Comfrey--Symphytum officinalis Comfrey can be grown and it's leaves harvested several times a season from permanent plants in your bed; or, it can be grown, pulled-up and laid out to wilt and rot as a mulch. It can be used in several ways: 1)- One way is to harvest the leaves and make a "tea". The liquid is most often used as a tomato food, but can be used to feed a variety of plants including runner beans. 2)- It is an excellent compost starter and adds nutricious enrichment. 3)- If you are planting middle or late spuds put the leaves into the furrows before planting. 4)- Use the wilted leaves as a mulch around toms and potatoes. 5)- Another way is to pull-up the whole plant and use that directly on or in the earth. You may want to remove the roots to be sure that they do not take hold again. Making Comfrey "Tea": What you need is a barrel or some type of container, fill it with leaves (and stems if you want), top off with rain water or tap water that has stood for more than 24 hours and let it stand for 4 or 5 weeks. * NOTE-this may smell like sewerage, so keep it at the furtherest corner of your property. Making a Permanent Bed: Comfrey does really well in a sunny or partially shady place. Choose an unimportant piece of land that is out of the way to make the bed. Dig your soil and make it loose so that it's roots can easily grow downwards. You can plant seeds or buy little plantlets to get started. Sow them into individual pots at home or plant them directly into the bed that you have prepared. Planting times are March-May and September. Plant them about 2 feet apart. If your soil is chalky, correect this by adding some acidy components like compost for instance. You should not harvest any the first year, but the second year is when it will really let you see what it can do. You should easily get three harvests per year...and a fourth one if it's a good season.
