Farming method

'Oklahoma' zinnias can be sown indoors or directly in the garden. For indoor sowing, start 4 to 5 weeks before the last frost in a light, well-draining potting mix, maintaining a temperature of 20 to 22°C (68 to 72°F); germination usually occurs in 7 to 10 days. Transplant seedlings carefully, as zinnias do not tolerate late transplanting. For direct sowing, sow outdoors towards the end of May, once all risk of frost has passed. This variety prefers full sun but tolerates light shade and requires rich, well-drained soil amended with organic matter.

Growing tips

When transplanting, work the soil to a depth of about 30 cm and incorporate compost to encourage rapid growth. Good air circulation is essential to limit the development of foliar diseases, particularly powdery mildew. Regularly pinching back the plants stimulates branching and significantly increases the number of flowers produced. Regular, but not excessive, watering promotes abundant and continuous flowering.

Harvest

Harvest the flowers when they are fully open to fully enjoy their colors and vase life. Prolific, robust, and versatile , the 'Oklahoma' zinnia mix is ​​an excellent choice for gardeners wishing to combine cut flower production and garden beauty with minimal maintenance and maximum visual impact.
