Corn stone cultivation method
The succulent plant cornstone is very popular among gardening enthusiasts for its unique purple-red leaves, but how to properly maintain it to show its most beautiful posture? This article provides you with a detailed analysis of indoor cultivation techniques from temperature control to pest control. 1. Key points of temperature control for cornstone growth environment management Cornstone has the characteristics of-5℃ cold resistance, but it is recommended to move it indoors for maintenance in winter. The optimal growth temperature band is 18-25℃. When the temperature exceeds 30℃, ventilation needs to be strengthened, and watering frequency should be reduced below 5℃. The temperature difference between day and night in spring and autumn can promote leaf color development, and avoid close to glass windows in winter to prevent frost damage. The scientific watering system adopts the "see dry and wet" method. It is watered thoroughly every 10-15 days in spring and autumn, and the high temperature period in summer is shortened to 7 days but the amount of water per time is reduced. During the winter hibernation period, you can replenish water with a small amount every month. Use a pointed spout to slowly inject water along the edge of the basin to avoid water in the leaf center. It is recommended to add 30% perlite to the soil to enhance drainage. 2. Advanced techniques for cornstone maintenance Light and color management 4-6 hours of scattered light a day can maintain a compact plant type. Direct light in the morning will help the leaves appear purple-red markings. In summer, a sunshade net is needed to filter the strong light. When the light is insufficient, a fill light can be used to fill the light for 2 hours a day. The distance from the plant is 40cm to avoid burns. Nutrient supply plan Corn stone cultivation method
During the growth period (March to June, September to November), a meaty special fertilizer diluted 2000 times is applied every month, and bone meal is applied quarterly to supplement calcium. Avoid using high-nitrogen fertilizers. Choose slow-release fertilizers with an N-P-K ratio of 5-10-10, and ensure light within 24 hours after fertilization. 3. Propagation and modeling management Cutting propagation steps Select a healthy terminal bud of 5-7cm, dry the incision for 3 days, insert it into a vermiculite substrate, maintain the micro-moisture of the substrate, and create roots in an environment of 15-25℃ for about 20 years. Plant breeding should be carried out during pot changes in spring, retaining 3-5 main roots in each group, soaking them in carbendazim and placing them in pots. Modeling and pruning method The long branches retain 1-2 pairs of leaves at the base, and 2-3 new buds will germinate at the incision. The overall shaping is carried out every spring, and the principle of "removing the strong and retaining the weak" is adopted to maintain the balance of the plant type. Trim tools need to be disinfected with alcohol, and wounds should be kept away from water. 4. Dealing with common problems and pest control
