2017 ASHS Annual Conference

Containers for blueberries were then top-dressed with four different treatments of Topdress Special 17-3-6, a slow-release macronutrient. The treatments were 47 (g), 94 (g), 141 (g) and 188 (g). Containers for raspberries were top-dressed with four different treatments of Osmocote 15-9-12, a 6-month slow-release macronutrient. The treatments were 47 (g), 94 (g), 141 (g) and 188 (g). 144 (g) of Dolomitic Lime per container was also amended into the media to raise the pH up to around 6.8, the desirable level for this crop. Containers for Blackberries were top-dressed with 126 (g) of Osmocote 15-9-12, a 6-month slow-release macronutrient. These were also amended with 144 (g) of Dolomitic Lime per container to raise the pH up to around 6.8. There are four different winter protection treatments for these; they are: moving containers into a protected structure like a barn, moving containers into a four-season high tunnel, covering containers with two layers of 0.9 ounce row cover and covering containers with four layers of 0.9 ounce row cover. During the growing season, all containers were on landscape fabric in a nursery style setting. All containers were irrigated using 6.6 Gph spray stakes. Fruit yield and quality data from the 2017 season will be summarized and presented.
