Free(ish) Plants: Garden Center Clearance Racks
Most chain and big-box garden centers have a clearance rack for scorched and dying plants. These almost-dead plants are usually 50% or more off the original price.
I didn’t have too much luck buying these plants. Of the 12 plants I bought off the Lowe’s clearance rack for $10, only 3 survived – 25% survival rate. I had much better success with the free plants – 97% survival rate.
