This hardworking combination of field peas and oats quickly improves the soil with nutrients and organic material, while helping supress weeds. The mix is also perfect for conditioning areas being turned into gardens, such as lawns and vacant lots. Pea plants fix nitrogen and condition the topsoil, while the flowers and bees and other beneficial insects. Oats hold nitrogen, provide organic material, and suppress weeds. When sown in the fall, peas and oats grow heartily in the cool weather but are killed by the cold temperatures of winter (USDA zones 7 and colder) and won't regrow in the spring. The dead plant material provides a wonderful winter mulch that helps prevent soil erosion and is ready to be tilled into the garden as soon as soil can be worked in the spring.

Cover crop: Soil builder peas & oats

5 out of 5 stars Feb 27, 2019
It works! I took over the management of a vegetable garden at my church and found the soil to be severely depleted of nutrients and void of life. I sowed Botanical Interests Soil Builder Peas & Oats Cover Crop and let it do it's thing and when I turned it in (about 3-4 months later) the soil was rich and alive with life! I'm a new fan of green manures, especially the Soil Builder Peas & Oats! Thanks for a great product.

Works for raised beds too

5 out of 5 stars Apr 2, 2020
We have raised beds, so putting in a cover crop can be awkward to deal with in the spring. You just can't stick a roto-tiller up there and work everything in. We planted the Soil Builder Peas and Oats in the fall, they grew for a few weeks, then died back with the hard frost. This was as stated and as expected. Now we can easily turn the soil with a potato rake and work the remains of the cover crop into the soil. Love this stuff! We would recommend it for anyone with raised beds who isn't sure how to take advantage of cover crops when your soil is a foot or 2 up in the air. Gardens on the ground will love it too.

Did a great job

I am so pleased with this cover crop. I am prepping my beds for planting and cannot believe the difference in the soil texture. It is nice and loose - perfect for planting seedlings in. This only year 3 of using this area. It was lawn with lots of clay I the soil. I am very pleased with the results.

Excellent Winter Covercrop

5 out of 5 stars Aug 3, 2020
This mix works great all through winter at 4500 ft in Southern AZ mountains. Shows some damage from freezes and snow, but recovers quickly. The plants blanket bare ground, the roots hold and enrich soil, and when you cut it before spring planting, it dries into great mulch. Easy to seed. Gets by with seasonal rain (if it comes.) Plus, you can eat the pea shoots.

A little disappointed

3 out of 5 stars Jan 27, 2021
I bought a couple packs of these to use in a small bed. It is now almost February and we've had more below zero nights than most years and these are all still alive. So I have to say I'm a bit disappointed that they never died as indicated on the package. So I unfortunately won't get the full benefit of growing them.

Cover crop

Disappointed. I live in North Dakota. Very windy. Very few plants grew from sowing the seeds. I purchased more than enough to provide a nice cover crop. It was a waste of time and money.

A Miracle Worker

These are SO easy to grow, and do absolutely amazing wonders to the soil. Simply scatter them on the ground, or very lightly bury them, and they are 100% guaranteed to come up and start growing. As these are Nitrogen fixing crops, they put Nitrogen back into the soil for the next thing that you plant after. It definitely works on that front. Highly recommended for those seeking to amend or improve their soil(s).

Soil Builder mix

These seeds did well in my small patch, and i even got peas in early spring! Definitely a good cover crop to help enrich the soil. I will probably plant again this fall.

Not sure

I purchased th Pea and Oats soil builder, and added it to my beds in the fall after harvest. I didn't notice if anything grew...here's hoping!
Christine from AL
Owner Response: Hi Christine, We recommend sowing these about 6 weeks prior to your average first frost to ensure they have good soil temperatures to germinate and enough time to grow in fall to be beneficial. We hope that is helpful. Happy gardening!

only the peas survived

4 out of 5 stars Apr 18, 2022
I planted these in early spring as soon as the soil was workable. At first everything sprouted up and did well but as soon as we had a night time freeze come through it killed off the oat seedlings and only left the peas. I partially blame this on maybe my over eagerness to plant, but also the weather patterns in spring are very flip-floppy between warm and freezing these past few years so i also think that had something to do with it. Still a great product in itself, maybe better luck next time for me.
