Answer for will rain effect plotboost once it is sprayed on.what kind of weather is best for applying

PlotBoost is most effective with a 1 hour rain fast drying period. Although rain will just wash it into the soil and the product is also soil active, the most impressive results will be for intake by the plant directly as sprayed on the foliage. This drying period is similar to most herbicides. Also it is most effective when sprayed in temperatures less than 85-degrees and when plants are wet (pores in leaves are open). this could be after a recent rainfall or early morning dew. If the plant is not wet the product is still very well absorbed into the plant, but the above recommendations are if you want the perfect scenario.
