Two summers ago, the Plant Clinic policy changed to require receipt of payment with the sample. Part of the motivation for this change was the great amount of time staff was spending on bills, rebills, and pro-cessing of money. We do not have a separate billing office, and we would have to double our fees if we used one. A decision was made to require payment up front and preferably payment by check. Most clients have complied with few complaints. This notice is to remind everyone of this policy and to state that starting June 19 there will no longer be any exceptions to the rule. Payment must accompany the sample or the sample cannot be processed. Please help us help you.
