Calendula 'Porcupine'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Porcupine is thought of as half hardy, so remember to protect this plant from frosts and low temperatures. Ideally plant in loamy soil and try to keep the ph of your soil between the range of 6.1 and 7.8 as Porcupine likes to be in weakly acidic soil to weakly alkaline soil.

Try to aim for a seed spacing of at least 7.8 inches (20.0 cm) and sow at a depth of around 0.39 inches (1.0 cm). Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.

By our calculations, you should look at sowing Porcupine about 35 days before your last frost date.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Porcupine is a half hardy plant.
