The Ultimate Guide to Hydrangeas

Hydrangeas are timeless and elegant flowering shrubs that are beloved for their lush, voluminous blooms and striking colors. Whether used in gardens, floral arrangements, or as a special gift, hydrangeas are a versatile and beautiful addition to any setting. In this Petal & Poem guide, we'll explore everything you need to know about hydrangeas - from their varieties and care tips to their symbolic meanings and uses in floral design.

Varieties

Hydrangeas come in several popular varieties, each with its own unique characteristics:
1. Bigleaf Hydrangea (Hydrangea macrophylla): Known for its large, rounded flower clusters, this variety blooms in shades of pink, blue, or white depending on the soil pH.
2. Panicle Hydrangea (Hydrangea paniculata): These hydrangeas feature cone-shaped blossoms and are valued for their hardiness and ability to thrive in various climates.
3. Oakleaf Hydrangea (Hydrangea quercifolia): Recognizable by their oak-like leaves and elongated clusters of white flowers, oakleaf hydrangeas offer stunning fall foliage.
4. Smooth Hydrangea (Hydrangea arborescens): This variety is favored for its easy maintenance and abundant, snowball-like blooms.
5. Mountain Hydrangea (Hydrangea serrata): Similar to bigleaf hydrangeas, these offer delicate, intricate blossoms and are often more compact in size.

Planting and Care Tips

To ensure your hydrangeas thrive and produce gorgeous blooms, follow these essential planting and care tips:

• Location: Choose a location with well-draining soil and partial to full shade, depending on the variety. Morning sun and afternoon shade are ideal for most hydrangeas.

• Soil pH: For pink blooms, aim for slightly alkaline soil. For blue blooms, acidic soil is necessary. You can adjust the pH with additives like lime or sulfur.

• Pruning: Prune hydrangeas right after they finish flowering, removing old wood and spent blossoms to encourage new growth and ensure a healthy shape.

• Watering: Keep the soil consistently moist, particularly during hot, dry spells, but avoid waterlogging.

• Fertilization: Use a balanced, slow-release fertilizer in spring to support healthy growth and flowering.

Symbolic Meanings

Hydrangeas carry diverse symbolism across different cultures, making them a meaningful choice for gifting or decorating:

• Gratitude: In Japan, hydrangeas are associated with gratitude and are often given as a gesture of thanks.

• Understanding: Hydrangeas can symbolize understanding, making them a heartfelt gift for someone in need of compassion and empathy.

• Abundance: With their full, lavish blooms, hydrangeas are linked to the idea of abundance and gratitude for life's blessings.

Care Guide for Cut Hydrangeas in Hot and Humid Cities
Cut hydrangeas are beautiful, but they require special care, especially in hot and humid climates like Hong Kong. Follow these tips to ensure your hydrangeas stay fresh and vibrant for as long as possible.
1. Immediate Care Upon Arrival

• Upon receiving your hydrangeas, carefully unwrap them and trim the stems at a 45-degree angle under running water. This will allow the flowers to absorb water more easily.

• Fill a clean vase with lukewarm water and add floral preservative to the water. Place the hydrangeas in the vase immediately.

2. Water and Moisture

• Hydrangeas thrive in moist environments, so it's crucial to keep the water level in the vase consistent. Check the water level daily and top it up as needed with room-temperature water.

• In hot and humid weather, mist the petals of the hydrangeas with water using a spray bottle once a day to maintain their moisture. Hydrangeas are also one of the only flowers where you can dunk the whole flower into water, and it can drink from its petals.

3. Placement

• Keep the vase of hydrangeas away from direct sunlight and heat sources, such as radiators or electronics. Hydrangeas prefer a cool environment, so pick a cool spot away from drafts and extreme temperatures.

4. Pruning and Refreshing

• Every two to three days, re-trim the stems of the hydrangeas at a 45-degree angle under running water. This helps them to continue taking in water effectively.

• Remove any wilted or faded blooms to encourage the rest of the flowers to flourish.

5. Hydrangeas in Floral Foam

• If arranging hydrangeas in floral foam, ensure that the foam is soaked thoroughly before inserting the stems. Keep the foam moist by adding water every day to the container.

6. Excessive Humidity

• In extremely humid conditions, consider using a dehumidifier in the room where the hydrangeas are placed to reduce moisture in the air.
