Help our phlox is dying...it started turning brown at the base and worked its way up. The stems are growing very tall as well.
Phlox can suffer from several diseases from root rot to powdery mildew. Heavy soils, planting too close together or overwatering can all lead to problems. Tall thin plants can also be due to lack of sunlight. Take a sample of your phlox with some pictures in to your local county extension office. If they cannot diagnose the issue they can send it to the disease diagnostic lab.
