Balsams prefer a moisture retentive well-drained soil in either full sun or partial shade.

Apply a balanced liquid feed weekly from May to September.


Week 14:

Sow seeds in pots/trays of seed compost, and germinate at a temperature of 18°C (65°F)

Germination should take about 5-7 days.

Week 15- 16:

Prick out the seedlings, when large enough to handle, into cell trays or 50mm (2") pots of potting compost.

Later pot on into 75mm (3") pots, and gradually harden them off in a frost free cold frame until planting out or potting up time.

Week 22:

Plant out in borders 400-500mm (15"-18") apart in fertile well-drained soil, in full sun or partial shade.

Once growth is established pinch out the growing tip to encourage bushier plants.

Those to be grown in pots should be transplanted into suitable sized pots of Ji2 potting compost (or equivalent) then placed in a sunny sheltered spot.
