Will Creeping Myrtle Smother Vanhouttie Spirea?

Question

I have a beautiful row of White Vanhouttei Spirea, and would like to plant Creeping Myrtle under it, as ground cover, but not if the Creeping Myrtle will cause a problem for the Vanhouttei Spirea, as it did smother my Flax. Thank you very much, Jean

Answer 1

I think that your Spirea will be large enough to be unaffected by the Vinca. Just keep an eye on moisture, and nutrient levels in the soil. These articles will help:
