How to water your bonsai



Watering is a daily activity about growing bonsai's. Because of this reason, it is also the most repeatedly action. The result is, logically, that watering is one of the most important action. The difference between watering ordinary flowers and bonsai trees exist.

Bonsais are great complements to your garden furniture. It gives your garden an attractive appeal and a feel of elegance. That is why it's important to know how to properly water your bonsai. Bonsais are not your regular flower and plant. There is a proper method of watering these beautiful Bonsai trees. You have to know the reasons behind the logic of watering the bonsai trees. Follow the steps carefully on the following paragraph to ensure that you won't overdo it.

Before you can start watering you should understand the reasons why a plant requires water. Acceptance and transport of nutriments, carrying minerals into the place of their usage, maintenance of pressure inside cells, biochemical reactions; Every of these operations need water. Also, there must be a stability between incoming and outgoing water in plant elements. If anything causes violation of this stability, for instance if there were more outgoing than incoming water, then the plant will damp off in stages. If this state lasts longer, the tree will die. Moreover, different seasons mean different demands. How much water can bonsai accept? This depends on water amount, air temperature, humidity, sunshine, air circulation and few other aspects. Bear in mind that too much water isn't good for the plant. This causes deficient aeration of soil and lower substrate temperature, which negatively affects the growth process. If streaming continues it might lead to decomposition of roots and entire bonsai later. A young tree with less leafs require less water than old heavily leafed bonsai. Basically, a tree should be watered more during hot days than during cold seasons. This is also necessary when too much sunlight fall on leafs. Bear in mind that every bonsai is independent individuality. As time goes by you will understand requirements of each bonsai from your collection.

Few principles:


  • 1) Check your bonsai everyday,
  • 2) The substrate must not dry up ever,
  • 3) When the soil gets dry, it is necessary to water the bonsai,
  • 4) Do not do watering with cold water. Water from duct has about 5C in the winter, and such temperatures may cause troubles to tropical trees. It is recommended to let the water warm up to room temperature which takes about 8 hours,
  • 5) Do not use hard water. Salts soluble in water increase salts concentration in soil. Carbonates which exist in water may change the soil reaction with the result of modifying nutriments into form unavailable for the plant. The water should not be harder than 12 German degrees. If there is no soft water at your location, you can always use various products for softening. If you live in house, it is recommended to catch the rain water into barrel. Such water is usually soft and acid, and bonsai's prefer it in general. Except some species which require hard and alkaline waters.


Unfortunately there is not enough space for watering inside the pot. That is why you should rather do watering with small watering-can very carefully. In some cases the borders (pot borders) will be watered enough, however the tree could stay dry. Then the soil abstracts from pot borders. These factors may lead to the situation when water flows through the pot walls instead of the substrate. Answer for this problem is really simple; Immerse the entire pot and bonsai into some container and make sure that the whole pot with roots of your bonsai are under water. The result is that air will disappear from the substrate. You will know when this happens once no bubbles come out from the pot and soil.

Big bonsai's usually require watering done few times a day, first time before sunrise and second time after sunset. Really big trees can be watered during the day as well (in my experience you can do so with small trees, but be careful). Leafs should stay dry during the daytime, otherwise they could burn. Generally, leafs could be misted and dusted. If the substrate is wet enough, the water evaporates and it's temperature lowers. You should feel comfortable chill after putting a hand on it.

I hope that these basic advice will help you when watering your bonsai's.
