This winter was significantly colder than normal in the northern half of Indiana. Many areas north of “I-70” experienced temperatures between -15 and -20˚F in early January. That is cold enough to cause considerable cold injury to grapes, peaches, and blackberries. Ten below zero is a commonly accepted threshold for seeing damage to cold sensitive…Read more about Cold Injury to Fruit Crops[Read More]

Apple harvest is winding down with late varieties such as GoldRush and Pink Lady being harvested. Quality has continued to be good, although some stem-end cracking has shown up on some cultivars. We have continued to run about a week early throughout the season.
Fruit rots continue to pose a problem for those of us in the wetter parts of the state.

Any rain event that produced more than 2” of rain would remove the majority of fungicide, meaning…Read more about Fruit Rots[Read More]
