Overview
- Media and garden authorities are warning that imminent first‑night frosts mean owners should assess each container plant and take immediate action for the most vulnerable specimens.
- The Bayerische Landesanstalt für Weinbau und Gartenbau advises moving tropical species such as ornamental banana, papyrus, bougainvillea, angel’s trumpet and lipstick vine into winter quarters before light frosts occur.
- The Landwirtschaftskammer Nordrhein‑Westfalen cautions that some plants are better left outdoors as long as conditions permit because poor indoor wintering can weaken plants over the season.
- Merkur highlights five high‑risk plants—dipladenia (Mandevilla), citrus, angel’s trumpet, lipstick vine and oleander—and recommends specific winter‑quarter targets where many species do best at about 5–12 °C with brighter sites needing higher temperatures.
- Prepare plants by letting root balls dry slightly, removing saucers, pruning long growth, checking for pests, insulating pots with bubble wrap or matting and elevating containers to reduce ground frost risk.
