🌱 How to Care for Common Chickweed to Prevent Tomato Spotted Wilt Virus (TSWV)?

💧 How to Water

Water enough to keep the soil consistently moist but not waterlogged - roughly every 2-3 days in dry weather. Chickweed struggles and dies back quickly in drought, so do not let the soil dry out completely.

☀️ Lighting

Grows best in full sun to partial shade. In hot climates, a bit of afternoon shade helps prevent the foliage from wilting during summer heat.

🪴 Ideal Soil

Prefers rich, organic, moisture-retentive soil with good drainage, from clay to sandy loam, at a mildly acidic to neutral pH (around 5.5-7.5). Tolerates occasional wet or flooded conditions.
