When raising geranium, we should try our best to use soil with high nutrient content and not easy to harden. We should also turn over the flower soil in time to increase the air content. If you don't know how to make it, you can prepare three parts of garden soil, four parts of rotten leaf soil, two parts of perlite and one part of base fertilizer, mix them together and use them as its flower soil.
Water it properly, not too much, because too much water will affect its normal growth. Usually water as long as the soil is wet, do not let water in the soil. In addition, when it rains, you can let it rain properly, but after the rain stops, you should timely drain the rainwater accumulated in the basin.
It needs to be fertilized mainly in spring and autumn. It can be diluted once every 7-10 days during these two times. In winter, because it doesn't grow very well, the number of fertilization should be reduced accordingly. In the summer when the high temperature, it will grow temporarily, so we should also stop fertilizing them.
If the breed is a relatively high variety, and you don't want to make it grow very high, you can spray some chlorpromazine when it grows to 12-15cm. So it won't grow very high
