In Pots, What Should I Feed Hydrangeas?

Potted hydrangeas are ideal for those with limited garden space due to extreme cold or heat. They typically grow in USDA Zones 3-9, but in either extreme, they may not perform well. Container gardening is a great alternative, as pots can be placed in areas where they are unlikely to grow well. Anne Swithinbank recommends fertilizing hydrangeas in pots with a top-dressing of mulch in spring and a fortnightly feed with a high-potassium fertilizer, such as tomato fertilizer.

Using high-quality, self-watering pots makes hydrangea container gardening a breeze. The constant supply of water keeps hydrangeas looking fresh and healthy. For potted plants, use a slow-release fertiliser like Osmocote or Hortico, which is easy to scatter over the top of the pot. For overwintered hydrangeas, give them fertilizer in early spring and again in May, with no need to fertilize again during summer.

Soil-based compost, such as John Innes No.3, can also be used for hydrangeas. Add a handful of Vitax Hydrangea Feed to the soil or compost when planting to provide essential nutrients for healthy growth. Watering hydrangeas every two to three days or as needed depends on the growing zone and pot size.

To ensure proper growth, use a slow-release generic fertilizer in early spring, with a single annual application sufficient. Avoid applying fertilizer after late July (late summer), as this can promote growth and prevent the plant from going into dormancy correctly. Use high-quality potting soil, preferably with a slow-release fertilizer that will feed the plant the first season, and mix in some compost for optimal results.

Do hydrangeas like sun or shade?

Hydrangeas thrive in full sun to part sun, but can also tolerate some shade. They can be in full shade during the hottest part of the day, especially in hotter climates. However, insufficient sun can lead to reduced flowering and weaker stems. To ensure hydrangeas thrive in their gardens, consider the timing and type of shade. Some hydrangeas are more shade-tolerant than others, so don’t let a little shade hinder your gardening goals.

What can I put on hydrangeas to make them bloom?

To achieve smooth hydrangea flowers, plant them in full sun with moist soil. Water them during drought, especially during summer heat, and amend the soil with organic matter like compost. Prune stems back in early spring just before new growth emerges. It’s essential to know the type of hydrangea you’re growing, as each has slightly different preferences. Follow these general care recommendations and tips for popular hydrangea varieties—panicle, smooth, and bigleaf—to ensure healthy, well-blooming plants.

Planting hydrangeas based on their light preferences is crucial. Dig a hole twice as wide and deep as the hydrangea’s nursery pot, amend with compost for nutritional benefits, and cover the soil with mulch to retain water. Water at least three times a week to establish a strong root system.

Watering hydrangeas is essential, as they need water to maintain their elasticity and prevent drooping or limping leaves in midday heat. Wait until evening to see if the leaves recover before watering, and ensure the soil is moist but not soggy.

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.

What do you feed cut flowers to hydrangeas?

To prepare hydrangeas for a vase, stand them in water for hydration and fill a vase with cold water, ice cubes, and flower food. If you don’t have flower food, dissolve sugar, lemon juice, and bleach in water to create a homemade substitute. Cut the woody stems to help the flowers uptake water, slant them to the desired length, and remove any submerged leaves to prevent rot. Arrange stems to your liking, varying height and position, and add other flowers to the arrangement.

Keep the vase full and check the water daily, mist the flowers to keep them fresh and hydrated, change the water if it starts looking cloudy, rinse the stems clean, and re-cut them before returning them to the vase. Continue to remove spent leaves to keep the bouquet looking fresh longer.

Green hydrangeas can replace foliage for softness and texture, and symbolize lavish beauty and femininity. They fill any vase with vibrant colors and long sturdy stems, creating towering displays. Hydrangeas symbolize friendship, devotion, perseverance, and understanding, and their calming blue shades mean peace and tranquility. Despite their meaning, these opulent blooms are sure to start a conversation and make a lasting impression.

How to turn hydrangeas blue quickly?

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.

Does vinegar help hydrangeas?

The addition of vinegar to watering cans can facilitate the creation of blue hydrangeas by altering the soil acidity. Nevertheless, this approach is not advised due to the potential adverse impact on wildlife and its suitability as a long-term solution for blue hydrangeas.

Is tomato feed good for hydrangeas?

Hydrangeas in pots typically do not require pruning, but they can be fed with liquid tomato feed during the summer months to ensure many flowers. For deeper blue-colored flowers, iron sulphate can be used. In colder climates, additional protection may be needed due to exposed roots, especially on the planters’ edges. A guide on winter hydrangea protection is available. Overwintering hydrangeas in pots in the garage can help maintain cool conditions without extreme freezing or windy conditions. If hydrangeas are in exposed positions, they can be wrapped with horticultural fleece to protect them.

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 is the best fertilizer for potted hydrangeas?

Growing hydrangeas in pots allows them to be moved around and can be used for various purposes, such as decorating a patio or arranging for parties. It is important to choose containers with wheels on the bottom or sturdy plant stands, as they can become heavy after adding dirt and plants. Choose a large container (at least 18-20 inches in diameter) for your hydrangea, as small pots can dry out too quickly, causing the plant to wilt. If your container doesn’t have holes for drainage, drill some into the bottom to prevent rotting.

Choose a variety recommended for your region, as most hydrangeas are hardy in USDA zones 4 to 8, and some can grow in zones 3 and 9. Dwarf hydrangeas may be necessary if your space is limited, as they can get bushy and require pruning. Water your hydrangeas thoroughly when the top inch of the potting mix feels dry, but it’s better to underwater than overwater.

Feed your plants once or twice a year with a slow-release balanced fertilizer, a 10-10-10 granular fertilizer, or commercial, composted manure. Don’t fertilize after July or August if you live in a warm climate, and only once, around June or July, for northern gardeners. Fertilizing later encourages tender, new growth, just when hydrangeas need to start going dormant for the winter.

Don’t fertilize if your plant already looks sick or diseased; instead, try to fix the problem instead. After the flowers finish, snip them off to encourage new growth.

For compact or dwarf hydrangeas to grow in containers, consider varieties like Hydrangea paniculata ‘Little Lime’, Hydrangea paniculata ‘Bombshell’, Hydrangea paniculata ‘Little Quick Fire’, Hydrangea macrophylla ‘Mini Penny’, and Hydrangea macrophylla ‘Buttons ‘n Bows’. These varieties grow to 4 feet tall and prefer full to part shade.

Do coffee grounds help hydrangeas?

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.

What to put on hydrangeas to make them bloom?

To increase the number of panicle hydrangea flowers, plant them in all-day sun or afternoon sun, water them during drought, and add organic matter like compost around the plant. Limit drastic pruning to early spring, just before new growth emerges.

To plant hydrangeas, set them up for success by determining their light preferences, ensuring they can handle part shade to full sun, and ensuring they have well-draining soil. Dig a hole twice as wide and deep as the hydrangea’s nursery pot, amend with compost for nutritional benefits, and cover the soil with mulch to retain water. Water at least three times a week to establish a strong root system.

Watering hydrangeas is essential, as they need water to maintain their health. Check the leaves for signs of dryness and limpness, and wait until evening to see if they recover before watering. Keep the soil moist but not soggy to ensure the plants are healthy and ready to bloom.
