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.
What can I naturally feed my hydrangeas?
Popular flowering shrubs for backyard gardening include hydrangeas. These hydrangea fertilizer suggestions and advice for maintaining your plants’ health can help your hydrangeas look their best.
Organic fertilizer that releases nutrients slowly and is well-balanced can benefit hydrangea plants. Espoma Holly-Tone, Dr. Earth Premium Gold, and Happy Frog Fruit & Flower are some of the top hydrangea fertilizers. Early spring is the traditional period to fertilize hydrangea plants, while early summer is occasionally another opportunity. Light feeding can also be provided by a good organic mulch.
Do hydrangeas require a certain diet?
Like other plants, hydrangeas get their nutrients from soil, water, sunlight, and air. However, not all soil has the nutrients needed for hydrangeas to grow strongly and produce flowers. Hydrangea fertilizer can be useful in this situation. The preferred method of the gardener for applying fertilizer to the soil as well as the state of the existing soil will determine the optimum fertilizer for each particular hydrangea plant.
Type
The three main types of hydrangea fertilizers are liquid, granules, and compacted spikes. All three provide a few minor advantages.
- Liquid fertilizers are readily absorbed by the plant’s roots and leaves for a quick boost of nutrients. They are either available as a concentrate to be diluted with water or as a ready-to-use solution. Liquid fertilizers can either be poured around the base of the plant or sprayed on the plant’s foliage, depending on the product.
- Granules: One of the most popular types of fertilizers, granule fertilizers can either be dusted around the base of the plant or dissolved in water and applied to the soil. With gardening tools, work time-release granules with a polymer covering into the ground close to the hydrangeas’ base. They provide the plant with a steady supply of nutrients and disintegrate gradually.
- When looking for a long-term plant feeding, gardeners frequently utilize spikes, similar to time-release granules. The gardener inserts these compressed and formed fertilizer spikes around the plant’s base in the soil. The spikes gradually disintegrate and supply nutrients to the plants over the period of two or three months.
Organic vs. Inorganic Fertilizers
The majority of fertilizers made specifically for hydrangeas contain chemicals, although some also include natural components. Both are excellent for enhancing the health of the plant and causing it to produce enormous, gorgeous blossoms. It is a matter of personal preference which type you like.
- Inorganic: Chemical and synthetic nutrients are present in this form of fertilizer. It was created in a lab to achieve particular results during the growing process, such as larger or more numerous blooms or a higher acidity level, both of which are preferred while growing hydrangeas. Time-released chemicals, which dissolve gradually and feed the plant over a few weeks or months, can also be found in inorganic fertilizers.
- Organic: Some gardeners choose to use solely organic fertilizers that include components like compost, worm castings, or animal dung. Organic fertilizers don’t include any chemicals and could not be as effective as inorganic ones. Nevertheless, in addition to offering nutritional value, they might also contribute to improving soil health. For instance, compost aids in the drainage of thick clay soil, in addition to giving the plant nutrients.
N-P-K Ratio
Commercial fertilizers are identified on packages by the weight ratio of nitrogen (N), phosphorous (P), and potassium (K) that they contain. An all-purpose, balanced fertilizer with equal levels of each nutrient, like a 10-10-10 N-P-K, will be beneficial for hydrangeas. Both robust blooms and healthy foliage are promoted by a balanced fertilizer. A fertilizer with a higher concentration of phosphorus (the middle number), such as a 10-20-10 N-P-K, may be advantageous for gardeners who specifically want to boost the blooms’ abundance and size.
Plant Needs
The hydrangea loves a fairly shaded area of the yard, however it will withstand some sun. When feasible, place the shrub so that it won’t get direct afternoon sun in a hot environment. Generally speaking, people can tolerate and accept morning sun. Some hydrangeas will also flourish if they receive some early afternoon sun in northern climates with mild afternoon temperatures. These magnificent bushes might suffer from the combination of scorching temperatures and glaring sun. Since hydrangeas want a permanent location in the environment, growing the bushes in pots or grow bags may prevent them from reaching their full potential.
Soil Condition
Hydrangeas do best in soil that is rich in organic matter and has good drainage. Additional organic matter, like compost or dried leaves, will be beneficial for sandy soil and heavy, clay-like soil. The gardener can improve the soil’s phosphorus content and drainage by adding organic matter, which is beneficial for growing vibrant hydrangea blossoms. It’s a good idea to take a sample of the current soil to a nearby extension office for examination before amending it. The test findings will contain suggestions for establishing wholesome, balanced soil.
