Nova Scotia Wild Blueberry Best Management Practices | ||||||||||||
The Nova Scotia Wild Blueberry Best Management Practices web directory was developed and designed through the Sustainability Committee of the Wild Blueberry Producers Association of Nova Scotia with help from Perennia. The purpose of this webpage is to highlight the BMPS from all aspects of wild blueberry production in Nova Scotia. It will help growers and other interested parties easily access resources on how to produce wild blueberries sustainably and in an economically viable manner. The intent of this page is to keep practices updated and relevant to modern wild blueberry production. |

4.0 Field Management | ||||||||||||
4.1 Crop Monitoring |
||||||||||||
Growers regularly visit fields to observe crop development, pest levels and general plant vigour. |
||||||||||||
back to top | ||||||||||||
4.2 Pruning |
||||||||||||
Pruning is a critical process, typically done in the mid to late fall after the harvest, or early spring the following year. Pruning can be delayed by one year in fields that have good second crop potential. The New Brunswick Department of Agriculture, Aquaculture and Fisheries has a useful factsheet on burning. |
||||||||||||
back to top | ||||||||||||
4.2.1 Mowing |
||||||||||||
Mowing is the least expensive way to prune a blueberry field. Growers must maintain the mowers so that they operate optimally. Flail mowers are the preferred mowing device. |
||||||||||||
back to top | ||||||||||||
4.2.2. Burning |
||||||||||||
Pruning by burning is an expensive yet valuable process that is done selectively by the grower. Burn pruning will prune stems to the ground encouraging new shoots from the rhizome, release nutrients for the plant, and reduce certain pest pressures. Excessive burning will result in the reduction of soil organic matter and the decrease of plant health in certain soils. Burning also has liability concerns that must be realized by the grower. Burning permits are obtained from Nova Scotia Department of Natural Resources when required. |

4.3 Soil Management |
||||||||||||
The soil is the medium in which the blueberry plants are grown. Maintaining soil stability and soil structure is critical for long-term viability. Since wild blueberries are a long-term perennial crop, there are few options to repair soil damage once it has occurred, therefore conservation is critical. |
||||||||||||

4.3.1 Erosion Prevention |
||||||||||||
Soil conservation is a high priority in wild blueberry production The New Brunswick Department of Agriculture, Aquaculture and Fisheries has a useful factsheet on the use of mulches |
