Plant flowers in spring, beware of cold spring, don't worry about these operations!
When the spring is warm and still cold, the most important thing is to pay attention to the cold spring. Many flowers survived the winter but died in the spring. The reason is that these things were done too early in the spring!
move indoor wintering potted plants out of the outdoors too early.
The winter climate in the north is cold and the temperature is low, so the southern flowers should be moved indoors for wintering. For example, high-temperature milan, poinsettia, African impatiens, begonias and prickly pear succulent flowers, plant pots should be placed on the indoor windowsill with sufficient sunlight and high temperature (between 20°C and 25°C), and the minimum temperature should not be low At 10°C. It likes moderate temperature jasmine, geranium, rose, and evergreen. The suitable temperature in winter is 18°C to 22°C, and the minimum temperature should not be lower than 6°C. Like low-temperature kumquats, osmanthus, orchids, the temperature in winter should be kept between 12℃ and 15℃, and the minimum temperature should not be lower than 2℃. For aquatic flowers such as lotus, water lily, eichhornia crassipes, and bungalow lotus, drain the water before frost and move the flower pot to the cellar or corridor. The temperature should be kept at 5°C. Water should be sprayed properly when the pot soil is dry.
These overwintering flowers cannot quickly adapt to the outdoor environment, and need an adaptation process. Generally, the overwintering flowers can be cultivated when the outdoor temperature reaches 7°C. Generally, the flowers are moved outdoors in the morning and the flowers are moved back home in the afternoon. Prevent low outdoor temperature at night and frost damage. Generally, wait until the average outdoor temperature rises above 10°C, that is, when the day and night temperature is between 10 and 20°C, the temperature basically rises around April. Of course, the average temperature is appropriate depending on the location, and the flowers can be kept outdoors. Up.
Water a lot of water too early
In spring, everything recovers, and the overwintering flowers are in a dormant state or slow growth stage. At this time, they have just sprouted and need to water the flowers. At this time, if you water a lot of water too early, the water in the pot soil will evaporate and absorb slowly, which will easily cause the branches and leaves to grow steeply. The pot soil will be wet for a long time, and the lack of oxygen will easily cause rotten roots, which will affect the later flowering and fruiting.
Therefore, spring watering is also adequate. See dry and wet, and the amount of watering can be gradually increased with the temperature and plant growth. In the dry weather in spring, you can spray water on the leaves with a watering can.
scientific top-dressing, not greedy for many
potted flowers are relatively weak after overwintering. Applying concentrated fertilizer in spring may cause burnt potted plants. It is recommended to use organic fertilizer and special compound fertilizer for potted plants. The frequency of fertilization is generally recommended to be applied every 10 to 15 days, and the amount of fertilization gradually increases. Pay attention to the point application of fertilization, and water and loosen the soil, which is conducive to root growth.
should be properly ventilated. Do not allow potted plants to be irrigated with cold breeze. Especially high-temperature flowers and green plants Milan, poinsettia, African impatiens, begonias, etc. It is recommended that the flowers be placed in a ventilated place at noon on a sunny day. As the temperature rises, gradually increase the number and time of window opening and adapt slowly.
