How long is the common practice for including a guarantee for installed plants?

The common practice for including a guarantee for installed plants is typically 90 days. This time frame is considered a reasonable period for clients to observe how well the plants have established themselves in their new environment. During this period, any potential issues related to the health of the plants, such as shock from transplantation or initial failures, can often be identified and addressed. A 90-day guarantee strikes a balance, allowing enough time for the plants to acclimate while also being a manageable commitment for the installer. This duration is commonly accepted across the landscape horticulture industry to ensure customer satisfaction and confidence in the quality of the work being provided.
