Helenium Care Guide

To ensure your Helenium plants thrive, it’s essential to provide them with the right growing conditions and care. Here are some key care requirements for cultivating healthy Helenium plants:

Helenium plants can tolerate humidity and hot summers. Proper spacing is essential to prevent fungal diseases in high humidity.

Fertilizer

Helenium plants are not heavy feeders. Apply a balanced flower fertilizer in the spring, following the product label instructions.
