Watering plants from the bottom is a gardening technique gaining traction for its numerous benefits. As an avid gardener, I’ve seen how this method can revolutionize plant care. It’s an approach that goes against the traditional ‘top-down’ watering that most of us are familiar with. But what exactly does watering plants from the bottom entail, and why is it so beneficial?

The concept might seem counterintuitive at first. After all, we’re used to rain from above, watering our plants from the top down. But in reality, the roots, the plants’ primary means of absorbing water, are at the bottom. Watering plants from the bottom ensures the roots get the moisture they need without overwatering them or causing other issues, such as root rot.

Over the years, I’ve noticed an improvement in my plants’ overall health and growth since I started watering plants from the bottom. It’s a method that promotes healthier roots and, by extension, healthier plants. But before discussing the benefits, let’s first understand what bottom watering is and how it works.

What is Bottom Watering, And How Does it Work?


Bottom watering plants is just as it sounds. It’s watering plants from the bottom up. Instead of pouring water onto the soil from above, you place your plant pot in a tray or container filled with water. The pot’s drainage holes at the bottom allow the water to seep into the pot, and the plant’s roots absorb the needed moisture.


Water Plants From The Bottom Up (Reverse Watering)


This method allows the water to be soaked up into the soil. This ensures that the roots, the plant’s primary source of hydration, get the water first. This process might seem slow initiallybriefly, but it’s an effective way to ensure your plants get just the right amount of water they need without risking overwatering.


It’s Also Quite Passive and Allows You Less Active Watering


We just let each plant sit in a tray of water for a short time. Some potted plants live in a bottom watering pot. But most of ours lo sit, partially submerged in room-temperature water.

The science behind how to bottom water is quite fascinating. It’s based on a principle called capillary action. But what does this mean, and how does it affect our plants? Let’s dive into the science behind bottom-watering plants.


Using a Wick


Some choose to use a wick to keep certain plants watered.


Wick watering is a method of watering plants using a wick material to draw water from a reservoir into the plant’s soil via capillary action. To wick water your plants, you can follow these steps:


  • Make a knot on one end of a ⅛ to ¼ inch (3-6 mm) thick nylon rope.
  • Take your plant out of its pot and stick the other end of the wick into the center of its roots.
  • Thread the wick through the pot’s drainage hole.
  • Repot your plant and set it over a 16-32 oz. (0.5-0.9 L) vessel of water, and submerge the wick.
  • Alternatively, fill a bucket or other container with water. Place it near the plants. Cut a piece of lantern wick long enough to reach from the bottom of the water reservoir to several inches below the soil’s surface. Place one end of a wick several inches into the soil’s surface and the other into the reservoir.

The Science Behind Bottom Watering Plants


Capillary action, also known as capillarity, is a process where liquid moves within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension. This process is what makes bottom-watering plants possible. When you place your plant pot in a water tray, the soil acts as a porous material. The water is then drawn into the soil, hydrating your plant from the bottom up.


The beauty of capillary action is that it allows the plants to take up just the amount of water they need, preventing overwatering. It’s a natural process that ensures the plant’s roots are adequately hydrated, promoting healthier growth.


This science-backed method of watering plants from the bottom has numerous benefits, which we will now explore.

Benefits of Watering Plants from the Bottom


One of the main benefits of watering plants from the bottom is that it promotes more robustrobust root growth. By ensuring that the water reaches the roots first, we’re encouraging the roots to grow deeper into the soil, seeking out the moisture. This results in a plant with a strong, healthy root system, which is crucial for overall plant health.


Secondly, bottom watering minimizes the risk of disease and pest infestations. Overhead watering can leave foliage wet. This creates a perfect environment for fungal diseases and pests. Watering from the bottom keeps the plant’s foliage dry, reducing the chances of disease and pest problems.


Thirdly, bottom watering is efficient. It reduces water waste as the water goes directly to where it’s needed most – the roots. This method also ensures that all the water is absorbed and none is lost to evaporation.

Does Bottom Watering Work for All Plants?


While bottom watering benefits most plants, certain types may respond poorly to this method. Succulents and cacti, for example, prefer dry conditions and might suffer from root rot if left in water for too long.


On the other hand, plants that love water, like ferns and peace lilies, thrive with bottom watering. It’s essential to understand the specific water needs of your plants before deciding on the best watering method.

Choosing the Right Bottom Watering Pot for Potted Plants


Choosing the right pot is vital for successful bottom watering. The key is to select a pot with drainage holes at the bottom. These holes allow the water to seep into the pot, facilitating the capillary action needed for bottom watering.


Ceramic or terracotta pots are ideal as they are porous and allow water to be absorbed into the pot. This promotes even better hydration for your plants. However, plastic pots can also work well if they have proper drainage holes.

Tips for Successful Bottom Watering


Please remember the following tips to ensure bottling is slow and you have successful bottom watering.


First, please remove your plant from the water tray once it has absorbed enough water. Leaving the plant in standing water can lead to waterlogged soil and root rot.


Second, please check the moisture level of your plant’s soil. Overwatering can be just as harmful as underwatering. So make sure your plant’s soil is dry.


Lastly, bottom watering is a slow process. The water might take some time to absorb, so be patient and allow your plant to take up the water it needs.

Common Mistakes in Bottom Watering and How to Avoid Them


While bottom watering has many benefits, there are some common mistakes to avoid.


One mistake is not allowing the plant to drain after watering. After your plant has absorbed the water, please remove it from the water tray and allow any excess water to drain out.


Another common mistake is watering too frequently. Even though the water is absorbed from the bottom, you can still water your plants more often. Overwatering often leads to root rot and other issues.
