for more than ten years and have rich gardening experience. First, I have to brutally tell the truth, the chance of tulips reblooming is indeed small, or the quality of reblooming is getting worse each time. Why? Keep reading. The original habitat of tulips is on the Mediterranean coast, where the local climate is characterized by wet and cold winters and dry and hot summers. After the tulips have withered, they can make use of the harsh local climate conditions (which are harsh for humans but ideal for tulips) to maintain green leaves with enough cool temperatures before the arrival of high summer temperatures. By the time high temperatures come, the underground bulbs have already grown large enough, and after harvesting, they can bloom normally the following year.
The life cycle of tulips repeats year after year. But what about in China? Shortly after the flowers wither, by May the temperature starts to rise rapidly (just like this stage now). At this time, the underground bulbs of tulips have not yet grown to a sufficient size. However, since tulips are heat-sensitive, they have to enter a dormant period to survive at this point, which is manifested by the withering of stems and leaves. This is why every year the bulbs we dig out after the tulips go dormant are much smaller than the commercial bulbs we bought. Such bulbs have little hope of reblooming, and even if they can, the quality of the blooms will be greatly reduced, which is a phenomenon of plant degeneration. Moreover, China's climate is hot and rainy in summer, which is very fatal for the bulbs of tulips in the dormant period, as such climatic conditions easily lead to bulb rot.
Although degeneration is inevitable, if you want to try it yourself to minimize the degeneration of tulips the second year, I suggest you can start from the following four aspects. First, pruning. It is well known that plants need to consume a lot of water and nutrients to bloom, so after the flowers wither, you should cut off the残花 (withered flowers) of tulips promptly. The position of the cut should not be too low, just below the flower bud part is fine. This can prevent it from consuming nutrients by forming seeds and also retain the lower leaves to the maximum extent, which can produce more nutrients to supply the bulb growth and expansion.
Second, temperature control. Tulips prefer a cooler environment, so after the flowers wither, they should be placed in a location without direct sunlight. But don't keep them in a dark room, as sufficient diffused light is still necessary to minimize the temperature of their surrounding environment as much as possible.
Third, fertilization. Generally speaking, the bulbs of bulbous flowers enter the expansion period after flowering. At this time, a large amount of potassium fertilizer should be applied. It is recommended to use a spray and drenching combination of monopotassium phosphate at a concentration of 1000-2000 times, once every 7 to 10 days, until the above-ground part of the plant withers completely.
Fourth, watering. Watering during the bulb expansion period should be cautious. As I mentioned earlier, tulips are not adapted to our country's climate, and high summer humidity easily leads to rot. Therefore, watering should be done when the soil is dry, and it's okay if it's a bit dry. If you really can't judge the timing of watering, just use your hand to feel. If the soil below the surface is dry for about two centimeters, you can water, and water thoroughly, which means watering until water flows out from the bottom of the flowerpot. These four methods can only minimize the degree of degeneration of tulips and cannot fundamentally reverse the trend of degeneration year by year. Therefore, for Chinese flower enthusiasts, if you want to see the perfect blooming of tulips every year, you can only buy new bulbs every year, which is not expensive.
