Oops... maybe too much roundup help!!!!

13 years ago

I'm a bit of a newbie with the gardening stuff so this is definitely my fault. Did a bunch of landscaping last year and got rid of some snow on the mountain to make way for some nice mulch and maybe some decorative grasses. Tried digging it up at first (not fun) and at the suggestion of the landscaper I later used round up to knock it out.

There is a clematis on a trellis in the same area. I protected it from overspray using a piece of cardboard, but I believe the Round-up got into the soil. Late last summer the clematis suddenly withered badly. But it came back strong this spring with a new shoot and has been filling out nicely. Last week though, it suddenly turned yellow and appears to have halted growth. I'm thinking i ruined the soil and will have to replace it(the soil), but don't want to lose the clematis.

Any suggestions?

Thanks!

Forgot to mention, I have yet to replant anything else in the area, so there are no other signs of poor growth.

You are mistaken about the Round Up. It does not harm soil. It certainly would not cause any harm a year later. Round Up has to be taken in by the plants foliage to do harm.

What you are describing is typical Type II large flowered hybrid Clematis growth or lack there of.

Cut back anything that looks bad and keep it fertilized (gently with organics) and watered. If you planted it deeper when you planted it that will help it outgrow this problem.

If it grows one long scraggly vine keep pinching it back to promote more.

That's good news- I'm happen to be mistaken in this this particular case. You are are right on with "one scraggly vine" thing- i've had to train it a little to keep it full. Looks like it just needs some TLC. Thanks!
