Michigan State University Extension has released its fruit update.
"Tart cherries are in full bloom and sweets are starting to drop their petals. Gala are at 15% bloom and Honeycrisp are at king bloom. We have had excellent pollination weather for the last three days and black stem borer is in peak flight.
Weather report
The weather has been beautiful across the region. With sweet and tart cherries in bloom, this sunshine and warm weather is perfect for pollination. Over the weekend, we had daytime temperatures top out at 72 degrees Fahrenheit on Saturday, May 4. Today, May 7, is predicted to be the warmest day of the week with daytime highs near 70 F. After today, a cold front moves in, and the highs for the remainder of the week are only in the mid-50s to 60 F.
Pollination weather has been excellent for the past few days, and cherries should have had adequate time for bees to work their magic. Bee activity has been strong in the hives at the Northwest Michigan Horticulture Research Center. There are ample bees in the blooming canopies during the warmer hours of the day.
We are starting to see bloom in apples as well. Gala are ahead of Honeycrisp, and we are seeing a good number of flowers on trees at the research center. We have also heard of good bloom in apples across the region, which is notable as we have had back-to-back big apple crops in the state for the last two years. Pears are also blooming at the Northwest Michigan Horticulture Research Center."
