I have used this blend all over my new property this fall to add nutrients to the soil and keep the hillside in place during the rains. It is an outstanding, fast growing mix with no grasses. Creates lots of biomass for chop and drop or compost. Most importantly, some early planting tests shows my sloped garden is filled with worms and very pliable - and it remains on the hillside. I will never ued anything else.

Silly Me : (

I didn't read enough about this product. In a hurry! It is too late for me to plant the mix here in Maine. AND I forgot to order the inoculant. I am going to save the seed and hopefully it will germinate for next early Sept. I won't forget to get the inoculant. Too early to order it now as it has a shelf life of about a year which usually means out of date in Dec. 2018.

proven year after year

I have used this as a cover crop three years in a row and always with great success. I use no till methods and sheet mulch directly over the cut cover crop in the spring. The results are truly phenomenal. I use minimal other amendments other than a little top dressing. seems like the soil gets better each year, its alive and thriving! and very few weeds as they are out competed and of course killed during the sheet mulching process.

Excellent as alway

Obviously I haven't yet planted the cover crop for winter, but the package arrived promptly and in good shape; the seed looks good.
