Threadleaf coreopsis 'Zagreb'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Zagreb is thought of as hardy, so this plant will survive close to or on freezing temperatures. A soil ph of between 6.1 and 7.8 is ideal for Zagreb as it does best in weakly acidic soil - weakly alkaline soil.

Try to aim for a seed spacing of at least 11.7 inches (30.0 cm) and sow at a depth of around 0.0 inches (0.0 cm). Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

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

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