Common Diseases and Their Treatments

• Black Tip Fungus: Causes blackening of the leaf tips. To prevent this, ensure good airflow around the plant and avoid getting water on the leaves. If the plant is affected, remove and dispose of the infected parts and apply a suitable fungicide.
• Rust Fungus: Causes orange pustules on the underside of leaves. To prevent, keep foliage dry and ensure good air circulation. If affected, remove infected leaves and apply a fungicide.
• Root Rot: Causes yellowing and wilting of leaves. It is often due to overwatering or poor drainage. Adjust watering schedule and improve soil drainage. If the plant is already infected, remove it from the pot, cut away the rotten roots and repot in fresh, well-draining soil.

Pest Issues and Control Methods

• Mealybugs: Small, white, cotton-like pests that suck the sap from the plant, causing yellowing and curling of leaves. Wipe off with a cotton swab dipped in alcohol or apply a suitable insecticide.
• Spider Mites: Small, spider-like pests that cause speckling or bronzing of leaves. They can be washed off with water or controlled with an appropriate miticide.
• Aphids: Small, green or black insects that suck the sap from the plant, causing distorted growth and sooty mold. They can be washed off with water or controlled with a suitable insecticide.
• Whiteflies: Small, white, winged insects that suck sap from the plant, causing yellowing and stunted growth. They can be controlled by introducing natural predators, using yellow sticky traps, or applying a suitable insecticide.

Nutrient Deficiencies and Solutions

• Nitrogen Deficiency: Causes yellowing of older leaves. Use a balanced fertilizer that includes nitrogen.
• Phosphorus Deficiency: Causes darkening or purpling of leaves. Use a balanced fertilizer that includes phosphorus.
• Potassium Deficiency: Causes yellowing or browning along leaf edges. Use a balanced fertilizer that includes potassium.

Environmental Stressors and Mitigation Tactics

• Overwatering and Underwatering: Overwatering causes yellowing of leaves and root rot. Underwatering causes wilting and browning of leaf tips. Adjust watering to the plant’s needs, which vary depending on the temperature, humidity, and the size of the plant and pot.
• Temperature Stress (Cold and Heat): Cold stress can cause leaf drop, while heat stress can cause sunburn (white or brown spots on leaves). Adjust the plant’s location or provide protection to mitigate temperature extremes.
• Light Stress (Too Much or Too Little Light): Too much light can cause leaf scorch (brown spots or edges), while too little light can cause weak, leggy growth. Adjust the plant’s location to provide the right amount of light.
• Sunburn: Causes white or brown spots or edges on leaves. Prevent by providing shade during the hottest parts of the day or gradually acclimating the plant to more intense light. If sunburn occurs, it can’t be reversed, but the plant can recover with proper care.
