🌱 How to Care for Lady Valentine Chinese Evergreen to Prevent Leaf Spot?

💧 How to Water

Water thoroughly, until it drains from the pot, once the top 3 to 5 cm of soil are dry. In warm months that is usually about once a week; in winter, every 10 to 14 days. Do not let the soil stay soggy or water sit in the saucer, or the roots will rot.

☀️ Lighting

Medium to bright indirect light, near a bright window but out of direct sun, which scorches the leaves. The more light it gets, the deeper the pink. In low light it loses colour, grows less and makes smaller leaves.

🪴 Ideal Soil

A well-draining indoor potting mix with perlite or pumice added (for example 3 parts potting soil to 1 part pumice). A little coco coir and compost help hold moisture without waterlogging.
