Generally speaking, the basin is suitable for tile basin, and those with underground holes should be used, so that the ventilation effect is better. Because the roots of Rhododendron are relatively shallow and grow very slowly, you can choose some smaller basins, so that when watering the seeds, it will not waste, and it will be more conducive to its growth. The soil in the basin should choose some acid soil with loose texture and good drainage. When filling the basin soil, you should pay attention to using some coarse soil below and some fine soil above.
Rhododendron generally prefer wet places, not too dry. You can water it a little more when it blooms. By the time of winter, it has entered the period of dormancy, so it does not need a lot of water at this time. Generally, it can be operated once every 4 to 5 days, and it is better to water around noon in sunny and warm days. The specific amount of watering depends on the drying of the soil in the basin. If possible, you can use the water collected when it rains, or the river water or pond water. If it's tap water, it's better to store the water for a day or two. In the growing season, water it once a week.
Rhododendron's preference for fertilizer is generally based on the rotten fish meal and broad bean, which are then watered with some water after being rotted. Never use human urine. Wait until its flower bud comes out, every 10 days or so, you can apply a thin fertilizer to it, a total of 2 to 3 times, so that the child can promote the old leaves to turn green slowly and sprout new roots. After the flower falls, in order to make it better send out new branches and grow new leaves, it is necessary to fertilize it 5 to 6 times between May and July. If it rains continuously, a little dry fertilizer can be applied. And when it's about to stop growing, apply fertilizer 1 or 2 times more.
