Is My Hydrangea Getting Too Much Water?

It is normal for plants to have a lower affinity to water. However for Hydrangeas ( Hydrangea macrophylla) it is a matter that they can handle in greater quantities.

However, despite its an excellent tolerance to water, it is a problem is often faced.

It’s true We can get focused on our plants and think providing them with more water will aid in their growth.

Water is vital however, you must be aware of how to use it properly to prevent the abrupt death of your Hydrangeas. The excess watering of a plant can kill the plant.

The right way to water your plants is essential to not overdo it. The methods are listed as following morning watering and at least three times per week, water only when your soil has dried, don’t water the flowers or leaves and then make sure to water the entire area around the pot.

What Are the Signs of Overwatered Hydrangeas?

There are a variety of ways to tell if you have been overwatering your Hydrangeas. The plant will certainly exhibit signs that are easily discerned with the naked eye.

By continuously and attentively monitoring your hydrangea you’ll be able to tell if it’s acting normally or not.

Here are the most common signs of an overwatering problem:

Root Rot

It isn’t as obvious as the other signs because the roots are concealed beneath the soil. It is difficult to tell if roots are decaying until you notice other signs visible above ground.

However, the primary hydrangea component that is affected when you water too much is the root. Root Rot is a frequent result. Roots that are drowning are brown and are slimy when they are touched. They also have a horrible smell.

Browning and Wilting of Leaves

As a result of the root rot issue are change in color and shape of leaves. Particularly, plants that have been overwatered tend to produce brown leaves that become soft when they are touched. This is due to the excessive amount of water within the plant cells.

The leaves’ browning is evident on the edges. Do not confuse this with the browning that is caused by the underwatering. The leaves that are underwatered are dry, whereas the leaves that have been overwatered are soft and soft and pulpy.

Yellowing of Leaves

Another consequence of excessive watering is the leaves of hydrangea becoming yellow. Chlorotic leaves develop because of the absence of the essential nutrients iron that plants can get for their consumption.

There are many factors that can cause this issue, but one reason is that damage to roots.

We are all aware that water-logged Hydrangeas can develop root rot , which can cause the most serious harm to the root.

This hinders the transfer in nutrients and minerals from soil to other plant parts, including the leaves.

Stunted Growth

A typical indoor hydrangea could reach 2 feet (60 centimeters). If your plant isn’t getting close to that height and has not produced healthy leaves, then excessive watering could be the reason.

A lot of water can cause root rot as well as the growth of molds. Both hinder the development as well as the health of your Hydrangea.

Dropping of Leaves

A sign that the hydrangea has been overwatered is if you observe the loss of its leaves.

In this instance you will notice two the new leaflets are falling from the stems.

The excess water causes plant cells to explode and die, causing the petioles to lose power.

In the process, the leaves begin to fall from the stem. If you notice the leaves of your hydrangea appear weak and limp It’s likely that it has been overwatered.

Presence of Molds

A humid environment is a prime location for molds to grow. If you let your hydrangea plant to endure exposure to moisture, it can promote the development of spores.

A good example is the Botrytis cinereawhich causes botrytis blight which infects the delicate flowers of your Hydrangea.

The damp conditions encourage pathogen activity in soil, which causes fungal growth in one area that then can spread to other parts.

How to Save Overwatered Hydrangea?

You’re likely to be a bit worried after you’ve noticed one or two symptoms in your beloved Hydrangea.

If you’re worried that overwatering could cause dying your plants, it is better to be optimistic because there are methods to keep them alive.

Here are the step-by-step steps to follow:

Repot the Plant

The first step is to determine if you must do is determine how damaged the roots are.

