I noticed today that the hazelnuts have flowered out. At least the Northern and Het hazels have flowers and catkins, the other varieties don’t have flowers yet. We have had some warm weather, so that must have activated the flowering process. It is much earlier than normal, so my theory of day length seems to be in question. It seems that flowering is a matter of warmth of day.
Now comes the difficult part, watching the weather and hoping it stays warm enough for the hazelnut fertilization to survive.
Here is a summary of the temperature for the last couple of weeks Mar 20 - April 3:
Max Temp: 16.8 °C
Max Temp.Date: Mar.28 2010
Min temp: -6.1 °C
Min Temp. Date: Mar.25 2010
Precip Accumulation: 0 mm
Update
We did have a snow storm for a week but the temperatures were relatively mild. Below is a summary of the recent weather (April 4-22):
Max Temp: 23.2 °C
Max Temp.Date: Apr.20 2010
Min temp: -8.5 °C
Min Temp. Date: Apr.5 2010
Precip Accumulation: 7.6 mm
The key piece of data is the -8.5 °C. It will be interesting to see if that impacts nut production.
It is now April 22 and the hazelnut leaves are just starting to come out. We have had warm summer like conditions for the last few days.
May was cold as well - had several snow storms but I think -8.5 °C was as cold as it got.
