The most suitable temperature for the growth of Florist Kalanchoe is between 15 ℃ and 25 ℃. Once the temperature exceeds 30 ℃ in summer, the growth of the plant will be blocked and start to enter the dormancy state.
If you raise a long-lived environment, the temperature is more than 30 ℃, please maintain it strictly according to the following requirements, otherwise the plant will easily black rot, or even annihilate the whole army!
In summer, we must strictly control the amount of water in order to raise Florist Kalanchoe. At ordinary times, we can watch the leaves at the bottom of the plant wilt and feel the leaves become thinner. Then we can water Florist Kalanchoe.
If you want to have a long life in summer, you should pay attention not to expose yourself to the sun. Otherwise, when you are exposed to the rain and the sun, you are particularly prone to black rot. you'd better put it indoors for maintenance, or pull a sunscreen outdoors.
The pot is big, the seedlings are small, the water is over watered, the water can't spread out in the soil, plus the environment is not ventilated, the longevity flower will be black rot, so in summer, we must pay attention to ventilation.
If the leaves of longevity flower are dense, it is better to remove some leaves from the bottom of the plant, otherwise the plant itself will affect the ventilation, and it is easy to cause black rot.
The flower above is the maintenance method of longevity flower in summer. For the longevity that has already suffered from black rot, we can trim the healthy stems and leaves of the plants and reproduce them by cutting.
The black rot usually starts from the stem, so we can cut the top of the long-lived branch, 5-8cm long healthy branch, the lower part of which is inclined to cut, and the upper part leaves 1-2 pairs of healthy leaves.
Put the pruned branches on the windowsill with half shade ventilation, air them for 1-2 days, then cut them in the damp soil, and put them in the cool room with half shade to wait for rooting.
In summer, the biggest fear of longevity is high temperature. Flower friends with conditions can put Florist Kalanchoe in the air-conditioning room for maintenance. When the soil is dry and watered, longevity can continue to grow.
But in the air-conditioned room, although it can grow as usual, it is also easy to grow in vain, so we should pay attention to that before 10 a.m. and after 3 p.m., we should put it in the Nanyang terrace for sun exposure.
As for longevity, as long as we survive to the end of August, we will win. However, in the summer, huayitu, who is kept in the air-conditioned room, will trim the ugly branches in autumn.
Note: some flower lovers buy longevity in spring and summer. Due to the regulation of flowering period, the plant is still blooming. If the curing temperature is over 30 ℃, it is recommended to cut off the flower and two pairs of leaves under the flower immediately to reduce the plant's own consumption.
