Comfrey belongs to the Borage family. The two most common are Symphytum Officinale (common comfrey) and Symphytum Uplandicum (Russian comfrey). These sturdy perennials are famous for their deep-tapping roots. Comfrey growing zone is in USDA Hardiness Zones 4 to 9.
Various cultures have revered comfrey for its medicinal nature. In the garden, comfrey has deep roots. It serves as a nutrient accumulator and a nutrient-rich addition to compost.
The pot's size should allow the comfrey to grow unhindered and should suit the space available. The material of the pot impacts moisture retention and temperature. This affects the health of your comfrey plant.
Comfrey roots resent waterlogging. So ensure your pot has excellent drainage to avoid root rot. Preparing the optimal growing medium is also vital. A mix of regular soil, compost, and sand often provides the right balance of nutrients and drainage.

For comfrey to flourish, the potting mix must be rich and nutrient-laden. Start with a base of quality organic potting mix, one that doesn't contain added fertilizers. To this, add well-rotted compost and a sprinkle of bone meal to supercharge the soil with nutrients. Ensure the mix is well-aerated by incorporating perlite or vermiculite.
You can purchase comfrey as seedlings or propagate from cuttings. If buying seedlings, look for healthy plants with vibrant green leaves and sturdy stems. You should take cuttings from mature comfrey plants. They should segments of the root included to encourage quicker establishment.
Mix a balanced garden soil with compost for added nutrition. Comfrey favors moist soil, so ensure your mix isn't overly draining. A 2:1 soil to compost ratio usually does the trick. Before adding the soil, place a handful of stones or broken pot shards at the base to improve drainage.
If working with cuttings, ensure they are at least two inches in length. Make a slanting cut at the base before growing comfrey in pots. If you've opted for seedlings, gently remove them from their nursery container. Retaining the soil around the roots. Plant your comfrey at the same depth it was previously growing to ward off transplant shock.

If you're growing comfrey indoors, pick a sunny windowsill. Outdoors, a shaded area will suffice for this semi-aquatic sun-lover.
Comfrey requires consistent moisture. You’ll need to keep the soil slightly damp at all times. Overwatering can be just as problematic as under-watering. So drip irrigation or self-watering pots can be great tools to maintain the right moisture level.
Organic fertilizers are your best bet when growing comfrey in containers. They respond well to a balanced feed. You should provide it through a top-dressing of compost every few months. This will supply the necessary nutrients, help retain moisture and keep the soil structure intact.
Regular pruning to ensure your comfrey plants remain productive and healthy. Trim the leaves several times a year, particularly before the flowering stage. This tends to weaken the plant.

Root rot can be devastating to comfrey if left unchecked. The best treatment is prevention. Ensure proper drainage and avoid overwatering.

Using a sharp, clean knife, cut a length of the root about the size of your thumb. Additional growing points equate to more shoots. So optimally, looking for a piece of root that has two or three buds. Plant the cuttings as you would a whole plant and water in.
Growing comfrey from seed is less common. It's easier and faster to propagate from roots or cuttings. If seeds are your only option, you can sow them directly into the potting mix. Keep the soil moist, and seedlings should emerge within a couple of weeks.
