Grow Godetia in full sun. These plants need lots of sun, or they will grow slowly. They grow well in average to rich soil. Mix in compost when planting. Keep the soil moist, but not too wet. Add a general purpose fertilizer when planting them, then once a month after that.
Godetia are easy to grow. As wildflowers, they require little care. In the home garden, mulch around them to help retain soil moisture, and to keep the weeds down. The flowers bloom early to mid summer. Taller varieties may require staking.
