In north Dublin last week I recorded temperatures just over -8 celcius and although the wind chill factor was something a lot greater than that, with the recent weather and the subsequent thaw….what one can see now is [maybe] mildly uncertain regarding what plants have survived the minus temperatures due to the fact that a lot are at present leafless and dormant.
A plants cells are made up essentially of water and in extreme conditions that water in the plant cells expands resulting in the cells bursting. The bit that’s important to you, the plant owner, is that once the plant cell has burst it is dead – and – put very simply beyond resurrection.
The question is how far or how much of the plant is actually dead, if it has just burnt some of the leaves or it has actually made it’s way into the ‘heart’ of the plant. For this there’s really no one definitive answer, but [for example] for my own bay laurel hedge [above] I’ll simply cut out the brown and work my way down the stems until I can only see green. It may well look a bit sparse and patchy after, but it’ll come back for next season. Smaller and younger plants may not have been so fortunate.
My advice is to get out into the garden and have a good rustle through the aftermath and give each plant a good close up inspection. In fear of a frost return you may consider mulching around the base of your plants which will aid them that little bit better – and – they will thank you for it come the new year.
Unsure if one of your plants has survived [?] you can contact me in the following ways…
