Light

Water
The little sunflower flourishes in consistently moist soil, benefiting from weekly watering that mirrors the regular rainfall of its native environment. Although it is usually grown outdoors, this plant adapts well to seasonal changes between wet and dry conditions. This resilience makes it an excellent choice for gardens with varying moisture levels.
Fertilizer
The best time to fertilize a Little sunflower is in early spring, as it comes out of dormancy and begins active growth. Fertilizing supplies essential nutrients for healthy development. Although Little sunflower has relatively low fertilizer needs, yearly fertilization can improve its survival and encourage better, longer-lasting flowers.
