Phlox growing guide

Phlox

Botanical Name: Phlox paniculata
Family: Polemoniaceae
Plant Type: Herbaceous perennial
Size (HxW): 60-90cm x 30-60cm
Depth & Spacing: Plant where the roots meet the stem with the roots spread evenly below the soil surface. Space 30-60cm apart.
Soil: Humus rich, moist, well drained soil is ideal. Improve soil conditions by adding organic matter and compost prior to or at the time of planting.
Aspect: Full sun to semi shade, shelter from the hot afternoon sun.
Climate: Cool to Mediterranean
Frost: Hardy
Water: Water to establish, it takes 4-6wks for the roots to penetrate the surrounding soil and establish, then keep moist in active growth. Ideally, water the ground, not the foliage.
Fertiliser: For best flowers it is a good idea to add some fertiliser as they are gross feeders. Fertilise when the foliage appears in spring and again when they start to flower in summer.
Flowering Time: Summer to autumn
After Flower Care: To prolong the flowering, dead head spent blooms as you go. Or, after the first flush, remove the stems to about a quarter, add some fertiliser and water it in, you will have another bloom season in no time.
Notes: This plant is great as a cut flower and an excellent addition to a cottage garden. Mulch in spring to help with water retention. If powdery mildew occurs, cut the foliage off and dispose of it then add some fertiliser, they have a strong natural resistance and, unlike other Phlox, even if they are affected by mildew, they will still flower. Dig and divide every three or four years to keep them vital.
