What temperature should be good to apply potassium? Is it rainfast? Do I need to water after applying? How long apart the I can apply second time when my potassium in my lawn is low?
You can apply the 0-0-25 Liquid Potassium Solution when temperatures at the time of application are under 85 degrees. This does not mean that the temperatures cannot exceed that during the day, only that at the time of application they should be under this range, ideally in late evening just before sun down. We recommend applying when rain is not expected within 6 hours at minimum, but ideally 24 hours after an application to allow for adequate time to be absorbed into the plant and soil. As long as you use adequate water volume during application you would not need to water in after applying to the lawn. The manufacturer recommends applying every 7-21 days as your lawn needs throughout the season.
