What Is Bottom Watering and How Does It Benefit Plants?
What Is Bottom Watering?
Bottom watering, also known as reverse watering, is a method of watering potted plants where water is added to a saucer or tray placed beneath the pot instead of pouring it directly onto the plant.
This technique relies on the use of drainage holes in the pot to allow the water to be absorbed by the potting medium from the bottom up.
By saturating the potting medium from the bottom, bottom watering provides controlled hydration to plants and helps prevent issues such as fungus gnats.
It is particularly beneficial for plants with hairy or fuzzy leaves, plants that don’t like getting their leaves wet, and plants grown in soilless mixes.
Bottom watering is also useful for large containers as it aids in flushing out soluble salts and fertilizer build-up.
To bottom water, the pot is placed in a sink or tub with room-temperature water or distilled water, allowing the potting medium to absorb moisture.
Once the potting medium is saturated, the pot is removed from the water and allowed to drain.
Key Points:
- Bottom watering is a method of watering potted plants by adding water to a saucer or tray beneath the pot.

Did You Know?
1. Bottom watering is a method of hydrating plants where water is applied directly to the roots from the bottom rather than from the top.
2. This technique is commonly used for plants that are sensitive to moisture on their leaves, such as African violets.
3. Bottom watering helps prevent the spread of diseases and pests, as it reduces the likelihood of water splashing onto the foliage.
4. This method also encourages deep root growth, as plants are motivated to extend their roots downward in search of water.
5. One interesting fact is that bottom watering can be done by placing the plant’s pot in a tray of water, allowing the roots to soak up the water through the drainage holes.
What Is Bottom Watering?
Bottom watering is a technique used for watering potted plants by adding water to a saucer or tray beneath the pot instead of directly pouring water onto the soil surface. This method is also known as reverse watering because it involves reversing the traditional top-down watering approach. By placing water in the saucer, the plant absorbs moisture from the bottom up, allowing the roots to take in water as needed.
Traditionally, plants are watered from the top, which can sometimes lead to problems such as over-watering or uneven moisture distribution. By using the bottom watering method, water is provided directly to the roots, ensuring more efficient absorption and preventing water from resting on the leaves or stem, which can increase the risk of diseases and pests.
Benefits of bottom watering include:
- Efficient absorption by the roots
- Prevents over-watering and uneven moisture distribution
- Reduces the risk of diseases and pests by keeping water off the leaves and stem
“By using the bottom watering method, plants can receive water efficiently and minimize the risk of water-related issues.”
Benefits Of Bottom Watering For Potted Plants
Bottom watering has several benefits for potted plants. One of the main advantages is the prevention of water-related issues, such as fungus gnats. Fungus gnats, attracted to moist environments, can cause damage to plant roots. Bottom watering helps keep the soil surface dry, reducing the likelihood of fungus gnat infestations.
Plants with hairy or fuzzy leaves, as well as those that don’t tolerate wet leaves, can also benefit from bottom watering. With water being absorbed directly through the roots, the leaves remain dry, preventing potential damage or disease caused by prolonged moisture on the foliage.
Additionally, plants grown in soilless mixes, dense leaf cover, or those that can be damaged when wet, such as succulents or delicate flowers, can thrive with bottom watering. This method allows for controlled watering, ensuring that the potting medium is neither too dry nor oversaturated.
Choosing The Right Potting Medium For Bottom Watering
To successfully implement bottom watering, it is essential to select the right potting medium. A well-draining mixture is crucial, as it allows water to flow freely through the soil and encourages healthy root growth. The potting medium should include a combination of materials such as peat moss, perlite, and vermiculite to ensure adequate drainage and water absorption.
The saturation of the potting medium should be carefully monitored to avoid waterlogging the plants’ roots. It is important to find the right balance, as both excessive dryness and oversaturation can harm the plant. By observing the moisture level of the potting medium, you can ensure that the plants receive the ideal amount of water for their growth and development.
Preventing Fungus Gnats With Bottom Watering
One of the significant benefits of bottom watering is preventing fungus gnats from wreaking havoc on potted plants. Fungus gnats are attracted to moist environments, especially those with damp topsoil. By watering from the bottom, the soil surface stays dry, which makes it less hospitable to these pests.
To further deter fungus gnats, it is important to use a well-draining potting medium and avoid over-watering. Additionally, minimize evaporation by placing decorative elements, such as pebbles or moss, on the soil surface. These barriers create a dry layer, making it less appealing for fungus gnats to lay their eggs and propagate.
- Bottom watering prevents fungus gnats
- Well-draining potting medium deters pests
- Avoid over-watering to discourage gnats
- Use decorative elements to minimize evaporation
- Dry soil surface makes it less appealing for gnats to lay eggs and propagate
Remember to regularly inspect your plants and take prompt action if you notice any signs of fungus gnat infestation.
Proper Techniques For Bottom Watering
To effectively bottom water your potted plants, follow these proper techniques:
- Start by placing your plant in a pot with drainage holes to ensure excess water can escape.
- Fill a saucer or tray with room-temperature water and place the pot on top, allowing the water to be absorbed through the holes.
- Allow the pot to sit in the water for about 10-20 minutes or until the top layer of soil feels moist. This will allow the roots to absorb the necessary amount of water.
- Once the desired moisture level is reached, remove the pot from the water and let it drain properly.
It is important to note that bottom watering does not replace the occasional need for proper flushing. Over time, soluble salts can accumulate in the potting medium, leading to fertilizer buildup and potential damage to the plants. To avoid this, occasionally flush out the excess salts by thoroughly watering the plant from the top until water runs freely out of the bottom drainage holes.
bottom watering is a beneficial technique for potted plants that provides efficient water absorption, reduces the risk of water-related issues, and promotes overall plant health. By choosing the right potting medium, preventing fungus gnats, and following proper techniques, you can ensure your plants thrive in a well-watered and healthy environment.

Frequently Asked Questions
What is the purpose of bottom watering?
Bottom watering is a technique that involves pouring water directly into the saucer or tray underneath a potted plant, allowing the water to be absorbed through the drainage holes. This method serves to provide plants with the ideal amount of water while ensuring it is evenly distributed throughout the soil. By allowing plants to take up water from the bottom, bottom watering helps prevent overwatering and promotes healthier root growth. This technique is particularly useful for potted plants with drainage holes, providing them with a reliable and efficient method of water uptake.
Can you overwater by bottom watering?
Bottom watering is a method that allows the plant to absorb the water it needs at its own pace, making it a plant-led approach to watering. While it is not impossible to overwater using this method, it is considerably less likely compared to other watering techniques. Additionally, sensitive leaves are not subjected to the direct impact of water pouring over them, which can contribute to the plant’s overall happiness and well-being.
What is the difference between top and bottom watering?
While top watering plants is quicker and easier, bottom watering offers some advantages. With bottom watering, you need to monitor the watering time and avoid over-soaking the plant, making it a more time-consuming process. Additionally, the uptake of water is slower for plants in bottom watering, allowing for a gradual and efficient absorption.
How long should I bottom water?
For ideal bottom watering, it is recommended to let your potted plant soak in the bathtub, sink, or a container filled with a few inches of water for approximately 15 to 20 minutes. During this time, the plant will absorb just the right amount of water, ensuring it receives the perfect balance without being deprived or oversaturated. This method allows for efficient watering and prevents the risk of overwatering or underwatering your plant, promoting its healthy growth and development.
