Solutions to common problems in the daily cultivation of Epipremnum aureum
This introduction covers the solutions to common problems encountered during the daily cultivation of Epipremnum aureum. Let's follow the editor to take a look!
Symptom One
Internodes become weak and thin, leaves become thinner and paler, losing their luster.
Reason: Long-term placement in a dark environment.
Solution: Choose a new location with scattered light to place the plant, and spray potassium sulfate 3000 times solution to increase leaf thickness, and spray magnesium sulfate 3000 times solution to restore leaf color.
Symptom Two
In winter, the plant exhibits yellowing leaves followed by leaf drop.
Reason: Temperature is too low, should not be below 10°C.
Solution: Increase indoor temperature, add heating facilities such as electric heaters or electric fans. Stop fertilizing and control the substrate moisture to make it slightly dry to help the plant survive the winter.
Symptom Three
Initially, necrotic spots appear on the leaves like water soaking, and then quickly turn dark brown. Lesions have concentric rings of light and dark colors, surrounded by a yellow halo.
Reason: Caused by bacterial leaf spot disease.
Solution: Cut off all infected leaves and destroy them, stop spraying water, and when watering, make sure water droplets do not splash. Spray agricultural streptomycin 3000 times solution and 14% copper络ammonium solution 350 times, alternating sprays every 7 days, after 2-3 times, switch to once a month. The most important measure to prevent this disease is to maintain good hygiene in the environment around the plant (inside the potting soil).
Symptom Four
Stems turn black and rot, and in severe cases, the plant wilts and dies.
Reason: Accumulation of water in the infected area, and excessive moisture in the substrate.
Solution: Immediately clear the infected plant to prevent transmission to other plants in the same pot. Regularly spray benomyl 800 times solution at least once a month for prevention, and pay attention to controlling the moisture of the substrate.
Symptom Five
Above-ground leaves turn yellow and weak, and below-ground roots rot.
Reason: Accumulation of water in the potting soil.
Solution: Control moisture, do not fertilize before the plant recovers. Remove the plant from the pot, trim the rotting roots, and spray once with a mixture of potassium sulfate 3000 times solution and metalaxyl 1500 times solution. When the substrate is dry, apply a 3000 times solution of metalaxyl, then alternate with metalaxyl every month.
Symptom Six
New leaves become smaller, leaf color is dull, and there are burn marks on the leaf edges.
Reason: Excessive sunlight exposure.
Solution: Change the placement location.
Symptom Seven
The tip of the leaf turns yellow and dry, gradually extending inward, and the tip curves slightly upwards.
Reason: Leaf blight disease.
Solution: Trim the infected leaves and regularly spray thiophanate-methyl 1000 times solution for prevention.
Symptom Eight
Small brown spots appear on the leaf edges at first, then gradually expand, with visible circular halos on the leaf spots.
Reason: Caused by (T-J) disease.
Solution: Use carbendazim 500 times solution for spray control, trim infected leaves, and stop spraying water.
