Things to consider when growing Hydrangeas?
Hydrangeas are not hard to grow but still require some conditions. To keep your hydrangeas healthy and thriving, here are some considerations you need to make:
Soil Preferences for Hydrangeas
Hydrangeas grow better in well-drained soil that retains moisture but does not become waterlogged. The ideal soil pH level for planting Hydrangeas will significantly affect their color. Hydrangeas planted in acidic soil (pH 5.0 to 5.5) create blue flowers, while neutral to alkaline soil (pH 6.0 to 6.5) creates flowers in the shade of pink.
Hydrangeas need well-drained soil to grow. Compacted or overly clay-heavy soil is incompatible because it may cause the roots to rot significantly. To prevent this, it is essential to amend the soil with organic matter like compost and peat moss to improve drainage.
Hydrangea Light Requirements
For Hydrangeas to grow optimally, they need the right amount of sunlight and shade. The ideal light balance is between the morning and afternoon. This is particularly applicable in hot climate conditions.
The amount of sunlight a Hydrangea receives also impacts the color of its blooms. Enough sunlight exposure could deepen the colors of its blooms, especially for varieties like mophead hydrangeas.
Best Time to Plant Hydrangeas
Spring or fall are the best seasons for planting. These seasons are ideal because the moderate temperatures reduce the stress new plants experience.
Before planting, especially in spring, ensure that the risk of frost has passed to maximize plant growth.
Ideal Temperature and Humidity for Hydrangeas
Hydrangeas thrive in moderate temperatures, making them well-suited for gardens with mild climates. The ideal temperature range for their growth is between 60°F and 70°F. They also prefer moderate to high humidity levels, which helps their foliage maintain its health. In Florida, hydrangeas can be successfully planted in areas with partial shade, protected from intense sunlight.
How to Care for Hydrangeas?
Hydrangeas are not hard to grow, but to ensure that they are healthy and bloom the best, follow these instructions:
Water Hydrangeas
Proper watering is essential for hydrangea health. They need about 1 inch of water per week. Water deeply at the base to encourage root growth, and apply 2-3 inches of organic mulch to retain soil moisture and regulate temperature.
Fertilize Hydrangeas
Feeding hydrangeas the right nutrients supports vibrant blooms. To do this, apply fertilizer in early spring and mid-summer. Use a balanced, slow-release fertilizer or one tailored for flowering plants. Avoid over-fertilization, as excess nitrogen can promote leafy growth at the expense of flowers.
Prune Hydrangeas
Regular pruning helps maintain shape and encourages blooming. The timing of pruning hydrangeas depends on their type. Mophead and lace cap hydrangeas are pruned after flowering, while panicle and smooth hydrangeas are pruned in late winter or early spring. Remove any dead or damaged wood and thin out crowded stems for better shape and arrangement.
Propagate Hydrangeas
Take softwood cuttings in early summer, plant them in a rooting medium, and then divide mature plants in early spring or fall.
Pot and Repot Hydrangeas
Container gardening is an excellent option for hydrangeas. First, choose a pot with good drainage holes and repot the plant every 2-3 years or when it outgrows its container.
Protect Hydrangeas in Winter
To ensure your hydrangeas survive, protect them during colder months, especially winter. Apply a thick layer of mulch around the base of your plant, and use a burlap or frost cover to add protection in harsh climates.
Troubleshooting Common Hydrangea Plant Problems
It is normal for any type of hydrangea to encounter problems and diseases. To troubleshoot them earlier, take a look at these common plant problems that occur in hydrangeas and try to study their symptoms to prevent or cure them as early as possible.
Pests and Diseases
Hydrangeas are susceptible to pests such as aphids, spider mites, and scale insects and diseases such as powdery mildew, leaf spot, and root rot. The best way to prevent these problems is to use insecticidal soap for pests, apply fungicides, or improve airflow to combat diseases.
Chlorosis
Signs of chlorosis often include yellowing leaves. This may be caused by Iron deficiency due to high soil pH or poor nutrient availability. To fix this issue, the soil pH must be lowered with sulfur or iron sulfate, and chelated iron must be added.
Flower Color
Hydrangea blooms are influenced by various factors: Adjust pH with lime (for pink) or aluminum sulfate (for blue) and ensure proper light exposure to enhance colors.

Should I cut off dead hydrangea blooms?
Yes, it is a good practice to cut off dead hydrangea blooms, which is also known as deadheading. Depending on the variety, this helps the plant look tidy and encourages further blooming.
How do I keep hydrangeas blooming all summer?
The key to keeping hydrangeas blooming all summer is choosing the right variety. Some hydrangeas, like Endless Summer, are remontant, meaning they can bloom repeatedly throughout the growing season.
How do you keep hydrangeas alive?
To keep hydrangeas alive, provide them with morning sun and afternoon shade, water them deeply 2-3 times a week to keep the soil consistently moist, and use well-draining, nutrient-rich soil. Prune dead or weak stems, and protect them from extreme heat or frost.
