I have 2/3 acre lawn which I can’t water. So I need to time application of crab grass preventer when it will rain after my application. Also you advise time is right between forsythia blossoms falling off & lilacs blooming. However it may not be raining right at that time. Is it ok to apply it today, April 14th ? as it will be raining next 2 days.
Thank you very much for any info.
