Knowing specifically why a plant dies is an inexact science. Research which diseases a plant is prone to and the list is varied and long. So many factors contribute to the decline and death of a plant, it can be impossible to pinpoint the cause.
A disease or a pest could have attacked the plant in the nursery where it was grown, during shipment or on the lot at the retail center. Plus, a disease may manifest in a plant but not kill the specimen until some time later.
Of course water — too much or too little — always contributes to a plant’s healthiness. A plant needs strength to resist a predator, be it a pest, fungus or bacteria. If its’ resistance is low due to drought or lack of watering, it becomes more susceptible to these detriments.
Sullivan’s Landscaping makes every attempt to work with its customers but cannot be responsible for plants a customer does NOT water. As well, SLI cannot be responsible for a disease which manifests after a plant is installed. I, like any contractor cannot control drought, pest colonies or microclimate diseases that attack plants. To that end, SLI will not pay for the replacement of a plant it installs after 30 days.
After that, SLI will gladly replace the plant free of labor and delivery charges but will charge the customer for a replacement plant, be it the same genus or one of similar habit and cost.
Please follow the watering instructions I provide for each plant. Remember, all plants have different water needs. Some are more drought-tolerant than others. Some are better at tolerating damp conditions or “wet feet” than others. Plus, where your garden is situated — heavy shade, full sun, partial shade, dappled sunlight, marine clay, rocky soil, soil rich in humus or even slope of the land — has everything to do with how much water your plants will need.
