Why do I keep overwatering my houseplants? The secrets of watering revealed

This article will certainly be useful for all growers who give their plants all their love but still keep overwatering them. Do not worry: you are not alone. Overwatering is one of the most common mistakes our customers confide in us about. Many beginners have it ingrained in them that a plant should not get too much water because that leads to waterlogging. This belief often means that plants do not get as much water as they actually need, which is especially true for tropical plants that prefer a moister environment. But what if we told you that the problem with overwatering is not the amount of water you give your plants, but how often you water? And what if moist soil is not as harmful as many of us think?

Understanding how to water plants properly is key to their overall health and survival. It is not as simple as watering them when you think they are thirsty or when the soil looks dry. The art of watering takes into account a number of factors, such as the type of plant, its native environment, its current environment, the season and even the type of planter it is in.

In this article, we will help you understand how to recognize overwatering, how to avoid it and, above all, how to find the right watering balance for your tropical plants to make sure that they not only survive but thrive.

When we talk about overwatering, many people picture a plant drowning in water. However, it is not that simple. Overwatering is not so much about the volume of water you give your plants, but rather about how often you water. Plants do not like their roots sitting in water for long periods, because this can lead to root rot and other diseases. Overwatering happens when plants are watered too often, not when they get a large amount of water at once. It may seem counterintuitive, but at every watering, plants need the potting mix to be soaked thoroughly all around the planter and then left to dry out to a certain depth (which varies from plant to plant).

Understanding tropical plants

To understand the concept of overwatering and why watering frequency matters more than quantity, take a moment to consider where tropical plants actually come from and what they are adapted to. In their natural environment, tropical plants are used to a cycle of heavy rains followed by a period of drying out. The soil they grow in usually dries quickly, which means that even though they get a lot of water, the excess does not stay in the soil and does not cause problems.

 

 

These plants are adapted to store water in their leaves, stems or roots, which allows them to survive until the next downpour. That is why tropical plants can handle (and even prefer) a thorough watering, as long as we give them time to use up the stored water before the next watering.

At home, we imitate this natural cycle by watering our plants thoroughly, waiting until the top layer of soil dries out, and only then watering them again. (The easiest way to check is to stick a finger into the potting mix and, if it is dry, give the plant a good soak.) This method ensures that we do not just pour water onto the soil, but let the plant absorb the water it needs, store it and then use it up before it gets more.
 

So what are the signs of an overwatered plant?

Yellowing leaves:

Although yellow leaves can be a sign of several problems, one of the most common causes is overwatering. If you notice that your plant’s leaves are turning yellow, especially if they come with brown spots, it may be a sign that you are watering too often. When the roots are constantly wet, they lack oxygen, which stresses the plant, and this often shows up as yellow leaves.

 

Wilting:

You might think that wilting plants need more water, but that is not always the case. Too much watering can also cause plants to wilt. When a plant gets too much water, its roots can become waterlogged and short of oxygen, which leads to limp, wilting leaves. It is a bit ironic that both overwatering and a lack of water can cause wilting, which is why it is very important to check the soil moisture before you reach for the watering can.

 

Root rot:

This is one of the most serious signs of overwatering. Root rot occurs when a plant’s roots stay in water for too long, which leads to the growth of fungi and bacteria that can cause the roots to decompose. This rot can be fatal to the plant because it limits its ability to take up water and nutrients. You may only spot root rot at an advanced stage, but if you notice an unpleasant smell or a mushy feel when you touch the soil, it is time to check the plant’s roots.

 

These symptoms are essentially the plant’s call for help. By recognizing them early, you can adjust your watering habits to better suit your plants’ needs. It is important to realize that it is easier to revive an underwatered, dry plant than to save an overwatered one. When in doubt, it is better to hold off on watering for a few days until you are sure the plant needs it.

Overwatering can significantly affect a plant’s overall health and growth. A plant with waterlogged roots is essentially a plant that is trying to breathe but cannot. It is a stressful situation that can lead to weak and slow growth.

