🌱 How to Care for Kris Plant to Prevent Leafminers?

💧 How to Water

Water deeply once a week during spring and summer when the top 1 inch of soil feels dry. In autumn and winter, reduce frequency to every 10–14 days. Never let the plant sit in standing water — always use a pot with drainage holes to prevent root rot.

☀️ Lighting

Place in bright indirect light, ideally within 1–2 metres of an east- or west-facing window. Avoid direct afternoon sun which scorches the leaves. At least 6 hours of bright filtered light per day is essential for healthy growth.

🪴 Ideal Soil

Use a well-draining tropical mix: combine peat moss or coco coir with perlite and a small amount of orchid bark. Aim for a pH of 5.5–7.0. Never use heavy garden soil — it retains too much moisture and risks root rot.
