You should ideally have already trimmed back plants susceptible to wind rock and cold, such as shrub roses, Lavatera and Buddleia, by between a third and half of their height in the autumn - and moved vulnerable plants like Olea europaea (olive) indoors.
BBC Gardeners' World expert names top plant that will survive a cold snap The chilly weather is causing chaos in our gardens, and it can be tricky to know how best to protect your beloved plants when temperatures drop so drastically.
Luckily, BBC Gardeners' World host Mark Lane has offered some handy tips, as well as suggesting which plants are likely to survive a cold snap - and those that aren't.
Wind greatly contributes to transpiration, as does a cold snap, which is why Mark suggests it's wise to prune back certain plants, like herbaceous perennials.
Transpiration involves moisture being transported through plants from roots to small pores on the underside of leaves, where it turns into vapour and is released into the atmosphere.
