If your soil is alkaline, be sure to amend it to keep the rich blue hue. Use compost, elemental sulfur, or fertilizers designed for plants that thrive in acidic environments to acidify your soil. As they start to decompose and naturally add acidity to the soil, mulching with pine bark or straw will aid over time. In the summer and the first year after planting, keep the soil wet but not waterlogged. Hydrangeas benefit most from a deep watering once per week in hot weather throughout their whole lifespan. Mulching hydrangeas at a depth of about 3 inches is highly advised. Mulching will reduce your plant’s requirement for watering and protect it from harsh weather. For plants that love acid, pick a fertilizer with a delayed release. For optimal results, fertilize once in the spring after the last chance of frost and once again in the early summer. Hydrangeas don’t require pruning, although after they finish blooming, pruning can assist promote bushier growth and rejuvenate an older plant.
Giving your plants the right care is the best defense against illness and pests. The keys to your success are selecting the right place, providing adequate water, and fertilizing.

Blue Nikko hydrangeas: how do you keep them blue?
Although most plants may grow in a variety of soils, others require particular kinds of soil to thrive. Rhododendrons, azaleas, and other ericaceous plants require acidic soils in order to thrive. The soil in your garden must be acidic if they flourish there or in the gardens nearby. Rhododendron leaves turning yellow or disappearing from the area indicate that your soil is likely alkaline. In addition to affecting what you may grow, your soil type can also affect some plants’ leaf and blossom colors; hydrangeas are a well-known example.
Some hydrangea cultivars grow pink or red in alkaline soil and blue or purple in acidic soil. Therefore, if you plant a beautiful blue lacecap or mophead hydrangea in your garden and your soil is neutral to acidic, it will continue to produce blue flowers every year. Even if it was clear blue when you got it, it will flower purple-red or pink if you plant it in alkaline soil the next year.
It is challenging to keep beautiful blue blossoms alive in the open ground, but it is doable if you grow it in a pot; hydrangeas make wonderful topics for pots and containers. Select a pot that is attractive and big, at least 40 cm (15 cm) in diameter. Vitax Ericaceous Compost is the best growing medium for it; plant it there. If you consistently feed your hydrangea, it will thrive on this fertilizer that is specifically made for rhododendrons, azaleas, and other lime-hating plants.
Even though the growing medium begins out being free of lime, repeated watering in places with hard water tends to make it more alkaline. Therefore, add Vitax Hydrangea Colourant, a powder containing aluminum that you may mix with the compost, to ensure that your hydrangea stays truly blue. Each spring, you can also incorporate a small amount into the soil’s top layer and add it to the can when watering your plant.
White hydrangeas, incidentally, don’t change color depending on the type of soil, but they can blush pink in the light.
Feeding and watering
In pots, containers, and during dry spells in the open ground, regular watering is necessary since hydrangeas detest dry environments. When you plant your hydrangea in a bed or border, add lots of garden compost or farmyard manure, and make sure to water well both before and after planting.
The presence of food in the soil is necessary for hydrangeas to grow and produce flowers, even if they are not very demanding plants. In the open ground and in pots and containers, Vitax Conifer and Shrub Fertilizer should be used annually. This is ideal for acid-loving plants and won’t change the hydrangea’s color.
When should you fertilize hydrangeas?
In order to give your hydrangeas an early-season boost, you should typically fertilize them in the spring right before they start to leaf out. During July’s growing season, fertilize them a second time.
When should you prune Nikko blue hydrangeas?
Nikko blue hydrangea shrubs don’t need much (if any) pruning, but if you do feel obliged to do so, the most important thing to know is that they blossom on old wood. Pruning should be done before late summer or early fall when buds are set.
The ideal fertilizer for hydrangeas is what?
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.
Can the color of Nikko blue hydrangea change?
A cultivar of Hydrangea macrophylla known as Nikko Blue may alter its blossom color depending on the pH of the soil. You can select how to modify the soil by using the baseline soil pH from a garden soil test (and change the flower color).
Nikko Blue hydrangea blooms can be dyed a deep blue color with Soil Acidifier. Blue blooms result by lowering the pH of soils with acidifiers like sulfur and gypsum. Until the desired soil pH (4.5–5.0 for blue) is attained, soil acidifiers are normally treated every few months. Some hydrangea fertilizers, including Espoma Holly-Tone, have additional sulfur to assist maintain blue blossoms over time.
Nikko Blue hydrangea blossoms can be made more of a purple/pink color by using garden lime. Dolomite lime and other alkaline soil additives like them boost the pH of acidic soils to make them more neutral. Early spring and/or early fall applications of garden lime are typical to achieve the target pH near neutral.
Do hydrangeas turn blue from coffee grounds?
- Maintain low amounts of phosphorus, moderate levels of nitrogen, and high levels of potassium in the soil in order to make sepals bluer.
- Maintain high levels of nitrogen and moderate amounts of phosphorus while adding garden lime to the soil to give sepals a pinker hue.
- This should be completed in late autumn or early spring, well before flowering.
Can coffee grounds be used to change the color of hydrangeas?
Some gardeners claim that adding coffee grounds to the soil helped them successfully dye their hydrangeas blue. The soil becomes more acidic thanks to the coffee grounds, which makes it easier for the hydrangea to absorb metal. In addition, fruit peels, lawn clippings, peat moss and pine needles, are thought to have a similar effect.
Can eggshells be used to change the color of hydrangeas?
Crushed eggshells might be a good approach to grow pink hydrangeas. Eggshells will gradually degrade and lessen the acidity of your soil, which will make it more difficult for hydrangeas to absorb metal.
How do I make blue hydrangeas with vinegar?
To adjust the soil’s acidity and colour their hydrangeas blue, many gardeners add vinegar to their watering can. However, if you use Hydrangea Blue, a liquid fertilizer that yields blue flowers, you’ll probably get greater results.

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.

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.
Booming hydrangeas in the late summer and early fall.
How to Care for Hydrangeas After Blooming
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.
