No liquid fertilizers from a low volume boomless sprayer, which is what a PG is. The mix is way too hot. Especially on lawns where there is no irrigation. I can put down mixes that have 3/4-1 lb of N in 2 gallons per 1000, but that is followed by my switching on irrigation before I drive away. On big lawns, I am spraying ahead of each irrigation zone. Even the expensive golf green foliars such as Griggs or SeaQuential, require at least 2 gallons per 1000.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
