Should You Water Plants from the Top or Bottom?

Proper watering is one of the most important factors in keeping your plants healthy and thriving. However, there is often confusion about whether you should water plants from the top or bottom. The answer to this question depends on several factors, including the type of plant, the type of soil, and the method of watering. In this article, we'll take a closer look at the pros and cons of watering your plants from the top or bottom, so you can determine which method works best for your garden.

Watering from the Top

One of the most common methods of watering plants is from the top, using a watering can, hose or sprinkler. This method involves pouring water directly onto the soil around the plant, allowing the water to soak down to the roots. Watering from the top can be especially beneficial for plants that have foliage that needs to be washed, such as ferns or houseplants. It also provides a chance to inspect the plant for any pests or diseases.

However, watering from the top can also have some drawbacks. For one, it can cause water to evaporate quickly, especially on hot, sunny days. The water may also wash away some of the soil, expose the roots to the air, and contribute to the development of fungal diseases. Additionally, some plants may not be able to tolerate water on their leaves, which can lead to sunscald or other problems.

Watering from the Bottom

Watering from the bottom, also known as sub-irrigation or bottom watering, involves filling a tray with water and allowing the plant to absorb the water through the soil. This method allows the plant to take up water as it needs it, preventing overwatering or underwatering. It can also help prevent fungal diseases by keeping the foliage dry.

Watering from the bottom is especially beneficial for plants that have sensitive foliage or roots, such as African violets or succulents. It can also be a good choice for larger plants that may be difficult to move or water from the top. However, it can be more time-consuming than watering from the top, as you will need to refill the tray regularly and monitor the plant's water needs.

Choosing the Right Method

So, which method of watering is best for your plants? In general, the choice will depend on the specific needs of your plants, as well as your own preferences and gardening style.

If you’re growing plants with delicate foliage that shouldn’t get wet or ones that are susceptible to fungal diseases, such as African violets or succulents, then watering from the bottom may be the way to go. On the other hand, if you’re dealing with plants that have foliage that benefits from a light misting or if the soil dries out quickly, then watering from the top could work better. If you're unsure, you can always experiment with both methods to see which one produces better results for your garden.

Conclusion

Whether you should water your plants from the top or bottom depends on a variety of factors, including the type of plant, the type of soil, and the method of watering. Both methods have their advantages and disadvantages, so it's up to you to determine which one works best for your garden. In the end, the important thing is to provide your plants with the proper amount of water, at the right time, to keep them healthy and thriving.
