now find ourselves, and plot a safe route forward.
In answer to Philip's question: Are you suggesting the possibility of

Hello apple people,
The apple harvest here in Ireland is about two weeks ahead of schedule,
or perhaps I should say that apple maturity is two weeks ahead of
normal, because not everyone is picking as soon as perhaps they should.
The spring was early and warm here this year, which got the fruit
coming from the Lituania Prognosfruit

I have no problem with the lifestyle here. However, I get the impression
that one dollar will buy more in the US than one euro will here. Ireland
is an expensive country to live in.
There are also reports of some freezing temperatures in continental
Europe, down to 19.5F in parts of Holland. No news on damage as of yet,
but frost protection was in full swing with those who have it.
That is a nice piece of work. It is important to be consumer (rather

Hello Dr. Parmar,
Just a suggestion, but production of ABA, which regulates dormancy, is
encouraged by shortening days and lengthening nights. At 6 degrees
south, daylength will not change, so I suspect that there might not be

In Ireland we have used it in winter also, but it is hard work (rough on
