Phlox are generally sun-loving native plants that attract butterflies. Many phlox varieties are wonderfully fragrant. Phlox can be divided into two groups;
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.
- 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.
- 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.
- These are low-care perennials that need little attention once established.
- 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.

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).
