Rhododendron flowers cut into the pot should be on the pot. The pots with the best perforated mud pots were the best, followed by the purple sand pots, and the glaze pots and porcelain pots were the worst. The pot should pay attention to the size of the selection of pots, should not use small pots. If the basin is too large, basin soil will not last long, ventilation will not be good, and the root system is not easy to reach the basin wall, affecting the development of seedlings. The general cutting seedlings can be used to select mud pots with a diameter of about 10 cm, and then one year later, turn them into pots with 15 cm left. When putting on the basin, you should pay attention to the drainage layer. Cover the drain hole with tiles first, then add 1/3 of coarse soil particles, and add a little fine soil. Then put the rhododendron seedlings in one hand to straighten the seedlings and fill the pots with one hand. Pay attention to fill only 2 cm below the pot mouth, not too full, so that watering in the future, and finally approved the pot around, shake the flower pot, so that the pot surface formation. After planting, use a watering can to pour water once. Note that when water is boiled, water must be poured to the bottom of the basin to seep out. If the water is not permeated, only wet and damp layers will not wet the inner layer, which will make the pot flowers dry.
There are two kinds of azaleas that need to be turned over. The first is that the seedlings grow up and the root system is full of potted soil. It is necessary to expand the range of the Genkang extension. Usually should pay attention to the pelvic floor drainage hole has no root outstretched, if there is on the race to turn pots, the plants from the small basin into the large basin. Second, after 2-3 years of potted plant growth, the pots and soils will be depleted. In order to supplement the nutrients and improve the soil, it is necessary to replace the potted soil.
Rhododendrons usually turn over after climbing flowers, or before the autumn buds. When removing the pot, remove some of the soil and pay attention to repairing the roots with scissors. Old roots are roots that grow poorly and are black and dry. But be careful: when the seedlings are turned over, they cannot be rooted. When the plants are turned over, it should be noted that the roots should have earth balls. After a good pot, it should also be noted that the first watering should be thorough, and let it be done in the next few days. If you are too wet, the root cuts will rot. It usually takes a long time until the new root grows. If you turn over the pot in the fall, it is best done in October. Although the azaleas are cool, they should pay attention to keeping warm after overturning. If you do not have a greenhouse, you can use a small shed in a sunny, south-facing area and cover it with a plastic membrane for safe wintering. Rhododendron lanceolata, generally small seedlings are turned once a year, and the rhododendrons are turned over once every 2-3 years.
