What is the fastest growing ground cover you can walk on?
Thyme Leaf Speedwell (Veronica oltensis) is quick growing, durable, and easily a garden favorite when it comes to groundcovers you can step on. Creeping thyme is a versatile groundcover that serves multiple purposes in the garden. Its low-growing habit and dense foliage create a mat that effectively suppresses weeds, while its delicate purple flowers add a burst of color and attract pollinators.
What kills weeds but not ground cover?
If you have broadleaf weeds, hand pulling or spot treating with roundup for post emergent control is about the only option. Broadleaf weed control products cannot be sprayed over the top of ground covers as they are broadleaf plants and will likely be harmed as well. Most homeowners see flowering broadleaf weeds in the spring and reach for the herbicide. However, when it comes to perennial broadleaf weeds like dandelion, early to mid-fall is the recommended window for spraying.
