Regreen - Cover Crop

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.

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.

We do not treat Re-Green with anything. And it is NON-GMO. It is winter wheat which is cross pollinated with slender wheatgrass (Triticum aestivum x Elymus trachycaulus) There is absolutely no genetic modification to the plant.

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.

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.

The Regreen cover crop will act as a place holder. If winter sowing your seeds right now, your seed mix will stratify over winter and germinate in the Spring. It is common for cover crops to be planted in the Spring with a native seed mix because the seeds will lay dormant until they get their overwinter period and then germinate the following Spring. By planting the cover crop (it will phase out in a year or so) that is holding the spot so no unwanted weed seeds blow in and take over the area. But if seeding in the Fall or Winter, the cover crop is not necessary but will do no harm if planted with the seed mix.

Hi Dan. ReGreen is a very versatile cover crop and could work well for that purpose. If there is evidence of Buckthorn and Honeysuckle in the site, it will more cost efficient to sow Annual Rye Grass to hold the cleared soil. A pound covers more area and costs less.

Hi Desi. If you ordered the smaller size mixes with the ReGreen included, I would sow it along with the mix. This cover crop will not affect the established natives - but the extra desirable plant growth will help prevent weed seeds from blowing in.

Hi Andrew. Regreen does not winter-kill. As long as it germinates and is able to establish a good root system before any hard freezes, it will return the following spring and continue to grow. Native seed mixes should be sown into the young Regreen in late fall; or hold off and sow the Regreen in late October/November to overwinter along with the native seed.
