🌱 How to Care for Lantana to Prevent Leafminers?

💧 How to Water

Water every 7–10 days once established, allowing the soil to dry between waterings. During the first growing season, water more regularly to support root establishment. Never let water pool around the base — Lantana is highly susceptible to root rot in waterlogged conditions.

☀️ Lighting

Lantana requires full sun — at least 6 hours of direct sunlight daily. In partial shade, the plant becomes leggy and produces significantly fewer flowers. Place in the sunniest spot in your garden or on a south-facing patio.

🪴 Ideal Soil

Use well-draining soil, such as sandy loam or a general-purpose mix amended with perlite. Lantana tolerates poor soils and does not need rich substrate. Avoid heavy clay soils that retain moisture. Ideal pH is 6.0–8.0.
