When planting hydrangeas, it is essential to choose the right variety and location for your garden. Hydrangeas thrive in moist, free-draining soil and dappled shade, but should not be planted in south-facing areas. Instead, choose an east- or north-facing location with relatively constant temperatures, as these areas typically heat up in winter sun, making buds. Hydrangeas typically grow best in USDA zones 3 to 9, but this depends on the specific cultivar you are growing.
Plan to plant in the spring after the last frost or in the fall before the first frost to give the shrub plenty of time to establish a healthy growth. The best location for hydrangeas is one that receives morning sun and afternoon shade, with more sun if you live further north. Most species prefer partial shade, given a few hours of morning sun with some protection in the afternoon. A spot under a tree canopy that receives dappled shade is also suitable.
Soil type: Grow hydrangeas in moist, fertile soil, and they are happy in clay. Plant them in a cool, semi-shady part of the garden, avoiding exposed areas. Hydrangeas do best in partial shade and dappled shade, and can tolerate full shade in the afternoon as long as they receive sun in the morning. However, too much shade can cause flowering issues and weaken stems.
Ideally, plant your shrubby hydrangea in light shade, away from frost pockets or exposed spots to reduce late frost damage. Hydrangeas grow on most soils and thrive on heavy clay, making them ideal for most gardens. The best location for most hydrangeas is the east side of your home, but this will depend on your growing location and the structures of your home.

What to put on hydrangeas to make them bloom?
To achieve bigger hydrangea blooms, use a “bloom booster” fertilizer with a high level of phosphate, like osmocote. However, too much fertilizer can hinder blooms. Additional plant food can be used throughout the growing season, but too much nitrogen in spring may reduce flowering. Deadheading is a process where spent flowers are removed from hydrangeas when they fade to make way for new, fuller blooms.
If planted in the right location and given ample space, the only trimming needed is to remove deadwood and dried blooms. Early removal may encourage a second flush of blooms, as hydrangeas that flower on new wood may sometimes flower again.
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.
Should I cut my hydrangea blooms?
Deadheading hydrangeas is a simple and beneficial gardening task that prevents the production of seeds and instead focuses on root and foliage development. Expert gardeners at Millcreek Gardens explain how to deadhead hydrangeas, when to do it, and how to protect them after the blooming season. Deadheading requires garden gloves, pruners, and a container to hold faded flowers. This easy task is enjoyed by many gardeners and can be done with a pair of pruners.
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:
- 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.
Do coffee grounds help hydrangeas bloom?
Hydrangeas’ color is influenced by the acidity of their soil. The more acidic the soil, the more blue the blooms. To achieve the best blue hydrangea blooms, add coffee grounds to the soil. The pH level of the soil is crucial for hydrangeas to bloom. Higher acidity results in bluer blooms, while more alkaline soil produces pinkish flowers. Some hydrangea names, like Nikko Blue and Nantucket Blue, are influenced by their soil’s pH level. French hydrangeas are known for their globe-like blooms, which can be manipulated to suit color preferences.
To ensure blue blooms, ensure the soil is acidic. Fertilizers can help, but leftover coffee grounds can be just as effective and cost-effective. French hydrangeas are prized for their globe-like blooms, which can be manipulated to suit individual preferences.
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 month is best to plant hydrangeas?
Planting hydrangeas in the Southeast is best done in the fall due to less harsh conditions and the absence of leaves. However, planting in early spring after the last frost can be challenging due to the tough growing conditions of the season. Hydrangeas need morning sun and afternoon shade for optimal blooming, but they will not tolerate hot afternoon sun. To ensure the best planting location, watch your landscape for a few days to ensure the area receives shade during the hottest part of the day.
It is essential to keep hydrangeas well-watered throughout the season, as they need to endure the toughest growing conditions. Overall, planting hydrangeas in the fall is a wise decision for optimal growth and health.
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.
Can hydrangeas be planted next to a house?
Two feet of spacing between hydrangeas is likely too close, especially near your house, which can cause them to become crowded. It is best to have shrubs have a couple feet of clearance near the house walls. The type of hydrangea you bought can determine the spacing, with some growing up to 10 feet and others 5-6 feet apart. Endless Summer, a newer variety, is planted about 3-5 feet apart and can bloom on both new and old wood. Older types bloom only on old wood and may bloom the following summer in harsh winters.
If you have any plant tags, check the Lowes website for typical plant tags. To increase the distance, lift some hydrangeas and group them in groups of 3 or five. Hydrangeas have shallow roots, making them easy to transplant.
Where is the best place to plant my hydrangeas?
Hydrangeas thrive in moist, non-waterlogged soils and can be grown in sun or light shade in sheltered areas. However, they can be prone to leaf scorch and poor flowering in dry soil and full sun. To avoid frost damage, plant away from frost pockets and scorching wind. The flower color of some hydrangeas, such as mophead and lacecap cultivars, depends on the soil’s pH, which is affected by aluminium availability. Those with naturally blue or pink flowers are bluest in acidic soil, mauve in slightly acidic to neutral soil, and pink in alkaline conditions.
Where do hydrangeas grow 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.
