When purchasing fertilizer, check the labels to see how much nitrogen (N), phosphate (P), and potassium are present (K). A general-purpose, balanced fertilizer such a 10-10-10 N-P-K or 12-4-8 N-P-K is typically best for hydrangeas. Consider using a fertilizer with additional phosphorus if you want your hydrangea blossoms to be bigger and more numerous.
Since phosphorus is the middle element, fertilizer with the formula 10-20-10 will do. Choose a slow-release granular fertilizer with the designation “bloom boost” if you’re looking into it because it might also include more phosphorus.
Which fertilizer should you give hydrangeas?
Once you understand a few fundamental principles, caring for and feeding hydrangeas is fairly easy. Although it is offered, specialized hydrangea fertilizer is not truly required. All the fertilizing hydrangeas require is an excellent all-purpose 12-4-8 or 10-10-10 formulation. It is possible to use either a chemical source or organic material successfully.
The easiest way to care for and feed hydrangeas is to use a once-per-year slow-release fertilizer designed for shrubs and trees. It will also function with a less expensive fast-release substance. Sulfur, compost, and peat moss are effective hydrangea fertilizers, according to research on how to naturally fertilize hydrangeas.

How frequently should hydrangeas be fed?
The quality of your hydrangeas’ bloom cycle and the quantity of flowers that can cover the plant can both be greatly improved by knowing when and how to fertilize them.
The magnificent hydrangea is a perennial flowering plant that is tough to surpass! It is a preferred option among gardeners because to its large blooms and vivid, colorful leaves. And boy, can they ever generate interest!
It is simple to understand why hydrangeas adorn the gardens of so many homes when you consider that they can thrive in a variety of temperatures (growing zones 37).
But despite how well-liked they are, hydrangeas are also among the plants that people misinterpret the most. In fact, getting them to blossom regularly year after year has undoubtedly vexed many gardeners.
The good news is that encouraging your hydrangeas to bloom on schedule is actually a fairly straightforward process with just a few basic pointers and tips. In light of this, let’s examine the fundamentals of hydrangea maintenance, including when and how to fertilize them for stunning blooms!
The Simple Keys To Big Blooming Hydrangeas
Knowing what type of hydrangea you have is the first step in getting your hydrangeas to bloom vigorously and consistently. When it comes to pruning, different hydrangea varieties demand different care.
As you can see below, when it comes to blooms that are weak or don’t occur at all, that is frequently the main problem.
It is simple to maintain hydrangeas once you are aware of the kind you are cultivating. You will be able to predict when to cut it back and, more importantly, when to fertilize it to encourage large blooms.
First, it’s crucial to understand that a hydrangea that is having trouble blooming may frequently have nothing to do with the soil or lighting. Or, for that matter, how you water or fertilize it.
Simply put, hydrangeas will typically blossom without issue if planted in the appropriate light and in ordinary to good soil. Why then do so many people struggle to get them to blossom or to bloom frequently?
Believe it or not, hydrangeas are frequently pruned at the wrong time, which, more often than you might imagine, results in a lack of flower power.
When To PruneHow To Fertilize Hydrangeas For Bigger Blooms
Hydrangeas in Late Spring/Early Summer Bloom How to Care for Hydrangeas After Blooming
After they have finished flowering, several hydrangea varieties need to be trimmed. These include climbing hydrangeas, Bigleaf, Oakleaf, and even Oakleaf.
On the growth that follows their bloom, they all generate the blooms for the following year. This implies that if you prune them too late or in the fall, you will also be removing the blossoms for the next year.

On the other hand, smooth or panicle variants develop on new growth in the same year. You can prune these in late winter or very early spring because they bloom in the late summer. Pruning these kinds prior to their spring growth is crucial.
Before we move on to fertilizing, one more word about pruning. When it comes to hydrangea pruning, less is more. Actually, they don’t need to be heavily pruned to maintain blooming. The only purpose of pruning should be to maintain shape and prevent the bushes from growing too big. See: Hydrangea Care for Fall
Fertilizing
Giving your hydrangeas the strength and nourishment they require is now the only thing left to do. fertilizing that promotes their growth as well as survival!
