1、 Selection of cultivated soil
The selection of soil is an important step in the cultivation process. However, it should be noted that different types of primroses have different soil types. If it is a cold greenhouse, such as "e Baochun", "Tibetan Baochun" and other varieties, it is best to use neutral soil. If it is a variety used for flower bed layout, such as "Primula", it needs to use soil with good drainage and more humus. However, do not use acidic soil for all varieties p>
2、 How to cultivate
Generally, shallow pots or wooden boxes are used as containers for sowing. The plant spacing is about two centimeters. After sowing, put them in a warm and semi cloudy environment, water them in time, keep the flower soil slightly wet, and the seedlings will emerge soon. After that, transplant them into a small basin with a diameter of about eight centimeters, and then move them into a slightly larger basin with a diameter of about twelve centimeters. When transplanting, pay attention to the depth of planting, not too deep or too shallow. If it is too deep, the roots of the plant are easy to rot. If it is too shallow, it will not be firmly rooted, and it is easy to fall down when the wind blows p>
3、 Precautions
After cultivation, pay attention to the appropriate supplement of fertilizer. Don't water too much, especially don't let water accumulate in the flower soil. The light should also be appropriate, and shade must be provided in summer p>