  • Take the plant carefully out from the pot. Be aware that plants with decaying roots usually have soft bases, therefore be extremely cautious when handling them.
  • Remove any soil that is soiled so that the root system is exposed.
  • Take a look at the roots and search for the ones that are rotten. Prune them carefully out of the plant.
  • Let the roots dry out a bit by placing it in a container before planting it up again.
  • Make sure to use fresh soil with adequate drainage and a container that is of the correct size and has drainage holes.
  • Plant your hydrangea in the new pot, and fill in the gaps with soil that is just right.
  • Re-water the newly repotted hydrangea until it’s completely submerged.
  • Make sure to drain the soil several hours prior to when you put it in.

Relocate the Plant

To prevent the young hydrangea leaves from dying it is important to stay out of direct contact with sunlight.

If your indoor plant was placed close to your window, where it gets direct sunlight, put it in a shaded area.

  • Find a spot in your home that is not in direct sunlight, but isn’t too dark.
  • You can add shading to the hydrangea by using larger leafy plants or curtains.

Be aware that plants with excessive watering are unable to transport water due to damaged roots.

A lot of sun exposure results in more transpiration of the leaves. This can lead to the drying out of the plant itself.

Remove Damaged Leaves

As much as we would like to preserve the hydrangea’s leaves it is necessary cut them back.

Brown leaves no longer function because they’re made of nothing but dead cells.

They can affect the overall appearance of your plant, and could potentially spread disease to younger leaves.

  • Cut the leaves carefully with pruning shears or scissors to create more space for new leaves to grow.
  • Cut off the upper leaves in proportion to the roots you cut below. This will help sustain the growth of the preceding areas of the plant.

Treat the soil with fungicide

As we mentioned the molds thrive in moist environments. The soil around your hydrangea that has been overwatered is now a perfect habitat for fungi to flourish. It is recommended to eliminate them using fungicides in order to eliminate the pathogens.

New soil that is enriched with amendments instead of the previous one is preferred. It will not only reduce the possibility of transmission of pathogens and also offer an entirely new source of nutrients to the plants.

How to Water Hydrangea

Since overwatering is an everyday occurrence It is recommended to provide an extensive guide to how to correctly water your Hydrangea plant.

Remember that the main point in this case is control. Your plant may require either less water or more based on a variety of factors.

Water in the Morning

A plan plays an important part in creating a successful routine for watering. It is best to water your garden in the morning since the heat helps to evaporate any excess water all day.

It also helps supply water to plants which are extremely important during the summer months when temperatures are hot.

In general, plants transpire more when temperatures are higher. This implies that water is utilized more in plants at daytime, but less in the evening.

Water at Least Three Times a Week

Because hydrangea is an indoor plant that is large and requires a lot of water. The optimal frequency is at least three times per week.

However this frequency isn’t set in stone. It is necessary to alter this as the temperature gets warmer or colder.

It is recommended to use deep watering. Be sure that the water gets to the base of the pot, and then drains completely in a quicker rate.

Water When the Soil Is Dry

While we’ve talked about a regular frequency of watering, you should always take into consideration the condition of your soil. Are you sure that it is dry enough to allow water to flow again? Check it out first.

Make sure you press your finger into the soil, at least 2 inches deep. Check if the soil is dry. If it is, you can add water to it. In case it’s damp, then leave it as is and keep it dry until the water is dry.

Do Not Water the Leaves and the Flowers

Simply go straight to the roots. The roots’ task is to carry these water molecules to different areas of the plant’s body. Be careful not to splash on the leaves and flowers.

In addition, adding more water to the plant parts can encourage fungi to establish. We don’t want that to happen, and lead to diseases in our hydrangeas.

Water All the Way Around the Pot

Be sure to cover the soil by making sure to water it all within the pot. Do not just focus on only one area.

This will help disperse the moisture over the soil, and to hydrate all root systems of plants.

A uniform distribution of water can help the roots to grow evenly.

Roots tend to follow the direction of where water is situated. If one area is more water-rich than the other, the roots will move to the area with more water.

When to Water After Transplanting Hydrangea?

Transplanting can be a stressful procedure for your hydrangea since the roots are being disturbed.

