Hellebore From Seedling to Thriving Perennial

Hellebores are a marvel, offering stunning spring blooms and year-round evergreen foliage. However, getting young plants to flourish can be a challenge. The good news is, with the right care, these "temperamental" newbies become hardy, low-maintenance perennials for years to come. Here are key tips we pass on to our garden centers, wholesale growers, landscapers, municipalities, and other plant retailers to ensure their success stepping up Hellebores plugs to larger containers:

Nurturing First Impressions:

The first year is crucial for a hellebore's development. Some yellowing (chlorosis) in the foliage is common, but do not panic! Here is how to combat it:

• Iron Power: Additional iron sprays every 2-3 weeks, followed by another 2-3 weeks for results, can significantly improve color.
• Targeted Drenches: Drenches with higher PPM nitrogen and iron provide a much-needed boost.
• Patience is Key: Remember, the second season sees far less chlorosis.

Water Wisdom:

Water quality significantly impacts plant growth. Here is what to consider:

• Mineral Magic: Hellebores thrive with specific calcium and magnesium levels. Test your water and adjust fertilizers accordingly to achieve the ideal range for these elements.

Feeding for Success:

Hellebores have distinct feeding needs throughout the year:

• Spring Feast: When emerging (late winter/early spring), they require frequent feeding (around 200 ppm nitrogen every 2-3 weeks) or continuous low-dose nitrogen injection.
• Summer Slumber: During summer, ease off or completely stop fertilizing as their growth slows.

Ideal Environment:

• pH Preference: A slightly acidic environment (pH around 5.8-6.2) is ideal.
• Moisture Management: Aim for a pour-through EC of 1.5-2.0. While they prefer moist soil, avoid overwatering to prevent diseases like Botrytis, crown rot, and root rot.
• Spacing Matters: Good air circulation is key. Ensure proper spacing between plants to keep humidity low and prevent disease.

By following these tips, you will transform your hellebores into thriving perennials that will grace your garden for years to come.
