Both the method and the fertiliser used while fertilising hydrangeas are crucial. Burning from fertiliser can happen when too much is used. The first indication of over fertilisation is scorched-looking leaves. Fast-release fertiliser needs to be lightly applied to hydrangeas in March, May, and July.
Make sure to distribute it along the branches’ drip line rather than their base. Water wisely. Remember to lightly cover the fertiliser with soil to activate it if it is a slow-release variety. Add a small amount of liquid iron every two years to maintain the leaves’ vibrant green colour.
Without noting the use of modest amounts of sulphur or lime when fertilising to modify hydrangea colour, a discussion of how to fertilise hydrangeas would be incomplete. Sulfur-treated hydrangeas can stay blue or turn that colour. Pink is produced by lime, and it takes time for any colour to change. Please be aware that white hydrangeas won’t turn colour.
Hydrangea maintenance and feeding should be done properly to ensure lush foliage and beautiful blooms.
Which fertiliser is ideal for hydrangeas?
When purchasing fertiliser, check the labels to see how much nitrogen (N), phosphate (P), and potassium are present (K). A general-purpose, balanced fertiliser such a 10-10-10 N-P-K or 12-4-8 N-P-K is typically best for hydrangeas. Consider using a fertiliser with additional phosphorus if you want your hydrangea blossoms to be bigger and more numerous.
Since phosphorus is the middle element, fertiliser with the formula 10-20-10 will do. Choose a slow-release granular fertiliser with the designation “bloom boost” if you’re looking into it because it might also include more phosphorus.
How frequently do my hydrangeas need fertiliser?
Fertilizing hydrangeas once or twice in the summer is optimal for their growth. Despite the fact that some experts advise using specialised fertiliser blends to achieve the best results, hydrangeas thrive when given a more casual approach.
It is possible to use organic matter or chemical fertilisers successfully. This would be a fantastic first line of defence because putting manure and/or compost organically around the roots yields outstanding effects and also improves the soil’s quality. For optimal impact, organic soil improvements can also be paired with a dose of chemical fertiliser.
The simplest method, if chemical fertilisers are employed, is probably to apply a slow-release, balanced fertiliser once a year. The market is flooded with slow-release fertilisers. If you can locate a fertiliser made for trees and shrubs, it would be effective on hydrangeas. In order for the fertiliser to release efficiently when Osmocote is applied, the granules MUST BE covered with soil.
Slow-release fertilisation is by no means the only method for hydrangeas, though. If used twice over the summer, a less expensive fast-releasing fertiliser such a 10-10-10 will perform just as well. A soil sample should be taken and the fertiliser and trace elements should be matched to your soil’s requirements if you want a fertilising regimen that is personalised to your particular circumstances.
Fertilize no later than August. Hydrangeas start preparing for dormancy in the fall. By fertilising now, you can encourage sensitive new growth that won’t be able to weather the winter. A late May application and another in July might be appropriate in the South. Northerner regions might want to fertilise just once in June or July.
The size and root system of the plant will determine how much chemical fertiliser is utilised per plant. If growing hydrangeas in a container, use less fertiliser. More harm can result from overfertilization than from underfertilization. When too much fertiliser is used, it can cause “fertiliser burn,” which damages or even kills the hydrangea by drying out the roots. To be on the safe side, use less fertiliser than you think is necessary. The first indicator of damaged roots is frequently leaves that seem charred. In severe cases of overfertilization, the plant may simply wilt and die.
Knowing that a very small plant will require between 1/8 and 1/4 cup of fertiliser when it is planted in the ground may be useful if you are new to growing plants. Apply a fertiliser with caution that won’t burn the roots when fertilising hydrangeas in pots (such as a slow release or a liquid fertilizer). Two to three cups should be distributed around the drip line of the branches of a very large shrub planted in the ground (not next to the trunk). Please read the fertilizer’s instructions carefully before using it because this is only a very rough estimate.
For both plants in pots and plants in the ground, liquid fertiliser should be applied once a month if it is being utilised.
If a plant appears sick or wilted, never fertilise it with a chemical fertiliser. A plant will only experience more stress if the cause of its difficulties is a disease or a root issue. Prior to putting in fertiliser, try to solve the issue.
When should I fertilise my hydrangeas?
- In March, May, and June, bigleaf hydrangeas require numerous mild fertiliser applications.
- Hydrangeas Oakleaf and Panicle should receive fertilisation twice, in April and in June.
- Late winter is the ideal time to fertilise Smooth Hydrangeas.
In order to give your hydrangeas an early-season boost, you should typically fertilise them in the spring right before they start to leaf out. During July’s growing season, fertilise them a second time. Two applications of the fast-release fertilisers are necessary in the summer.

