Comfrey. Russian comfrey (Symphytum x uplandicum) Comfrey (also comphrey) is a common name for plants in the genus Symphytum.
Comfrey species are important herbs in organic gardening. It is used as a fertilizer and as an herbal medicine. The most commonly used species is Russian comfrey Symphytum × uplandicum ,[1] which is a cross or hybrid of Symphytum officinale (Common Comfrey) and Symphytum asperum (Rough Comfrey). Description[edit] Cultivation[edit] Comfrey has long been recognized by both organic gardeners and herbalists for its great usefulness and versatility; of particular interest is the 'Bocking 14' cultivar of Russian Comfrey.
The comfrey bed should be well prepared by weeding thoroughly, and dressing with manure if available. Comfrey is a fast growing plant, producing huge amounts of leaf during the growing season, and hence is very nitrogen hungry. Fertilizer uses[edit] There are various ways in which comfrey can be used as a fertilizer. Propagation[edit] Medicinal uses[edit] Garden Planner: The Best Way to Plan Your Kitchen Garden.

They’re divided into two groups: Cool-Season and Warm-Season with each having varieties that are hardier than the rest (these are noted by color in the chart below). First, here’s an introduction to both: Cool-Season: Most are frost-tolerant and can tolerate below freezing temperatures (some only short term). They thrive in cool weather with most seeds needing the cold temperature to germinate. Transplants should be hardened off a minimum of 7 days before planting to help them adjust to the cold weather. Warm-Season: These are not frost-tolerant and are more tender, they require waiting until the last frost date has passed.
Seedlings should be hardened off outdoors before planting. The chart below is a general guideline only, use this to determine what can be planted early and what needs to wait. Cool-Season Crops When to plant: 2 to 4 weeks before frost-free date. How to Save Heirloom Tomato Seeds.
