Cover Crops

Cover crops or green manures are becoming more and more popular in organic gardens, but they can be a bit more demanding and tricky than many gardeners care to tackle. AC Greenfix makes growing a cover crop user friendly and improves even the most overused soil including alkali soil. A short season legume that organically increases nitrogen and soil fertility while promoting beneficial bacteria growth when used as a green manure. Very moisture efficient itself, with proper inoculation research indicates it can actually improve your soil’s moisture efficiency up to 130%. Planting is usually recommended when day temperatures average about 50° and nights 30°, it can withstand temperatures as low as 22°F. The best results are obtained if plants are allowed to grow for 60-70 days, although beneficial results can be seen with only 40-50 days of growth.

But if you fail to get an early jump, don’t despair, just plant it between your rows and fertilize while you grow. Plants should be tilled in or cut off and allowed to re-grow, before seed pods begin to fill. Fall planting works well even in northern states where plants can be allowed to freeze off. Plan extra seed for use in your garden, flowerbeds and areas of lawn that need replanting.

Even better, it is not a weed. It will not invade your garden or return as an obnoxious weed. And being a fine leafed plant it will till in with ease; no big machinery is required. With all of these benefits and ease of use one would not expect 1” flowers that range in colors from white to blue and pink to purple all on the same plant to liven up your garden. While it does good things for your soil it is not intended for human consumption.

Planting Instructions

AC Greenfix seeds Inoculate Proper inoculation is essential for nitrogen production. Inoculant and instructions are included with each garden seed purchase.

Spring Planting Yields best results. Plants can usually tolerate temperatures as low as 22-26° F. Recommended planting time is early spring, 40 days prior to normal planting or more. Plant seeds 1-1½” deep every six inches. Space rows 6-12” apart.

Fall Planting Fall planting in August when moisture is sufficient or with adequate watering can yield satisfactory results. Growth is usually reduced. Allow plants to freeze off. Plant as above and allow to grow 35-40 days.

Growth AC Greenfix grows slowly for the first 30-40 days. Increased bacterial activity in the soil may contribute to germination of weed seeds already present. These can be incorporated as part of the green manure. Growth usually ranges from 18-35 inched high with plants in full bloom by about 60 days. For maximum nitrogen production, the plants should be tilled in before seedpods begin filling, about 40-60 days.

Helpful Hints AC Greenfix grows best and produces better results when planted in nitrogen depleted soil, so plant it before you spread your compost or do any other fertilizing.

It is best to plant this crop behind a cereal grain crop, if planted after a bean crop – 1/2 the height will be seen.


Didn’t get it planted as soon as you would have liked? Plant between rows to fertilize them as they grow. This works especially well with corn. Remember to clip off before seedpods begin to fill and it will grow back with sufficient moisture. Rotate your planting by planting after short season crops like lettuce and spinach. Because AC Greenfix is such a short season crop with a little planning you can get the most out of even a small garden space.
