June is a good time to evaluate your lawns for areas where turf may be better off replaced by groundcovers. Mowing season is in full swing since warm-season grasses are growing like gangbusters; but if your turf is declining or just plain bare in spots, it could be due to too much shade created by the tree canopies above. Groundcovers can fill in those exposed areas that otherwise might get overrun with weeds. And since many groundcovers are evergreen and pretty low maintenance, these make an excellent fill in for turf-challenged areas.

While the cool, fall, weather in October makes for ideal planting conditions for groundcovers, if you just can’t wait until fall, shady area groundcovers can still be planted in June as long as you can make sure they are well watered throughout the rest of summer. Shaded areas in the landscape are less stressful during summer heat than sunny areas, so while we have listed groundcovers for multiple sun exposures, it’s not recommended to plant groundcovers now in your sunny areas. Mulching the shady areas you do plant in, will help with moisture retention which will boost your success in planting during the heat.

Below are a few ideas for plants you can use as groundcovers. Groundcovers don’t always have to be low-growing. Big ferns can make a shady haven in your landscape and agapanthus can make a striking focal point in a shady area that might otherwise be drab. Do some research on the following plants, or check out our plant finder tool, and then bring in your wish list so we can show you where to find the plants at Rainbow Gardens.

Tips for Planting Groundcovers Under Trees

Remove all weeds and turf from area to be planted.

  1. Loosen soil using s turning fork to lessen disturbance of roots under trees. Try to avoid severing any roots larger than an inch in diameter if possible.
  2. Mix in 3-4 inches of organic matter (compost, peat moss, etc…) into your native soil to make a suitable bed for your groundcovers.
  3. -Plant as deep as soil balls are tall, and water thoroughly (adding a little root stimulator helps your groundcovers get established)
  4. Apply at least 3” of mulch and keep area well-watered throughout summer, especially during times of drought.
