FAQ

Should I water my plant strictly on the calculated D-Day?
No. The D-Day is a guideline to check the soil. Always test the soil dryness physically (e.g., using a wooden chopstick) before adding water to prevent root rot.
Should I follow the same schedule for a pot with no drainage hole or poor drainage?
No. The suggested interval assumes a typical pot with good drainage. In a pot without a drainage hole, or with dense, slow-draining soil, the soil actually stays wet much longer, so it's safer to wait a few extra days beyond the suggested date and check the soil directly before watering, to avoid root rot.
