Grape: Full veraison on most varieties

Apple harvest has begun with early varieties still being harvested. A lack of cool nights has delayed red color development but many varieties are still developing acceptable red color. Quality generally looks good.

With weird weather often comes weird physiological disorders (on top of our summer fruit rots). Often confused with hail injury, disease or insect damage, these physiological disorders are marring the appearance of many apples. Symptoms of bitter pit include circular or even irregular sunken spots on the fruit surface, beneath brownish or streaked dead regions (Fig. 1). Note that the damage can be separated from the skin surface. Symptoms may be mistaken for hail damage, or any of the below problems. A key diagnostic feature is that hail usually affects only one side of the fruit, whereas bitter pit is more severe on blossom end of the fruit. Some varieties, like Honeycrisp, are more prone to this disorder, whereas hail will impact (literally) all varieties of fruit. Bitter pit can show up throughout the orchard, not just the edges. Cork spot is another physiological disorder affecting outer portion of the[Read More…]


With harvest around the corner for many fruit crops, I thought this would be a good time to remind readers about our email lists. Various forms of social media is used by just about everyone in today’s society.  While Facebook and Twitter are much more commonly used than email, there is still a place for email lists. Mail lists continue to be a successful communication tool for groups of people. The way a mail list works is that people subscribe and then have the authority to post messages to the list. All other subscribers on the list receive the messages. One message can be sent to hundreds of readers at once. Replies to messages on a mail list can either go only to the sender of the message or to the entire list. Purdue HLA Extension maintains two mail lists for users. The “Fruitveg” list is for all fruit and vegetable growers, farm[Read More…]


Grape harvest is just about to get started in the southern part of the state. Growers will start harvesting early varieties next week. Most varieties are slightly ahead of normal this year. In Lafayette, early varieties are at full veraison and should be ready to harvest in the next couple of weeks. We generally harvest early varieties such as Brianna, Edelweiss and Prairie Star about the third week of August and many other early varieties starting the first week of September. Depending the weather for the next couple of weeks, we might be a bit early this year. Fruit quality overall is very good. The cooler conditions lately have favored fruit quality. With wine grapes, all fruit of a given cultivar is typically harvested from the vineyard or block at a single time to coordinate winery activity and to reduce costs. It is important to plan carefully so that the[Read More…]


June bearing strawberries are “short day” plants that initiate flower buds in response to short days (less than 14 hours day length). Day length for Indianapolis drops below 14 hours about August 10.  As we get into late summer, strawberry plants respond to shorter days by setting the flower buds that will result in the crop next spring. It is important to maintain appropriate nutrition and soil water status during this time. General recommendations are to fertilize strawberry fields with 20 to 50 pounds of actual nitrogen per acre per during late summer.  Nitrogen rates depend upon amount supplied at renovation and plant vigor. New fields with high vigor may not need additional nitrogen now, but older fields should benefit. Irrigation during this time is also extremely important if rainfall has not been sufficient in your area. We suggest about 1 inch per week. Continue to irrigate strawberries through fall[Read More…]


Strawberries are primarily grown in the matted row system in Indiana, in which bare-root strawberry plants are set in the spring, fruit is first harvested in the second year and plantings are renovated each year for a few seasons. Growers in Southern Indiana have expressed interest in growing strawberries in the annual plasticultural system. With this annual system, plants are set in the fall and harvested in the spring of the following year. Plantings are not normally carried over a second year. Although the annual plasticultural system is very popular in the southern states, its usage is limited in Indiana mainly because our short fall weather conditions pose a challenge for strawberry plants to develop enough branch crowns, which allows them to achieve the optimal yield in the following spring. In the past two years, we have been testing the annual strawberry production system with additional protection from high tunnels[Read More…]
