It can be made by mixing 2 parts of humus soil, 3 parts of coarse river sand or vermiculite, and adding a small amount of bone powder as base fertilizer and bactericidal drugs such as bactericidal spirit and thiophanate methyl. It can also be planted with synthetic materials such as ruby soil and fairy soil. The effect is good, but the production cost is high.
In addition, we should pay attention to changing soil regularly, in autumn. When changing pots, take the plants out of the soil, shake off the soil at the roots and try not to hurt the capillary roots. Cut dry old roots and rotten roots, and then plant them with new culture soil.

breeding method
Sowing is a common propagation method of Quercus plants. Raw stone flowers are usually sown in April-May in spring. Because the seeds are small, indoor potted plants are generally used for sowing. It is not necessary to cover the soil after sowing, otherwise it will not germinate.
When the soil in the basin is dry, it is necessary to water it by soaking the basin. Don't water directly, so as not to wash away the seeds. Sowing temperature is 15-25℃. Germinate about half a month after sowing. After emergence, let the seedlings gradually see the light. The seedlings are only the size of soybeans and grow very slowly. Management must be cautious. Water every 3-5 days after growth, and it takes 2-3 years for the seedlings to blossom. ?
February to April in spring is the molting period of this genus. At this time, fertilization should be stopped and watering should be controlled to make the original old skin dry as soon as possible.
