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 encourage the growth of my hydrangeas?
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.
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.
Why aren’t my hydrangeas growing more quickly?
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 a bushier hydrangea?
With all varieties of hydrangea, it pays to grow a robust, bushy plant before you consider flowers. The first few years following planting are crucial for hydrangea trimming because they lay the groundwork for future years.
It is best to pinch or trim your plant when it is young in order to develop a robust, well-branched plant. A plant will produce twice as many branches and ultimately more flowers if the growth tip is removed.
If the plant was lanky when you bought it, hard-shear it back by a third to a half of its original size. Pinch the branch tips to remove only the growing tip once it has added one or two inches of growth. This point regulates branching. The buds beneath it will develop into two or more stems when it is removed. Pinch the tip out once again when these young branches have grown an inch or two.
As you take care of your garden, you can keep doing this all through the first growing season. This method produces a well-branched, full-bodied plant that will have more flowers in coming years, even if you may lose one year of bloom in the process.
Repeat the pinching procedure for the second growing season (or lightly shear). Stop trimming and pinching so that the flower buds can form.
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.
How come my hydrangeas are so tiny?
When you grow hydrangeas, you anticipate your plants to produce massive amounts of eye-catching blossoms. After all, hydrangeas are renowned for doing just that. However, Hydrangeas don’t always produce the huge blooms you see at the garden center once you bring them home. The blossoms can occasionally be smaller than you anticipate.
What then results in little Hydrangea flowers? The most frequent reason is improper treatment. Hydrangea flowers can be stunted by too much water, sunlight, or fertilizer, which results in tiny blooms. To make sure that Hydrangeas are taken care of properly, try making the changes listed above. When you get that right, they’ll start to produce the big blossoms you want.
There is a Goldilocks complex with hydrangeas. For them to be content, the ideal combination of sunlight, water, and fertilizer is required. neither too little nor too much. Determine if one of these is the issue by inspecting your hydrangeas. You might only have a variety with fewer blooms if you are certain that adequate maintenance is not the problem but your hydrangeas are still not showy enough.

Does using coffee grounds on hydrangeas work?
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 should a hydrangea be cared for?
Both the method and the fertilizer used while fertilizing hydrangeas are crucial. Burning from fertilizer can happen when too much is used. The first indication of over fertilization is scorched-looking leaves. Fast-release fertilizer needs to be lightly applied to hydrangeas in March, May, and July.
Make sure to distribute it along the branches’ drip line rather than their base. Water wisely. Remember to lightly cover the fertilizer with soil to activate it if it is a slow-release variety. Add a small amount of liquid iron every two years to maintain the leaves’ vibrant green color.
Without noting the use of modest amounts of sulfur or lime when fertilizing to modify hydrangea color, a discussion of how to fertilize hydrangeas would be incomplete. Sulfur-treated hydrangeas can stay blue or turn that color. Pink is produced by lime, and it takes time for any color to change. Please be aware that white hydrangeas won’t turn color.
Hydrangea maintenance and feeding should be done properly to ensure lush foliage and beautiful blooms.
