Tickseed 'Tetra Riesen'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Tetra Riesen is thought of as hardy, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea). A soil ph of between 6.1 and 7.8 is ideal for Tetra Riesen as it does best in weakly acidic soil - weakly alkaline soil.

Aim to sow 0.0 inches (0.0 cm) deep and try to ensure a gap of at least 11.7 inches (30.0 cm). Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

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

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