What to Feed Hydrangeas for Bright, Beautiful Blooms
What to Feed Hydrangeas?
To feed hydrangeas, a good all-purpose 12-4-8 or 10-10-10 fertilizer composition will provide the necessary nutrients.
Slow-release fertilizers formulated for shrubs and trees are recommended, but fast-release compounds can also be used.
Alternatively, a combination of sulfur, compost, and peat moss can be used as a natural fertilizer.
Fertilizing should be done lightly to avoid burn, and can be done in March, May, and July around the drip line of the branches.
Liquid iron can be applied bi-annually to keep the leaves green, and sulfur or lime can be added in small amounts to change the color of the flowers.
Testing the soil’s pH levels and nutrient levels is also advised to ensure proper nutrient availability.

Did You Know?
1. The color of hydrangea flowers can change based on the pH level of the soil they are planted in. Acidic soil (pH below 7) tends to produce blue flowers, while alkaline soil (pH above 7) will yield pink flowers.
2. Contrary to popular belief, hydrangeas don’t require excessive amounts of water. Overwatering them can lead to root rot, and it’s best to keep the soil moderately moist rather than drenched.
3. Banana peels can be a fantastic organic fertilizer for hydrangeas. Simply bury a few banana peels around the base of the plant, and their decomposition will release nutrients such as potassium into the soil, promoting healthy growth.
4. Hydrangeas are excellent bioindicators of aluminum presence in soil. Aluminum ions can change the flower color, so if your hydrangea produces vivid blue flowers, it means your soil has a significant aluminum content.
5. Hydrangea flowers can be dried and used for decorative purposes. To dry them, it’s best to cut the blooms when they are just starting to fade, then hang them upside down in a dry, well-ventilated area. Once dried, they can be used in flower arrangements or even for creating potpourri.

Choosing The Right Fertilizer For Hydrangeas
While specially formulated hydrangea fertilizers are available on the market, they are not necessary for the successful growth of these plants. A good all-purpose fertilizer with a composition of 12-4-8 or 10-10-10 will provide the necessary nutrients for hydrangeas. Both chemical and organic sources can be used as fertilizer, depending on personal preference.
For optimal results, slow-release chemical fertilizers formulated for shrubs and trees are recommended. These fertilizers release nutrients gradually over time, ensuring a steady supply of nourishment for the plants. However, fast-release compounds can also be used if desired.
Alternatively, natural fertilizers can be used to nourish hydrangeas. A successful combination of sulfur, compost, and peat moss can provide essential nutrients without the use of chemicals. This natural fertilizer can be mixed together and applied lightly to the soil around the hydrangea plants.
- Specially formulated hydrangea fertilizers are not necessary
- All-purpose fertilizer with a composition of 12-4-8 or 10-10-10 is recommended
- Chemical or organic sources can be used as fertilizer
- Slow-release chemical fertilizers are optimal for steady nutrient supply
- Fast-release compounds can also be used
- Natural fertilizers like sulfur, compost, and peat moss can be used instead of chemicals
Fertilizing Hydrangeas: Dos And Don’ts
When fertilizing hydrangeas, it is important to avoid overdoing it to prevent fertilizer burn. Over-fertilizing can cause scorched leaves, indicating excess nutrients. To prevent this, it is recommended to use slow-release fertilizers and apply them lightly. Make sure to cover the fertilizers lightly with soil for activation.
For optimal results, hydrangeas should be fertilized in March, May, and July. Spread the fertilizer around the drip line of the branches, where the roots are most active. Before applying the fertilizer, water the hydrangeas well and thoroughly water the fertilizer into the soil afterward.
In addition, a bi-annual dose of liquid iron can help maintain the green and vibrant leaves of hydrangeas, promoting overall plant health and appearance.
Changing Hydrangea Bloom Colors With Soil Amendments
One of the unique features of hydrangeas is their ability to change bloom colors based on the acidity of the soil. If you desire specific colors for your hydrangea blooms, some soil amendments can help achieve the desired hues.
To make hydrangeas blue, sulfur can be added to the soil in small amounts. This can be done by mixing elemental sulfur into the soil or watering the plants with a diluted sulfur solution. It is important to note that the color change process may take time, and gradual changes are recommended to prevent harm to the plants.
On the other hand, if you prefer pink hydrangea blooms, adding lime to the soil can help achieve this color. Like sulfur, lime should be added in small amounts, and the process may take time to yield noticeable results. It is important to keep in mind that white hydrangeas will not change color, as their blooms are naturally white.
To achieve the best results when changing bloom colors, soil amendments should be applied in late fall or early spring. This timing allows the plants to have sufficient time to absorb and respond to the amendments.
Troubleshooting Hydrangea Fertilization Issues
Despite providing the right fertilizer, hydrangeas may sometimes struggle to flourish. In such cases, it is advised to check the pH and nutrient levels of the soil. High nitrogen levels can result in excessive foliage growth, while weak blooms and root systems suffer. High phosphorus levels can hinder the plant’s ability to absorb necessary nutrients, and high potassium levels can lead to irregular leaf growth and rot.
If hydrangeas appear leafy but are not producing many blooms, it may be necessary to skip a year of fertilizing and instead focus on using compost or organic matter to promote overall plant health. Additionally, it is recommended to test the pH levels of the soil to ensure that necessary nutrients are available to the plants.
By following proper fertilization practices and monitoring the health of the plants, you can troubleshoot any issues and ensure that your hydrangeas thrive. With the right care and feeding, these beautiful flowers will reward you with luxurious foliage and stunning blooms.
In conclusion, hydrangea care and feeding are essential for maintaining healthy and vibrant plants. A balanced fertilizer with the appropriate nutrient composition, slow-release properties, and a pH level suitable for the desired bloom colors can help meet the needs of hydrangeas. It is important to fertilize lightly, avoiding over-fertilization that can harm the plants. By following these guidelines and troubleshooting any issues that may arise, you can enjoy the beauty of bright and beautiful hydrangea blooms in your garden.
