Questions people ask

- If you catch it early, yes. Trim the bad roots, change the soil, and be very careful not to overwater while it recovers.
- How often should I water to prevent rot?
- Water every 5 to 10 days, but only when the top inch of soil feels slightly dry. Never water on a strict calendar if the soil is still damp.
