why shouldn't you prune if frost forecast?
just mulling over the scientific reasons why you shouldn't prune hardy shrubs when frost is forecast...
have been 'brought up' to avoid pruning in very cold weather and this does instinctively feel right, but anyone have any clues as to why? I would guess that the cells on the exposed cuts could be damaged by low temperatures, therefore encouraging nasty wounds etc etc - but been a while since I did all that at college, anyone remember the reasons?

Instinctively I would have thought that pruning in very cold weather would be a good idea as the plant would be dormant, but that pruning in frost would be a bad idea as the cut area could be damaged by frost and the plant would not have an opportunity to heal the wound. So which is right? |

I do all my pruning while the plant's dormant, fruit trees, roses, grapes,
etc. That is the way I was taught and I continue to do it as close as I can to the first of February, weather permitting.

So which is right? I wonder if it's to do with the moisture, expansion then contraction tearing the cells apart. It's not good for human parts either! Richard. |

The message
from "Dwayne" contains these words: I do all my pruning while the plant's dormant, fruit trees, roses, grapes, etc. That is the way I was taught and I continue to do it as close as I can to the first of February, weather permitting. what is your lowest winter temperature, Dwayne? Janet |

The lowest winter temp I have seen here has been around -29 C, but it has
been a long time since it was that cold. Normally it only gets down to about -25 C. Dwayne "Janet Baraclough" wrote in message ...
