🌱 How to Care for Licorice Plant to Prevent Aphids?

💧 How to Water

Water deeply but infrequently, only once the top 2-5 cm (1-2 in) of soil has dried out. In containers this is usually every 7-12 days; in the ground, established plants may need water only during prolonged dry spells. Always let excess water drain away and never let the pot sit in a saucer of water.

☀️ Lighting

Position in full sun to light shade. The silvery foliage color is most intense with at least 5-6 hours of bright, direct sun a day; in deep shade growth becomes sparse and less colorful.

🪴 Ideal Soil

Plant in loose, well-draining soil such as a standard potting mix amended with perlite or coarse sand. Heavy, waterlogged or clay-rich soils quickly lead to root rot, so drainage matters more than fertility.
