Make a priority list
Write down the plants most vulnerable to cold, including tender species, newly emerging growth and plants already in flower. Check their requirements individually. A local forecast describes a wider area, while a low, exposed or sheltered corner can behave differently. Place a simple minimum thermometer near the plants if you want to understand your own space better. Record the position with the reading; a measurement beside a warm wall does not represent an open balcony edge.
Pack practical protection
Keep suitable horticultural fleece, clips, labels and a few supporting canes together in a dry container. Test the arrangement before it is urgently needed. Covers should be secure enough to resist movement without crushing soft stems. Different materials and setups provide limited, variable protection; none should be treated as a guarantee against severe cold. A plant that genuinely requires frost-free conditions may need to move to an appropriate protected space rather than remain outside under another layer.
Plan the morning as well
Protection is a routine, not just an evening action. Decide who will check the plants and adjust or remove covers when conditions improve. A cover that stays in place through a warm sunny day can create a different problem. Keep access to the pot so that moisture can still be assessed. If several plants share a cover, leave enough space to prevent foliage being pressed together. Label any plants hidden by wrapping so their care remains individual.
Respond calmly after a cold night
Photograph suspected damage and allow time to see its extent. Avoid cutting away everything immediately or adding fertiliser in the hope of reversing injury. Some plants reveal recovery or further dieback only later. Check plant-specific guidance before pruning. Note which locations experienced damage and which remained protected. This becomes a practical map for the next warning: the useful result is a more accurate protection plan, not a belief that one temperature describes every plant's tolerance.
