Watering Plants From The Bottom- 10 Basic and Simple Tips and Tricks

There are several methods of watering houseplants: top watering from above with a watering can, dipping plants in a bowl of water and draining them, or even letting them drink from below. Plants usually have a preference as to which method they should use.

Whatever method you choose, room temperature is the best, soft, distilled water or rainwater. When it is time to water, let the water fully saturate the soil. After watering, let the water run out of the bottom of the pot and discard the excess water from the drainage plate. Don’t expose to extremely bright light immediately.

Now that your plants grow in the right light and the right temperature; the next urgent need may well be a drink. The reason plants need water is that minerals such as phosphorous, potassium, and magnesium are dissolved in the soil water and absorbed by the roots, along with the water.

Watering your plants from the bottom is also called reverse watering because instead of pouring the water on top of the surface from the top, you let your plants drink from below.

Why Water From Below

If your plant has hairy leaves or the foliage covers the compost, you want to water from the bottom in order to avoid splashing the leaves.

The reason why you want to avoid splashing the leaves is that some plants like African violets, Snake plants, and Cyclamen are prone to fungus and bacteria if their splashed leaves don’t dry out properly before being exposed to bright light. Splashing the leaves will also create ugly marks and lead to the leaves rotting.

Next, bottom watering helps to develop stronger root systems as sometimes plants don’t get all the benefits of watering if you don’t water thoroughly. Moreover, bottom watering plants minimize the risk of pest infestation, fungus, and diseases.

Another reason you want to water from below is if your plant is wilting due to underwatering. So, if you have forgotten to water your Peace Lily, watering from below will revive it within an hour. Here follows how to bottom water.

How to Water Plants From the Bottom

The main thing here is to select pots with enough drainage holes. If not, the plant won’t be able to absorb water.

Secondly, it is best to use room-temperature water, ideally soft and distilled water. You can enrich it by using a water-soluble fertilizer or banana peel fertilizer to improve soil structure a bit.

Thirdly, bottom watering takes more time than top watering. You need to allow time for plants to absorb water properly. Allow at least 15 minutes for smaller and medium-sized plants, while larger plants will need more time. Use the finger test after 15 minutes to check the soil moisture.

You want to fill in your bowl, tray, or bucket with enough water, between a few inches to half depending on the size of the pot and plant. Smaller plants need less water.

Method 1: Stand the smaller potted plants in a saucer or tray of water for between 15 and 30 minutes depending on the type of the plants. Drain afterward.

Method 2: You can also move plants somewhere shady and fill a bowl or container large enough with tepid water. In just their plastic pots with drainage holes, dunk your plants into the water, weighing them down if they start floating. Soak for around 30 minutes and drain. This is an especially good method if your plant is wilting due to underwatering.

Method 3: Watering from the bottom is also possible if you put your plants in a tub or sink that is filled with a few centimeters of water. The water will get absorbed through the roots without waterlogging the soil. Most plants in larger containers will love this with their dry soil. Don’t shower plants with sensitive leaves like ferns.

You always want to drain any excess water from the saucer. Weigh the pot in your hands to check the water level and see if it has been saturated enough. This will also help you determine when you should water next time.

You don’t want to repeat this procedure too often because it will lead to overwatering and rotting.

Aim to make the compost moist, but not wet, as sitting in soggy compost will lead to root rot, so make sure to let the excess water drain away.

Compost in terracotta pots dries out more quickly than in plastic pots, but don’t water to a timetable. Get to know your plant’s needs instead. Poke a finger into the soil to test it. Also, a very light pot will have dry compost. That will be your guide.
