Kalanchoe black rot in summer? One sentence plus one ingredient for a safe summer, and flowers bursting in winter

The thick, fleshy stems and leaves of Kalanchoe store water; the water-rich fleshy stems, when kept for a long time in very moist potting soil, rot easily. Black rot is a major hurdle for Kalanchoe getting through summer. To prevent black rot in Kalanchoe, remember one sentence, add 1 ingredient, get through summer safely, and in winter the flowers bloom till they burst!

This 1 sentence is: shade, cool down, control water, short daylight.

Shade

Kalanchoe is a plant that likes cool conditions and fears heat; in the peak heat of midsummer it goes dormant, so in summer we generally provide shade. We can put Kalanchoe on a north balcony or behind large plants; these methods all make Kalanchoe leaves greener and its growth better. On the contrary, if you put Kalanchoe directly on a south balcony without shading, the result is mostly that the leaves are sun-scorched grayish white, the leaves become thinner, and the plant barely survives.

Cool down

To cool down, you can spray water on the ground; as the water evaporates it carries away some heat. You can also spray water on the leaves, but with this method you must control the amount of water well, because excessive spraying easily causes the plant to rot. Add a shade net to reduce sunlight and lower the temperature.

Control water

When Kalanchoe gets infected with black rot, an important trigger is potting soil that is too moist, which causes the thick fleshy stems of Kalanchoe to rot. In summer's high temperatures, for any plant, watering and fertilizing must change relatively. Controlling water does not mean not watering, but watering less and watering moderately.

Short daylight

Summer light is very strong; too much sun makes Kalanchoe go fully dormant and not grow new shoots, or dries out the new shoots, so it blooms less in winter. In summer, do shade treatment in time, or during periods of stronger light, move the plant to an environment with weaker light.

Add 1 ingredient

Add 1 ingredient to the potting soil of Kalanchoe to reduce the chance of black rot occurring. This thing is plant ash; plant ash can absorb moisture and prevent rot and pests. Sprinkle a ring of plant ash around the edge of the Kalanchoe pot (when placing it, do not get it near the roots of the Kalanchoe), and it can effectively prevent black rot in Kalanchoe.

Seeing this, do flower lovers now know how to grow Kalanchoe in summer? One sentence: shade, cool down, control water, short daylight. Add 1 more ingredient, and Kalanchoe gets through summer safely, its branches grow rapidly, and in winter it blooms till it bursts.
