Harper’s Nursery offers a lifetime guarantee on all plant material one gallon or larger that is a perennial or woody ornamental. Annuals, vegetables and soft color are not included. To receive the guarantee, the appropriate amounts of Start-N-Grow and mulch must be purchased on the same receipt as well as following the planting instructions on our free planting guide. To obtain a replacement plant, the original sales receipt and the dead plant must be returned to the nursery. In-store credit or a new plant will be given as replacement. We do not give refunds for plants that perish that were on lifetime guarantee. To continue the lifetime guarantee, new Start-N-Grow and mulch must be purchased. Plants purchased without any amendments have a 30-day guarantee. Labor charges are not included in this guarantee. Guarantee does not cover acts of God (freeze, hail, etc.) or improper maintenance.
