The Basics of Fertilizing Hydrangeas

Hydrangeas are a popular flowering shrub known for their large, showy blooms. However, in order to achieve those beautiful blooms, it's important to properly fertilize your hydrangeas. In this article, we'll go over everything you need to know about fertilizing hydrangeas in the spring.

Why Fertilize Your Hydrangeas?

Fertilizing your hydrangeas is crucial to ensuring they receive the proper nutrients needed to grow and thrive. When you provide your hydrangeas with the right balance of nutrients, they will produce more vibrant blooms and healthier foliage.

When to Fertilize Hydrangeas

The best time to fertilize your hydrangeas is in the spring, just before new growth begins. This allows the plant to absorb the nutrients needed for healthy growth throughout the growing season. Avoid fertilizing too late in the season, as this can lead to tender new growth that will be damaged by an early frost.

Choosing the Right Fertilizer for Your Hydrangeas

Understanding N-P-K Ratio

When choosing a fertilizer for your hydrangeas, it's important to understand the N-P-K ratio. This ratio represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. Different types of plants require different ratios of these nutrients, so it's important to choose a fertilizer specifically formulated for hydrangeas.

Organic vs. Synthetic Fertilizers

There are two main types of fertilizers: organic and synthetic. Organic fertilizers are made from natural materials, such as bone meal or compost, while synthetic fertilizers are made from chemicals. Both types can be effective for hydrangeas, but many gardeners prefer organic fertilizers as they are more environmentally friendly.

How to Apply Fertilizer to Your Hydrangeas

Measuring Your Fertilizer

Before applying fertilizer to your hydrangeas, it's important to measure the correct amount. Follow the instructions on the fertilizer packaging to determine how much to use based on the size of your plant.

Applying Fertilizer

Once you've measured the correct amount of fertilizer, sprinkle it evenly around the base of your plant. Be sure to avoid getting the fertilizer on the leaves, as this can cause burning.

Watering Your Hydrangeas

After you've applied the fertilizer, give your hydrangeas a thorough watering to help distribute the nutrients throughout the soil.

Troubleshooting Common Fertilizing Problems

Burned Leaves

If you notice your hydrangea leaves turning brown and crispy at the edges, this may be a sign of fertilizer burn. To prevent this, make sure to apply fertilizer evenly and avoid getting it on the leaves.

No Blooms

If your hydrangeas aren't blooming, it may be a sign that they're not receiving enough nutrients. Try applying a balanced fertilizer to help promote healthy growth and blooms.
