Rhododendron likes bright scattering light, so it should be placed in a good place for indoor maintenance, such as study, living room and other places. If it needs to be properly shaded in the outdoor maintenance in summer to avoid direct sunlight, you can pull a sunscreen or cover it with something
Rhododendron root system is shallow and very fine. When watering, it must be noted not to pour too much water to prevent water in the basin from causing rotten root. Usually, it's OK to water the basin soil when it's slightly dry. In addition to normal watering when the temperature is high in summer, you can also spray water on the leaves and around it with a watering can. Don't spray on flowers when spraying water. Once you spray on flowers, it will shorten the flowering period.
Rhododendron likes acid soil, which can be mixed with saprophytic soil, garden soil and pine needles in the proportion of 5:2:3. Usually, if tap water is used for watering, it's better to air it at room temperature for one or two days, and then use it after the chlorine in the water evaporates. Especially the North flower friends, because the soil is more alkaline, so when watering can be mixed with a little vinegar or ferrous sulfate, can improve the pH of the soil
Rhododendron will stop growing if the temperature is lower than 5 ℃ in winter and enter a short dormancy period if the temperature is higher than 30 ℃ in summer.
In order to make Rhododendron blossom more vigorously, we should apply more fertilizer in the spring and autumn growth period. We can use the peel fertilizer and soybean residue fertilizer made by ourselves. Spray a little potassium dihydrogen phosphate before flowering, but stop fertilizing when the temperature is too high or too low.
When watering, be sure to keep the basin soil slightly wet. Do not pour too much or too little. Spring and autumn fertilization should pay attention to thin fertilizer, do not give it heavy fertilizer and raw fertilizer, it is easy to burn roots.
