Q. pachysandra

I have pachysandra and don’t really care what variety it is. I do know that it propagates very easily, growing like strawberries do. My pachysandra grows out beyond where I want. How can I contain it? I had thought to build a barrier. My experience with Japanese knotweed, which grows to a depth of 4 feet, is not one I wish to repeat.

Yes, that should be good. Happy gardening!

I have found that typically a small barrier, such as garden edging, and a yearly manual edging with a sharp spade to cut the runners is enough to keep the pachysandra in check.

Thank you!
Is a four inch barrier sufficiently deep?

Q. Kill Grass

I have unwanted grass growing through an area of pachysandra ground cover. I do not want the grass. How can I get rid of the grass without hurting the pachysandra?

While you can try spot treating it with things like boiling water, vinegar, or Grass-B-Gon, it will also kill your ground cover if it touches it. One way to avoid this is by using some type of shield to cover the plants you wish to keep. Since this is not an easy task, you may need to resort to hand pulling the grass instead.

Q. pachysandra

I am growing pachysandra (Japanese spurge) in a shady area at 4, 000′ elevation in CA. The planting is about five years old and the plants are getting tall, sparse and leggy in appearance. Should I trim them back or pull and replant? If I need to replant, I need some ideas. I have tried ajuga and thyme but they fail to recover after the winter snows. Thanks!

If they are getting leggy there, that means that the shade is too deep. You can try trimming it down to reinvigorate, but eventually it will get leggy again. Is there anyway you can thin out the canopy over it? Even a little bit of judicial thinning of the branches overhead will allow a little more light in without disturbing the shaded feel of the location. With just a little more light, the plants should be fine there after trimming.

Q. I’m considering planting pachysandra as a ground cover

We have a new patio with a slope around it and need something besides pine straw (live in S.Carolina). The area receives some morning sun, then filtered sun (through big trees), then shade in the afternoon. I’ve had pachysandra before and loved it.

Can I control its boundaries with a 5″ high composite plastic edging? Does it become invasive? I remember it overtook some liriope in a bed with some perennials in our garden area in Virginia where we lived two years ago.

Thanks for your help!

Controlling Pachysandra, this is the question!
Keeping an eye on the plant and keeping it controlled can be an issue.
It's roots are invasive and plastic edging may slow it down but it will find it's way around, under or over it.
Here are a few links.

Q. pachysandra infected with gout weed

I have a bed of nice pachysandra which has been infected with gout weed. I have tried weed killer but it also kills the better plant. Is there any way to kill this without weed killer? Could the pH solve the problem, as I understand pachysandra likes acid soil. I don’t know about gout weed. Thank you.

Really the only way to control goutweed (aka: bishop's weed) is to hand pull it and mulch around the area where it keep popping up. You could try using Roundup, or even boiling water, and spot treat the goutweed while covering your pachysandra with a shield of some kind (like cardboard). Still the best way would be to simply pull or dig it up.

Q. fertilizing pachysandra

Is it wise or unwise to use 10-10-10 on pachysandra in the fall and spring? Is it wise to fertilize pachysandra at all? Should it be done in the fall or spring or both? What type of fertilizer? Will fertilizing harm the plant?

Answered by

You can fertilize your Pachysandra in the spring with a balanced fertilizer or one with low phosphorous.
12-12-12 or 8-5-5.
Lift the plants to apply the fertilizer to the soil and not the plants themselves.

Q. Pachysandra

I have an area about 2′ X 40′ that gets maybe 2 hours of midday sun each day. The ground is clay.

1. Do you think Pachysandra will thrive in this area as a ground cover?
2. What would I need to do prepare the ground besides running a rototiller through it?

Thanks for your help,
Ralph Mayer

Amending the clay soil is an option and good idea to optimize the plants you can grow and the success of what you do grow.
Some options for your area may include Creeping Jenny, Snow on the Mountain, Canada Violet, Beacon Silver.
Pachysandra plantings would thrive in a more loamy, well draining soil.
