The most important part of macrobonsai care is watering. The frequency of watering the tree depends on different factors (tree species, tree size, size and shape of the tray, season of the year, soil mix and climate) which means that it is impossible to say how often you should water your Bonsai However, if you understand a few basic rules, these will help you know when your Bonsai needs to be watered.

How often should I water my macrobonsai?


As stated above, the frequency of watering depends on many factors to provide an exact rule. Instead of routinely watering, you need to learn to observe your trees and learn when to water. Of course a very hot climate or the existence of wind will make you have to water more frequently. The following recommendations will help you properly water your macrobonsais:

Water your Bonsai when the soil is slightly dry
This means that you should not water your macrobonsai when the soil is still wet, only when it is slightly dry. You can use your fingers to control the humidity on the surface (and inside) of the soil. When you gain experience you will be able to see (and notice) when a tree needs to be watered.

Never water your trees routinely
Observe your trees individually rather than watering them with a daily routine until you know exactly what you are doing.

Use the right soil mix
The soil mix has a great influence on how often you should water it. For most Bonsai, a mixture of akadama, pomice and volcanic rock mixed in a ratio of ½ – ¼ – ¼ may be fine. However, you should use a mixture that retains more water (for this use a higher proportion of akadama) when you cannot water your trees often enough. Read the article on Soil Mixes for Bonsai for more detailed information on this topic.


When should I water?


It doesn’t really matter what time of day you water although it is recommended not to water regularly at noon. At that time the pot and the soil are very hot due to sunlight, irrigation would lower its temperature very quickly when watering with fresh water. Anyway, it will always be better to water than to let our trees dry under a scorching sun!
