20-20-20 may be applied as a spray past the point of runoff(10-20 gallons) per 1000 and 2 lb per 100 gallons as often as every 7 days. I make an application like this to most ornamental areas every 30 days(palms, perennials, woody shrubs). Annuals and herbaceous plants do like their fertilizer.
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.
