USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Planting and Caring for Pre-Planned Gardens & Collections

Soil Preparation: Remember that proper soil preparation is the key to healthy, vigorous blooming perennials. Use Yum Yum Mix and a high quality compost at recommended rates to prepare the soil. Inoculate the plant roots with Plant Success mycorrhizal inoculant. Planting: Plant according to the mature size of the plant. Don’t be tempted to put the plants too close based on their size in the pots. They’ll need the space to grow and fill in the expected area.

Fertilizing: Once annually in mid-fall, after plants begin to go dormant. Use Yum Yum Mix or Yum Yum Mix Winterizer at recommended rates to improve the soil and provide essential plant nutrients.Use it with high quality compost, mix half and half by volume and spread on top of the soil. Scratch it in lightly and water thoroughly. It is also beneficial to treat the plant roots with Plant Success® mycorrhizal root inoculant if you didn’t do so at planting time. (Inoculation only needs to be done once.)

Mulching: In arid climates mulching is very beneficial. Coarse textured composts, shredded leaves, pine needles and composted bark are all excellent mulch materials. Apply to a depth of 1-2 inches. Replenish annually (or as needed).
