How to Save Your Overwatered Petunias

In this article, we’re going to discuss how to revive your petunia if you’ve overwatered it.

Petunias are often neglected when they are considered indoor plants, and their owners usually prefer to water the plants in the same manner as they would if they was outside in the yard.

There are subtle differences between indoor and outdoor maintenance, and you’ll also have to be able to recognize signs of excessive watering.

It is possible to revive a petunia that has been overwatered when you act swiftly. Take the plant out of its pot and place it on a piece of paper for a couple of weeks until its rootball is dry. Make sure it is not exposed to the direct light while this process is happening. Repot it into potting soil that is fresh following that and don’t keep it watered for three days.

If you realize that you’ve overwatered your petunia, we’ll examine ways to bring it back.

Of course how can you avoid repeating the same error at a later time.

Underwatering symptoms versus overwatering symptoms

The symptoms of these two very distinct ailments may appear like what one would expect from an untrained eye.

This is due to the fact that in both instances the issue begins at the root, which is not able to provide the plant with nutrients and fluids.

A plant that is dry will not have enough water to supply nutrients to the leaves and stems and leaves, whereas a plant that is overly moist will begin to drown as the root system gets overflowing.

Too much water and also too little water consequently, produce similar signs.

When you’re using the Petunia excessive watering can result in flowers dropping and leaves falling. The stems and leaves appear to be soggy.

When a plant is submerged, the stems and leaves become dry and crisp when the process of wilting takes place.

Signs of Overwatered Petunia

There are a variety of indicators which will indicate that water overflow is the problem you’re facing in your Petunia.

Petunias that are wilting can begin to lose its shape and appear to be in a state of disarray. If you examine it more closely, you’ll notice how the leaves appear wet instead of dry, which could suggest that there is not enough water.

Brown Leaves They will turn brown, but they will retain an acrid texture. If the condition continues to worsen the leaves may change to yellow and begin to fall.

Edema: This sign appears due to the fact that the plants’ cells are beginning to degrade and explode.

It may appear anywhere on the leaf, but is more noticeable on the underside of leaves. Check for bumps with watery appearance with a similar look like blisters.

Wet soil It is the indication that I find the most evident. If your plant shows any of the above signs, an examination of the soil in the pot will confirm the diagnosis.

If the water is abounding it is likely that the overwatering is responsible for the signs.

Root Rot: When the overwatering gets excessive, the roots begin to rot.

Roots that are damaged by rot cannot fulfill their primary task of carrying vital nutrients throughout the plant.

You’ll be able to recognize this problem because the roots turn brown and then become soft.

How to Fix Overwatered Petunias

It is imperative to act quickly now once you’ve discovered the issue. These are steps you need to take to keep your petunia from being overwatered.

Step 1: Tip Petunia from Pot

Remove the plant out of its container and allow the excess water to begin to drain away, so that air can be reintroduced back into the soil.

To speed up the process, place your rootball on a piece of paper and allow it to dry out.

The drying process should take between two and three days. Ensure that the plant isn’t exposed to direct sunlight at any time during the drying process.

The stems and roots are in a fragile state in this moment. If the plant is exposed to too many light sources it will be able to transpire more quickly.

In this stage of delicateness it is important for the plant to hold onto all the reserves that it has.

As the roots begin to dry, the root ball will begin to absorb some air and then turn back to slightly damp.

Many people advocate the idea of pressing the root ball to speed up drying. I do not ever do this because I believe the risk of damaging the roots far too high.

Step 2: Trim off Infected Roots

After the soil has dried, it’s the time to consider the possibility of repotting your Petunia. Before doing that you should take a look at the root ball to make sure that it isn’t rotting.

Root rot is often a result from excessive watering. Healthy roots are strong and white. Roots that are beginning to decay, die, and change color to an orange-brown.

In the meantime they lose their the texture and get wet. The brown pieces are not suitable for use.

It is best to cut them off using a pair of scissors until you have the healthy and clean root material.

Make sure you clean the cutting blades after this procedure because they can easily transmit the disease to other plants.

Step 2: Ensure Drainage Capacity of The Pot

The next thing you’ll have to check is that the container that your petunia will be placed in is able to drain properly.

Insufficient drainage capacity could have caused this issue in the first place.

If the water is not able to find a way to escape, it’s only an issue of time until the root ball gets wet and the plant starts to be affected.

There must be at least one hole at the inside of the pot and it should be big enough to allow you to insert your fingers into.

Step 3: Repotting Petunia

The next step is to get an excellent quality potting soil. Petunia’s aren’t too picky in regards to soil quality.

Do not reuse the soil that might have fallen off the root ball after you removed it out of its container.

First of all, it’s likely still damp. Secondly it could be carrying pathogens that can cause further harm to your already weak plant.