Plants need a balance of air and water around their roots to grow efficiently. Overwatering disrupts this balance and limits the plant’s ability to take in oxygen, which leads to poor growth and poor overall plant health. In severe cases, overwatering even leads to the death of the plant.

As you can see, overwatering is a serious problem with potentially disastrous consequences. But you do not need to worry: overwatering is, above all, a problem that can be prevented. In the next section, we will share tips on how to avoid overwatering and keep your plants healthier and happier.

Proper watering techniques for tropical plants

Knowing how and when to water tropical plants is the key to preventing overwatering and encouraging a thriving jungle. Let’s take a look at the techniques that will help you strike this delicate balance.

When does a plant actually need water?

Contrary to popular belief, watering should not follow a strict schedule alone. Instead, a more effective approach is to respond to the plant’s needs. You can do this by checking the soil moisture.

One reliable way to find out whether a plant needs water:

Simply stick your finger about 2 cm deep into the soil. If the soil is dry at this depth, it is time to water the plant. If the soil is still moist, however, wait a few more days and check it again.

 

Effective tips for watering tropical plants

One of the decisive factors in proper watering is using well-draining soil. Tropical plants evolved in the well-draining soil of rainforests and prefer a similar environment in your home too. Use a well-draining soil mix, such as our all-purpose houseplant mix or our aroid mix, which contains coconut chips and pine bark that help the potting mix drain well instead of holding water. When watering, make sure to soak the plant thoroughly. This means watering until a little water drains out of the bottom of the planter. This ensures that the water has reached all parts of the root system, which supports healthier growth.

Light and humidity play a key role in determining how often to water your plants. Plants in brighter light tend to dry out faster than plants in low light. Likewise, soil dries out faster in a dry environment than in a humid one. It is important to keep an eye on these factors in your home too and adjust your watering routine accordingly.

 

Do not forget that every plant is unique and may have slightly different water requirements. Observation and adjustment are the key to understanding what your particular plant needs.

Frequently asked questions about overwatering

To wrap up our article, let’s look at the frequently asked questions we get from you.

Can a plant recover from overwatering?
Yes, most plants can recover from overwatering, especially if it is caught in time. The first step is to stop watering immediately and let the soil dry out completely. If your child, friend or neighbor overwaters your plant while you are on vacation, you can, for example, use paper tissues to soak up the excess water. In more serious cases, such as root rot, further steps may be needed, such as removing the damaged roots and repotting the plant into fresh, dry potting mix.
In extreme cases, we recommend taking cuttings from the overwatered plant, removing the rotten roots, letting the cutting root again and starting over. 

How often should I water my plant?
There is no one-size-fits-all answer to this question. Watering frequency depends on many factors, including the type of plant, its size, its environment and the season. A good rule of thumb for most houseplants is to water them when the top two centimeters of soil have dried out. Some plants, such as succulents and cacti, prefer their soil to dry out completely before watering.

Why are my plant’s leaves turning yellow?
Yellow leaves can be a sign of several problems, including overwatering. When a plant is overwatered, it is not only waterlogged but also short of oxygen. This lack of oxygen can cause the leaves to turn yellow. If you notice yellow leaves, check the soil moisture. If it is wet, the cause may be overwatering. However, yellow leaves can also be a sign of a pest infestation (e.g., spider mites), so it is always best to check the texture of the yellow leaf. Is something moving on the leaf? Then it may not be overwatering but a pest infestation. 
If the plant is not infested and you are watering correctly, the last possibility is a lack of nutrients. Treat your plants to a high-quality fertilizer.

Is it better to let plants dry out for a long time or to overwater them?
As a general rule, it is better to let plants go without water for longer than to overwater them. Underwatering can lead to slower growth and wilting, but these effects are often temporary and can be fixed with proper watering. Overwatering, on the other hand, can lead to more serious problems such as root rot, which can be fatal to the plant.
Remember that mindful watering is a constant learning process, and occasional mistakes are part of it.
