I have 20 wintergreen variety boxwood plants purchased to use in my foundation in front of a porch. They are taller than I thought new plants should be and thin. Should I prune heavily and is it time for that now? Can I keep them below 3 1/2 feet tall, since my porch floor is that tall.
If I prune them and place in the foundation planting (about 3-4 ft apart?) how often will I need to prune them to keep this size?
