Although the hydrangea’s leaves and flowers seem delicate, little careful care is actually needed for them. Everything you need to know about caring for hydrangeas is provided in these recommendations.
- Over the course of the growing season, water at a rate of 1 inch per week. To promote root growth, deeply water three times each week. All varieties of hydrangeas benefit from constant moisture, but bigleaf and smooth hydrangeas need more water. To water thoroughly while keeping moisture off the flowers and leaves, use a soaker hose. Hydrangeas won’t wilt as much if they are watered early in the day on hot days.
- To keep the soil around your hydrangeas cool and moist, add mulch. Over time, an organic mulch decomposes, supplying nutrients and enhancing soil texture.
- Apply fertilizer according to the type of hydrangeas you have. Every variety has varied requirements and will profit from applying fertilizer at various times. A soil test is the most effective tool for determining your fertility requirements.
- In March, May, and June, bigleaf hydrangeas require numerous mild fertilizer applications.
- Two applications in April and June work best for oakleaf and panicle hydrangeas.
- The only time smooth hydrangea plants require fertilizing is in the late winter.
- By selecting cultivars with resistant characteristics, you can avoid pests and diseases. Hydrangeas can have leaf spots, bight, wilt, and powdery mildew. Although they are uncommon on hydrangeas, pests might arise when the plants are under stress. Aphids, leaf tiers, and red spider mites are examples of potential pests. Your best line of defense is to properly care for hydrangeas.
How can I improve the blooming of my hydrangeas?
According to Enfield, certain varieties of hydrangeas develop larger blooms on their own and as a result require varying amounts of water and sunlight. It’s crucial to understand what kind of hydrangea you’re cultivating, she advises. “Bigleaf (H. macrophylla), which includes ever-blooming varieties, Smooth (H. arborescens), Panicle (H. paniculata), and Oakleaf are the four main classifications of hydrangeas (H. quercifolia). To determine what kind of hydrangea you have and how to care for it, look at the plant tags.”
Should I remove the brown blooms on my hydrangea?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
What benefits can Epsom salt provide hydrangeas?
A: We just moved a number of hydrangeas, and we are happy to report that they appear to be flourishing. We’re wondering what the best food is for them, as well as when and how often to feed them. Epsom salts, according to someone, might be beneficial for hydrangeas. Is it accurate, and what ratio would be ideal?
A: Spring and the beginning of summer are the best times to fertilize hydrangea bushes. A slow-release fertilizer treatment at the start of the season is advised by certain producers. A good compost covering will have a comparable impact.
While a generally balanced fertilizer with all the numbers the same (10-10-10) is acceptable, it should be noted that a fertilizer with a larger phosphorus content (the middle number) may promote more flowers. This costs money. A higher phosphorus content in the soil can raise its alkalinity, which may result in pink blooms rather than blue ones. This is because phosphorus changes how well plants absorb aluminum (which is best at a pH of 5 to 5.8).
The pH of the soil has an impact on pink and blue hydrangea macrophylla. Blue flowers do best with a pH below 6, whereas pink blooms thrive with a pH above 6.
Magnesium levels in the soil are increased by adding Epsom salts to your plant. Some plants require a lot of food. I’ve applied Epsom salts on potted aromatic geraniums firsthand.
Does it assist? There is disagreement among experts. Some claim that the extra magnesium and sulfate replenish the soil’s depleted reserves. Some claim that any impact would be small. Therefore, the answer is definitely maybe.
Instead, I advise finding the soil’s pH, checking for deficiencies, fixing them, and then, if you really want to, adjusting it by adding composted pine needles, oak leaves, or coffee grounds to increase acidity and lower pH, or wood ash or lime to increase alkalinity and raise pH.
There are fertilizer blends made especially for hydrangeas, Organic Espoma products like Soil Acidifier or Garden Lime, and fertilizers like Bonide or Bailey’s Blue or Pink.
I have an arborvitae border. The top foliage on two of them has turned brown due to a bagworm infestation. They were doused in triazicide by me. Any more recommendations for therapy? Should I get rid of the dead vegetation?
A: Caterpillars that are dark brown are bagworms. They make little, silky pouches that they put on to move around, consume our plants, and spend the night in them. In the pouches, they deposit eggs as well.
