Care
SunFill™ Purple Sunflower Care
Plant in full sun after the danger of frost has passed. Direct-sow seeds or transplant young plants into well-drained soil with moderate fertility. Avoid excessive nitrogen, which can produce tall plants with weaker stems.
Water regularly during establishment and in prolonged dry spells, but allow the soil surface to dry between waterings. Support taller stems if grown in windy areas. Deadhead or harvest mature heads to encourage continued production.
For best performance, feed with a balanced slow release fertilizer early in the growing season.
