Watering your plants is an essential part of keeping them healthy and vibrant. But have you ever wondered if there is a better way to water your plants? One method that has gained popularity in recent years is watering from the bottom. In this article, we will explore whether watering your plants from the bottom is indeed better and examine its benefits and drawbacks.

What is Bottom Watering?

Bottom watering, also known as sub-irrigation, is a watering technique where water is applied directly to the roots of plants rather than from the top. This is done by placing the plants in a tray or saucer filled with water, allowing the roots to absorb moisture through the drainage holes in the bottom of the pot.

The Benefits of Bottom Watering

There are several advantages to watering your plants from the bottom:

1. Prevents overwatering: When you water your plants from the top, it is easy to accidentally overwater them. Bottom watering helps prevent this by allowing the roots to take up only the amount of water they need.

2. Reduces the risk of fungal diseases: By avoiding water contact with the leaves, bottom watering can help reduce the risk of fungal diseases, such as powdery mildew or leaf spot.

3. Promotes stronger root growth: Bottom watering encourages roots to grow deeper in search of water, resulting in stronger and more resilient plants.

The Drawbacks of Bottom Watering

While bottom watering has its benefits, it is not without its drawbacks:

1. Limited effectiveness for certain plants: Some plants, particularly those with shallow root systems, may not benefit as much from bottom watering. They may still require occasional top watering to ensure proper hydration.

2. Potential salt buildup: If not properly managed, bottom watering can lead to salt buildup in the soil over time, which can be harmful to plants. Regular flushing of the soil and using distilled water can help mitigate this issue.

3. Requires careful monitoring: Bottom watering requires regular monitoring to ensure that the plants are getting enough water and that the tray or saucer is not left with stagnant water, which can lead to root rot.

How to Bottom Water Your Plants

If you decide to give bottom watering a try, here are some steps to follow:

1. Select a tray or saucer that is slightly larger than the pot of your plant.

2. Fill the tray or saucer with water until it reaches about a quarter inch high.

3. Place the plant pot in the tray, ensuring that the drainage holes are in contact with the water.

4. Allow the plant to absorb water for about 30 minutes to an hour, or until the top layer of soil feels moist.

5. Remove the plant from the tray and allow any excess water to drain away.


While bottom watering can be beneficial for certain plants, it may not be suitable for all. Consider the specific needs of your plants and the potential drawbacks before deciding to switch to this watering method. Regular monitoring and proper care are essential to ensure the health and well-being of your plants, regardless of the watering technique you choose.
