How to Tell if Coleus Plant Needs Watering?

Updated: April 25, 2022

Coleus plants are some of the most colorful and easy-to-grow houseplants, making them very popular among gardeners. However, even though they are relatively low-maintenance, they still require proper care and attention to thrive. One of the most important aspects of care is watering. In this article, we will discuss how to tell if a coleus plant needs watering.

Signs that a Coleus Plant Needs Watering

  1. Soil Dryness

The most obvious sign that your coleus plant needs watering is when the soil is dry to the touch. Stick your finger into the soil about an inch deep. If it feels dry, then it’s time to water your plant.

  1. Drooping Leaves

Another indication that your plant needs water is when its leaves start drooping or wilting. This happens because the plant is losing water faster than it can absorb it from the soil. If you notice this happening, water your plant immediately.

  1. Yellowing Leaves

Yellowing leaves are another sign that your coleus plant may need watering. When the plant is not getting enough water, it will start to shed its older leaves to conserve energy.

  1. Stunted Growth

If your coleus plant is not growing as fast as it should be, it could be due to lack of water. Plants need water to transport nutrients from the soil to their leaves and stems. Without enough water, growth will slow down.

  1. Dry Potting Mix

If the potting mix is dry and pulling away from the sides of the container, this indicates that the coleus plant is in dire need of water.

How to Water Your Coleus Plant

Now that you know how to tell if your coleus plant needs watering, it’s important to know how to properly water it.

  1. Water Only When Needed

Never over-water your coleus plant. Only water it when the soil is dry to the touch, as over-watering can lead to root rot and other problems.

  1. Water at the Base

When watering your coleus plant, make sure to water at the base of the plant, not on top of the leaves. This helps prevent fungal diseases and keeps the foliage dry.

  1. Use Room Temperature Water

Use room temperature water because cold water can shock the plant’s roots and hot water can scald them.

  1. Use a Moisture Meter

If you are unsure whether your coleus plant needs watering, use a moisture meter to measure the moisture level in the soil.


How often should I water my coleus plant?

You should only water your coleus plant when the soil is dry to the touch, which typically means watering every 7-10 days.

Can I water my coleus plant with tap water?

Yes, you can use tap water to water your coleus plant, but be sure to let it sit for 24 hours before using it to allow any chlorine or fluoride to evaporate.

Can I mist my coleus plant?

While misting can be beneficial for some plants, it is not necessary for coleus plants. In fact, it can promote fungal diseases if done excessively.

Is it better to underwater or over-water a coleus plant?

It is better to slightly underwater than over-water a coleus plant. Over-watering can lead to root rot and other problems that can kill the plant.
