I purchased a healthy mint plant, brought it home and it is growing fine. Now all of the sudden the leaves in the center of the plant are dying and spreading to the whole plant. Kind of like someone sprayed weed killer on it. Any ideas? Thank you

When watering be careful to not to water down into the crown of the plant. This can cause root rot.
Water along the edge of the pot or even set the pot in a water tray until it has drawn up the water.
Make sure the soil is draining and not holding moisture.
