A natural and organic fertilizer that isn’t just for hollies is called Holly-tone. Any acid-loving plant, including blueberries, camellias, rhododendrons, evergreens, hydrangeas, and others, can benefit from its application.
You should fertilize your plants twice a year, in late fall and early spring. Use only half of the recommended fertilizer dosage when you apply it in the late fall.
Applying Holly-tone:
Be sure to read the back of the package before applying Holly-tone to your acid-loving trees, shrubs, and plants. To offer each variety of plant the best chance to develop, it includes instructions.
Trees:
Determine the diameter of the tree trunk before fertilizing it. This will enable you to calculate the appropriate fertilizer dosage. For every inch of your tree, use one pound of fertilizer.
As shown in the video by Laura, who is using a drill and hole auger to make the holes, drill holes every two to three feet around the tree’s drip line. In essence, the tree’s canopy ends at the drip line. Fill each hole with fertilizer, backfill it, and add water.
Note: Plant-tone should be used in their place because arborvitae and boxwood are not acid-loving evergreens.
Shrubs:
Since there is no need for digging, shrubs are a little easier to fertilize than trees. Similar to trees, the size of the shrub determines how much fertilizer is necessary. For every foot of branch diameter, one cup of fertilizer should be used. It should be dispersed all around the plant’s drip line, worked into the soil, and well watered.
Planting beds:
The three can be fertilized, but established garden beds require the least work. It all comes down to the size of the garden beds you have. Use 5 pounds of fertilizer per 100 square feet of your garden bed. Then, water it in after dispersing it as evenly as you can around the plants.
Use twice as much fertilizer in new garden beds to get the soil ready for new plants. Use 10 pounds of fertilizer for a garden bed that is 100 square feet in size. To prepare the soil ready for the new plants, sprinkle it on top of the soil and work it into the top 4 inches.
Containers:
Use one teaspoon for every three inches of the diameter of your pot if you are growing plants in pots, such as blueberries. Sprinkle it inside the pot’s inner rim, then fill it with water.

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.
Which plants are helped by Holly-tone?
Holly-tone is a fertilizer made specifically for plants that love to grow on soil that is acidic. Azalea, dogwood, rhododendron, ferns, hemlock, holly, hydrangea, juniper, arborvitae, magnolia, Japanese Andromeda (pieris), pachysandra, vinca, and many other evergreens are some examples of plants that thrive in acidic environments.
Dig a hole for new plantings that is roughly twice as wide as the root ball. Don’t add too much compost, humus, or sphagnum peat; current guidelines advise using primarily native soil for backfilling.
Add one cup of Holly-tone and combine well. Holly-tone is a slow-release organic fertilizer that has Bio-tone bacteria added to it, making it extremely safe to use.
Acid-loving plants that are established should be fed twice a year in the spring and late fall. Sprinkle holly-tone everywhere you would season food with salt and pepper. It is best to remove the mulch from the area that needs to be fed, feed it, and then add mulch back on top of that after the plant food has been applied.
For every foot of branch spread on shrubs like hollies, azaleas, and rhododendrons, 1 cup of Holly-tone is used. Whenever the spread is three feet or more, double the amount. Trees like hollies, hemlocks, and junipers use 1 lb* of Holly-tone per inch of trunk diameter in the spring. For diameters 3 inches and larger, multiply the amount by three. Late in the fall, plants should receive a modest feeding. Use only half of the amounts advised for the spring.
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.
Continue reading to find out how to lengthen the time that your hydrangea blooms as well as my personal pick for the best fertilizer for hydrangeas to enhance blossoming.
My plants: Will Holly-tone harm them?
For every 100 square feet of fresh garden bed, Espoma advises using 10 pounds of the herb. The optimum periods to plant azaleas are in the spring and fall, which are also the recommended times for application, as with other trees and plants. If used at the prescribed amounts during planting, Holly-tone won’t burn new plant roots because it’s natural and slow-releasing.
Avoid applying alternative fertilizers that are less organic and more quickly acting while using Holly-tone. Additionally, you shouldn’t plant with them because root burn could result.
Miracle Grow—do hydrangeas like it?
