How often to water rhododendron
A comprehensive explanation of how often to water rhododendrons and the correct care methods for rhododendrons in the aspect of green plants and flowers, followed by a complete introduction.
rhododendron is a plant with a large number of flowers and a relatively long blooming period. During the maintenance process, it prefers moist potting soil to keep the soil moist, which can make it grow better. Many people know this, but they think that the so-called moist potting soil means to water it frequently, keeping the soil in a wet state, sometimes even in a water-logged state, which causes problems with the rhododendrons we raise, such as black leaves, rotting leaves, and rotting roots. In fact, watering rhododendrons is very crucial.
We often see articles online that say rhododendrons should be watered every few days in a certain season, but this is not reliable because everyone's region, the general environment for maintenance, and the potting soil mixture are different. If you water it and it dries up in one day in other places, but it doesn't dry up in 10 days in your place, is it suitable to follow the same watering frequency? So don't follow this watering method. Rhododendrons prefer moist soil; we should not water them immediately when the soil surface is slightly dry. This is wrong because when we find the soil surface dry, the inside is actually still moist, and there's no need to water. The most correct watering method is to stick your finger into the surface of the potting soil when you want to water, dig down two to three centimeters, and if you feel no moisture, it means the bottom is still damp. Water it thoroughly to keep it in a moist state. This way of watering will not cause problems. If the soil surface is just dry or still wet and you feel it's short of water, then watering will only lead to soil waterlogging and cause root rot, and rotting leaves or black leaves are caused in the same way.
As long as the rhododendron grows normally and blooms normally, this watering method is very universal. You will not have problems if you follow it. However, during the maintenance of rhododendrons, you must ensure good ventilation when watering and give it some light. This way, after watering, the moisture in the potting soil can evaporate quickly, preventing the soil from being waterlogged and avoiding root and leaf rot. Good ventilation is the key to growing rhododendrons well.
Actually, rhododendrons are not difficult to grow. The key reason why they have problems is watering. Once the watering is mastered, we should prepare well-ventilated soil, supplement fertilizer regularly during the growing season with multi-element fertilizers to let it grow balanced, and supplement phosphorus and potassium fertilizers in advance during the blooming season to promote flowering. Stop using phosphorus and potassium fertilizers when the flower buds are about to open. In this way, if we give it some scattered light, the rhododendrons we raise will not have problems. But there is one thing to remember, if you are in the north, where the potting soil and water are alkaline, you should regularly water it with ferrous sulfate solution to prevent soil alkalinity and prevent the new leaves from turning yellow.
