Care Tip: Pinch growing tips and deadhead spent flowers to promote continuous blooming; thin seedlings to 30β40 cm apart for good air circulation.
Common Pests
Aphids
Symptoms: Clusters of small green or black insects on stems and new growth; sticky honeydew residue and curled or yellowing leaves.
Treatment: Spray with a strong jet of water or apply insecticidal soap or neem oil.
Prevention: Encourage beneficial insects such as ladybugs and lacewings; avoid excessive nitrogen fertilization.
Thrips
Symptoms: Silver-white streaks or stippling on leaves and petals; distorted or discolored flower heads.
Treatment: Apply neem oil or insecticidal soap; remove and destroy heavily infested plant parts.
Prevention: Keep the area free of plant debris and weeds; use reflective mulch to deter thrips.
Mealybugs
Symptoms: White cottony masses on stems and leaf axils; stunted growth and leaf yellowing from sap-feeding.
Treatment: Wipe off with rubbing alcohol on a cotton swab or spray with insecticidal soap.
Prevention: Inspect new plants before adding them to the garden; avoid overwatering and over-fertilizing.
Common Diseases
Powdery Mildew
Symptoms: White powdery coating on leaves and stems, often leading to leaf yellowing and drop.
Treatment: Remove affected foliage; apply a sulfur-based or potassium bicarbonate fungicide.
Prevention: Ensure good air circulation by spacing plants properly; avoid overhead watering.
Botrytis Blight (Gray Mold)
Symptoms: Gray fuzzy mold on older leaves and the center of the plant; tissue becomes soft and rots.
Treatment: Remove and destroy infected plant material immediately; apply a copper-based fungicide if severe.
Prevention: Plant in well-drained soil, avoid crowding, and water at the base to keep foliage dry.
Damping Off
Symptoms: Seedlings emerge healthy then suddenly wilt, collapse at the soil line, and die.
Treatment: No cure once symptoms appear; remove affected seedlings to prevent spread.
Prevention: Use sterile seed-starting mix, avoid overwatering, and provide good ventilation around seedlings.
