Prairie gardens can be described as natural, native gardens. They are pleasing to look at because they include flowers, grassy textures and you will always see wildlife. Subconsciously, the human eye understands that it is looking at a healthy ecosystem and that these plants grow where they belong. Prairies are used for organic, natural pest control because its design attracts, deters and takes care of every possible problem known to that area.
To get a prairie right, you have to ideally copy what grows there naturally.
The latest trend in organic, perma-cultural, regenerative and even mono-crop farming includes environmentally friendly pest-control methods – which are in fact as old as the hills. Biological pest control methods involve planting wild flower strips (let’s call them bug highways) around their crops. The plants attract pollinators and beneficial insects to take care of pests. Herbs are especially successful in both attracting the right insects and yet deterring pests. Thus rendering the use of pesticides useless. As pesticides impact on bees negatively (to name one terrible side effect), planting prairies only makes sense.

A good tip is to plant 1 third grasses and 2 thirds perennial flowers. These plants should be planted in clumps of 7 each (i.e 7 grasses next to 7 flowers of one kind and also 7 of another – and repeat as you i.e plant your border around the veggie patch). Include bulbs for your under-planting and you will have a great-looking mini-prairie in no time. Look at your nearest botanical garden. What mid-size flowering perennials and ornamental grasses did they include there? Those are good choices to go on the list. Make sure your soil is well draining and fertile by adding compost and mulch. Adopt no-dig principles and let the mycorrhizal fungi settle.
Prairies are used for their many benefits: mainly-indigenous prairie gardens are mostly maintenance-free, attractive and highly beneficial in terms of inviting back wildlife and restoring ecosystems. They act as mega supermarkets to pollinators and birds, reptiles and other critters that was part of the once natural balance.
Indigenous wildflowers, grasses and bulbs are conditioned to thrive where they are from and thus have lower water and feeding requirements, but higher resistance to disease and pests. They cause soil improvement, prevention of erosion plus higher yields of food crops.
Prairies are used for farming and food gardens where natural methods are practiced. Purely indigenous is not where the focus should be but rather everyone lives by the golden rule of diversity above all else. If great diversity can be achieved through indigenous choices, that is of course best and also the main idea behind permaculture. We can only benefit by honoring this all-inclusive method, and our planet’s health will be restored in no time.
