Overview

• HNA consolidates expert advice urging relocation before the first frost, with November flagged as the decisive window once nights approach 8°C.
• Recommended winter quarters include winter gardens, heated greenhouses or bright stairwells, whereas living rooms are too warm and basements or garages too dark.
• During dormancy water only every two to three weeks and stop fertilizing to avoid root rot and pest problems.
• Maintain higher humidity, with occasional misting using low‑calcium water to prevent leaf rolling and keep foliage healthy.
• Skip an autumn cut on small plants, prune larger specimens before moving indoors, and remove fallen leaves and flowers; return outside only after late cold snaps in spring.