It’s common for it to suffer from the condition known as transplant shock. It is essential to drink water to ensure it is able to survive following transplantation.

Water Immediately After Transplanting

Soak the soil thoroughly by with the water hose. Be aware that hydrangeas transplanted recently aren’t yet established in their root system yet , and are unable to get the water in the soil.

A good supply of water will stop the roots from exerting a lot of effort to find it. Make sure that the water drains completely from the pot and does not get trapped inside.

Water Religiously

Based on the timetable you decide to set, you will need to water your newly transplanted hydrangea in a regular interval. If not, the plant is likely to die because of the dehydration.

It is essential to add more water in the beginning, until roots are established fully in the new medium.

It is evident that the plant has been able to harden off and is not as droopy. It could take a few days or weeks to see it occur.

Common Mistakes in Watering Hydrangea

To avoid making the same mistakes that others have made I’ve listed below the most common mistakes made when watering the hydrangea plant indoors.

Take a look at certain practices are routinely practiced without realizing it’s harmful to the plants.

Watering During the Night

It is possible that you were busy getting out of the house early in the morning, and now you’re not able to water the plant.

The evening came around and you realize that you need to water your hydrangea , and you did. It’s a blessing if your hydrangea is still flourishing.

The indoor plants like the hydrangea need to be watered each morning. They require water throughout the day, especially in the summer months, when it is warmer than during the evenings.

When you are watering them at late at night, then the likelihood is to let the water remain in the soil for a bit longer.

Have you noticed that once you get up and the soil is damp? If you keep doing this the plant will eventually be affected by root rot, especially as the colder nights arrive.

Watering Without Consistent Schedule

Regularly watering the plant helps it receive enough water at the time that it really needs it. The intervals allow the soil to cool off completely before it receives water again.

If you don’t follow a regular watering schedule it is possible that you water too early or too late.

Both can be harmful to Hydrangea because they can result in dehydration or overhydration which can lead to death. It is essential to know when you should water again.

Watering Even During Wet Seasons

Naturally, your plant won’t require more water during the dry or cold winter months.

The water molecules won’t evaporate as quickly when the air is moist or saturated. This means that your plant will store the water for a longer time.

If you are adding more water in this period it will exceed the amount your plant consumes. The waterlogging will follow.

Watering Without Checking the Soil Moisture

The sight of the soil drying on the surface could make us want to immediately water the plant.

But, it could be misleading because often the soil remains wet even as you sink your fingers two inches further.

If you only water when the topsoil isn’t dry the roots are at risk of developing root rot since the soil beneath hasn’t completely dried out.

Watering the Leaves and the Flowers

Although this might seem like an ideal way to refresh your hydrangea’s plant however, it isn’t likely to benefit.

It’s just an environment that is moist, which is ideal for fungi to grow on the flowers and leaves.

This isn’t a good idea as it could trigger the spread of unwelcome diseases.

For indoor plants that are less exposed to sunlight, the water will be slower to evaporate.

The leaves that have been damp for too long may be prone to decay.

Watering Without Good Drainage

Although you’re cautious about the amount of water you’re using to water your hydrangea, with no drainage system, excessive watering is still a concern. The soil that drains poorly is damp enough to allow roots to sink.

A drained container that isn’t properly drained could also cause harm. It happens when plants are placed in pots that don’t have drainage holes or in a pot that is too big to hold additional water.

Watering When Water Isn’t What It Needs

It’s not difficult to determine that the plant requires more water when we observe it becoming wilted.

However, it is important to be aware of other elements that affect the health of a plant. The hydrangea requires additional elements, such as sun and nutrients.

Water isn’t always the answer. If you don’t recognize the root cause of the plant’s problem the addition of water could cause more harm than good.

It is important to be able to make an informed decision on this in order to avoid giving incorrect treatment. (Source: Oregon State University Extension Service)
