Did You Know?
1. Did you know that Hydrangeas are actually native to Asia, particularly Japan, China, and Korea? They became popular in Europe and North America in the 18th century when they were introduced by explorers.
2. Hydrangeas have the unique ability to change color based on the pH level of the soil. Acidic soil (pH under 6) will typically result in blue or purple blooms, while alkaline soil (pH over 7) will produce pink or red flowers.
3. In the language of flowers, hydrangeas symbolize gratitude, abundance, and heartfelt emotions. They are often used in floral arrangements to express appreciation and sincere feelings.
4. While most hydrangeas are deciduous, meaning they shed their leaves annually, there are a few evergreen varieties that retain their foliage throughout the year. These evergreen hydrangeas are mainly found in warmer regions or protected environments.
5. Hydrangeas are not only admired for their beautiful flowers but also for their medicinal properties. In traditional folk medicine, hydrangea roots and leaves were used to treat kidney stones, urinary tract infections, and various inflammatory conditions.
Different Varieties of Hydrangeas
Hydrangeas are renowned for their stunning clusters of blooms. There are various varieties of hydrangeas, each with its own distinct characteristics. These include compact varieties, double-flowered and bi-colored choices, and those that can bloom on both old and new wood. Moreover, some hydrangeas have scented flowers or feature mesmerizing autumn foliage. An example of a popular variety is the climbing hydrangea, specifically the Hydrangea anomala subsp. petiolaris, which thrives in shaded spots. Understanding the diverse range of hydrangea varieties available can assist in selecting the perfect addition to your garden.

Ideal Growing Conditions for Hydrangeas
To ensure the success of your hydrangeas, it’s essential to provide them with the ideal growing conditions.
Hydrangeas thrive in moist, well-drained soil and prefer dappled shade. If the soil is very dry, avoid planting them in south-facing positions. However, if you have a heavily shaded spot, the climbing hydrangea is the best option.
One of the great benefits of hydrangeas is their adaptability to various soil types, including alkaline and acidic soils. It’s important to note that the pH of the soil can affect the color of the flowers of certain hydrangea varieties.
Planting and Watering Hydrangeas
The best time to plant hydrangeas is in the spring or autumn when the soil is warm and moist. However, planting hydrangeas in the summer is also possible with careful monitoring of moisture levels.
It’s crucial to prepare the soil before planting by adding moisture-retaining organic matter if it’s light. Prior to planting, water the hydrangea well and ensure that you don’t plant it deeper than it was in its original pot.
After planting, mulch the hydrangea with leaf mold, well-rotted manure, or compost. Throughout the growing season, water hydrangeas at a rate of 1 inch per week, especially during hot spells when they are prone to wilting.
Remember to mulch hydrangeas every year in spring to promote healthy growth.

Frequently Asked Questions
Where is the best place to plant a hydrangea?
petiolaris, as it thrives in deep shade. If you want your hydrangea to flourish, choose a location with morning sun and afternoon shade or a spot that receives filtered light throughout the day. Additionally, make sure the soil is consistently moist but not waterlogged, as hydrangeas prefer a well-drained environment. Consider planting your hydrangea on the east or west side of your home for the perfect balance of sunlight and shade.
What month is best to plant hydrangeas?
The ideal time to plant hydrangeas is in the fall or early spring. Fall is particularly advantageous as the plant can take advantage of its approaching dormancy period to adjust and strengthen itself before the following spring’s growth cycle. By transplanting hydrangeas in the fall, they have ample time to adapt and harden off during winter, minimizing the risk of transplanting shock or stress.
How do you start growing hydrangeas?
To start growing hydrangeas, begin by selecting the right time of year, typically during late spring or early summer. Next, cut off a small branch from an established hydrangea plant. Trim the leaves slightly and consider using rooting hormone by dipping the cutting into it. Plant the cutting in seed-starting potting mix and ensure it remains adequately hydrated. Keep an eye out for signs of sprouting, indicating successful propagation. Finally, wait until the cutting has grown sufficiently before transplanting it to its permanent location.
Do hydrangeas grow best in sun or shade?
Hydrangeas thrive in environments that receive full sun or part sun, with at least 4-6 hours of sunlight. However, they can tolerate some shade, as long as they receive morning sun and are shielded from the scorching afternoon sun. So, while hydrangeas can grow in full shade during the hottest part of the day, a balance between sunlight and shade is crucial for their optimal growth and health.