Bagworms are killed by the long-acting, broad-spectrum insecticide triazicide. The product does, however, effectively kill at least 260 different insects upon contact, and not all of them are harmful, as stated on the label.
If you find bagworms on the plant and it is not a gigantic plant, cut the damaged stems and the bagworms off the plant and throw them away. Spray your trees with permethrin, spinosad, or Btk (Bacillus thuringiensis kurstaki) if the larvae are still young (they emerge in late May).
You should definitely treat the entire group if the afflicted plants are a part of a row or cluster that is greater in size. Follow all instructions and make sure the product is effective against bagworms before using any commercial products. Find any remaining bags in the fall or winter, remove them, and burn them because they contain the eggs that will hatch the next spring.
Dogwood leaves are beginning to turn color, as a little breeze sends a few yellow leaves tumbling to the ground. Fall has officially arrived. Even though the days are getting shorter, it’s still warm outside, so don’t go inside just yet.
Stop pruning, start planting, and finish the winterizing tasks—clearing gutters, repairing any damaged windows, caulking insect entry points—before it gets too cold.
The potted plants that didn’t get enough water are being revived by me. Some are unquestionably dead, while others ought should survive till spring. I may just weed-whip them down and deal with what’s left in the spring because the weeds are also out of control.
- Planting:

Do hydrangeas like shade or the sun?
With the ideal balance of morning sun and afternoon shade, hydrangeas flourish. Even the sun-loving Hydrangea paniculata will thrive in some shade. Some hydrangea cultivars may survive complete shadow, though.
The oakleaf hydrangea, also known as hydrangea quercifolia, is a substantial species of hydrangea that may reach heights of up to eight feet. In a shade garden, this big bush makes a beautiful backdrop. The height will provide excellent midsummer seclusion. Oakleaf hydrangeas are summer bloomers with mostly white blooms, elegant oakleaf-shaped leaves, and lovely peeling bark.
Hydrangea anomala ssp. petiolaris is another choice for full shade. This climbing species, which has lacy, white blossoms in the summer, can reach a height of 50 feet if it is given adequate support. The foliage is a rich shade of green and would look wonderful growing up a tree trunk or covering the face of a building. It would also look lovely covering the roof of a garden shed.
Full shade cultivars require the same upkeep as partial shade. In the deeper shade, it will be especially crucial to keep the plants free of leaf litter and with excellent airflow. Water your plant once a week after it has become established. Keep a watch on the leaves, and if you notice any drooping, especially during the hot summer months, water them right away. The importance of this increases in hotter regions.
These leaves’ unique shape would be a lovely complement to Hosta leaves. The white blossoms would contrast nicely with the lighter hues of your shady blooms and provide some brilliant brightness to your shaded locations.
Shade Varieties
There are a few different hydrangea cultivars that thrive in the shade. Some types can even thrive in zones 3 (which doesn’t warm up until later in the spring), which is one of the coldest growing regions. Let’s examine some of the best shade selections!
Hydrangea quercifolia ‘Snow queen’
The movie “Snow queen” is stunning. The flowers are stunning, as they are with all hydrangeas. These rose blush-colored blossoms appear in the middle of summer. The foliage of this plant is my favorite component. The leaves begin the season in a very deep green, gradually changing to a deep reddish bronze color, and finally finishing in that shade, offering a stunning splash of color to your fall landscape.
Hydrangea quercifolia ‘Alice’
With a height ranging between 12 and 15 feet, this Oakleaf Hydrangea is one among the biggest. In the summer, this plant blooms with incredibly deep cream-colored flowers. A woodland garden would be a truly lovely place for “Alice.” This cultivar would look especially beautiful if it were grown as a bordering hedge.
Hydrangea arborescens ‘Annabelle’
‘Annabelle’ enjoys partial shade and has some of the largest flowers in the hydrangea family (12 inches wide!). These enormous blossoms can be supported all season long by the sturdy stalks. This shrub can grow up to five feet tall and five feet broad, so give it plenty of area to expand. These enormous, all-white blossoms bloom for a long time.
In a mass planting, as a specimen shrub, or as a foundation planting, “Annabelle” would look lovely. These bushes should still be included in your cutting garden. Imagine a bunch of flowers that large! Wow!

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.
