FROM CAMEL VALLEY VINEYARD APRIL
The cool dry spring has been surprisingly good for us this year.
Late frost is the greatest threat during spring for established
vines, and although we all enjoy those lovely warm spring days with
clear blue skies, this is exactly the sort of weather pattern where
frost arrives in the early hours and kills off emerging buds and
leaves. This April I can hardly remember a day with a cloudless sky
when it was even warm enough to go out without a coat, so little
chance of frost.br>
Just to be on the safe side we ordered a new oil-based spray, which
is supposed to protect buds and leaves from frost. The problem with
it is that it is only effective for two weeks and is prohibitively
expensive to spray more than once in a season. Therefore you have to
select the time you spray very carefully – if you spray too early in
the spring when there is no frost forecast for the foreseeable
future, you might end up with frost when the spray is no longer
effective. If however you hang on until frost is forecast you may
not have enough time to get the vines sprayed and protected before
it arrives. |
