There is a great possibility that the leaves of Strelitzia are cracked because the wind is too strong. Hewanglan is actually a kind of "delicate" flower. It likes the light, but the light is too much and too strong. He can't eat it. He likes the water, but the water can't be too much. In a word, it needs the right amount, everything needs the right amount. Moreover, Hewanglan is pollinated by hummingbirds in Africa of origin. After it is introduced into China, it can only be pollinated artificially. There is no help from the wind during this period, so try to put the crane orchid in the shelter.
The discomfort of other parts of the plant will be reflected in the leaves of the plant. If the root system of the plant is injured, it will affect the absorption of nutrients and water by the root system of the plant, resulting in the yellow leaves. Second, there are many reasons for the root system injury, such as too much water and too much fertilizer. So, once the root system is injured, prepare to change a basin for Strelitzia regia!
The soil nutrients in the flowerpot are too little, in short, the fertilization is too little, the Strelitzia is lack of necessary nutrients for growth, so the page turns yellow.
The solution is to fertilize Hewanglan in time. Remember to use thin fertilizer for many things, rather than too much at one time!
Another reason is that the pH of the soil is not appropriate, it is likely that the soil is slightly alkaline. In the alkaline soil, the new leaves of Strelitzia are very easy to turn yellow.
The solution is to adjust the pH of the soil, or change the pot directly.
Although it likes light, it should not be exposed to the sun, so in summer, its leaves will turn yellow in the sun. Therefore, it should be placed in the shade to receive the light of astigmatism.