When applied at the proper time, fertilizing will increase your blooms’ strength and intensity. Hydrangeas require fertilizer at two crucial times for maximum results. The first occurs in the early spring, right before or during their emergence from hibernation.
Just before your hydrangeas start to bloom and flower is the second time to fertilize them. But the genuine success formula is as follows. For maximum outcomes, each time period necessitates a certain type and technique of fertilizing. In light of that, the following examines both:
A hydrangea benefits from fertilizer in the early spring by becoming greener and more vigorous. This fertilizer must be a low-intensity variety that nourishes the shrub gradually.
The plant’s base can be fertilized with an excellent, all-purpose slow release granular fertilizer or with a strong top dressing of fresh compost, among other options. Lilly Miller All-Purpose Growing Food 10-10-10 is the product link.
The two work together to gradually release nutrients into the soil below. This gradual growth is ideal for steady development, which is crucial to aiding and promoting the forthcoming bloom cycle.
Overly much leaf growth may result from the use of fertilizers that are too potent or do not release their nutrients gradually. Unfortunately, little energy is left over for larger blooms because all of it is going to growing leaves.
Fertilizing Before They Bloom
Hydrangeas should be fertilized a second time, just before they bloom. Again, the type you are growing will determine when they bloom, so that will be a factor.
Give the second dose right before the blooms open if your hydrangeas bloom in the late spring and early summer. The same is true for plants that bloom in the late summer or early fall; once more, they should receive their second dose right before they start to bloom.
The initial spring slow and low dose of fertilizer will not be the same as this dose. You should apply a fertilizer with a higher degree of phosphorus in the ratio rather than a balanced 10-10-10 approach.
A crucial component of bloom power is phosphorus. Additionally, providing this just before the plant blooms will improve the general efficiency of your hydrangea’s flowering cycle. At this time, a 10-30-20 (N-P-K) ratio performs remarkably well. Bloom Booster Liquid Fertilizer product link
It still offers enough nitrogen and potassium, but the addition of phosphorous will make the blooms bigger and more vibrant. Apply the fertilizer and water it thoroughly into the soil to promote soil absorption.

Your hydrangeas will produce heavy blossoms if you fertilize them in early spring and before they bloom. And as the plant develops long-lasting strength, it will continue to work even harder as each year goes by.
Maintaining focus is one of the most important things to remember. The more consistently you feed your hydrangeas the nutrients they require, the more gorgeous flowers you will receive in return. Let’s hope you enjoy your hydrangeas to the fullest this season!
How can I encourage my hydrangea to bloom more?
Early spring or mid-July through late summer are the blooming seasons for hydrangeas. The methods for extending hydrangea blossoms’ life and producing more of them are discussed below.
Plant the hydrangea where it will receive morning light and afternoon shade, keep the soil continuously moist, and treat it in the spring with a fertilizer that is well-balanced to encourage more flowers. To encourage more blossoms, don’t prune your hydrangea too frequently. Hydrangeas bloom on the growth from the previous year.

Should hydrangeas be fed?
Because they are such dependable flowering shrubs, hydrangeas are suitable for gardens of all sizes. Compared to most other plants, they flower for significantly longer periods of time—often months as opposed to weeks. Even after they have gone, the blossoms frequently retain their beauty, giving the garden interest even in the dead of winter. They make wonderful cut flowers as well.
They are simple to grow both in pots and outdoors, which is wonderful news. They only require the right environment, lots of water during dry spells, and sporadic feedings with the proper fertilizer, one that is designed to bring out the best in them.
In the open ground or in pots and containers, pot-grown hydrangeas can be planted at any time of year using Vitax John Innes compost. Pick for good, sizable containers that will enable the plants to flourish for many years. Smaller containers soon dry out.
Prepare the soil thoroughly before planting in open ground by incorporating a lot of garden compost or organic manure to strengthen the soil. To increase the humus content of the soil, which aids in water and nutrient retention in subsequent years, a few handfuls of 6X Natural Fibrous Fertilizer should be forked well into the soil.
