This traditional favorite is a must-have in any garden, and new cultivars have made hydrangea cultivation simpler than ever.
Generally speaking, blue or lavender-blue hydrangea flowers are produced by acidic soil, which has a pH lower than 6.0. Pinks and reds are encouraged by alkaline soil, which has a pH above 7.0. The blossoms turn purple or bluish-pink at a pH of 6 to 7.
Add aluminum sulfate or garden sulfur to your soil to reduce pH levels. Use ground lime to increase the pH. To ensure that the pH of your soil is within the desired range, retest it according to the instructions on the product you’re using.
What can you add to hydrangeas to make them purple?
Grow your plant in its current soil for a year to allow it to reveal its “true colors.” If the blossoms are a deep blue color, your soil likely contains aluminum and is acidic. Simply adding lime and phosphate to the soil will result in purple flowers. By doing this in the fall, you can change the colors for the upcoming growing season. Make a note of how much lime you used so you can later change the colour to your preference.
If the blossoms are pink, test the soil to find out how much aluminum is present and the pH of the soil. If there is a lot of metal in the soil but a high pH, add organic compost to lower the pH. The color will shift toward blue as a result.
It makes no difference whether the pH is high or low if the soil lacks aluminum because the process for altering bloom color is the same. The soil has to be amended with aluminum sulfate. Aluminum is also added as the soil is acidified. Over multiple growing seasons, you’ll need to experiment with the amount you administer to bring the blossoms to your desired shade of purple.
Fungal Disease
Cercospora leaf spot, a prevalent leaf fungus in these plants, can be identified by the presence of purple dots on hydrangea leaves. Although spotted leaves can shed early, weakening the plant and limiting the number of viable buds, plants are rarely killed. Usually beginning at the plant’s base, the tiny purple to brown patches grow outward and upward when water splashes the spores onto adjacent leaves. The type of hydrangea involved determines the specific spotting patterns.
By removing fallen leaves and hydrating your hydrangea at the base, you can stop cercospora from spreading. In a densely packed hydrangea bush, opening the canopy by pruning up to one-third of the branches will improve air circulation and hinder the spores’ ability to germinate. Azoxystrobin, chlorothalonil, mancozeb, myclobutanil, or thiophanate-methyl should be used at intervals of 14 days if cercospora is severe and pervasive.
Phosphorus Deficiency
When hydrangea leaves become purple, the plant may be trying to notify you that there isn’t enough phosphorus in the area to support it. In their haste to alter the hue of their hydrangeas’ flowers, gardeners occasionally unintentionally cause the pH to go so low that other chemical substances bind phosphorus. The inability of bound phosphorus to be utilized by plants deprives them of essential nutrients.
Examine your soil. Alkali soils with pH levels above 7.0 may bind phosphorus with calcium or magnesium, while acidic soils with pH levels below 6.0 frequently allow aluminum to bind the element. The initial step in releasing phosphorus from your soil is to adjust the pH, but if this doesn’t work after a few weeks, you’ll need to fertilize your hydrangea with phosphorus.
Weather’s Influence
The color of hydrangea leaves can also be affected by the weather, resulting in extensive purple discolouration. When the growing season is about to finish, cool conditions may cause the plant to go into dormancy early, allowing the purple color of the leaves to emerge as the green chlorophyll factories stop producing them for the year.
Purple discolouration might also result from frost damage. When the leaves are dry, remove the severely harmed ones, but keep the somewhat harmed ones until new leaves emerge.
How can hydrangeas be made darker?
Like coffee itself, coffee grounds have an acidic pH. The acidity of the soil around hydrangeas is increased by mixing in dried coffee grounds, which enhances the hydrangea’s capacity to produce blue and its capacity to absorb aluminum from the soil. With a pH test kit, track the soil’s pH over time; a range of 5.2 to 5.5 is ideal for blue flowers. Coffee grinds occasionally scattered on the soil’s surface or placed there will slightly raise the acidity level.
What pH causes purple hydrangeas?
Here’s how to modify your soil to change the color of your blooms: pH 5.0 to 5.5 = Blue for soil. pH 6.0 to 6.5 of soil equals pink or purple. Purple, both blue and pink, or both blue and 6.5 in soil pH.
Do hydrangeas’ colors alter when coffee grinds are added?
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.
Does baking soda like hydrangeas?
Ever wondered what happened to your hydrangeas after going outside to check on them? They frequently appear unexpectedly exhausted and wilting, as if they are close to passing away. Your hydrangeas might even appear to get smaller every year. Here’s how to restore hydrangeas and make them seem gorgeous once more!
Everyday Care of Hydrangeas
Make sure you are familiar with the ideal hydrangea daily maintenance. Both location and a nutrient-rich, well-drained soil are quite important. Never overwater them, and don’t fertilize them too frequently. Read my entire post to learn how to take care of hydrangeas. Get ready for the next phase once you have a firm handle on how to care for your hydrangea plants on a daily basis!
The Secret to Revive Hydrangeas
Your hydrangea bushes can be revived with a top-secret chemical, but I’m going to tell you what it is! Although you’ve probably never heard of it, you already have the secret ingredient in your kitchen. Have you prepared? It’s baking soda, of course!
A Little Goes a Long Way
The key is baking soda, but be aware that a little goes a long way. Mix 1 tablespoon of baking soda with 2 cups of water and use it to revive your hydrangeas that have withered. Make sure the baking soda completely dissolves by stirring. Note: This dose is sufficient for 3–4 hydrangea shrubs.
Every two weeks, apply this baking soda treatment. If you only have one hydrangea plant, you can apply the therapy to other weak plants and still get similar results.
Enjoy Thriving Hydrangeas!
You should start to notice more strong hydrangeas in a week or two. The plants start to produce flowers that are fuller and healthier.
Try baking soda if your hydrangeas just aren’t impressing you like they should. Try baking soda in the rest of your garden while you’re at it as well!

Which fertilizer is ideal for hydrangeas?
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.
Does the purple hydrangea actually exist?
Bigleaf hydrangeas’ purple color is frequently misunderstood. The best and most reliable purple hydrangeas are genetically determined to remain purple in acidic soils containing aluminum and never turn blue. As the aluminum is fully metabolized, some varieties may exhibit some purple blooms for one or two seasons, but this typically reflects the soil conditions that were present when those flower buds were developing. The following season, as the aluminum is fully metabolized, the flowers will turn blue.