Here are some important things to be aware of when repotting:

  • It is recommended to repot your plant in the same size as the one it was taken from. It should also sit in the same level as the plant was originally established.
  • The soil’s top should be about 1 inch beneath the top of the container. The space between the soil’s top and the pot’s top allows you to water your plant without the soil slopping all over.
  • Put some soil at the bottom of the container , and then place the plant to ensure whether the depth is correct. If not, you can add or remove soil according to the needs.
  • When you have the Petunia in the exact depth you desire, fill the root ball with new soil, and gently press the soil in using your fingers.
  • You should remove air pockets, but you should not to make the soil too dense or cause damage to the roots when you backfill.
  • Then, put the pot inside an ornamental saucer, but keep your plant to rest in a low lighting position for a day, or until you notice the plant is beginning to grow.
  • Once you’ve repotted your Petunia Don’t be rushing to water it. There’s probably still some water lingering around the root ball due to the near-death experience. the soil that you have used to plant it will likely be a bit damp.
  • It is probable to take at most three days before your plant requires watering. When the plant begins to look healthier then you can shift it to a location which has more direct sunlight and apply the watering procedure below.

While a healthy petunia needs lots of sunlight, even if you grow it indoors It should be brought back to the sunlight gradually.

If you place it in the sun too fast, it could be affected and then wilt because the root system may not be in top condition.

Place your plant in sunlight for about an hour the first day after repotting. Then, increase the amount over the time of one week.

At that point, it will be back to its former self, and capable of enduring many hours of direct sunlight every day. If the plant isn’t getting enough light or light, it’ll either produce tiny flowers or not produce any even.

How to Water a Petunia

If they are planted in their common garden, the Petunia’s are extremely tolerant of dry weather they can be able to water only every week.

If you’re growing the plant inside a pot and you’ll have to pay closer focus on the way you water your plants.

Watering Rules

Always water your plants at the top of the soil , but don’t water the leaves or flowers.

If the water is stagnant in the upper areas of the plant, it lends to the development of fungal diseases , to which plants are susceptible.

By focusing on the base of the plant while watering it, you can reduce the risk significantly.

Watering Frequency

The most reliable way to determine the time to water is touching the soil’s surface using your fingertips. If the soil is dry, then it’s the right time to water.

A lot of times people drink water because they believe it’s the right the right time to do it and without any other reason other than that.

It is the level of moisture of your soil that will determine how often you water instead of a intuition.

Factors Influence Watering Frequency

The reason you should check your soil each day is because there are many variables that determine the amount of water your Petunia needs.

A bigger plant will release more water and thus need to be watered more frequently than a smaller one.

If the air is humid, the soil will hold more water than it would in the event that the air around it was dry.

As the soil ages it’s ability to hold on to moisture decreases, and the water is able to drain more quickly.

All of these elements work together to determine how often you should be able to drink water, and they are always changing.

Something as basic like the quantity of sunlight that hits the plant could alter the rate of how it uses the water that is available.

A simple check of your finger on the soil’s surface will help provide you with more accuracy that any other technique. It is also evident you that your back fingers have more sensitivity than your front.

How Much and When to Water

If you notice you can see that the top of your dirt is dry it’s time to water it again. Apply the watering container to your soil’s surface until you can see the water beginning to appear through the drainage holes at the base of the container.

This will be an indication that the plant has had an extensive soak.

When that happens when it does, let the water disappear completely. The excess water could overflow your plant’s saucer.

If this occurs, you must remove the water until you can be sure that it doesn’t hinder the draining of water that is accumulating within the soil.

It is possible to repeat this a couple of times in the course of one watering.

Think about the pot you plant your petunia in. Terracotta pots, like are porous, and tend to shed moisture faster than clay that is glazed or plastic.

This isn’t a reason to not choose an extra porous pot, but you must consider the speedier rate of evaporation.

What you are trying to achieve is a steady amount of moisture, without the soil getting soaked and this method is the most efficient method to achieve that.

Do not get caught up in the details of the frequency of watering or how much drink. Just rely on the touch test to determine what your Petunia requires.

Most gardeners who are new aren’t confident and tend to look at an agenda as a method of watering instead of relying on their intuition.

Even experienced gardeners often water on specific days of the week , rather than testing to determine whether the water is required or not. The consequences could be fatal to your plants in the house.

Water Quality

If you can access rainwater, water that has been filtered or distillate water it is the water you choose to drink.

The water from your tap has been through a chemical process to eliminate the contaminants. It doesn’t matter if require occasionally.

If you are using it for an extended period of time but, the chemicals end up accumulating in the soil as salts, and can be harmful to the health of plants.

Common Mistakes and Solutions

The area of watering is where it’s easy to make things wrong until you know the goal you’re trying to accomplish.

When that happens when that happens, you will realize how simple it is to make things work and be wondering why you went off course in the beginning. Here is a table listing the most frequent watering mistakes.

Final Words

If you keep it inside Your Petunia can provide you with an attractive and unique house plant. They are simple to maintain, however the overwatering could quickly turn into an problem.

Do not let it put your off, as it is a skill you can master in a the shortest amount of time.

After you’ve learned to water your plants correctly following the techniques I’ve previously discussed, you will be a very content and healthy plant.
