Maintenance method of succulents in summer (planting in summer)

Although succulents grow as usual in summer, we should also pay attention to avoid direct sunlight at noon, ensure ventilation and cooling in high temperature weather, and prevent water accumulation and root rot when watering. The following is uncle gardener's introduction to the summer conservation of summer plants and succulents. 1. illumination: in summer, we should give succulents plenty of sunshine. If the light is insufficient, plants will not only grow white, but also affect flowering. In particular, the succulent stems of cactus and succulent plants of Euphorbiaceae will suddenly become thinner due to insufficient light, which will affect the sense of modeling. Once it appears, it is difficult to restore the original state; For foliage succulents, the plant morphology is loose and the color of leaves is dim. Especially for some varieties with red leaves or patterns or white powder on their leaves, the fleshy leaves will turn green, and the patterns or white powder on the leaves will decrease or even disappear. Therefore, it is best to maintain plants in outdoor places with sufficient light and good ventilation; For some delicate varieties, it is necessary to avoid strong direct sunlight around noon from June to August to avoid strong light burning the epidermis. However, plants planted indoors or in other places with insufficient light for a long time should not be suddenly exposed to strong light. They should be kept in semi-shade for a period of time, and then moved to a place with strong light, so that they can gradually adapt to the environment. 2. Temperature: Although succulents like high temperature environment in summer, attention should be paid to ventilation and cooling when the temperature is higher than 38 in summer. For plants planted in the greenhouse, the plastic film around the greenhouse can be opened to facilitate ventilation and cooling, and the plastic film should still be left at the top to prevent rain, and the plastic film should be covered with a sunshade net to facilitate cooling. If conditions permit, you can also install a ventilator or electric fan in the greenhouse to strengthen ventilation and avoid plant rot caused by sultry humidity. For some valuable varieties, white or light-colored stones can be spread on the surface of the basin soil to reflect sunlight and avoid excessive heat absorption of the basin soil. 3. Watering: succulents in summer need relatively sufficient water during the growing period, otherwise they will stop growing and their appearance will change. When watering, avoid sprinkling on the leaves. If you want to fall into the soil, you should blow away the water droplets on the leaves in time. It is recommended to use a pressure watering can to avoid the above situation. You can do enough watering, but you can't accumulate water. Attention should be paid to drainage and waterlogging prevention in rainy season to avoid root rot caused by soil water accumulation. It should be pointed out that succulents in the growing period are drought-tolerant, but they don't like drought. If the growing season is short of water for a long time, the plant will not die, but the growth will be extremely slow or even stop, and the appearance will be poor. Therefore, we must give enough water during the growth period. The watering time is better in the morning or evening, but it should be avoided when it is hot at noon. 4. Fertilization: Different from other dormant succulents, succulents in summer can apply decomposed dilute liquid fertilizer or "low nitrogen, high phosphorus and potassium" compound fertilizer every 10 ~ 15 days according to different varieties in the growing season. New plants should not be fertilized within one month, and plants with weak growth should not be fertilized. For most succulents, fertilizer can be applied once every half a month, and slow-growing varieties can also be applied once a month. Some extremely slow-growing varieties don't even need fertilization. Don't water for a few days before fertilization. After the basin soil is basically dry, loosen the soil the day before and apply fertilizer the next day to facilitate the absorption of plant roots. Because the osmotic pressure of the roots of most succulents is very low except some varieties such as cactus, the concentration of fertilizer must not be too high. The types of fertilizers vary with the varieties and growth stages of plants. Generally, the amount of nitrogen fertilizer applied to succulent plants with green leaves at seedling stage can be slightly higher, and phosphorus and potassium fertilizer should be applied to spherical and columnar plants and red, yellow or other non-green plants at flower bud differentiation stage and flowering and fruiting stage, and phosphorus and potassium fertilizer should be applied to succulent plants with stems.

When applying fertilizer, be careful not to sprinkle fertilizer on plants. To plant flowers, ask uncle gardener!
