Sow at a depth of approx.
0.25 inches (0.64 cm) and aim for a distance of at least
0.98 inches (2.5 cm) between Sweet pepper plants. Soil temperature should be kept higher than
20°C / 68°F to ensure good germination.
By our calculations, you should look at sowing Sweet Banana about 32 days before your last frost date.
As Sweet Banana is tender, ensure temperatures are mild enough to plant out (around 10°C / 50°F as a guideline) - wait until after your last frost date to be on the safe side.