When planting, mix a few handfuls of compost or Vitax Hydrangea Feed into the soil. This offers all the necessary nutrients for strong growth and lovely blooms.
The majority of hydrangeas may grow in full sunshine, but they prefer light shade. They thrive in dense clay and flourish in most soil types. They are therefore appropriate for the majority of newly constructed gardens and moist, compacted soils. They prefer plenty of water, as implied by their name, thus adding organic compost or organic manure on a regular basis helps retain moisture. Compost or bark mulch applied around the plants early in the growing season when the soil is moist also aids in moisture retention. Do this after they apply Vitax Hydrangea Feed annually.
The most well-known and colorful kinds of Hydrangea macrophylla are mophead and lace cap hydrangeas. Throughout the season, their flowers frequently change color, and the soil might have an impact on the color of some types. Some are blue on neutral to acidic soil and pink in alkaline environments. Use Vitax Hydrangea Colourant, added to the soil after planting or to the growing media in a pot, to preserve the blue color. Additionally, it can be diluted in water and sprayed on mature plants. However, be patient as this should preserve the color. It does not always function right away.
The compact growth of new hydrangea cultivars makes them perfect for tiny gardens. Many of these produce flowers on both the branches developed in the upcoming season and those from the year before. Consequently, they grow more flowers.
The well-known Hydrangea arborescens ‘Annabelle,’ which grows in a clump of tall stems with soft leaves and sizable frothy, white flowerheads, is another superb garden hydrangea. It looks its best when in bloom and provides a stunning spectacle when under the light shadow of trees.
The popularity of Hydrangea paniculata variants is rising. These bloom in the late summer, producing huge, conical flower heads at the tips of the stalks that are reminiscent of lilacs. The majority are white, occasionally with pink or burgundy flushes. They are ideal for the back of a perennial-filled border.
Leave the flower heads on Macrophylla hydrangeas during the winter, and in the spring, prune each stem back to the first pair of fat buds behind the flower. In the case of old, established plants, some of the older stems can be pruned back all the way to the ground in the winter.
Hydrangeas Paniculata: Hard prune in late winter, reducing by half to two thirds. Maintain a sturdy branch framework at the plant’s base. Strong shoots with flowers at the tips are produced as a result.
Hydrangea arborescens: In the late winter, trim all stems to a height of 15 cm (6 inches). Although this may seem severe, it guarantees strong shoots that should remain upright.
Feed by sprinkling Vitax Hydrangea after pruning, or at any time during the growing season. Feed the area around the plants, hoe or fork it into the soil’s surface, and then liberally water. One of the longest-lasting flower displays in the garden will result from your hydrangeas’ wonderful blossoms and leaves.
How can I maintain healthy hydrangeas?
Although the hydrangea’s leaves and flowers seem delicate, little careful care is actually needed for them. Everything you need to know about caring for hydrangeas is provided in these recommendations.
- Over the course of the growing season, water at a rate of 1 inch per week. To promote root growth, deeply water three times each week. All varieties of hydrangeas benefit from constant moisture, but bigleaf and smooth hydrangeas need more water. To water thoroughly while keeping moisture off the flowers and leaves, use a soaker hose. Hydrangeas won’t wilt as much if they are watered early in the day on hot days.
- To keep the soil around your hydrangeas cool and moist, add mulch. Over time, an organic mulch decomposes, supplying nutrients and enhancing soil texture.
- Apply fertilizer according to the type of hydrangeas you have. Every variety has varied requirements and will profit from applying fertilizer at various times. A soil test is the most effective tool for determining your fertility requirements.
- In March, May, and June, bigleaf hydrangeas require numerous mild fertilizer applications.
- Two applications in April and June work best for oakleaf and panicle hydrangeas.
- The only time smooth hydrangea plants require fertilizing is in the late winter.
- By selecting cultivars with resistant characteristics, you can avoid pests and diseases. Hydrangeas can have leaf spots, bight, wilt, and powdery mildew. Although they are uncommon on hydrangeas, pests might arise when the plants are under stress. Aphids, leaf tiers, and red spider mites are examples of potential pests. Properly caring for hydrangeas is your greatest defense.
