Hydrangea Cultivation Tips For Hot Climates?

Hydrangeas are known for their ability to thrive in cool, moist shade, but some types are more heat and drought tolerant than others. If you live in a warm, dry climate, you can still grow hydrangeas in zone 9 gardens. Oakleaf hydrangeas are heat-tolerant and grow best when given morning sunlight and a little afternoon shade. However, gardeners in hot climates often struggle to keep these plants thriving during intense heat events.

To ensure the best care for hydrangeas, follow these tips:

1. Plant in spring after the last frost in cooler climates to allow time for establishment before the hot summer months.
2. Plant in fall in warmer climates in the fall.
3. Water deeply prior to the heat event to keep the root zone well-hydrated. Place mulch around plants to keep in moisture.
4. Amend soil with organic matter before planting. Avoid applying fertilizer prior to a heat event.
5. Avoid transplanting hydrangeas in hot weather as they may suffer from transplantation. Most plants don’t mind ambient heat too much as long as they are sheltered and their soil is moist.
6. Panicle hydrangeas can handle hot sun, but panicle hydrangeas (Hydrangea paniculata, Zones 3-8) are the most sun-tolerant species available. By following these tips, you can ensure your hydrangeas thrive in your warm climate.

Where is the best place to plant hydrangeas?

Hydrangeas thrive in moist, free-draining soil and dappled shade, but should be avoided in south-facing positions, especially if the soil is very dry. For shaded vertical surfaces, grow the climbing hydrangea Hydrangea anomala subsp. petiolaris. Young growth is prone to frost damage in spring, so plant away from strong winds. Hydrangeas can thrive in alkaline and acidic soil, but the pH of the soil can change the color of some varieties, such as pink flowers appearing blue in acidic soil. The best time to plant hydrangeas is in spring or autumn, when the soil is warm and moist.

Why are my hydrangeas wilting in the heat?

In hot weather, hydrangeas, particularly blue/pink bigleaf or “French” hydrangeas, tend to wilt or droop due to their rapid transpiration of water vapor from their leaves. This fatigue is not alarming as long as the hydrangeas can rehydrate overnight and appear refreshed by morning. If the hydrangea still looks wilted, it’s recommended to increase watering. Bigleaf hydrangeas are the worst offenders, while smooth and oakleaf hydrangeas can withstand more sun.

However, panicle hydrangeas, which require six or more hours of sun to bloom their best, are the most wilted. These varieties require plenty of sun and water to bloom their best. To avoid a wilted landscape, consider adding panicle hydrangeas to your landscape.

How do you keep hydrangeas alive in the sun?

To care for hydrangeas in full sun, prioritize water as the main priority. Use mulch to increase water retention and use a water meter to check soil moisture before watering. Hydrangeas thrive in moist soil with oxygen, not drowning in it. A water meter can help determine when to water. If your dream of growing hydrangeas in a full sun garden spot isn’t feasible, you can still create a bold floral display with large-bloomed beauties. Check out a video on water meters for more information.

What is the best fertilizer for hydrangeas?

Hydrangeas thrive when fed a balanced or all-purpose fertilizer, such as 10-10-10 NPK or 12-4-8 NPK. Fertilizers formulated for roses are also suitable. Spring is the best time to fertilize hydrangeas, as they are known for their large flower heads and attractive colors. Fertilizer and soil amendments can change the color of bigleaf or mountain hydrangea types. Hydrangeas only need fertilizer a few times a year, so it’s essential to know the variety you have. Some commercial fertilizers can change the color of hydrangea flowers from pink to blue, which can be surprising if not expected or planned for your garden.

Why is my hydrangea wilting and looks like it is dying?

Winter cooping can cause wilting leaves due to oversaturated soil causing root rot or potted hydrangea being too root-bound to take in enough water. To address this, remove the hydrangea from its container, examine its roots, trim off any root-bound ones, and repot them in a clean container with fresh potting soil. If the roots are brown-black and slimy, it’s root rot. Trim the roots back to healthy levels, repot in a clean container with good drainage holes, and water sparingly. Sterilize garden tools after repotting and choose a shaded area to prevent sunscalding.

Do hydrangeas like coffee grounds?

To change the color of hydrangeas, start by adding coffee grounds to the soil around them in late fall. Work the grounds into the soil to eliminate any off-putting smell and do this two to three times per year. It will take time to turn hydrangeas blue, especially for new baby hydrangeas that may not bloom for a couple of years. Start adding coffee grounds months before the blooming season begins, ideally in late fall. Repeat the process with your regular fertilizing schedule. With a little caffeine and patience, your hydrangeas should reward your efforts with bold blue globes in the spring.

Are eggshells good for hydrangea plants?

Crack eggs and rinse the eggshells to feed them to flowering bushes. Microwave the shells for 3 minutes to sterilize them and dry them. Crush the shells and sprinkle the powder near rhododendrons and hydrangeas. The calcium boost the eggshells provide will help plants thrive.

How do you revive hydrangeas in hot water?

To revive hydrangeas, boil water and cool slightly. Cut the hydrangeas at a 45-degree angle and place them in a vase filled with hot water. Allow the hydrangeas to sit for at least an hour before repotting. Hydrangeas, derived from the Greek words “hydor” meaning water and “angos” meaning jar or vessel, require water to survive. Their woody stem can make it difficult for them to obtain the necessary water. Trim the stems at an angle and add a small slit to help them absorb more water. This simple hack can help bring your hydrangeas back to life.

What is the most hardy hydrangea?
