How to raise eight Immortals well

Eight Immortals, also known as Hydrangea, Yin Hydrangea. It is appropriate to change the basin once a year in early spring and add new culture soil (rotten leaf soil, garden soil and a small amount of sandy soil). When changing the basin, remove some of the old soil and rotten roots, and trim them properly. The eight Immortals like fertilizer, and during the period of growth and development, the mature thin liquid fertilizer is generally applied every half a month. In order to keep the basin soil acidic, 100 grams of ferrous sulfate can be added to every 50 kg of liquid fertilizer for watering. When 1 Mel potassium dihydrogen phosphate solution was added during the bud period, the flowers were bright in color. The leaves of Baxian flower are larger and require more water. In addition to the low temperature in winter, the amount of water should be strictly controlled, and the watering in spring, summer and autumn should be sufficient to keep the basin soil moist, especially in hot summer. From May to the end of August, it is necessary to spray water on the leaves once a day or every other day. As the eight Immortals are fleshy roots, too much water is easy to rot roots, so watering should not be excessive. Pour out the stagnant water in the basin in time after the rain. After September, the weather is getting cooler, it is necessary to gradually reduce the amount of water, so that the branches grow strong, in order to facilitate winter dormancy. Frosts Descent moved into the room and kept the room temperature at about 5 ℃ to promote its dormancy. The leaves should be removed before the beginning of winter to avoid rotten leaves. From the middle of December, it gradually moved to the sunny place, and the temperature rose to 15 ℃-20 ℃, which promoted the growth of branches and leaves, and Grain Rain came out of the room the next year. Because the flower head of the eight Immortals is too large, a bracket should be set up in time, so that it can not only keep the flower plant erect, but also make the plant appear plump.