Shrubs that produce big, eye-catching blooms in the summer are hydrangeas. Gardeners who want strong, healthy hydrangeas should concentrate on giving their plants ample sunlight and water. Hydrangeas must also be pruned after flowering in order for the shrubs to produce flower buds for the following year. While hydrangeas don’t require specific fertilization, they do need it to thrive. The Miracle-Gro all-purpose fertilizer is ideal for hydrangeas.
In accordance with the directions on the packaging for the size of your hydrangea shrubs, combine the Miracle-Gro fertilizer and water.
Every other time you water, or roughly every two to three weeks, use Miracle-Gro fertilizer. Aim to avoid getting any fertilizer on the shrub’s foliage as you pour it onto the soil beneath it. This could cause the delicate foliage and blooms to burn. Splashes should be rinsed off right away.
- Shrubs that produce big, eye-catching blooms in the summer are hydrangeas.
- Hydrangeas must also be pruned after flowering in order for the shrubs to produce flower buds for the following year.
After fertilizing, generously water the shrubs to stop the fertilizer from scorching the topmost roots of the plant.
When should hydrangeas be fertilized?
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. Two applications of the fast-release fertilizers are necessary in the summer.
What does hydrangea fast release fertilizer mean?
This Miracle-Gro water-soluble plant food fertilizer is a quick-acting granular feed that will instantly start working on all acid-loving plants, such as hydrangeas. So I can trust Miracle-Gro to deliver results when I’m seeking for hydrangea flowers that are a vibrant blue color. You may prolong the duration of your larger blooms and lusher foliage by using this fertilizer. It functions as a fast-release fertilizer by feeding, providing iron, and acidifying right away.
Use the hydrangea fertilizer once a week or every two weeks for optimal results. Use a sprayer or a watering can, as appropriate. For hydrangeas growing outside, use 1 tablespoon of fertilizer with 1 gallon of water. Mix a half-teaspoon (yes, a teaspoon!) per one gallon of water for indoor plants.
This product is the ideal fertilizer for hydrangeas that need a jumpstart to display color because it works quickly and produces excellent results. After only one application, it has the power to turn hydrangeas from a weak, washed-out blue to a vibrant, natural blue.
I was happy to see that this Miracle-Gro hydrangea fertilizer is available in granular form rather than liquid. It’s a little less messy to handle and easier to control. Using Miracle-Gro to fertilize azaleas, gardenias, or rhododendrons is also a terrific idea.
Holly-tone: Does it turn hydrangeas blue?
- As an easier method of managing soil pH, think about container gardening for hydrangeas. Some of the more recent hydrangea types have big flowers on small, container-friendly plants.
- Hydrangeas grow healthier and have more vibrant colors when they are properly fed. Espoma Holly-tone, which contains sulfur to reduce pH, is a great option for blue hydrangeas. Espoma Plant-tone is the best fertilizer for pink hydrangeas because it doesn’t include any extra sulfur.
- To prevent hydrangeas from wilting, water them regularly, especially during the hottest portion of the summer. Mulch helps retain moisture and keeps roots cool.
- Blue hydrangeas can be very difficult to grow because lime from adjacent concrete patios or pathways can influence their hue. When deciding where to plant, keep this in mind.
- Warning: not all plants enjoy acidic soil. Pay attention to what is growing close to your hydrangeas.
When should Holly-tone be applied?
Evergreens Arborvitae and Boxwood don’t require acidic soils. For them, Plant-tone is advised.
Use when:
- Feed at half as much in the late Fall as you would in the spring.
- The optimal time to fertilize spring-flowering evergreens like azaleas and rhododendrons is when the first signs of bloom color appear.
- Early spring and late spring feedings of berry harvests are recommended (45-60 days apart).
- Fertilizer must never be applied to frozen soil.
Amount to use:
each inch of trunk diameter, one pound. For diameters 3 inches or bigger, double the amount by three. Shrubs:
Per foot of drip line diameter, one cup. If the drip line diameter is three feet or greater, double the amount. Beds:
To prepare a new bed, combine 10 pounds of material per 100 square feet, then work it into the top four or five inches of soil. 5 pounds. should be fed per 100 square feet to established beds.
