More Resources on Blueberries
Since my post on Fruit for the Month of February, I have found some more really good resources on blueberries
Blueberries are easy to grow if conditions are right. They are a popular choice with organic growers, because they don’t need any pesticides to produce a good crop. They do, however, need annual pruning to be sure of a high quality crop. Pruning also keeps the bushes at a height easy to harvest from. Pruning is done during the dormant season, usually between December-early March in the Piedmont.
Some people are reluctant to prune because it does remove some of the flower buds and reduces berry production for that year, but if pruning is not carried out, berries become smaller each year and the health of the bushes declines. Pruning is an investment in the long-term success of your plants!
The Growing Small Farms website links to many how-to videos and fact sheets, with diagrams and photos. There are excellent resources on pruning and blueberry production in general. Everything you need to know about pruning blueberry bushes!
Another good resource is this article in the Agricultural Research Service newsletter
More People are Getting the ‘Blues’
By Scott Elliott, ARS Office of Communications.
Here is some recent information on blueberry research. New varieties, and a disease to watch out for.
Researchers at the Horticultural Crops Production and Genetic Improvement Research (HPCGIR) Unit in Corvallis, Oregon, are developing new cultivars of not just blueberries, but also blackberries, red raspberries, black raspberries, and strawberries to meet the particular needs of growers in the Pacific Northwest. Also useful to those in other areas.
“We focus on improving the shelf life of fruit so that it reaches consumers with consistently better texture and flavor,” said Claire Luby, plant geneticist with HCPGIR. Perhaps a large challenge for Luby and her colleagues is developing a cultivar that is resistant to a disease known to be a scourge of the berry: blueberry shock virus.
“We’re studying diverse blueberry plants to understand the genetic basis for blueberry shock virus, which can significantly impact yields for farmers,” she said. “Our hope is to use the insights from this project to develop new cultivars that are resistant, or at least more tolerant to, the disease.” Blueberry shock virus has caused annual crop losses of 34-90% in the Pacific Northwest.
Researchers combine traditional plant breeding with genomics to create their disease-resistant cultivars. The traditional technique (used in one form or another by people trying to improve agricultural crops for millennia) is to take pollen from one plant and use it to pollinate a different plant with complementary characteristics. They study the progeny of these crosses, looking for new characteristics that meet the goals of the breeding programs. Traditional blueberry breeding can take more than 20 years from the time an initial cross is made to when a consumer might eat from a resulting cultivar.
“We try to improve the accuracy and speed of the plant breeding process,” Luby explained. “We are now able to obtain a lot more genetic information about the plants and we can use that information to potentially predict whether an offspring of a given cross might have the characteristics we are looking for before we plant it out in the field. This is important because it can increase the speed of the plant breeding process.”
“Our goals are to develop blueberries that require fewer chemical inputs to fight disease, which can be better for both the environment and for growers’ bottom lines,” Luby said.

Crop Planning for Sustainable Vegetable Production
At the in-person Pasa Sustainable Agriculture Conference, I gave two presentations. I also sent a recorded workshop for their virtual conference in January. That one was Feeding the Soil. I’ve just scoured through all 8 pages on my website that check the category “Slideshows”. I found Feeding the Soil twice.
My Alliums Year Round presentation is new this year and I posted the handout after my presentation at VABF. Pasa had shorter workshops, so I pruned the slideshow, but left the handout with the “bonus material”.
My other presentation at Pasa was Crop Planning for Sustainable Vegetable Production. That is one of the very first topics I tackled when I started out as a speaker, so the three versions on this website span the past ten years. 2014, 2016, 2019.
