Treatment of damage If no more frost is expected, prune out damaged growth, cutting to an undamaged sideshoot or bud. After pruning, apply a top dressing of a general-purpose fertiliser, such as Growmore at the manufacturer’s recommended rate, to encourage strong re-growth.
Can plants recover from frost damage?
In the event of a light freeze, a plant’s foliage may be damaged or discolored. While the plants may recover in time, there’s also a chance that they may not. However, you should still give them several months just to be sure. Over time, the impacted plants will recover, especially if they are native to your area.

Will cold weather hurt my tomato plants?
One fact is certain: tomatoes do NOT like to be cold. But tomato plants can survive a cold snap or even a series of cool nights.

What is freezing temp for plants?
