PlotStartis a spray that provides instantly available calcium to the soil and plants. Historically, lime has been the source of calcium. However, with traditional lime taking months to activate and liquid lime only lasting a single season,PlotStartbegins working the moment it touches the ground and provides available calcium for years to come. The 1 gallon ofPlotStartwill cover up to one-half (1/2) acre. PlotStart can be applied at or before planting to both tilled and untilled ground. It also can be applied to perennial plots, trees, and shrubs to give the soil and plants a needed boost.
