I am in South Texas and wanting to know when the best time is to apply. Does the daily low temperature need to be up to a certain temperature?

When using Ortho Weed B Gon Weed Killer For St Augustine Lawns temperatures must be consistently between 65-90 degrees and nighttime temperatures should not be below 55 degrees. If day or nighttime temperatures are lower we recommend waiting until temperatures are more consistent, so that results are better.
