Most wildflower mixes will need a full sun location. To get started, pick a location that gets steady sunlight and till the soil using a shovel. A rotary tiller will save time if you plan to plant a large area. 

If the soil is very dense, mix in some sphagnum peat moss, composted organic material (you can easily create your own organic mulch by composting old leaves and lawn clippings) or use a premium garden soil complete with organic material, sphagnum peat moss and fertilizer.

Tip: Be sure to wear work gloves, sturdy shoes and other protective clothing when working on your new garden.

Select a Seed Mix

Wildflower mixes are made up of different colored annuals, biennials and perennials, and most are designed to grow in full sunlight. Read package directions and pay attention to instructions for planting, such as spacing, thinning if needed and mature height. Many will bloom better the second year after sowing.

Most packaged wildflower mixes include growing media and fertilizer. 

Here are some flowers commonly found in wildflower seed mixes:

  • Alyssum
  • Amaranthus
  • Blanket flower
  • Calendula
  • California poppy
  • Chrysanthemum
  • Coneflower
  • Cornflower
  • Coreopsis
  • Cosmos
  • Crimson clover
  • Delphinium
  • Painted daisy
  • Prairie aster
  • Prairie blazing star
  • Purple Prairie Cover
  • Sweet alyssum

  • Select an area that drains well with full sun. Weed the area and rake smooth.
  • Sow seeds according to the package instructions. Some seeds need to be soaked in water before planting.
  • Cover lightly with soil, a mixture of soil and sand, or decomposed granite. Don’t cover seeds that need light to germinate.
  • Water with a light mist after planting.
  • Water the seedbed daily, keeping it moist until seeds have germinated. Then water every other day.
  • Thin plants growing too closely together and remove weeds regularly.
  • Cover seeds or seedlings with row covers or burlap to keep them from washing away or being flattened from hard rain. Shade cloth protects tiny seedlings if the sun gets too hot.
How to Care for a Wildflower Garden

Water frequently to get mix established. Allow up to 21 days for germination. 

During the growing season, apply an organic fertilizer made for flowers. 

Encourage beneficial predators such as ladybugs, lacewings, flower flies and praying mantises to provide natural pest control instead of applying pesticides. Learn more about beneficial insects.

Be familiar with the flowers in the seed mix, so that you can identify weeds and prevent them from becoming a problem in your garden.
