USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
This legume is extremely easy to grow and will thrive in most soil conditions. It will take over most areas where it is planted, even overpowering weeds. Plant Crown Vetch in hard to reach places where you would like erosion control and some pretty color that does not need to be maintained.

Getting Started: When to Plant
Planting Grass Seed in Fall or Spring: The ideal time to plant grass seed varies by hardiness zone, but is usually in the spring, once temperatures have reached a consistent 60 F and there is no more danger of frost. Grass can be planted through the end of July but no later. If you’re planting in the fall, wait until after there have been a few killing frosts so the seeds you plant will lie dormant until the spring.
Planting as a Cover Crop or Green Manure
If you're planting grasses, legumes or clover to replenish nutrients, suppress weeds or more, we recommend planting in early to mid fall. Let the grass grow until frost. Come spring, mow before it goes to seed and then till the soil. Wait 3-6 weeks before planting new crops.
Which plants are best for cover crops?
Clover, Peas, Vetch and Rye Grass.
Planting Rates: How Much Seed Do I Need?
Planting rates vary depending on the size of the seed. A larger seed (such as a Fescue) can be seeded at 10lbs/1,000 square feet. A smaller seed (such as a Bluegrass) can be seeded as low as 2lbs/1,000 square feet. To see planting rates for each individual variety, please view the chart on the back page of this guide.

Preparing the Area for Planting
We recommend leveling the planting area as much as possible to eliminate high or low spots. Till the soil if possible about 4-6 inches deep, as the soil should be loose and clump free before planting. If your area is already somewhat bare and even, we recommend skipping the tilling process as it can promote new weed growth or unwanted grass growth. You can then add a product to help aerate your soil to improve seed germination, but this is not necessary.
Step-By-Step Planting Instructions
After your soil is prepared, apply the seed at the recommended rate. See the
back of the this guide for seeding rates. To make sure you're spreading the seed evenly, scatter 1/2 of the seed walking north to south and 1/2 of the seed walking east to west.
If you have poor soil, you could lightly apply an organic fertilizer after seeding, although this is not a necessary step for strong growth.
Many choose to cover their grass seed after planting, even though this is not necessary. If you do choose to cover your seed to help retain moisture and hold the seed in place, we recommend a maximum depth of 1/4”. You can cover the seed with topsoil, sterilized straw, or peat moss. Coated seeds such as Bermuda and Clover seeds should not be covered more than an 1/8” deep.
Water gently and regularly, keeping the seeds moist until they begin to sprout. This could mean watering more than once a day if you’re having a dry spell. Once the seeds sprout, water deeply and less frequently. This helps to ensure a deep rooted, healthy lawn or meadow.
Do not mow until your lawn is at the recommended height. This information can be found on our website at the specific product page. For most grasses, this is about
3-6 weeks after planting, but could be longer depending on growing conditions. Remember to be gentle when mowing the first few times — the seedlings will be somewhat tender.
After mowing several times, you can apply an organic fertilizer to promote strong growth, but this is not a necessary step.
It may take weeks or even a month for the seeds to grow. Be patient. If you have any questions about germination time or planting, please don’t hesitate to call us at (877) 309-7333.
