Plant growth and development
- Primocanes continue to grow but growth rate is slower
- Flower buds start to form in leaf axils on summer-fruiting types
- Carbohydrates and nutrients in canes begin to move into the roots
- Primocane fruiting types begin to flower in late summer/early fall and fruit matures until frost in fall
- Primocane leaves senesce late fall
- Primocane-fruiting raspberry harvest
- Primocane-fruiting blackberry harvest
Pruning, trellising and tunnels
- Spent floricanes should be removed as soon as possible
- Optimal time to prune is after the coldest part of the season is over. However pruning can start in late fall if plantings are large (late winter for smaller plantings).
- Start trellis repairs after plants have defoliated
- Remove covers on three-season tunnels
- Many summer weed problems can be best managed in the fall and winter using preemergent herbicides. Determine what weeds have been or could be a problem in your area. Check with your states agricultural chemical manual and local extension agent for the best-labeled chemicals to control these weeds
Insect and disease scouting
- Continue scouting for insects and diseases
- Remove damaged canes as soon as possible to lessen the impact of the pest
- Check the Southern Regional Bramble Integrated Management Guide for recommendations
- Growers in warmer areas (e.g. extreme southeastern NC) can plant into early December. Preparations for winter planting should have already been made. If you have questions about winter planting please contact your local county extension agent
- In cooler areas, prepare list of cultivars for next spring’s new plantings. Find a commercial small fruit nursery list at https://blogs.cornell.edu/berrynurseries/
- Take soil tests to determine fertility needs for spring plantings.
- Non-nitrogenous fertilizers are best applied in the fall to established plantings.
- If soil is bare, plant an overwintering cover crop (e.g. rye) to build organic matter and slow soil erosion.
