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.
Exactly why isn’t my hydrangea plant thriving?
Nearly nothing is as showy as a hydrangea (Hydrangea spp.) in full bloom as far as blooming shrubs go. The bushes’ enormous clusters of pink, white, or baby blue blooms and thick foliage make them highly desired. Hydrangeas will flourish, thrive, and last if they are given the proper care. Failure to thrive or even death of hydrangeas is typically caused by one or more unfavorable environmental or cultural factors, many of which may be remedied.
According to Missouri Botanical Garden, shrubs are generally hardy in U.S. Department of Agriculture plant hardiness zones 3 through 9, depending on the species.
Tip
Problems with hydrangeas, such their inability to grow or bloom, may be caused by unfavorable weather conditions like frost or too much sun, or they may not be receiving enough water. They could potentially be harmed by ineffective pruning.
How do I get my hydrangeas to grow well?
Smooth hydrangeas (Hydrangea arborescens), which get their name from the texture of their huge leaves, are more well-known for their massive, spherical, white flower heads. The most popular type, “Annabelle” (also known as Snowball Bush), was identified as coming from Anna, Illinois, by a horticultural expert in the 1960s. The ‘Annabelle’ hydrangea displays large, pure-white blooms that gradually turn green. A more recent cultivar, Invincibelle Spirit, blooms pink rather than the usual white. The smooth hydrangea, which is native to parts of North America, starts blooming in late June and keeps periodically flowering all summer long. In zones 4 through 9, it thrives in sunny or slightly shaded environments.
How to Get More Smooth Hydrangea Flowers:
- If the soil is damp, grow smooth hydrangeas in full sunlight. (Spots that occasionally dry out benefit from partial shade.)
- In droughts, especially in the sweltering summer, water them.
- soil amendment using organic matter (such as compost).
- In the early spring, soon as new growth begins to appear, trim back stems.
How can you assist a hydrangea in need?
A hydrangea’s roots can be burned if too much fertilizer is used, which will likely result in the plant dying, turning brown, and drooping.
As such, hydrangeas are not heavy feeders and do not require annual feeding in the same manner as roses do, and doing so can actually be detrimental.
Hydrangeas frequently develop and flower to their full potential if they are planted in healthy soil or the soil has been modified with compost prior to planting.
The hydrangea should flourish if a 1-inch-thick layer of mulch is applied around it to assist retain moisture and supply nutrients to the soil (compost and leaf mould are ideal options).
Only in the following circumstances should fertilizer be used:
- Planting the hydrangea in sandy soil (which is nutrient poor).
- The hydrangea is in a pot or other container where the roots have used up all the nutrients in the soil.
In these two situations, it is recommended to use an all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK) that is applied once in the spring and is generally well-balanced.
The roots of your hydrangea can be burned by well-rotted manure, especially if it is added to the soil after planting. However, if the manure is made from poultry manure, it may contain a lot of nitrogen.
To prevent issues, I advise putting compost to the soil as a soil amendment (fresh manure is particularly harmful, always allow it to rot for a year or so before using manure on your garden).
If your hydrangea is exhibiting indications of stress as a result of being recently planted in soil that has been altered with manure, move it to a location with soil and compost, and it should recover.
Reduce the amount of fertilizer used and remove any discolored leaves or blossoms. To assist the hydrangea recover, thoroughly water it in an effort to dilute the soil’s water-soluble nitrogen.
Key Takeaways:
- Most frequently, hydrangea deaths are caused by the soil’s lack of moisture. Because they need their soil to be continually moist, hydrangeas will droop or even die in a dry environment.
- Drought, transplant shock, frost damage, and too much sun can all cause hydrangeas to perish.
- If the pot base doesn’t have drainage holes, potted hydrangeas may succumb to root rot. Small containers may dry out too rapidly and limit root expansion.
- Water hydrangeas liberally, cover them with compost mulch, and keep them out of the sun and wind to help them recover. To encourage healthy growth, remove any growth that has been sunburned or damaged by frost.
Why do my hydrangeas seem to be growing so slowly?
Hydrangeas are thirsty plants in all of their varieties. These plants need a lot of water, especially when they are just starting out in your garden or plant container.
One of the most frequent causes of this issue with hydrangeas is a lack of water, which can result in stunted growth in your plant. As most people are unaware of how much water these plants require to flourish and grow properly, underwatering your hydrangeas is simple to undertake.
If your hydrangeas’ soil dries out in between waterings, this could interfere with the growth of your plant and prevent your hydrangeas from blooming. Hydrangeas like their soil to be continually moist.
If you have hydrangeas, you should water them according to their type and the environment they are kept in. If you have a bigleaf kind of hydrangea and live in a dry, hot area, for instance, you will need to water your hydrangea every other day to keep it from drying out.
To grow in your care, hydrangeas require at least two inches of water every week. Therefore, you will need to water your hydrangeas more frequently if you leave them outside and there isn’t much rain.
A rain gauge can help you monitor the amount of rain your Hydrangeas are receiving and how much additional watering is necessary.

Can hydrangeas benefit from 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.
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.
What is a hydrangea’s natural fertilizer?
For the development of their flowers, plants require phosphorus, magnesium, and other trace minerals like iron or calcium. Both household compost and animal dung are beneficial fertilizers for hydrangeas to add to the soil beneath the plant. To provide the roots with an excellent source of potassium, phosphorus, and magnesium as well as to foster the acidic environment that hydrangeas enjoy, apply a teaspoon of vinegar mixed with a quart of water.
Are hydrangea plants suited for Epsom salts?
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.
