CW – I heard that! They said that bark can contain horsetail rhizomes, right?

Bark and soil wash away, gravel less so.

Bark – many kinds if not all – is an allergy trigger and tends to contain weed seeds and runners. NPR or KUOW last weekend had a great gardening segment about invasive plants and weeds that covered some of this.

Does anyone know why they are putting gravel around the trees instead of bark or soil?
