Regreen - Cover Crop

Regreen - Cover Crop


Regreen™ is a short-lived perennial wheat/wheatgrass hybrid that produces a sterile plant. Regreen™ is a highly versatile temporary cover crop that can be planted in either spring or fall in medium to dry soils.  Use 10-60 lbs per acre if seeding with native seed, or 90-120 lbs per acre if seeding the cover crop alone.

For our pre-designed Seed Mixes of 1/8 acre or less, we include Regreen as a temporary cover crop at no additional charge.

* please note, for large orders of many lbs., we need to charge actual shipping costs rather than our $5 minimum. We will contact you with this shipping quote when we receive your order.

5 Questions asked on Regreen - Cover Crop

Q Wendi • November 1 How quickly do seedlings germinate? How tall does it grow if left alone? Does it die if mowed?
A Prairie Moon • November 3 Germination time depends on when the seed is planted. If sown in the late fall or while the soil is frozen, the seed will lie dormant until next spring. If allowed to grow fully, it will reach 3-4 feet in height. Mowing will not kill it right away. However, repeated short mowings would kill it. Additionally, since it is sterile, the Regreen will fade out over time.
Q Gail • September 20 How does it work with the seed mix? Do you put it down at the same time? Do you mow it? and when? Thanks.
A Prairie Moon • September 20 For all of our pre-designed Seed Mixes, the 500 sq ft, 1000 sq ft, and 1/8 acre mixes come with the Regreen Cover Crop, packaged separately, from the wildflower and grass seed. If you choose to plant it, yes, seed it at the same time as your Seed Mix. If a fall or frost sowing (Oct -March), the Regreen will germinate in the spring with the rest of the natives. Yes, mow it down with the rest of the site. Mow the entire site that first growing season when plants (native or non, cover crop or not) is reaching a stage where they are shading the ground and/or wanting to flower and set seed. This may be 8-12"; mow back to 5". Repeat this 1st season mowing as often as the site needs. The Regreen is sterile, short-lived so will not come back but serves its purpose of preventing possible erosion, and/or marking the planting site.
Q Johanna • January 14 Is this seed untreated and non-GMO?
A Prairie Moon • January 15 We do not treat Re-Green with anything. And it is NON-GMO. It is winter wheat which is cross pollinated with slender wheatgrass. There is absolutely no genetic modification to the plant.
Q Eric • October 15 I'm planting my tallgrass prairie mix on flat ground and not worried about marking the site or erosion. Does Regreen help crowd out potential weeds that might interfere with the establishment of my mix, or would it make no difference if I used it or not as far as that is concerned?
A Prairie Moon • October 15 Hi Eric. Yes, you are exactly right. The ReGreen can help with erosion and will mark your planting site as it grows first and fast, but another reason we put it in our small area seed mixes free of charge is to combat weed pressure in that first growing season. You don't have to sow the ReGreen if you feel you have a really clean soil (very little weed seeds) and not much surrounding weed pressure.
Q Sue • July 24 If I sow Regreen seed in the fall, will it survive a Zone 3 winter?
A Prairie Moon • July 26 Hi Sue, If you sow the seed in the late fall (after a few hard frosts), it will sit dormant in the soil, and then germinate the following spring. What you want to avoid is planting it in the early fall and not giving the young germinated seedlings enough time to prepare for winter.
