Will Celsius harm other plants like forsythia, azaleas, bulbs and/or trees?
Some ornamentals may be sensitive to Celsius and since it wasn't tested for use on ornamentals it is best to try and avoid spraying them with Celsius. Do not plant ornamentals or bedding plants in treated bare areas for at least 30 days after the last application of this product.
