What to do if there are black spots on the green radish

1. Keep warm in time

Reason: Due to the low temperature, the green radish is frozen, and black spots are prone to appear on the frozen leaves.

Solution: Pothos itself cannot grow in a low temperature environment, it must be kept at least above 10℃. So move indoors immediately after catching a cold so that you can keep warm effectively. If you have floor heating, don't put the flower pots on the ground, otherwise they will be burned. If the room temperature is not high enough, you can put it in a plastic bag to keep it warm.

2. Provide shade

Reason: Pothos prefers to grow in a shady environment, and sunlight can cause black spots to appear on the leaves.

Solution: In hot summer weather, provide shade for the green radish or move it to a semi-shaded place. It can accept scattered light occasionally, but cannot be exposed to strong light.

3. Ventilation and moisturizing

Reason: Poor air circulation can easily breed bacteria, and low oxygen content will also be detrimental to the breathing of the leaves of the green radish, causing black spots.

Solution: Move the green radish to a well-ventilated place. You can open windows for ventilation indoors as long as it is not winter. In winter, you need to cover the plants with plastic bags at noon and poke a few holes in the bags to prevent the plants from being frozen by low temperatures. In addition, watering the leaves can appropriately increase the air humidity.

4. Treatment of leaf spot

Cause: Leaf spot is a relatively common disease that causes brown spots to appear on the leaves, which then turn black.

Solution: Cut off the diseased branches and leaves of the green radish, and spray maneb for prevention and control. In addition, it should be placed in a place with good air circulation, and you can also apply some compound fertilizer appropriately to avoid recurrence.
