Fill in the space between pachysandra plants with 2 to 3 inches of mulch, such as bark or wood chips. Mulch shades the exposed soil, preventing many types of weeds from growing.
Typically grown as an evergreen ground cover in shady areas, under trees or on slopes, Pachysandra spp., commonly called pachysandras or spurges, grow well in U.S. Department of Agriculture plant hardiness zones 4 through 9, depending on the variety. Pachysandra has shallow roots, so weeds — which also have shallow roots — compete for valuable nutrients and water found in the soil. Getting rid of the weeds likely requires persistence on your part, but by using more than one control method, you can get rid of nuisance weeds so that your pachysandra thrives.
Manually pull weeds, doing so slowly so that you get all the roots. If you yank too hard, the weeds break, leaving the roots in the ground. Pulling weeds is easier when the soil is moist. Pulling is one of the best methods to control weeds, especially broadleaf weeds.
Grow pachysandras close together so that they are planted 6 inches apart and in staggered rows. This allows the plants to fill in the area quickly, choking out weeds in the process. Often, pachysandras are planted 1 to 3 feet apart, but this makes the area more susceptible to weeds while the plants become established.
Apply herbicides to kill weeds. Herbicides, such as one that contains fluazifop, kill grassy weeds, such as crabgrass, and do not harm pachysandra. For broadleaf weeds, it’s best to use another cultural practice to manage the weeds, but if desired, you can paint on a nonselective herbicide, such as glyphosate. If any touches the pachysandra, it will harm it. You can also use a preemergent herbicide if your pachysandra is established before weeds germinate. As with all herbicides, use product as instructed on the label.
Can you use preen around pachysandra?
Pachysandra has a shallow root system. To make sure you get all of the roots, cut through the foliage and remove the top 4 to 6 inches of soil across the area where the plants grow. Cover it with black plastic. The soil under the plastic will heat up, and the plastic will deprive the plants of sunlight and water.

Additionally, will Roundup kill pachysandra? Kill pachysandra with a nonselective herbicide, such as glyphosate. Spray the foliage with the herbicide on a dry, calm day. Reapply the herbicide in about four weeks if some of the pachysandra is still alive. Apply it carefully; a nonselective herbicides kills most plants and grasses with which it makes contact.
What can I use to kill grass & weeds in myrtle without killing it? Smother it with newspaper, cardboard or landscape fabric. Then place mulch or rocks on top. You will still get weeds, but they will be shallow rooted and easy to pluck.
Ortho Grass-B-Gon selective grass killer will kill the grass growing in your pachysandra. After the grass is eliminated, the few weeds that remain will be easier to remove. Once the beds are weed free, apply Preen weed preventer to the beds to prevent new weed seeds from germinating.
