2. Water demand. The raw stone flower has strong drought tolerance and can grow under dry environmental conditions. Its roots are afraid of water stains. If there is water in the flowerpot, or watering and fertilizing too frequently, it is easy to cause root rot. The principle of fertilizing and watering it is "dry and wet alternately, dry thoroughly, no watering, and drenching thoroughly". When fertilizing and watering it, it is necessary to avoid wetting the plant during the day.
3. Temperature requirements. Raw stone flowers like sunshine, so they should be cultivated in Nanyang terrace or windowsill in spring and autumn. The optimum growth temperature of raw stone flower is 15℃ ~ 25℃, and it is afraid of high temperature and sultry, and it goes into dormancy when the temperature is above 33℃ in summer. Avoid cold cream. The overwintering temperature should be kept above 65438 00℃. In winter, when the temperature drops below 7℃, it will go into hibernation. If the ambient temperature is close to 4℃, it will freeze to death.
4. Disease prevention. The harm of leaf spot and leaf rot mainly occurs on raw stone flowers, and 65% zineb wettable powder can be sprayed 600 times. Insect pests do great harm to ants and root-knot nematodes, so soil replacement method is adopted to reduce the harm of nematodes. To prevent ants, you can use pots to protect them from water, so that ants can't climb on the delicate and juicy spherical leaves.

breeding method
sow seeds
Sowing is a common propagation method of Quercus plants. Raw stone flowers are usually planted in April-May in spring. Because the seeds are small, they are usually potted indoors. After sowing, they don't need to be covered with soil, otherwise they can't germinate. When the soil in the pot is dry, you should water it by soaking the pot instead of directly watering it to avoid washing away the seeds. Sowing temperature is 15-25℃.
Germinate about half a month after sowing, and let the seedlings gradually see the light after emergence. The seedlings are only the size of soybeans and grow very slowly, so management must be cautious. Generally, water is poured once every 3-5 days after growth, and it takes 2-3 years for the seedlings to bloom. ?
Factory division
Every spring, the original stone flower will grow new fleshy leaves from the gap in the middle, break the old leaves and die with atrophy. New leaves grow rapidly, shrink and crack in summer, and 2-3 new tender plants grow from gaps, which can be cut off from the base and planted.