Container-grown plants in pots:
New Plants: Add 2 cups of Holly-tone per cubic foot of soil when preparing new soil for plants (1.5 tbsp. per quart.)
For established plants, add 1 teaspoon of Holly-tone to the soil along the pot’s outer edge for every 3 pot diameters. Thoroughly water.
How to use:
For bushes:
Around the drip line, sprinkle the necessary quantity, and thoroughly water. If the area is mulched, you can either double the rate on top of the mulch or temporarily remove the mulch and feed the area.
To trees:
Around the drip line, create three holes that are 3 wide, 12–18 inches deep, and Pour the Holly-tone evenly into the holes after dividing it. Fill the holes completely with soil and water.
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.
How frequently should coffee grinds be applied to hydrangeas?
French hydrangeas are admired for their globular blooms, which burst forth in gardens like fireworks displays in the late spring and early summer. Mopheads are normally pink, blue, or white, but if you’re ready to get your hands filthy, you can alter them to your preferred color.
The pH of the soil in which your hydrangeas are planted will determine what color of blooms they produce. The more acidic your soil is (pH less than six), the bluer your blooms will be, while more alkaline soil (pH over seven) will usually produce pinkish flowers. Even hydrangeas with names like Nikko Blue and Nantucket Blue, which can give you the impression that their color is a given, are subject to the pH level of their soil.
You must make sure that your soil is acidic if you want to assure blue blooms. There are fertilizers that can assist you in that endeavor, but other common components can be just as useful and less expensive. Introducing your used coffee grounds. Here’s all you need to know about using used coffee grounds to grow the bluest hydrangea flowers possible.
Which Hydrangea Varieties Can Produce Blue Flowers?
Selecting a cultivar that can yield blue flowers is the first step in realizing your dreams of growing blue hydrangeas. No matter the pH of the soil, the bloom colors of Oakleaf (Hydrangea quercifolia), Annabelle (Hydrangea arborescens), and Peegee (Hydrangea paniculata ‘Grandiflora’) hydrangeas will remain white or ivory. However, the game is on if you have French hydrangeas or lacecaps (Hydrangea macrophylla normalis).
How To Test Soil pH
You can get a kit from your neighborhood hardware or garden supply store to test the pH level of your soil if you haven’t already seen your hydrangeas through a bloom season. With the help of this clever technique, you may also try DIY:
Collect two plastic containers, vinegar, and baking soda to start. Using a hand trowel, place a few scoops of dirt into each container. Next, add half a cup of water to both batches of dirt to wet them. One bowl of soil should receive half a cup of vinegar. Your soil is alkaline if it fizzy. The second container should contain half a cup of baking soda. Your soil is acidic if that mixture fizzes or bubbles in any way.
What happens if neither mixture exhibits a reaction? The fact that your soil is neutral doesn’t necessarily mean that the experiment was a failure. Your soil sample leans closer toward the neutral end of the alkaline or acidic range if your bubbling or fizzing concoction just slightly reacted.
Keep in mind that even without adding an acid-booster like coffee grounds, if your soil is already acidic, you should be able to get some blue blooms. Hooray!
How To Change Hydrangea Color with Coffee Grounds
In the late fall, start incorporating coffee grinds into the soil around your hydrangeas. To help get rid of any unpleasant scent, sprinkle them about your hydrangeas, but make sure to incorporate them into the soil. Just twice or three times a year should be adequate to complete this process.
How Long Will It Take To Turn Hydrangeas Blue?
It won’t produce blue blooms by mid-afternoon if you sprinkle your morning coffee grounds on the soil of your hydrangea plant. It will take some time, and it will take longer if you have brand-new baby hydrangeas that won’t blossom for a few more years. The optimal time to start incorporating coffee grounds into the soil is in the late fall, many months before the blooming season starts. Repeat the procedure according to your regular fertilizer plan.
Your hydrangeas should reward your efforts with the most striking blue globes next spring with a little caffeine and a lot of patience. Just be ready to reveal your secret ingredient to the neighbors—they’ll be envious from the start.
