Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.

Buds stall or the pot feels light.

Seasonal and environmental adjusters
