How To Keep Hydrangea Plants Alive

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.

My hydrangea is fading; why?

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 can a dead hydrangea be revived?

Greek words “hydor,” which means “water,” and “angos,” which means jar or vessel, combine to form the term “hydrangea.” Translation: a barrel of water! These lovely flowers that resemble pom poms require water to survive, and if they don’t get it, they wilt.

The woody stem of hydrangeas can make it challenging for the flower to obtain the water it requires. A small slice cut into the stem and an angled trim with a sharp knife help the plant absorb more water.

I used to use scissors to trim the ends of my flowers, but I’ve since moved to using a sharp knife on the advice of my friends at Byland’s. Apparently, using scissors causes the stems to be pinched, harming them and limiting their ability to absorb water.

While they were beautiful to look at when we originally built the floral arrangement for our Mother’s Day Frache Table, it didn’t take long for them to start to look very melancholy. I was able to keep them from being thrown away thanks to this simple approach, and the flowers still looked new and fresh!

Keep in mind that hydrangeas might wilt to a certain extent after which they cannot recover. The good news is that this hack is really easy to use and doesn’t call for anything complicated, so why not give it a shot?

Directions:

  • A kettle or pot of water should be heated up and then left to cool gradually. It ought to be really hot right now. Fill the vase with water.
  • Cut the ends of the hydrangeas at a 45-degree angle with the sharp knife after setting them on the cutting board. Then, on the newly trimmed stem, make a tiny vertical slit running up the middle.

How are potted hydrangeas cared for?

If you’ve ever received a hydrangea in a foil-wrapped pot, you likely loved it for a few of weeks before seeing it sadly wilt. You might conclude from it that hydrangeas are poor container plants.

Most hydrangeas that are given in pots as gifts do poorly because they are kept indoors for too long. Others perish because they were grown in a greenhouse and are not cold hardy in your region of the country, even if they are planted outside.

However, hydrangeas can make wonderful potted plants if you choose wisely. What you should know is as follows.

Potted Hydrangea

You can utilize hydrangeas in containers in your garden on stands, decks, or patios. This plant looks classy perched atop an antique column.

  • Choose a location for the hydrangeas first. You may move them around, which is one of the benefits of growing them in pots. This also makes it simpler to provide hydrangeas with the ideal growing circumstances because many of them like morning sun and afternoon shade. Additionally, you can arrange them to beautify a patio or other area for a celebration or special event.
  • If your pots won’t stay in the same spot all the time, search for containers with wheels on the bottom or think about durable, rolling plant stands. Don’t forget that after adding dirt and plants, containers can become rather heavy, and soaking them can make them even heavier.
  • For your hydrangea, pick a large container with a diameter of at least 18 to 20 inches. The plant commonly wilts in small pots like the one your gift hydrangea arrived in since they typically dry out too quickly. Drill drainage holes into the bottom of your container if there aren’t any already. Rotting can result from water that accumulates around the roots.
  • Next, pick a variety that is advised for your area. (This is a general guideline for growing any plant well.) To choose the best types for your yard, read plant tags or conduct online study. Some hydrangea varieties can grow in USDA zones 3 and 9, while the majority are hardy in zones 4 to 8.
  • Although using miniature hydrangeas in pots isn’t required, you might wish to if you have a small yard. Not only do hydrangeas grow tall, but they also become bushy. If not, prepare to prune your plants as they develop. Be careful when conducting your research; see if your variety blooms on new or old wood. You’ll lose the flowers for the following year if you prune at the incorrect time of year.
  • Use high-quality potting soil that contains organic materials rather than regular garden soil. If you want the hydrangea to continue growing, don’t plant it higher or deeper than it was in the pot it came in. Make sure there is space below the pot’s rim so you can water.
  • To get rid of air pockets, gently compact the dirt close to the roots.
  • Water your hydrangea well whenever the top inch or so of the potting soil feels dry. But being underwater is preferable to being overwatered. When they are thirsty, hydrangeas may wilt to let you know. However, this can stress them out, so check them every other day or so. You’ll eventually get a sense for how frequently to water. In times of drought or extreme heat, you might need to increase your watering.
  • Although hydrangeas don’t require a lot of fertilizer, you can feed your plants once or twice a year with a commercially available composted manure, a 10-10-10 granular fertilizer, or a slow-release balanced fertilizer. If you reside in a warm environment, wait until after July or August to fertilize. Gardeners in the north can get away with applying fertilizer just once, in June or July. Feeding hydrangeas later, when they should be starting to go dormant for the winter, promotes fragile, fresh growth.
  • If your plant already appears to be ill or unhealthy, don’t fertilize it—you’ll just increase its stress. Try to solve the issue instead.

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!

Do I need to remove the Brown hydrangea leaves?

If newly emerging hydrangea leaves or flower buds are exposed to a late-spring frost or chilly winds, they will turn brown. A unexpected cold spell can harm the newly emerging buds and leaves, which are exceptionally delicate and susceptible to injury. This can cause the buds to turn brown and wither away.

Naturally, hydrangeas grow in protected regions under trees that block chilly winds and produce a more stable microclimate that allows the young flowers to open up without facing a serious risk of frost.

Hydrangeas’ newly formed buds and leaves can become mushy and their leaves can turn brown when they sustain frost damage.

Since it is more exposed to the environment, the outermost growth is typically the one that suffers from the worst damage.

Sadly, the harmed flower buds are therefore unable to bloom, and the freshly growing growth is probably not going to recover.

Frost damage to hydrangea flower buds and foliage is more common in exposed areas, so plant or move your hydrangea to a more protected area of the garden, close to your house, or close to some other plants and hedges.

Particularly hedgerows are great wind breakers since they shield your hydrangea from the elements and might lessen the effects of frost.

There isn’t much you can do to save flower buds or younger leaves after they turn brown. As a result, prune back to healthy growth any growth that has been harmed by the frost.

In contrast to the flower buds on the plant’s outermost part, which are naturally less protected, hydrangeas frequently have growing flower buds farther down each branch. These flower buds typically survive a frost.

This implies that your hydrangea can still bloom, but much later and with fewer flowers emerging. With a little patience, you should still be able to enjoy some lovely blooms throughout the Summer.
