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).

Step-by-Step Wildflower Seed Planting Instructions

  1. Check for your last frost date and plant after this has passed. Choose a spot on your property that gets 6 or more hours of direct sun a day unless you are planting seeds for shade.
  2. Prepare your soil by clearing the area of all existing growth. Simply dig up everything that is growing, turn the soil and rake the area flat. If this is an area that has never before been gardened, you may need to till the area up to remove growth.
  3. Mix the seeds with sand* for better visibility and scatter the seeds directly on top of the soil. If you are sowing a larger area, we recommend using a seed spreader; if not, you can sow by hand.
  4. We recommend lightly compressing the seeds into the soil, making sure not to bury them. You can either walk on them, use a board or if you are sowing a larger area, rent a seed roller.
  5. Water so that the soil is moist, not soaking wet, until the seedlings are about 4-6" tall. After that, the seedlings will survive on natural rains. If you are experiencing very dry weather, we recommend watering occasionally.
