Start off about 7 or 8 weeks before you expect the last frost of winter / spring. The Mexican sunflower seeds should be sown on the soil surface, and will take from half to two weeks to germinate at a temperature of about 20 degrees centigrade. The young seedlings of Mexican sunflowers should be transplanted outdoors following the last frost of spring at a spacing of around 60cm apart. Tithonia species should be grown in sunny areas of the garden and like a light soil. Caring: It is quite easy to care for Mexican Sunflowers and other Tithonia. They are quite tall so provide them with a stake, they like hot dry areas, so only provide with water during drought. As Mexican sunflowers are annuals they should be grown from seed, so don't take cuttings or divide the plants for purposes of propagation.
