How Do I Get More Blooms From My Hydrangeas?

Hydrangeas are a versatile plant that thrive in both sun and shade, so it’s essential to find a spot that gets both. They are thirsty plants, so it’s crucial to water them regularly but not drown them. To increase the number of bright blooms on your woody hydrangea shrubs, ensure they have the right amount of sunlight and soil, a fertilizer designed to increase bloom quantity, and a pruning and deadheading routine that keeps them flowering all season long.

To ensure proper pruning, choose the right plant for your zone and protect tender flower buds of susceptible hydrangeas from extreme cold by building an insulative cylinder around the shrub in late fall. Additionally, consider offering more sun or shade, reconsider watering, and consider pruning your plants.

Hydropony is the best way for hydrangeas to bloom, so it’s important to give them enough room to grow into their mature size. Improper pruning, or the accidental removal of flower buds, can lead to failure to bloom. To get abundant hydrangea blooms, add compost or other organic material to the soil as a fertilizer. Hydrangeas do best when given full sun, especially if their leaves start to droop. Poor-draining soil can also hinder blooms.

In addition, using an acidic fertilizer formulated for blooming plants can encourage additional blooms. By following these tips and tricks, you can maximize the number of blooms on your hydrangea plants this year.

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.

What does Epsom salt do for hydrangeas?

Epsom salt, also known as magnesium sulfate, is a popular gardening hack that claims to improve growth, flowering, and deter pests. It has been a part of gardening folklore since before the internet. However, the science behind these claims is scarce. While Epsom salt is recommended for various garden issues, such as enhancing growth and flowering, acting as a fertilizer, deterring pests and diseases, and resolving various growth problems, there is little evidence to support these claims. Therefore, it is essential to carefully consider the potential harms of applying Epsom salt to your hydrangeas.

What is the best fertilizer for hydrangeas to bloom?

Organic, slow-release fertilizers for roses and hydrangeas are suitable for increasing the size and quantity of their blooms. Rose fertilizers, such as 15-10-10 or 10-5-5, provide the necessary nutrients for healthy growth, while hydrangeas require balanced fertilizers with a 10-10-10 ratio for healthy growth.

Growers often ask if they need to purchase different types of fertilizer for multiple hydrangea types. The answer is no, as the same type of fertilizer can be used for all types. However, adjustments may be needed if enhancing or changing the color of specific hydrangea blooms.

However, some types of fertilizer can cause harm, and Natalie Carmolli of Proven Winners® ColorChoice® Flowering Shrubs advises against using acidic fertilizers.

Is Miracle-Gro good for hydrangeas?

Water-soluble fertilizers, such as MiracleGro®, can be used to improve the bloom color of hydrangeas, particularly for new plantings or those recovering from stress. This high phosphorous level is not ideal for a sustained “blue” hydrangea fertilization program, but it can be beneficial for spot use and reviving stressed plants. Bloom color manipulation is only achievable with H. macrophylla and H. serrata, and is most associated with plants with mophead bloom form.

The primary soil component for making blue blossoms is the presence of aluminum in the soil, and pH is closely relevant. Bloom color can be substantially altered depending on soil pH, but should not be overdone. Cultivars with pale bloom pigment can be adjusted between pink and blue, while medium to dark blue varieties like Mathilda Gutges can be decent fuchsia pinks but more brilliant in their normal purple-blue hues via aluminum sulfate.

How do you perk up hydrangea blooms?

To prevent wilted hydrangea blooms, give them an ice bath by filling a sink with ice cold water and submerging the entire stem, flower head, and leaves for at least a couple of hours or overnight. Prepping your hydrangeas before cutting ensures they stay fresh from the start. Grow ideal varieties, such as bigleaf, oakleaf, and panicle hydrangeas, which are naturally better suited to producing wilt-resistant flowers. Some versions like lacecaps are less likely to last, while bigleaf, oakleaf, and panicle hydrangeas offer the best staying power when cut fresh.

What is the best bloom booster for hydrangeas?

To maintain a healthy bloom cycle, it’s crucial to feed Hydrangea with slow-release, granular fertilizers like Plant-tone® + Iron-tone® or Holly-tone® + Iron-tone® in spring and midsummer. For a bloom boost, apply Triple Phosphate as per package instructions. Proper care, including sunlight, pruning, winter protection, and fertilizing, is essential for hydrangeas to bloom their best.

What does apple cider vinegar do to hydrangeas?

Acid-loving plants like hydrangeas can be treated with apple cider vinegar and water. This vinegar, made from fermented apple juice, contains vitamins and minerals but is particularly beneficial for acid-loving plants like blueberries, cranberries, azaleas, northern bayberries, and rhododendrons. Its 5% acidic content makes it a great treatment for these plants, as well as some trees like conifers and pecans that prefer acidic soil. The vinegar’s potent acidity can dissolve pearls, making it a great addition to any garden. Proper storage and use of vinegar can help maintain the health and beauty of these plants.

How do you get hydrangeas to bloom full?

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.

Why isn’t my hydrangea blooming?

Hydrangeas often fail to bloom due to various factors, including incorrect pruning, bud damage from winter or early spring weather, location, and excessive fertilizer. Hydrangea varieties can bloom on old wood, new wood, or both. For example, a Nikko Blue Hydrangea produces blooms in the fall, which should not be pruned to the ground in the fall when cutting back perennials. Endless Summer, a hydrangea variety that blooms on both old and new wood, should not be pruned in the fall as it may cut off some of next spring’s blooms.

The plant tag on the hydrangea will indicate whether the plant blooms on old wood, new wood, or both. It is best to wait and prune your hydrangeas in the spring, as stems that lack leaves and are brittle when bent should be pruned near the base of the plant, as they will not produce any blooms.

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.
