When to plant Garden phlox 'Bright Eyes'?

Phlox paniculata 'Bright Eyes' thrives in full sun or partial shade, though flowering is most prolific with at least six hours of direct sunlight daily. Choose a spot with good air circulation to reduce disease risk. This cultivar tolerates loam and clay soils but demands good drainage; waterlogged roots in winter can be fatal. Before planting, dig in plenty of well-rotted compost or manure to improve soil structure and moisture retention, especially important on clay. Plant container-grown phlox in March, April, May, September, or October. Autumn planting allows roots to establish before winter, but spring planting works well if you keep new plants watered through their first summer. Dig a hole slightly larger than the root ball, set the crown at soil level—never deeper—and backfill, firming gently. Space plants 45 cm apart to allow air to circulate freely between mature clumps, which helps prevent powdery mildew. Water thoroughly immediately after planting to settle soil around the roots and eliminate air pockets. Apply a 5 cm layer of organic mulch such as garden compost or bark chips around the base, keeping it a few centimetres clear of the stems to avoid rot. If planting in spring, water regularly for the first eight to ten weeks until the root system is established. Autumn-planted phlox usually needs less attention, relying on seasonal rainfall, but check during dry spells in late autumn. Staking is rarely necessary if plants receive enough light and are not overcrowded, though tall stems on exposed sites may benefit from discreet support with twiggy pea sticks inserted in mid-spring.
