About Comfrey as a Living Barrier
Standard Barrier (18" spacing)
Our recommended standard spacing of 18 inches between plants creates an effective barrier
that will fill in nicely within 1-2 growing seasons. This spacing works well for most garden
applications where you want to create a clear boundary.
At this spacing, you'll need approximately 0.67 plants per linear foot.
Dense Barrier (12" spacing)
For a more immediate barrier effect or for areas where you want to maximize the blocking
potential of your comfrey plants, consider the denser 12-inch spacing. This creates a
thick hedge-like barrier that fills in quickly.
At this spacing, you'll need approximately 1 plant per linear foot.
Benefits of a Comfrey Barrier
- Natural Rhizome Blocker: Comfrey's dense root system helps prevent the spread of invasive plants
- Nutrient Accumulator: Creates a nutrient-rich boundary that benefits adjacent plants
- Pollinator Attractor: When in bloom, attracts beneficial insects to your garden
- Wind Break: Provides protection for more delicate plants
- Harvestable Resource: Unlike most barriers, you can harvest your comfrey barrier for mulch, compost, or tea
