Any landscape would benefit from hydrangeas, but they require the right watering practices to grow to their maximum potential. You would be right to assume that Hydrangeas require a lot of water given that their name literally contains the word water (hydra is Greek for “water”). But how much water do hydrangeas actually require to grow well?
Hydrangeas require more water than the majority of garden plants, and they will quickly start to wilt without it. Deeply water hydrangeas two to three times per week in the summer to ensure their success. To prevent water from evaporating as quickly as it would in the heat of the day, water your plants in the morning or the evening.
Despite the fact that hydrangeas require a lot of water, either too much or too little might be given to them. The development and blooming of hydrangeas can be stunted by both overwatering and underwatering. Long-term hydration problems may result in the death and withering of hydrangeas. Fortunately, properly watering hydrangeas isn’t that difficult. You can maintain the health and happiness of your hydrangeas with just a little care.
Do you regularly water your hydrangeas?
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 you tell if your hydrangeas need more water?
If the damage is not too severe, quick diagnosis of an overwatered Hydrangeas plant will enable you to repair it. The indicators of an overwatered hydrangea are listed below.
- Change in leaf color: If you see yellowing and browning on the plant’s leaves, you’ve probably been overwatering it. This is because a plant that is overwatered will have pulpy, swampy leaves, but a plant that is underwatered will have dry, crackly leaves.
- Root rot is an indication that your hydrangeas’ roots are rotting from overwatering, but it’s not always easy to detect. An odd fragrance may give you a hint.
- Growth that is stunted: If your plant hasn’t dried out but hasn’t gotten much longer, you should suspect overwatering.
- Dropping of leaves: If both the young and the old leaves begin to fall off but your plant hasn’t dried out, you’ve overwatered it and should act right away to prevent irreparable damage.
- Mold development: Molds are fungi that flourish in extremely moist environments or soil. Consider the likelihood of an overwatered plant if you see an increased growth of mold around your hydrangeas.
How frequently should I water my outside hydrangeas?
To help maintain moisture when planting in a container outside, choose a light-colored ceramic pot. Dark colors heat up more quickly. Make sure a drainage hole is present! At least three times every week, the hydrangea needs to be thoroughly watered. Never simply water the plant in one spot; always water it all the way around the container. The pot’s bottom ought to leak water. Never leave it submerged in water because the roots will rot away.
A hydrangea can get too much water, right?
The leaves of an overwatered hydrangea may discolor and possibly drop off too soon. Additionally, it will produce fewer and irregularly shaped buds and blooms. Additionally, a hydrangea will develop discolored, withered leaves under extreme overwatering situations.
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!
How long do hydrangeas need to be moist?
The spectacular, huge hydrangea blossoms come in a wide range of hues, including blue, red, purple, white, and pale green. You’ll be relieved to learn how simple it is to dry the blooms if you cultivate hydrangeas and wish to keep their beauty for a long time after they bloom. One type of flower that requires absolutely no work to keep is the hydrangea; it dries in about two weeks and can last for up to a year.
There are numerous techniques to preserve hydrangeas, but water-drying is the best because it keeps the flowers’ shape and color.

Is the sunlight too much for my hydrangea?
Depending on where you reside, too much sun may diminish the beauty of your hydrangea shrubs. Too much sun can cause flower petals to fall off, burn leaves, and cause withering. Giving your hydrangeas a little more water might keep them from withering if they are situated in an area where they will receive afternoon sunshine directly. Keep your hydrangeas’ soil moist, but don’t water them excessively. If your plant receives too much water, it may develop root rot or develop powdery mildew on its leaves and petals.
Can hydrangeas be overfed?
With their huge, lengthy blooms and range of colors, hydrangeas have a romantic elegance that harkens back to bygone eras. They are plants that will really enhance your landscape. Some of them are well renowned for their capacity to change color depending to the acidity levels of the soil and have become a great favorite across gardens in the U.K. Some of them will flower from summer all the way through to October.
Choosing Your Hydrangea And Where To Plant Them
There are many different hydrangea kinds, with the Bigleaf being one of the most popular. You may have heard of or seen the Mophead and Lacecap Bigleaf kinds, which are the ones that are recognized for changing color. Before you start planting, it’s important to spend some time learning about the different types and what they want in terms of growing circumstances. Other variations include the Climbing Hydrangea.
Although some will handle greater shadow, most hydrangeas like early sunlight and light shade in the afternoon. Remember that blue blooms are more likely to appear in soil with a pH below 5.5, so if you don’t want that, you may need to adjust the acidity levels in your garden. However, if blue blossoms are your heart’s desire, you might still need to add a bluing chemical even with the proper acidity to guarantee you receive the blooms you want.
Always choose a location after thoroughly preparing the soil by adding lots of compost, making sure it’s well-drained, and making sure it retains moisture. You’ll need to add a lot of well-rotted manure or peat if your land is sandy.
Caring For Your Hydrangeas
Your hydrangeas will need a lot of water during the first few years and most definitely during a dry season. If they are too dry, you’ll see them wilt. In gardens with inadequate soil, hydrangeas frequently suffer. In light of this, you might also need to mulch in the fall and feed your plants once a year in the winter or early spring. But be careful not to overfeed your plants.
Pruning Your Hydrangeas
Hydrangea pruning seems to stir some debate, but it is important to know what variety you have if you want to do it correctly. With Mopheads, you should hold off on deadheading the blooms and trimming back to the new bud until late winter or early spring. This is due to the dead blooms protecting the flower buds for the following year. On the other hand, climbing types and lacecaps can also be pruned after flowering.
Pruning back the older shoots after your hydrangea has established itself will aid in promoting new growth. Cut the entire hydrangea hardback to a height of around 15 cm above the base if you notice that it has become somewhat straggly and is producing lesser flowers. However, keep in mind that since your hydrangeas flower on a second year’s growth, it will take some time for them to do so following this type of pruning.
Can I Grow Hydrangeas In A Container?
Hydrangeas can be grown in containers, though certain kinds will do better than others and will require a bit more attention. The most important thing to keep in mind with your pot-grown hydrangea is that you’ll need to check the soil every day to make sure it stays moist and isn’t getting too dry.
They’ll need to be fed perhaps once or twice a year, but not more than that because over feeding might be harmful. Your hydrangea will likely need to be replanted every year or two because they may quickly outgrow a container.

Why are my hydrangeas fading away so rapidly?
Because of their thick, woody branches and sticky sap production, hydrangeas are sometimes among the first flowers in an arrangement to begin to appear dejected. This is because it might be difficult for hydrangeas to absorb enough moisture in a vase to cover the entire flower. But since hydrangeas are one of the few plants that can absorb moisture through their florets, completely soaking wilting blooms in water and letting them sit for a few hours to rehydrate will revive them.
If you have a few stems of cut hydrangeas that you’re not quite ready to throw away yet, it might be worth a try to revive them. The efficacy of this hack, according to Seattle-based floral designer Rizanio Reyes, “depends on when the flowers were cut and how long they’ve been in a box in cold storage post-harvest,” among other things. Freshly cut, somewhat wilted hydrangeas will probably be easier to revive than ones that have been in storage for a while (though it’s still worth a shot!). According to Reyes, “I’ve done this with some degree of success, but it’s never 100%,”
Avoid the temptation to use this method to save other popular cut flowers from withering, such as roses, peonies, or tulips. Soaking them will just hasten their decay and wilting because they lack hydrangeas’ capacity to absorb moisture through the blossoms.
