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.

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.
