Common zinnia 'Red-blue spectrum'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Red-blue spectrum is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Ensure your soil is loamy and sandy and has a ph of between 5.5 and 7.0 as Common zinnia is a weakly acidic soil to neutral soil loving plant.

Try to aim for a seed spacing of at least 11.7 inches (30.0 cm) and sow at a depth of around 0.25 inches (0.64 cm).

By our calculations, you should look at sowing Red-blue spectrum about 21 days before your last frost date.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Red-blue spectrum is a tender plant.
