How's your chilling and bloom going?
We just past the end of chilling season in many areas that might be short on chilling. And things have been blooming in CA and similar areas for many weeks.
In west TX at 4500ft elevation we were caught between the very cold East and very warm West. So we'd have a couple days too cold for good chilling and then several too warm and repeat at least once a week all winter. This is normal only this winter was extreme in that regard.
Results were outside:
1050 hrs below 45
580 hrs 32-45
470 hrs below 32
360 hrs Utah
This gave zero bloom on Robada and Orangered apricots. There were flower buds but they aborted and never opened.
1270 hrs Utah
This was achieved by holding the greenhouse 69 straight days where it never fell below 39F or rose above 57F. This gave 90% bloom on Robada and 60% bloom on Orangered both enough to require thinning. But as of right now my sweet cherries, which are just starting to bloom, still don't appear normal. The stigma looks normal but anthers don't appear to have much pollen. Maybe I'm warming them up too fast??
