Espoma’s Holly-tone is an all-natural, organic fertilizer that can be used on other plants as well. 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. Holly-tone is a natural organic product that has been utilized by professionals for many years. Additionally, it contains Bio-tone, which improves the organic fertilizer biologically for better plant growth.
Applying Holly-tone: Be cautious to read the bag’s back before fertilizing trees, shrubs, and other plants that love acid. To give each sort of plant the best chance to grow, it provides instructions.
Trees: Measure 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 seen in the video by Laura, who uses a drill and hole auger to make the holes, drill holes every 23 feet all the way 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: Espoma’s Organic Plant-tone should be used in their place because arborvitae and boxwood are not acid-loving evergreens.
Compared to trees, shrubs are a little easier to fertilize because no digging is necessary. 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.
Garden Beds: Of the three, fertilizing established garden beds is the easiest. 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 ten 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.
Pots: Use one teaspoon for every three inches of the diameter of your pot for growing plants like blueberries in containers. Sprinkle it inside the pot’s inner rim, then fill it with water.
Holly-tone will it turn hydrangea 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.
Can I spray Holly-tone in the summer on hydrangeas?
For those of us who live in northern climes with more severe winters, The Endless Summer series represents a milestone in hydrangea breeding.
Older hydrangea kinds only produced flowers on old wood or stems that had grown the previous year. All flowers for the following season were gone once that growth was destroyed due to harsh winter circumstances, damage, or unintentional autumn trimming.
The plants in the Endless Summer series are significantly more adaptable in the environment because they bloom on both new and old wood. The plants won’t generate many, if any, buds on the growth of the current season, though, if the plants are not properly nourished in the spring.
Any Endless Summer variety will grow best in an easterly direction or in a spot in the garden that receives morning sun and afternoon shade. To make a richer soil that will store nutrients and fertilizers better and retain more moisture, use a decent compost.
Use Plant-tone and granular lime for purple to pink blossoms or Holly-tone and holly for blue flowers when fertilizing your Endless Summer Hydrangeas in the spring.
We advise fertilizing in April, May, and June with 1 cup of fertilizer for every foot of branch spread for the optimum flowering. For instance, 9 cups of fertilizer would be applied over a three-month period to a plant that is 3 feet broad. After this time, fertilizer shouldn’t be used to plants.
Continual Summer Fall is not the time to prune hydrangeas. Rather, only prune them in May. This will guarantee that the flower buds that survived the winter have opened.
Plants marked with a number sign (#) and a number are generally the same size as gallon pots; for example, #2 is equivalent to a 2 gallon pot, #3 to a 3 gallon pot, and so on. These plants are offered for sale in pots.
Plants with a height (such as 5-6′) give an estimate of the plant’s present height.
Plants that are measured in inches (such as 2.5″) are identified by their caliper, or trunk width.
Plants are typically larger when measured by caliper (inches) than when assessed by height (feet).
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.
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.
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.

How can I organically dye my hydrangeas 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.
How can I dye my hydrangeas a deep blue color?
The chemistry of the soil, not what is sprayed to the blooms, is what determines how colored hydrangea blossoms turn out to be. The color of the blossoms will increase with soil alkalinity. Some types stay pink at a neutral pH, while others begin to display exquisite lavender hues with undertones of blue. Acidic soils, usually with a pH of 5.5 or less, are ideal for blue hydrangea blooming.
Aluminum sulfate, which is readily accessible at practically any garden center, is the simplest way to acidify your soil and turn those babies blue. In the spring, as soon as the plant starts to grow, saturate the soil around your hydrangeas with a solution of 1/4 oz. aluminum sulfate in a gallon of water. Reapply in 4 weeks and again in 8 weeks because you’ll need to keep that acidity throughout the growing season.
Another, more organic way to increase soil acidity is to add organic materials like coffee grounds, egg shells, or citrus fruit peels. Simply break them up and till the soil with them. It can take a full year of doing this continuously for the changes to occur gradually, resulting in the proper acidity.
What can I do to turn my hydrangea purple?
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.
