Disappointed & angry. After spending thousands of dollars, all of the plantings in our rock garden died. Every single one! Perhaps that's why they only guarantee them for 3 months. Paid top dollar to ensure we'd have NO grass/weeds in our beds, but we still do! They told us we could pay for more "treatments" to keep them out, which was supposed to be included (it's in the contract, but carefully worded so it can be misinterpreted). So we paid around $8000, and we have approximately 15 - 20 shrub-type plantings along our house that are alive, which comes to at least $400 per shrub!!!
