Care
- Water: Comfrey prefers consistently moist soil but isn’t too picky about watering. Just make sure the soil doesn’t dry out completely. It’s a tough plant, but like any other, it thrives best with a regular water supply.
- Light: This plant enjoys full sun to partial shade. It can handle various light conditions, but more sun usually means more flowers and a healthier plant overall.
- Soil: Comfrey isn’t too demanding when it comes to soil. It grows well in a range of soil types, from sandy to clay, as long as it’s well-drained. Adding compost can help boost growth and keep the soil rich.
- Temperature and Humidity: Comfrey is quite adaptable and can tolerate a wide range of temperatures. It prefers temperate climates but can handle both cool and warm weather. It’s a hardy plant that can survive through winter in many regions.
- Planting & Growing: Comfrey is best planted in spring after the last frost, but it can also be grown in autumn in milder climates. You can start comfrey from seeds, root cuttings, or transplants. If planting from seeds, sow them about 1/2 inch deep. Comfrey grows quickly and can spread, so give it some space—about 2-3 feet between plants is ideal.
- Pruning: Pruning comfrey isn’t complicated. It’s good to cut it back a few times a year, especially before it flowers, to encourage more leaf growth. The leaves make excellent mulch or compost, as they’re rich in nutrients. Cutting back the plant also helps keep it from spreading too much and becoming invasive.
Common Pests
Comfrey is generally pest-resistant, but spider mites, mealybugs and snails take a liking to its large, juicy leaves. If you notice any, you can use natural pest control methods like setting up beer traps or using organic slug pellets.
