Sowing Guide

Early Sowing/Module Sowing

Sow seeds on the surface of moist compost in trays, modules or pots.
Lightly cover the seeds with vermiculite or compost.
Place in a propagator or a clear polythene bag and seal. Germinate in a dark location at the temperature suggested above.
Once germination has started remove from the bag or propagator and position in a well lit area with a reduced temperature. Protect from direct exposure to hot sun and frost.
When large enough to handle transplant into 7.5 cm pots.
Grow on in a greenhouse or cold frame. Protect from frost.
Plant out when all risk of frost has passed and the plants are growing strong.
Harden off the phlox plants over 7 - 10 days before planting out to reduce shock.

Direct Sowing

Thinly sow the seeds in April - May in well prepared seeds beds were the plants are to flower in rows 30 cm apart at the depth suggested above. The soil should be a fine tilth.
Water well.
When large enough to handle thin to 15 - 25 cm apart.

Growing On

Water the young plants well until established.
To encourage a bushy habit, pinch out the growing points when the plants are 8 - 10 cm tall.
The plants will benefit from having a general purpose fertilizer adding every 4 - 5 weeks.
Water established plants well in dry conditions. Avoid overwatering.


Dead-head spent flowers regularly to prolong the flowering season.
