The proper time to remove straw from matted row strawberries is when the bare-soil temperature at 4 inches averages about 40-43˚F. This usually coincides with mid to late March in central Indiana. This year is earlier than average with soil temperatures well into the 50s in early March, but they dropped back below 40 during[Read More…]

We have just finished harvesting Pixie crunch from our plantings at the Purdue Meigs farm and the more I see this apple, the more I like it. Although we think of this as a relatively new apple, the original cross was made 45 years ago at Rutgers University and it was selected from a planting[Read More…]
Grape harvest continues across the state. Overall fruit quality has been excellent, but maintaining that quality with all the rain recently is challenging. Thin skinned varieties have fruit cracking and rot problems. Primocane fruiting blackberry harvest continues into its fourth week on Black magic, with APF-45 just getting started. Heritage and Caroline primocane fruiting raspberries[Read More…]
Hopefully, everyone somehow managed to obtain effective fungicide coverage during the wet summer of 2016, and the torrential rains of the last few days.

June bearing strawberries are “short day” plants that set flower buds in response to short days. As we get into late summer, days shorten and strawberry plants respond by setting the flower buds that will result in the crop next spring.

Fruit quality overall is very good. Many vineyards are still recovering from the winter of 2014 so yields will still be below normal. With[Read More…]
Plant nutritional status is important for all phases of plant growth and has a direct effect on vigor, fruitfulness, cold hardiness, and other factors. Tissue analysis is the most reliable means of determining plant nutritional status. Combined with soil testing, tissue analysis can help pinpoint the source of problems and determine what measures may be[Read More…]