When is it too late to fertilise hydrangeas?
Two times a year, in early spring (May) and early summer, fertilise hydrangeas (July). You can apply fertiliser with an NPK ratio of 10-10-10 or 15-30-15 on the majority of hydrangea varieties.
The use of fertilisers with greater phosphorus concentrations, also known as “bloom boosters,” is a popular alternative. They are often used following the first bloom of the season and promote strong flower growth.
Can hydrangeas be fertilised when they are blooming?
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 fertilise them.
The magnificent hydrangea is a perennial flowering plant that is tough to surpass! It is a prefered option among gardeners because to its large blooms and vivid, colourful 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 fertilise 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 fertilise 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 fertilise 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 fertilising, 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. fertilising that promotes their growth as well as survival!
When applied at the proper time, fertilising will increase your blooms’ strength and intensity. Hydrangeas require fertiliser 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 fertilise them. But the genuine success formula is as follows. For maximum outcomes, each time period necessitates a certain type and technique of fertilising. In light of that, the following examines both:
A hydrangea benefits from fertiliser in the early spring by becoming greener and more vigourous. This fertiliser must be a low-intensity variety that nourishes the shrub gradually.
The plant’s base can be fertilised with an excellent, all-purpose slow release granular fertiliser 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 fertilisers 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.

Your hydrangeas will produce heavy blossoms if you fertilise 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 fertiliser 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.

Are hydrangeas suited for coffee grounds?
Coffee has always been amazing to me. If not magical, then pretty close. I mean, I’m a writer, and I’m pretty convinced that writers account for at least half of the sales in the coffee industry. But this also means that every day, we throw away tonnes of used coffee grounds. Although coffee grounds alone are not very harmful to the environment—in fact, I’ll teach you how to use them in your yard in a moment—they do add to the volume of landfills. Coffee, ever the sociable drink, mixes with other trash in foul trash heaps to produce methane, which as we all know is a glasshouse gas that contributes to climate change. So the next time, try something a little different rather than simply throwing the grinds in the trash.
If you just drink one pot of coffee per day, you will have a lot of wonderful, mineral-rich grounds left over after you finish your first pot of the day, which you can use to enhance your garden. We coffee aficionados enjoy the strong coffee fragrance, but insects that harm flowers respond negatively to it. Coffee grounds not only deter ants and snails, but they also stop neighbourhood cats from digging in your flowerbeds. Therefore, pile the material high around your prefered plants to ward off slimy, stingy, or fluffy pests.
Use coffee grinds to alter the colour of your hydrangeas. The soil around hydrangeas becomes more acidic thanks to coffee grinds. Chemically speaking, the plant can more readily absorb naturally occuring aluminium in the soil as a result of the increased acidity. Pretty blue flower clusters are the result. Coffee grinds let you play with the colour to transform pinker blossoms into other shades of blue, or perhaps a shade of purple in between, even if coffee won’t influence the brilliance of the flowers (pale blue flowers will remain pale blue, for example).
Coffee contains nitrogen, which helps plants grow, so give your plants a boost by turning the grinds into a natural fertiliser. Add a quarter cup of coffee grounds to four or five litres of water to make a “tea of coffee grounds.” Pour the liquid over all of your plants the next morning for a nutrient boost after letting it set overnight.
