Good-Bye Grass, Hello Pollinators

If you are ready to give up some or all of your lawn in favor of more environmentally sustainable and pollinator-friendly options, there are several alternatives to turfgrass including low-growing wildflowers, clovers, and fescues.

We know traditional lawns are not good for the environment. That green, carpet-like grass that blankets much of suburban North America requires frequent mowing (fuel, time, pollution), gobbles up water, and sends hazardous runoff from chemical fertilizers to our waterways.  

Topped off with herbicides and devoid of flowers for pollinators, we’ve created massive green wastelands.

Lawn seems so practical and pretty until you weigh the environmental costs.

I realize most lawns will not go away in this century but just think of those millions and millions of sterile green lawns that could become life-sustaining eco-corridors just by ditching the chemicals and planting more diversely.

For me as a gardener, it’s been a personal evolution over many years but these days my garden choices are guided by what’s best for the beneficial insects. That one objective leads to flowers, food, beauty, and sustainability.

Plus, life is just too darn short for frequent lawn care.

Faced with a lot of grass lawn at our current home, I am always looking for more low-care plant options that support wildlife.

Keep reading to hear what I planted and how it’s going.

Getting Real About Replacing Lawn

Converting lawn into a pollinator haven is not as simple as sprinkling some seeds.

Contrary to popular belief, you cannot just let your lawn grow out and think you will have wildflower meadow.

Everything depends on what you’ve already got and your growing conditions.

If you do want a meadow instead of just low-growing wildflower ground cover, the new book Lawns into Meadows by Owen Wormster walks you through the transformation process.

And neither can you toss wildflower seeds on top of grass lawn and think you’ll be swimming in flowers.

Seeds Need Soil Contact to Germinate

Wildflower seeds need contact with moist soil to germinate, and, if any do make it, turf grass will out-compete them. That’s the nature of the beast. Traditional lawn grasses are chosen specifically for this quality.

To successfully replace some or all of your lawn requires

• Choosing the right seeds for your climate and growing conditions.
• Proper soil preparation including removing all other plants and roots in the planting area—in the least harmful way possible.
• Some ongoing maintenance.

It’s also important to let go of perfectionism and focus on the good you are doing. And once you see the life it brings, an appreciation for true natural beauty follows.

This means working with nature, not against it: tidy is for houses, not gardens.

How I’m Replacing Lawn With Wildflowers

After researching various options, I decided to sow an alternative wildflower lawn mix (details below) in parts of my yard where I have been pulling out an invasive ground cover (creeping Jenny | Lysimachia nummularia).

While the urge to purge the entire lawn is real, I want to test small areas first to be sure it’s worth the time and money to seed larger areas.   

I’ve got progress pictures (below) and will keep updating it as we move through the seasons.

The big test will be to see what grows after the winter. I’ll be thrilled if it does continue growing.

Alternative Lawn Progress Report

1Soil Preparation

The instructions say to start the seeds in late spring but we had a cold snap in June so I held off until the end of June.

To get started, I cleared the sowing area of plants and roots and put down a layer of top soil.

Many wildflowers mixes do best in poor quality soil. I have lots of that so I did not add any compost or manure.

We got a massive rain storm the same day I sowed the seeds. I was worried they would wash away.

2Week One

Germination conditions were clearly perfect because this is how it looked just a few days later. Lots of seedlings!

The straggly looking plants among the seedlings are some lavender plants I transplanted from another part of the garden. The purple flowers are hardy geraniums and not part of the mix.

I hand-watered the entire sowing area daily if needed to keep the soil moist for the first two weeks.

There were a few bald spots so I added some extra seeds to those areas.

2Week Two

By the second week everything was filling in nicely.

3Week Six

At this point the seedlings are young plants, about 8-inches tall. I can tell there are several species growing but so far only the white alyssum is flowering.

This area is prone to weeds and a few have shown up (that are prominent in my soil) but the alternative lawn mix is winning so far.

This is how it looks close-up.

The seed mix contains perennials, biennials, and annuals so theoretically there should be some self-seeding and new growth in spring.

And that’s it so far.

I’ll give an update here as soon as I have one.

If it works, I will definitely continue seeding more areas of the garden.
