How Much Light Do Hydrangeas Prefer?

Hydrangeas are versatile plants that can tolerate both sun and shade, with most preferring morning sun and afternoon shade. The ideal amount of sun exposure for most hydrangeas is 4-6 hours per day, as any more than 6 hours can cause sunburn and other damage to the plants. Some hydrangeas will do well in “filtered” light or a couple of hours of full sun. When choosing a hydrangea to plant for your garden, be sure to choose the right variety and be prepared for the extra watering the plant may need.

Hydroponic plants typically grow best in partial shade, which means you should protect them from direct sunlight. Most hydrangeas prefer only morning sun, but some can tolerate full shade or full sun. The amount of sun they can handle depends on your location, soil pH, rainfall amounts, and climate changes. In areas further north, they can tolerate full sun or partial shade.

Southern gardeners will have the best success growing their hydrangeas in afternoon shade, protecting them from the most intense sun exposure. However, in warmer areas (zones 7 to 9), they do best with morning sun and afternoon shade. All other species grow best in partial shade, getting about 4 hours of sun per day. They prefer full sun in the morning, with some afternoon shade, but many will grow and bloom in partial shade.

To ensure healthy and beautiful hydrangea plants, follow these steps:

1. Choose the Right Location. Most hydrangea plants bloom best in part shade, but some will tolerate full shade or full sun. The amount of sun they can handle depends on your location, so it’s important to choose the right variety and be prepared for the extra watering the plant may need.

What is the best exposure for hydrangeas?

Hydrangeas, commonly known as hydrangeas, prefer partial sun locations, receiving sun in the morning and shade in the afternoon. The Endless Summer® Hydrangea series, such as BloomStruck®, Endless Summer®, Blushing Bride®, and Twist-n-Shout®, prefer part shade. Smooth hydrangeas like the Annabelle Hydrangea also require some shade from the afternoon sun. Bigleaf hydrangeas, also known as hydrangea macrophylla, prefer some shade, especially during the afternoon. For best flowering, big leaf hydrangeas like Nikko Blue and Glowing Embers should get some sun.

Planting hydrangeas in a spot with good drainage, morning sun, and afternoon shade is essential. Most hydrangeas bloom in spring and summer, and can reach heights of 15 feet or higher. They can be grown in pots to decorate patios, apartment balconies, or as a hedge or privacy screen.

Panicle hydrangeas like Fire Light®, Limelight, Pinky Winky®, Strawberry Sundae®, and Vanilla Strawberry® can thrive in full sun. The new reblooming dwarf series, Let’s Dance®, and dwarf big leaf series, Cityline®, grow best in full or part sun. Newer smooth hydrangea varieties, Incrediball®, and Invincibelle® Ruby, are also recommended for full or part sun.

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.

What conditions do hydrangeas like best?

Hydrangeas are best planted in areas with morning sun and afternoon shade, with mature sizes and ample room for growth. They should be planted in areas with excellent drainage and composted soil. Avoid planting under trees, as root competition and lack of sunlight can hinder their growth. Plant hydrangeas in exposed areas with gusty winds. To start, amend the soil with organic matter and an all-purpose slow-release fertilizer. Plant slightly higher than in the nursery container, with a planting hole 2 to 3 times wider than the root ball.

Gently loosen potbound roots before planting, backfill with amended soil, and water well. Space hydrangeas at least 3 feet apart for larger varieties. For pot planting, use bagged potting mix instead of garden soil, mix in slow-release fertilizer, leave 1 to 2 inches between the soil and pot rim, and ensure pots have drainage holes and room for plant growth.

Do hydrangeas like sun or sun?

To prevent hydrangeas from wilting, grow them in dappled sun or shaded areas with gentle morning sun. Regularly water the soil and apply organic mulch over the root zone. Protect the leaves with Yates Waterwise Droughtshield to reduce moisture loss. Hydrangeas thrive in cool to warm temperate climates, but some varieties may tolerate warmer locations. Check the plant tag for specific climate preferences. Cut off spent flowers in late summer and cut stems that have flowered just above a node, where new foliage will develop in spring.

Are coffee grounds good for hydrangeas?

Coffee grounds can be used to change the color of hydrangeas, but it’s best to use aluminum sulfate for a proven flower color change. Crushed eggshells may work, but they should be used with a proven method of raising the pH, like applying garden lime. Vinegar can be added to watering cans to change soil acidity and turn hydrangeas blue, but it’s not a long-term solution and can be harmful to local wildlife.

Are egg shells good for hydrangeas?

Egg shells can be used as a natural fertilizer for vegetables, roses, hydrangeas, spider plants, ferns, and ivy. They can be crushed and sprinkled over containers or garden borders during winter months, or added directly into planting holes. This homemade fertiliser is beneficial for growing vegetables like tomato, pepper, aubergine, roses, hydrangeas, spider plants, ferns, and ivy. A calcium solution can be made by finely crushing egg shells, transforming them into water-soluble calcium that can be easily absorbed by the plant’s root system.

Egg shells can also serve as a pest deterrent, acting as shards of glass around plants where critters gather. They are also believed to deter cabbage white butterflies and cats from using garden beds as litter trays. Overall, egg shells offer a versatile and effective solution for maintaining healthy and thriving plants.

Are hydrangeas best in pots or ground?

Pot-grown hydrangeas can be planted in various locations, including open ground or containers using John Innes compost. Large pots are recommended for long-lasting growth. In open ground, prepare the soil by adding garden compost or organic manure, and 6X Natural Fibrous Fertilizer to boost humus content. Add Vitax Hydrangea Feed or compost when planting for essential nutrients for healthy growth and beautiful blooms. Hydrangeas thrive on most soils and heavy clay, making them ideal for new-build gardens and wet, compacted soils.

Regularly adding organic compost or manure helps hold on to moisture, while mulching the ground around the plants with compost or bark early in the season helps retain moisture. This is done after their annual application of Vitax Hydrangea Feed.

How to keep hydrangeas blooming?

To maximize the number of bright hydrangea flowers in your garden, ensure your plants receive the right amount of sunlight and soil, use a fertilizer designed to increase bloom quantity, and follow a pruning and deadheading routine. Experts like Venelin Dimitrov, Amy Enfield, and David Becker recommend the following tips:

1. Provide the right amount of water: Properly water your hydrangeas several times per week to encourage deep root growth and keep the leaves and flowers dry. Apply water at the base of the plant to keep the leaves and flowers dry, and water in the morning to reduce wilting during the heat of the day.

What do overwatered hydrangeas look like?

Overwatering hydrangeas can result in fewer blooms, wilting leaves, and yellowing leaves. These deciduous shrubs are known for their low maintenance and vibrant blooms. However, common mistakes home gardeners can make include poor soil drainage, which is essential for hydrangeas to thrive.

Hydrangeas prefer well-draining, rich-nutrient soil, which can be improved by adding gypsum to heavy clay soil to improve drainage. If sand-like soil doesn’t retain enough water, peat moss can be used to create a better environment for hydrangeas.

To prevent these pitfalls, it’s important to provide hydrangeas with a comfortable home to settle down in, as they can struggle in heavy clay soil. By addressing these issues, home gardeners can create a healthier environment for their hydrangeas and ensure they receive the necessary care and attention.

How to tell if hydrangea is getting too much sun?

Hydrangeas can suffer from excessive sun exposure in warmer areas, leading to browning of leaves and flower heads. To prevent this, move them to filtered shade or a few hours of morning sun. Even in cooler zones, full-sun hydrangeas need extra watering as they wilt quickly in dry soil. Water regularly, but only when the soil feels dry, and ensure it is well-drained and moist.
