The reason why the leaves of the fire festival have black spotsHumid environmentRegardless of the change of seasons, your succulents are always at home. You can take them outside for a walk in all seasons, so why can you only stay at home during the Fire Festival? Poor ventilation, frequent watering and a stuffy environment can easily induce pathogens, causing black spots to appear on the leaves. Improper wateringThe wrong watering method will also affect the growth of the fire festival. Every time you water it, do you water it directly from top to bottom, wetting both the leaves and the soil? However, the water has already entered the center and surface of the leaves, which can easily attract pathogens and cause black spots to appear on the leaf surfaces. Improper fertilizationPlants grow weak and are easily attacked by diseases and pests, which is a sign of fertilizer deficiency. The fact that the leaves of the Fire Festival plant are not red is generally believed to be due to lack of sunlight, but it is also a sign of lack of nutrients. If fertilizer is not applied regularly, the plants will lack nutrients, have poor resistance, and the leaves will not turn red, but will also show adverse reactions such as yellowing and black spots. What to do if black spots appear on the leaves of Fire FestivalSupplement nutrientsAppropriate fertilization: Apply thin liquid fertilizer to the soil once a month or two months during the growth period, mainly phosphorus and potassium fertilizers, to enhance the resistance of the plant. Reduce water sprayingEspecially when the environment is hot and humid, do not spray water on the leaves frequently. Just water the plant normally when the soil in the pot becomes dry. Do not flood the plant with too much water. During maintenance, try not to damage the leaves to prevent wound infection and fungal diseases. Apply powderWhen black spots appear on the leaves of the fire festival plant, apply fungicide in time, and combine leaf spraying and root irrigation, once every 7 days. Alternatively, apply carbendazim powder directly on the leaves, once every 5 to 10 days, until improvement is seen. |