Color and pH
White hydrangea species exclusively produce white flower heads, whereas colored hydrangeas respond intriguingly to changes in the pH of the soil. The likelihood that the hydrangea blossoms will be blue increases with soil acidity. The pH scale has a range of 0 to 14, with 7 being thought of as neutral. Alkaline levels are those more than 7 and acidic levels are those less than 7. The intensity of the color shift in hydrangeas increases with increasing pH fluctuation.
- Neutral: Colored hydrangea may produce flowers in shades of pink to deep pink at a pH level that is neutral, or around 7.
- Alkaline: Hydrangea blooms have a pale, pure pink tint with pH levels higher than 7.
- Slightly acidic: The blooms take on a dark pink or even slightly crimson or purple tint when the soil pH is about 6.
- Strongly acidic: Hydrangea blossoms frequently turn blue when the pH of the soil is lower than 6. For many gardeners, this is the most desired shade, and they frequently adjust the soil to produce stunning blue flower heads.
You might observe that a sizable portion of the fertilizers for hydrangeas that you purchase are referred to as acidic fertilizers. Acidic fertilizers also have N, P, and K nutrients, as well as pH-altering chemicals like sulfur or aluminum sulfate. It is worthwhile to invest in a pH soil tester to keep track of the pH level of the soil if you want to grow blue flower heads.
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.

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 tons 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 greenhouse 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 neighborhood cats from digging in your flowerbeds. Therefore, pile the material high around your preferred plants to ward off slimy, stingy, or fluffy pests.
Use coffee grinds to alter the color of your hydrangeas. The soil around hydrangeas becomes more acidic thanks to coffee grinds. Chemically speaking, the plant can more readily absorb naturally occurring aluminum in the soil as a result of the increased acidity. Pretty blue flower clusters are the result. Coffee grinds let you play with the color 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 fertilizer. Add a quarter cup of coffee grounds to four or five liters 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.
When do my hydrangeas need to be fed?
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.
Do hydrangeas benefit from tea leaves?
Leslie Vincents of Atkins Garden Shop says, “It’s one of the more unusual gardening methods, but it can work!” (opens in new tab). “Tea and tea leaves are just biological material that is very nourishing.” The tea leaves contain a tremendous amount of nitrogen—far more than typical plant fertilizers—which encourages the growth of highly leafy plants.
Leslie continues, “Brew a pot with two tea bags and let it cool overnight. This is really necessary since you don’t want to pour boiling or even warm water on your plants.”
Our greatest houseplants as well as those in the backyard can benefit from the nitrogen, potassium, and phosphorus in tea. According to Leslie, nitrogen promotes leafy development, thus in principle, burying teabags in the ground, watering plants with cold tea, or scattering dried tea leaves on the ground could make leggy plants appear bushier.
When studying about can you water plants with tea, it’s important to keep in mind that tea also contains other substances that may hinder plant growth. Do keep in mind that these involve aluminum and fluorine.
Additionally, drinking tea might make your soil more acidic, thus using this trick might affect your soil’s pH levels. On plants that thrive in slightly acidic soil, such as poinsettias, hydrangeas, spider plants, and rubber plants, you might test this watering plants with tea trick. But if you want to feed plants that like alkaline environments, stick to regular plant food.
We believe that regular plant watering and the use of common feed provide less health concerns than drinking tea. By using tea instead of measuring out a capful of feed, you run the risk of overfeeding your plants because it is more difficult to determine the amount of nutrients they are receiving.
According to lifestyle blogger and avid gardener Becky (opens in new tab), she watered her plants with a mixture of black tea, cinnamon, and porridge oats that she soaks in water for a whole night. ‘ All of my plants have gone crazy since I did this!
She exclaims, “One plant has grown almost 20 cm in just 3 weeks.” At first glance, this particular inexpensive gardening concept might seem a little crazy, but the whole point of gardening is to figure out what works for you. Perhaps your plants appreciate tea as much as we do.
Are hydrangeas suited for eggshells?
- 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. Fruit peels, grass clippings, peat moss, and pine needles are also believed to have a comparable impact.
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.
To make hydrangeas pink, what should you feed them?
How many of you can recall the argument between the fairy godmothers in Walt Disney’s Sleeping Beauty about the color of the princess’ ballgown? Every time the traditional mophead hydrangeas (Hydrangea macrophylla) bloom in June, I recall that scene. The colors are the stuff of enchantment because they are so vibrant.
Aluminum, not a fairy godmother, controls the color of this hydrangea’s blossoms, whether they are pink or blue. Lack of metal results in pink blossoms, whereas an abundance of aluminum results in blue flowers.
For pink blooms, add lime to the soil; for blue blooms, add aluminum sulfate. The soil composition determines the required amount of lime or aluminum sulfate.
If you are adamant that your hydrangea will be pink or blue, plant it in a container where the pH of the soil may be easily controlled.
