Yellowing leaves on clematis

Post by OnyxsLawn » Fri Jun 14, 2019 4:37 pm

I’ve got some issues with the clematis I planted this spring. It’s gotten insecticide fungicide and miracle grow bloom booster over the last month and is still getting worse. Any ideas?

I can't see the leaves very well, but it could be chlorosis (aka iron deficiency). A good sign is yellowing leaves, with darker veins. It could be either a lack of iron in the soil, or an inability for the plant to use the iron due to the soil being too alkaline. A few products I have used to counter it are espoma soil acidifier and iron-tone. Also I have used the fertilome liquid iron for a foliar feed.

A few other things that it is tough to judge from the photo. I have always heard clematis like to grow toward sun, but have shade at their roots. So maybe its getting a little too much sun at its feet? They also like well drained soil. So it could possibly be a little soggy there?

thanks! I'm gonna try some iron and see if that helps. The soil is well drained but its just been raining constantly. I think that may have something to do with the iron deficiency too.

Would more mulch around the base help to keep the roots cooler?

Some people will plant something in front of the clematis, on ours we plant a potato vine to keep the roots cool.

Yea. My parents always put some mounding annuals at the base to eat up some of the sunlight. SPV, petunias, etc.

Put a couple of handfuls of compost at the base of each to help with the nutrients and yes plant something at their base. I have creeping phlox under mine and together they are beautiful in mid spring.

Thanks for all the help! I added some Iron sulfate and magnesium sulfate to my watering yesterday and some peat around the roots. I'm also going to plant some phlox I got from my mom around the base to shade them some.

Good plan! Here’s mine taken their third year after planting. The phlox bloom early spring and the clematis pop about 3 weeks behind.
