A stretch of wildflowers planted in your yard can add a natural feel around your home. Wildflower seeds typically come in a mix that includes perennial, biennial and annual flowers. Your perennial and biennial flowers will reappear for years to come after planting, and you can add new annuals to your wildlife patch each year to rejuvenate any empty areas that appear. Most wildflowers grow in full sun, but sometimes you can find special seed mixtures for shadier areas of your yard.
Select an area for your wildflower patch after the last frost in spring. Choose an area with well-drained soil that is close to a water source to make it easier to care for your plants. Choose an area with full and direct sun, unless you have partial shade wildflower seeds.
Till the area with your shovel to the depth necessary to loosen weed roots. Remove all the weeds with their roots from the planting area. Remove rocks, and rake the soil until it is even.
Add sand to your soil if it has a lot of clay, or humus if it is too sandy. Otherwise, wildflowers adapt well to most soil types.
Rake a low nitrogen perennial fertilizer into the soil, if you wish. Fertilizer isn't necessary for wildflowers, though, since they grow well under most conditions.
Apply twice the amount of seed recommended on your seed package if you want a heavier bloom in your garden area. Separate your seeds into two buckets. Mix your vermiculite into each bucket at a rate of 10 parts to 1 part seed. Combine the vermiculite with the seed well.
Spread your first bucket of seed evenly over the garden area so that it is entirely covered. Then, add the second bucket of seed to the soil evenly over the area.
Use a lawn roller or your feet to press the seeds down against the soil. Seeds should only be pressed firmly against the soil, but not covered.
Add enough water to moisten the soil. Continue to moisten the soil until seedlings reach about 6 inches in height in about six weeks.
Mow your wildflower patch after your flowers have gone to seed and the seeds have fallen on the soil in late fall. This will help to prepare your patch for new growth the following spring.
Add new annual wildflower seeds such as cosmos, poppy or baby's breath to any bare spots that have appeared in your patch the following spring.
