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 Guides
Phlox (tall and groundcover types)
Phlox are generally sun-loving native plants that attract butterflies. Many phlox varieties are wonderfully fragrant.

Phlox can be divided into two groups;
  • Phlox paniculata (Tall garden phlox)
  • Groundcover types (Phlox nana, P. kelseyi, P. subulata and others)
  • Phlox paniculata (Tall Garden Phlox) - tall, showy perennials blooming in mid-summer with fragrant flowers.
    • Preferred growing conditions:
    • Grows best in compost enriched garden loam. Avoid heavy, wet soils and clay.
    • Likes to be mulched to keep soil more evenly moist. Most common mulching materials are fine.
    • Likes to grow in soil that stays evenly moist.
    • Plant in full sun
    • Enrich the soil at planting time with good quality compost and Yum Yum Mix.
      • Special comments:
      • Phlox can sometimes be troubled by powdery mildew, but planting mildew-resistant varieties, keeping the soil evenly moist and not watering overhead in the afternoon/evening will prevent most outbreaks.
      • Deadhead to prolong blooming.
      • These perennials appreciate yearly fall applications of Yum Yum Mix and compost to improve the humus content and enhance water-holding capacity of the soil.
        • 2. Phlox nana, P. kelseyi, P. subulata and others (Groundcover Phlox)
          These perennial species are low growing and are used as groundcovers. Some are evergreen and most have fragrant flowers.

          Preferred growing conditions:
        • These species grow in a wide range of soil types including clay.
        • Most of these groundcover varieties prefer coarse-textured mulches like pine needles, crushed nut shells and crushed gravel.
        • Many of the groundcover phlox are xeric and only need periodic deep watering during summer heat.
        • Plant in hot, full sun areas.
        • They only need modest soil improvement, so use a few handfuls of Yum Yum Mix and good quality compost to prepare the soil for planting.
          • Special comments:
          • These are low-care perennials that need little attention once established.
            • Garden care:
            • Cut back herbaceous species like Phlox nana in mid-spring. Evergreen types like P. subulata and P. kelseyi need no trimming or cutting back.
            • Fertilize once in the fall with Yum Yum Mix and Planters II.
