Dig In: Planting Wildflowers In A Hilly Yard

Erin, one of our long-time employees, is always up for experimenting and planting new varieties on her property in Northern Vermont. She planted a large, steep area of hear yard, about 4,000 square feet, with a variety of wildflowers,including ourNortheast Wildflower Seed Mix, plus Black Eyed Susans,Zinnias, and Cosmos.

This sloped area on Erin's property is visible from the road, so she wanted to plant something there that would create curb appeal but not require much maintenance.The results were spectacular! This hard-to-mow sloped area is now bursting with wildflowers that require little water and maintenance.

How To Prepare For Planting A Slope

We can't stress this enough: good preparation is the key to success with planting wildflowers. It is essential to remove existing growth to give your wildflower seedlings the best chance of success.

Clearing growth and preparing the soil will give seeds good contact with the soil, which is especially important to anchor them in place on a slope!

For this project, a tractor with a rototiller attachment was used with several passes to till the area, remove existing grass, and loosen the soil.

You can typically rent this type of equipment or hire a local service. You can also use hand-held rototillers, or solarize the area over time. Learn more about soil preparation techniques in our guide: How To Prepare Your Site For Planting Wildflowers

Seeding Wildflowers On A Slope

After soil is prepared, you can sow seeds! Remember, as with all plantings, be sure to follow the recommended coverage rate for the wildflower seeds you've selected. Too much seed can cause crowding, which reduces growth and flowering.

After sowing seeds, it's important to compress seeds into soil. This can be done by walking on the planting area, using cardboard or boards, or using rollers.

Compressing seeds into soil - but not burying them - is an important step that you don't want to skip when planting on a slope. It ensures good seed to soil contact. This will encourage germination, and help wildflower seedlings establish sturdy root systems on the slope or hill.

Compressing Wildflower Seed Into Soil On A Slope

After sowing seeds, it's important to compress seeds into soil. This can be done by walking on the planting area, using cardboard or boards, or using rollers.

For this planting project, Mike "The Seed Man' used a large barrel roller to compress seeds into soil efficiently.

Compressing seeds into soil - but not burying them - is an important step that you don't want to skip when planting on a slope. It ensures good seed to soil contact. This will encourage germination, and help wildflower seedlings establish sturdy root systems on the slope or hill.

Covering Wildflower Seeds On A Slope

Typically, we recommend that you do not cover wildflower seeds. However, in some instances, it can be useful to cover seed with a thin layer of straw (not hay, which will have grass seeds!)

  • When planting on seeding a steep bank where rain can easily carry seeds downhill and reposition them or clump them all together, it may help to cover them with straw.
  • If you are seeding an area exposed to strong winds, covering with straw can help keep them in place.

Watering Wildflower Seeds On A Slope

Watering is key for germination!

Give the area gentle soaking with a hose or a sprinkler as needed between rainfall. You want to keep the area moist, but not so wet or soggy that water runs down the hill. This would only wash away your seeds! A good rule of thumb for soil is keeping it as wet as a wrong-out sponge.

Keep soil and seedlings moist until seedlings are about 6 inches tall, when they will be able to survive on rainfall.

Results In The First Year

As you can see, the results were impressive! Erin, her family, and her entire neighborhood enjoyed the colorful blooms and had plenty of blooms to share in cut flower arrangements!

Happy pollinators kept the meadow buzzing and humming with life all season. After flowers passed, birds were able to snack on the seeds.

Benefits Of Wildflowers For Steep Or Hilly Yards

  • Annual Wildflowers are a great option for sloped garden beds or meadows because they sprout quickly. This makes them less susceptible to being washed away in a rainstorm. Plus, they can get to work quickly stabilizing soil and preventing erosion while perennials grow in.
  • Perennial Wildflowers are a great option for sloped areas because they grow deep, resilient root systems and grow back year after year. Once they're established, they can help prevent erosion and provide years of low-maintenance flower blooms.
  • Our wildflower seed mixes include a combination of annuals and perennials. Annuals for first season blooms, and perennials for blooms that start blooming in their second season and return each year.
  • Growing wildflowers means you can reduce or eliminate mowing your steep, sloped area! You can mow once per year for maintenance, or skip mowing altogether to allow your meadow to take on a natural look.
  • Of course, planting wildflowers will add natural beauty to your yard and provide healthy habitat for pollinators and wildlife such as birds, bees, and butterflies!

How do you make a flower garden on a slope? ›

Utilize Terracing

Should flower beds be sloped? ›

Having level beds ensures the even distribution of fertilizers and other amendments you add to your soil. As rain hits a non-level raised bed, another thing can be unevenly distributed: your growing medium itself. You can end up with some rather severe erosion issues if you don't level off your beds.

Can I just sprinkle wildflower seeds on the ground? ›

What is the best month to plant wildflower seeds? ›

September-December is the most favorable time to plant your wildflowers.

Some species will not germinate until the ground temperature is above 55 degrees F.

The correct planting depth of wildflowers is ¼ to ½ inch deep. It is not uncommon for a few seeds to remain on the soil surface. This is a good indication of proper planting depth.

Can you put down too many wildflower seeds? ›

Be sure to use only the recommended amount of seed — wildflowers do not grow well in overcrowded conditions! For even distribution, we recommend mixing 1 part seed with 8-10 parts clean, dry sand. Sow half of your seeds walking east-to-west, and the other half of your seeds walking north-to-south.

How long does a wildflower meadow last? ›

Perennial plants live for several years. Many perennial seed mixes also contain some annual wildflowers too. Annual wildflower meadows, on the other hand, are generally small seasonal features, grown from seed sown in autumn or spring. They flower in summer, then the plants die off once they've set seed.

Can you plant wildflowers without tilling? ›

Cover crop residue must decompose before seeding wildflowers, however, so fall planting is not feasible. Rake off debris and smooth the soil surface before seeding the following spring, but tilling is not recommended as it will bring up more weed seeds. Herbicides.

How to keep wildflowers from falling over? ›

Heavy-headed wildflowers may benefit from tomato cages or plastic-coated wire cages. You can also stake droopy wildflowers with bamboo and twine. Install stakes early in the season to prevent damage to the roots. Add string as the plant grows throughout the season.

Is it OK to plant a garden on a slope? ›

Planting a slope can be difficult, but there are advantages as well. Drainage is sharper, and varied planting heights and vantage points add interest. Rocks help to control erosion and add to the visual appeal. Done thoughtfully, a sloped rock garden can become the focal point of your property, just as it did here.

Can wildflowers grow in poor soil? ›

Wild flowers create a colourful display in poor quality soil. To recreate this look in your garden, replace the top 8cm of soil with some low nutrient topsoil and grow Meadowmat or seed in it.
