Celosia Yellow plants like full sun and they perform their best when grown in rich soil with lots of organic matter added to the soil. The soil needs to be moist but not saturated. Water Plume Plant regularly during dry periods. Celosia benefits from applications of a general-purpose fertilizer once or twice a month.
Celosia Yellow Plant seeds are very tiny. For areas with a long growing season, Celosia flower seed can be directly sown into your flower garden in prepared soil after the frost season has passed.
For cooler areas with shorter growing seasons, start the Wool flower seeds 4- 6 weeks before the last expected frost. Press the Celosia seeds into the soil but do not cover them. The flower seeds need to stay moist and require warm soil to germinate. Pinch back the early blooms to encourage more branching.
