Mulch prized plants
Protect precious tender plants in the ground with dry mulches (e.g. bracken under pegged-down fleece) rather than bubble wrap or polythene.
Chives potted up and put in the greenhouse may give you some late extra leaves, and will sprout earlier next spring.
Ornamental vines and climbing roses that have dropped their leaves can be pruned back to within two buds of the main framework of branches.
Lollipop potted bay trees are vulnerable to frost. Drag them under the eaves if possible. Bubble-wrapping their trunks cuts down the death rate.
