Growing Zone Information

  zone map key code

This USDA map divides the country into PLANT HARDINESS ZONES based on average lowest winter temperatures (see map below). We include ZONE ranges in our descriptions of hardy plants so you can tell if the plants you choose can survive in your location or the location of a gift recipient. We ship live plants, roots and bulbs at the right time for planting for your zone.

For annuals we list your expected Spring frost free date - this is helpful in determining when you can safely plant annual seeds and plants.

Your Zone Zone 10 Zone 9 Zone 8 Zone 7 Zone 6 Zone 5 Zone 4 Zone 3

Gardening Tip of the Day

  • Don’t ignore garden debris that can harbor insects and diseases to attack next year’s garden. Collect leaves, sticks and plant stems and run them through a shredder before adding to the compost pile. If the pile heats up well (to about 170 degrees), most insects, weed seed and diseases should be destroyed. If you don't compost, use the debris as mulch on unrelated plants. For example, don't put tomato debris where tomatoes, peppers, eggplant or potatoes will be planted next spring. For that matter, use all vegetable waste to mulch bushes, trees and perennials. Simply rake plant debris into rows and run a mulching lawn mower over it several times before spreading.
