Hydrangeas remind me of the hot summer evenings in my Grandmother’s garden. Tall, dense shrubs covered in green, oval leaves with clusters of blue flowers. These hardy shrubs somehow seem old fashioned now. Vintage.
Summer is synonymous with Hydrangea flowers. Visually stunning. Fabulous in a vase.
Sturdy, versatile plants that thrive in both the garden and large pots. Perfect for small balconies or barren areas of the garden.
Traditionally only a handful of varieties were available. My Grandmother had the common French or Large Leaf Hydrangeas with the Blue ‘Mop-top’ shaped flowers. The ones you have to touch. Smell. Snip and place in crystal vases.
Over time different varieties of potted Hydrangeas have evolved, ranging in size and color. I’m particularly fond of the dwarf flowering types. I love the idea of these varieties blooming from Spring to Autumn. Perfect in pots.
Hydrangeas are relatively easy to look after. Thriving in the morning sun and afternoon shade. They only need a good soaking of water. Simple. Here are 4 secrets you need for potted Hydrangeas.
Planting in pots
Hydrangeas are divine in pots. Colorful. Majestic.
When planting these lovely plants in pots, its essential to;
- select a potting mix which enhances drainage
- choose a medium to large-sized pot
- dig a hole in the centre of the potting mix and place the Hydrangea plant inside it
Watering Potted Hydrangeas
During the hot summer afternoons, it is not uncommon to see the Hydrangea leaves wilt and the flowers touching the ground. Desperate for water.
Hydrangeas love water and thrive in moist soil. It is advisable to water the trunk in the early morning before the heat arrives.
It is interesting to watch what happens to the plant when given a decent drenching. Within minutes the leaves and flowers slowly move to an upright position.
- In summer, water daily
- During winter, water once a week
The soil determines the color of your Hydrangea flowers. When the soil is acidic, the Hydrangea will produce an abundance of blue flowers. When alkaline, the flowers will be pink.
I have visions of my Grandfather haphazardly throwing lime near the trunk, in the hope of encouraging the flowers to change to blue. Good in theory. It never worked!
When lime is mixed well within the soil (and not just sitting on top of the ground), it will change blue flowers to pink.
When a sulfur liquid is added to the soil, pink flowers will change to blue.
Pruning Potted Hydrangeas
Many gardeners believe it is important not to prune Hydrangeas. This is ridiculous.
Prune once a year, just before spring. This promotes and enhances growth. During winter your Hydrangea plant will be lush with evergreen leaves.
- Trim off the flower heads that from last season
- Remove the brown and dead stems
The color of Hydrangea plants will be a fabulous addition to your balcony or garden. Ensure they get the morning sun and afternoon shade. They only need a good soaking of water. Simple.
