Meadowscaping in Tennessee: How to Turn a Flower Bed Into a Living Meadow
Meadowscaping is simply replacing high-maintenance lawn or flowerbeds with a dense polyculture of native perennials and grasses that fill in‚ self-seed‚ and mostly take care of themselves after the first couple of seasons․ Well-planned meadow beds require only once a year mowing (as opposed to weekly for a lawn)‚ use a fraction of the water‚ and support pollinators from March to October․ This is not a poppy-strewn field whisked away by some invisible hand but a carefully cultivated plant community‚ apparently without effort․
People realized they were spending their whole weekends trying to achieve a green lawn that wasn't providing anything to the bees‚ or the birds‚ or improving the health of the soil․ A meadow bed flips that equation․ You do more work up front‚ clearing sod‚ building up soil‚ and deciding on your species mix‚ and less work every year after․
Why This Works So Well in Tennessee
Most of Tennessee lies in USDA planting zones 6b through 7b‚ with 6a in higher elevations of the Smokies and 8a near Memphis․ That's good news for meadowscaping․ Most of the following plants are hardy throughout the range‚ and indeed‚ our clay-heavy soils‚ humid summers‚ and cold-but-not-brutal winters are better suited for prairie and meadow natives than for a pampered lawn․
One thing to watch for is drainage․ Much of Middle Tennessee is on a clay subsoil․ Although coneflower and black-eyed Susan can cope with clay soil‚ they hate standing in water all winter․ If your site puddles after a rain‚ try mixing compost or coarse sand into the soil‚ or consider making a slightly raised planting bed․
Site Prep: The Part Nobody Wants to Talk About
One of the most common causes of first-year meadow failure is skipping soil preparation․ If you are converting an existing lawn‚ you have two options: smothering the grass with several layers of cardboard and mulch for 6-8 weeks during the summer or mechanically stripping the sod away․ Herbicide works too‚ but because most people going through the trouble of meadowscaping want to cut down on chemical inputs‚ that would defeat the purpose․
In Tennessee‚ the best planting time is fall (September through mid-October)‚ as at that time air temperatures are cooler‚ soil temperatures are still warm‚ and many of these species require a cold winter to produce strong spring growth․ Spring plantings also are acceptable‚ but water more during the first hot spell in June․
The Core Plant Palette
Yarrow (Achillea millefolium) is a typical meadow plant‚ flowering during most of the growing season‚ tolerant of thin‚ dry soil‚ and spreading by seed and shallow rhizomes․ Spacings of 12-18 inches (30-46 cm) are generally appropriate‚ with flowering plants expected by the second year on average․ White‚ soft pink‚ and yellow flowers appear on the ferny foliage that remains attractive even when out of flower․
Purple Coneflower (Echinacea purpurea)‚ including the yellow colored variety‚ provides the bulk of pollen available to pollinators in June‚ July and August․ Being true taproot perennials they do not like to be disturbed and should be planted with care․ Give them full sun and average soil; rich‚ over-fertilized ground actually makes them floppy and short-lived․
In American culture‚ goldenrod (Solidago spp․) is blamed for pollen allergies‚ but it is truly the pollen of the completely unrelated ragweed‚ which has a different structure better suited to wind pollination‚ that is light and powdery․ As one of the few available major sources of nectar in September and October it is a favored nectar plant of migrating southward monarchs․
The most often abused plants in a meadow garden are the Carex‚ commonly called sedges․ Otherwise‚ the area is bare soil‚ or becomes weeds‚ between the flowering perennials․ Pennsylvania sedge is a tolerant shade plant‚ and some tough Carex are tolerant of full sun and can be installed as plugs 12 inches (30 cm) apart that will seam together in two growing seasons․
The fastest plants to germinate from seed are probably the Black-Eyed Susans (Rudbeckia hirta)‚ which may flower in their first year․ However‚ as plants live only 2 to 3 years at most‚ and self-seed sufficiently well for any patch to be considered permanent‚ they are effectively permanent additions․
Blanket Flower (Gaillardia) wants the driest‚ sunniest‚ worst soil in your yard and rewards you for it with red-and-yellow blooms from early summer straight through frost․ It's the plant to put in that awful strip along the driveway where nothing else survives․
Daffodils (Narcissus) are not native‚ but worth having for their very early bloom‚ before almost anything else wakes up‚ in late February and March‚ and for the fact that deer ignore them․ Plant bulbs in the fall‚ in drifts between the crowns of perennials‚ six inches deep‚ so that they pop up before the meadow greens up․
TN Nursery carries all of these as established perennials and bulbs․ That makes a difference for meadows‚ which when grown from seed can take three full seasons to appear intentionally planted․ Using plugs and potted perennials gives the garden a sense of perceived fullness in its second year․
Maintenance: What "Low Maintenance" Actually Means
Year one still requires water and weed control while the roots get established․ Don't let anyone tell you meadowscaping is zero-effort from day one․ By the second year most of these species need supplemental watering only during particularly extended dry spells․ The one major maintenance task is the annual cutback of the previous year's growth done in late February or early March before new growth appears․ The previous year's growth is left up all winter as insect habitat and to provide seeds for birds․
Do not deadhead in fall: those seed heads are exactly what feed goldfinches and native bees during the winter‚ and they are the difference between a meadow that continues to reseed itself and one that you need to replant every couple of years․
