In the prior 24 hours, we received almost 1" of much needed rain. You might ask why we are watering on days it rains. Today was a scheduled "wetting agent" application and these types of products must be irrigated after application. So rain or shine, we water for a few minutes after spraying.
Wetting agents are surfactants.Surfactants modify the surface tension between water and soils or plant surfaces, making it easier for water to infiltrate and moisten the underlying soils. They make water more effective.
