When looking at the details of our products some of the items will have a Care Level. This is an indicator of the difficulty that a gardener might have when growing and caring for that particular item. Here is a description of what each Care Level mean:

1 = Easy - these items are the easiest crops to grow. They are typically quick to mature and need little care.

2 = Moderately Easy - these items are generally easy, but a bit more demanding than 1s or have a longer time to maturity.

3 = Normal - these items include the bulk of items transplanted to the garden as bulbs, dormant bare root, or potted plants.

4 = Somewhat Difficult - these plants have certain needs or requirements that must be met to succeed with them. These may include specific soil requirements, regular pruning at the proper time of year, or preventative spraying for pest and disease control.

5 = Difficult - Category 5 items are challenging to grow, and are best suited to experienced gardeners. They have specific site requirements or environmental needs that must be met in order for them to grow well.

A: What is McClure & Zimmerman's Company's refund policy? Back To Top

We guarantee your bulbs will arrive in excellent condition and will be true to name. If you have any doubts about quality when your bulbs arrive, tell us promptly. We'll replace the unsatisfactory material or refund the full price and shipping, whichever you prefer. We reserve the right to request return of the merchandise to receive adjustments.

If any plant material fails during the growing season and we are notified within one year from date of shipment, we will replace it one time or issue a credit toward future orders provided the stock has been planted according to instructions and in growing zones recommended in our catalog. We do not guarantee against losses due to weather, animals or other factors beyond our control.

McClure & Zimmerman pledge has been to provide quality products at a fair price. That pledge has not changed. Please check your order immediately upon arrival and report any problems promptly. We reserve the right to request return of any product deemed unsatisfactory prior to approval of any adjustment.

Any plant materials purchased in the spring which fail to grow will be REPLACED or CREDIT VOUCHER ISSUED, one time, provided they have been properly cared for and we are notified by October 1st of the year purchased.

Bulbs or plants shipped in the summer or fall which fail to grow will be REPLACED or CREDIT VOUCHER ISSUED, one time, provided they have been planted properly and the loss is not due to poor winter protection or rodents and we are notified by June 1st of the following year.

We guarantee your complete satisfaction with our gardening supplies and accessories (non-growing items) when used according to manufacturer's instructions.

Our liability is limited to the purchase price of the item being replaced.

NOTE: Seeds are living products that depend on many factors such as proper planting time and technique, depth of sowing, soil, proper germination environment, fertility, disease control, insect control, and reasonable weather for direct sown seeds. If any of these factors are not right, it may cause the seed to not perform and because most, if not all, of these are out of our control, most of the success of these seeds is in the hands of the grower. If they have been cared for properly and still fail to grow, we will REPLACE the seed or ISSUE A CREDIT VOUCHER, one time. We guarantee that the seeds we sell conform to the label; however, our liability is limited to the purchase price of the seed.

Sale items will only be issued a credit voucher for the purchase price.
