French marigold 'Hero'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Hero is thought of as half hardy, so although it can survive a small mild cold snap, it is wise to ensure that this plant is protected from frost damage.

Sow the seed thinly in pots or trays on a windowsill or in a greenhouse in a good quality, finely sieved, moist compost.

Sow 0.23 inches (0.6 cm) deep with a guideline distance of 1.95 inches (5.0 cm). Soil temperature should be kept higher than 15°C / 59°F to ensure good germination.

By our calculations, you should look at sowing Hero about 49 days before your last frost date.

Transplant seedlings spacing them 5cm apart in trays and grow on. Acclimatise the plants to outside conditions and then plant 15 – 23cm apart in a sunny place.

As Hero is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
