What is the sunlight requirement for Hairy Sunflower

Hairy Sunflower requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Bristly Sunflower is always in the right place to thrive.

What's the right humidity for Hairy Sunflower

The Hairy Sunflower does not need extra humidity. Plants primarily absorb water through their root system, making soil watering the best way to provide humidity to your plants.

How to fertilize Hairy Sunflower

The Hairy Sunflower should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.
