Gerbera daisies are sensitive to both overwatering and underwatering. Overwatering can lead to root rot, as their roots are prone to fungal infections in soggy soil. Conversely, underwatering causes wilting and stunted growth. The key is to keep the soil consistently moist but not waterlogged. Water deeply when the top inch of soil feels dry, and ensure proper drainage to prevent standing water.
Gerbera daisies thrive in bright, indirect sunlight. A common mistake is placing them in low-light conditions, which results in leggy stems and fewer blooms. However, direct afternoon sun can scorch their leaves. Ideally, provide 6-8 hours of filtered sunlight daily, such as near an east- or west-facing window or under partial shade outdoors.
These plants require well-draining, nutrient-rich soil with a slightly acidic to neutral pH (6.0–7.0). Heavy clay or compacted soil restricts root growth and retains excess moisture, while sandy soil drains too quickly. Amend the soil with organic matter like compost or peat moss to improve texture and fertility. Avoid using garden soil alone in containers, as it may lack proper aeration.
Gerbera daisies are heavy feeders, especially during their blooming season. A common mistake is skipping fertilization or using the wrong type of fertilizer. Use a balanced, water-soluble fertilizer (e.g., 10-10-10) every 2-4 weeks during active growth. Over-fertilizing with high-nitrogen formulas can promote leafy growth at the expense of flowers, so opt for a bloom-boosting fertilizer (higher in phosphorus) as buds form.
Common pests like aphids, spider mites, and whiteflies can weaken Gerbera daisies, while fungal diseases like powdery mildew or crown rot may arise from poor air circulation or excess humidity. Inspect leaves regularly for pests and treat them with insecticidal soap or neem oil. Prevent fungal issues by spacing plants adequately, avoiding overhead watering, and removing dead foliage promptly.
Gerbera daisies prefer daytime temperatures of 65–75°F (18–24°C) and cooler nights. Extreme heat or cold stresses the plant, causing leaf yellowing or drooping. Indoors, avoid placing them near drafts or heating vents. Outdoors, protect them from frost. Moderate humidity (40–60%) is ideal; too much humidity encourages disease, while dry air may cause leaf edges to brown.
Deadheading—removing faded flowers—is crucial to encourage continuous blooming. Neglecting this task diverts energy to seed production instead of new flowers. Use clean scissors to cut spent blooms at the base of the stem. Regularly check for and remove wilted or diseased leaves to maintain plant health.
Gerbera daisies dislike root disturbance, so repotting too often or at the wrong time can shock the plant. Repot only when roots outgrow the container, preferably in spring. Choose a pot 1-2 inches larger in diameter with drainage holes. When transplanting outdoors, acclimate the plant gradually to outdoor conditions to avoid transplant shock.
