Can I plant shrubs during winter months?

Prof. Martin Thorne, Ph.D.Winter shrub installation offers its own challenges and opportunities for a gardener. It is a practice that I typically would not do, but it can be achieved if the conditions are right. First success starts with understanding your local climate patterns, as well as the plant hardiness zone. I have successfully planted in mild winters, especially when I followed strict protocols.
Site Selection
- Choose sheltered locations away from wind exposure
- Ensure excellent drainage to prevent waterlogging
- Select south-facing slopes for maximum warmth
Root Protection
- Use burlap wraps for root insulation
- Apply anti-desiccant sprays to evergreen foliage
- Create mulch volcanoes (6-inch depth)
Planting Technique
- Plant during thaw periods only
- Backfill with warm water to prevent shock
- Stake immediately for wind resistance
Frost heave poses the primary winter planting threat. Freeze-thaw cycles can physically dislodge shrubs from the ground. To combat this, I use deep mulch insulation around the roots. I also wrap the shrub in burlap for supplemental protection against drying winds. Check the soil once a week for signs of displacement.
Container specimens offer the most planting flexibility in winter. They are also better able to adjust to transplant shock through their established roots. That said, I still don't like to risk planting below 25°F (-4°C). My potted hollies were able to survive a January planting due to good insulation. Bare-root plants will rarely make it through the winter.
After planting is through, put the plant under close vigilance. Inspect for any root exposure when heavy snow or rain falls, water only during thaw periods when the soil can absorb moisture. Fertilize in spring to minimize the forcing of soft growth; winter-installed plants will certainly need special attention in spring.
