Indeed, seeing your beloved Hydrangea plant struggling is disheartening. Mainly because you probably are the reason for this.

Yes, if you do not care for the plant properly, the rotting root will appear on your Hydrangea plant. The cause your plant is sick right now is your stupid mistake! But you should patch this! But hey!

We explained your mistakes and your solutions to motivate you.

1. Over or Underwatering

Plants will go a long way if the right amount of water is given. Otherwise, they’re going to send you symptoms of root rot.

So, how much water do plants need from Hydrangea?

Ok, plants from Hydrangea require a lot of irrigation. At least 3 days a week, they must be watered.

If you live in a dry environment, you will need to water the plant more. Or where the average temperature in winter is between 28-39 degrees Celsius. And in summer, 69-78 degrees. Moreover, though, every morning, we mean watering the garden.

This way, you won’t be overwatering the plant. Also, if you didn’t know, the plant’s roots can rot if it’s overwatered. This situation results in purple leaves. Plus, checking the soil before watering again is vital. Because if your drainage system is lousy, watering regularly increases the chance of having purple leaves. 


Don’t fret if you’ve been messing up while the plant is watering! Think about how the plant should be handled now instead!

First of all, the soil must be tested to see whether you are under the plant or overwatered. You sprayed the plant too much if the soil is pretty wet. And it couldn’t digest anything.

Lift the plant up and place it in a particular jar or container. At least 3-4 draining holes should be in the pot. Be a little careful after replanting. As it is essential to drain the bath.

Once the water is drained, measure the surface. Test the soil. Using a humidity meter to determine whether or not the soil is damp. You will begin watering again if you do. Now, it’s scorched when you hit the ground. You didn’t give sufficient water, that implies. And some people pray for the lousy vine!

That’s why you can easily supply your Hydrangea with water. Water before you see drainage holes come out of the pot. Then encourage the Hydrangea plant through its roots to absorb water. And this is it! Hopefully, soon it will improve!

2. Insufficient Lighting & Wrong Temperature

Faulty lighting and temperature can actually contribute to rooting in your vine. These bad living conditions ruin your facility.

Now, plants from Hydrangea grow in luminous areas. The average thumb rule is 6 hours a day of the sun. However, in the south, there could only be 3 hours of sunshine. It must be put under an LED light for at least 8 hours. But without the help of light, this plant cannot produce fruit. And that lets the root rot gradually.

Now it is also expected to check the temperature. At least 65-70 degrees of Fahrenheit should be given throughout the day. Even at night time 55-60 degrees.

The easiest way is to provide illumination by the temperature level. There is no appreciation of both abundance or lack of illumination and temperature. Due to the excessive heat rotting the roots. The plant becomes hungry while there are too little light and temperature. The plant thus shows the rotting roots.


If you detect that it’s due to insufficient lighting and temperature over the Hydrangea plant to a place where there is enough sunlight. Or get yourself a full spectrum LED grow light. Before placing the plant under the light, check the temperature of that spot. If the temperature matches with the ideal one, you’re all good!

3. Over or Under Fertilization

Now, lack of nutrients is the first reason why the plant will have root rot. 

A Hydrangea plant prefers soil that’s rich in phosphorus, nitrogen, and potassium. Therefore, if there’s a deficiency in one of the nutrients, the plant won’t get the preferred pH level of  6-7. And this will lead to the purple leaves. 

Now, even though we’ve mentioned three nutrients-

The root rot mostly appears due to phosphorus deficiency. Because this nutrient is needed for producing energy, nucleic acids, and sugars. Simply put, for food! 

Another reason is over-fertilization.  Growing can decrease by fertilization, and plants become fragile and exposed to diseases and pests. It may also eventually cause the plant to die.

Overfertilization signs include stunted growth, dried or burnt leaves’ margins, wilting breakdown, or plants’ death. The most significant risk to fertilizers is “burning.”

High levels of different salts are present in fertilizers, and humidity from their sources can be drawn out in a procedure called reverse osmosis.

When salt’s surface content is more important than the plant’s soil, and the plant is at risk of chemical burning and dehydration, reverse osmosis will occur.

Just follow the instructions of the usage of fertilizations according to your plant.


So the questions here should be how you can save your plants from over or faulty fertilization? 

The solution for this problem is straightforward, actually. First, always try to use organic fertilization. As it comes from nature, it will be nature friendly.  

If you have to use chemical fertilizers, you should be careful about how much and where you are using it and how much of it you are using. Always put it in a few distances from the plant.  In this way, the plant won’t be affected by the fertilizers directly.

4. Infestation of Insects

Insects may probably be a cause for these violet leaves. It is well understood that the juice has been absorbed by the leaf tissue. This leads to the loss of chlorophyll from a plant. Now, much of the Hydrangea plants are spider mites, aphids, and thrips. Since Hydrangea likes these three.


It is relatively easy to handle! And it uses a pesticide dependent on plants. You won’t hurt the plant in this way. But the insects can be removed. In the infected areas, we recommend rubbing with alcohol.

You can even apply for Monterey LG6135 Garden Insect Spray. These insecticides will definitely be helpful to get rid of the annoying insects!
