How Much Watering Does Your Bonsai Plant Need:
A Comprehensive Guide

Updated: June 11, 2023

Bonsai plants are a beautiful addition to any indoor or outdoor space. But with that beauty comes the responsibility of proper care, including watering. Watering is one of the most important aspects of bonsai care, and it can be easy to over or under water your plant. In this comprehensive guide, we will discuss everything you need to know about watering your bonsai plant.

Understanding Your Bonsai Plant’s Water Needs

Bonsai plants have unique water needs compared to other plants. They have a small root system and are usually planted in shallow containers, which means they dry out quickly. However, they also don’t like to sit in water for too long, as this can lead to root rot.

The amount of watering your bonsai needs depends on several factors, such as the type of tree, the size of the pot, the soil type, humidity levels, and the environment it’s in.

Signs Your Bonsai Plant Needs Water

One of the easiest ways to tell if your bonsai plant needs water is by checking the soil’s moisture level. Stick your finger about an inch into the soil, and if it feels dry, it’s time to water your plant.

Another way to tell if your plant needs water is by observing its leaves. If they look droopy or wilted, it’s a sign that your plant is thirsty. However, if the leaves are yellow or brown and crispy, it could be a sign of overwatering.

How Often Should You Water Your Bonsai Plant?

As mentioned earlier, there isn’t a one-size-fits-all answer to how often you should water your bonsai plant. However, there are some general guidelines you can follow.

During the growing season (spring through fall), most bonsai trees require watering every day or every other day. However, some trees may need more frequent watering than others. For example, a juniper tree naturally grows in arid regions and requires less water than a ficus tree.

During the dormant season (winter), most bonsai trees require less frequent watering, usually every three to four days.

Tips for Watering Your Bonsai Plant

  • Use room temperature water: Cold water can shock your plant’s roots, while hot water can damage them.

  • Water from above: Pour water over the soil until it starts to drain out of the bottom of the pot. This ensures that all parts of the soil get wet.

  • Don’t let your plant sit in water: Make sure to empty any excess water from the saucer below the pot after watering.

  • Use a moisture meter: If you’re unsure whether your plant needs water or not, consider using a moisture meter. This tool measures the soil’s moisture level and can help prevent over or under watering.

Q: Can I use fertilizer when watering my bonsai tree?

In conclusion, proper watering is crucial for keeping your bonsai plant healthy and thriving. By understanding your plant’s unique needs and following these tips and guidelines, you can ensure that your bonsai tree stays beautiful for years to come.
