Seeding Small Meadows



For small areas, spreading the seed by hand (hand-broadcasting) is an effective and efficient method.

Do not plant when your soil is wet, especially in heavy clay soils. Instead wait until the soil is dry before planting. Broadcast seeding a wildflower meadow is very similar to planting a lawn but instead of using a seeder, the seed is mixed in a larger volume of a lightweight, inert material such as sawdust, peat moss, clean sand (playground or builders sand) or vermiculite. It does not matter what carrier you use; whatever is most readily available to you.

Follow the steps below to ensure a successful meadow planting.

Step 1: Mixing the Seed



Seed Mixing

When you are ready to plant, start by thoroughly mixing the seed into a lightweight, inert material such as sawdust, peat moss, or vermiculite that has been dampened only slightly so the seed will stick to it. The seed will literally disappear into the inert material. This will serve as a carrier for your seeding and it will help you to see where you've sown the seed. For every 1,000 square feet (92.4 sq. meters) to be planted, fill an 18-gallon (68.14 L) plastic storage bin to within 3 inches (7.5cm) from the top with of any one of the “carriers” described above (a Rubbermaid bin works well.

Dampen the carrier with water, just until it is slightly damp to the touch. The water is necessary so the wildflower seeds stick to the carrier which aids in even seed distribution.

Step 2: Broadcasting the Seed



Hand Broadcasting

When your seed is thoroughly mixed, divide the mixture into two equal sized portions. Then, hand broadcast one half of the seed/carrier mixture over the entire site (i.e. in a north to south direction). Then hand broadcast the second half of the mixture over the site; walking perpendicular to the direction you seeded the first half. This “cross pattern” seeding ensures even seed distribution.

Step 3: Raking



Raking

Gently rake the area so that the seed is lightly covered with soil (about 1/8 to 1/4 inches deep).

Step 4: Rolling



Rolling

Roll the site with a lawn roller to firm the seed into the soil and ensure good seed to soil contact. If your site is wet, wait until it is dry to avoid soil compaction. If you do not have access to a lawn roller, it is just as effective to walk over the area, making sure to cover the entire space. Wildflower seeds require firm seed to soil contact for good germination.

Step 5: Mulching



Mulching

Next, mulch the site with approximately one inch (2.5 cm) of clean, weed-free straw or peat moss. This will help to hold in soil moisture and increase germination. This is particularly helpful on dry, sandy soils and heavy, clay soils. The mulch should just cover the soil surface, not bury it and some soil should be visible through the mulch. If you are seeding a steep slope, hold the mulch in place by staking straw erosion control blankets that are made up of two layers of a photodegradable plastic with straw placed in between the layers. Erosion control blankets have one half to one inch openings which allows for unimpeded wildflower seedling development. Secure theses blankets with landscape staples placed at one to two foot intervals.
Never use field hay as it contains innumerable weed seeds!

Step 6: Watering



Watering

If you have installed your seed in the fall, you will not need to water at all. Spring seedings will require regular watering to stimulate germination. Use sprinklers on larger areas. Watering daily for the first six to eight weeks after planting encourages greater germination and seedling survival. After eight weeks, water only if it does not rain for a full week.

Water in the morning for 15-30 minutes or just enough to keep the soil moist. Try not to water in the late afternoon or in the evenings as this can encourage fungal diseases. Also be cautious of over-watering, especially on heavy clay soils that retain moisture.
