Gaillardia, also known as blanket flower, is a vibrant perennial that adds color and texture to gardens. Proper fertilization is essential for healthy growth and abundant blooms. Understanding the right schedule and amount of fertilizer can help gardeners achieve the best results.
Understanding Gaillardia’s Nutritional Needs
Gaillardia thrives in well-drained soil and prefers a balanced supply of nutrients. While it is relatively low-maintenance, providing the right fertilization can enhance its flowering and overall vigor. Over-fertilizing, especially with high nitrogen, can lead to lush foliage at the expense of blooms.
When to Fertilize Gaillardia
The optimal time to fertilize Gaillardia is during its active growing season, typically in early spring and mid-summer. Avoid fertilizing late in the season, as this can promote unwanted foliage growth and reduce flowering. If you notice your plant is not blooming well, a light feeding in early fall can sometimes help.
Spring Fertilization
Apply a balanced, slow-release fertilizer when new growth begins. This provides essential nutrients for strong development and prepares the plant for a productive season.
Mid-Summer Boost
A second, light feeding in mid-summer can promote additional blooms. Use a water-soluble fertilizer diluted to half strength to avoid overfeeding.
How Much Fertilizer to Use
Gaillardia does not require heavy fertilization. Generally, a tablespoon of balanced fertilizer per square foot, applied during the recommended times, is sufficient. Always follow the manufacturer’s instructions for specific products.
Over-fertilizing can lead to excessive foliage growth, weak stems, and fewer flowers. It is better to under-fertilize slightly than to overdo it.
Additional Tips for Fertilizing Gaillardia
- Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium (e.g., 10-10-10).
- Apply fertilizer around the base of the plant, avoiding direct contact with foliage.
- Water thoroughly after fertilizing to help nutrients penetrate the soil.
- Mulching can help retain soil moisture and provide additional nutrients as it decomposes.
By following a proper fertilization schedule and using the right amount of nutrients, gardeners can enjoy healthy Gaillardia plants with vibrant, long-lasting blooms throughout the growing season.
