Dracaenas need a consistent watering regime. They don’t fare well if they’re either overwatered or underwatered. Only water your plant once the soil’s dry to touch at the top of the soil.
When watering, water your plant thoroughly and ensure water flows all the way through the pot, tipping away any excess in the ceramic or basket. This will prevent root rot.
During winter months, they require less water just be careful not to leave it to fully dry out for long periods of time. This can also be the cause of browning leaves.
