What if the leaves of Paeonia lactiflora turn yellow
1. Soil drought
We know that the soil that a plant needs is ventilated and loose, and if we give it flowers in very dry soil, it will have a great impact on it, because the development of the root will be more difficult, and it is easy to be harmed, and its ability to absorb water is not high. Once under the condition of high temperature, because its leaves transpirate greatly, they will lose a lot of water, so the leaves will turn yellow. So we have to change it to a more loose kind of soil.
two。 Improper fertilization
Because fertilization is so that it can absorb a variety of elements, but if we apply too much nitrogen fertilizer, it will cause its leaves to curl up and turn yellow. In particular, it lacks elements such as iron and manganese, and this kind of thing will be more serious. So we need to apply compound fertilizer to it, not too much nitrogen.
3. Pruning too early
Because plants need pruning and topping, if we do this too early, it is very likely that its phosphorus will be difficult to transport, so it will accumulate leaves below, while leaves in other places are likely to turn yellow. Therefore, do not prune prematurely, if you accidentally cut it early, remove its yellowing leaves and maintain them slowly.
4. Too much watering
Because it is afraid of waterlogging, if it is watered too much, it is easy to cause its leaves to turn yellow, especially if there is stagnant water, its roots are easy to rot. If there is too much water, you can put it in a cool and windy place, so that it can disperse the water.
