There are many things we could say about watering bonsai. I tried a couple of times in this blog mention some of them. Some are difficult to make sense of the words, but as I’m always willing to try. This is watering newly replanted trees.

In post-transplant time we need to be up at a speed change, it is that the mass of the interior floor (the part was returned to the pot) can dry much faster than it seems.

  • If the inner area is full of fine roots, quickly dry up after transplantation.


This pine is beginning to develop a solid mass of soil and roots, and this is the area we are going to take our moisture “read” when decide when to water. Once dry, you will see a very light color compared to the new surrounding soil.

If all the fine roots of transplant your tree is cut, shame on you, but that’s a different matter. For the sake of this example, we assume you have fine roots, and we’re talking simply of trees established with a solid mass of roots and soil. There are a myriad of other situations, such as the proto-root balls with fibrous roots that still hold the soil together, but these pictures show what we are hoping and working toward.

Especially with conifers, which usually do not prune the branches while transplanting. And so …

  • In bonsai transplant refined, we have created a situation where fewer roots will be supplying the same need for higher water.

This inner mass we’re talking about, this is the area to be monitored to determine when to water. Ignore, for a few weeks, at least, to take his reading of new soil moisture is decided about the original mass. No active roots in the new soil and still not dry quickly.

  • Another thing to keep in mind when transplanting is to keep a part of this old mass floor exposed, not covered with new soil, so you can see when dry .

In many cases, you will be watering when the soil is still wet again. So we ignore that area. Again, I’m just commenting irrigation structures bonsai repotting with the more mature root.

  • In summary, read-only moisture level, where there are roots to determine when to water.

prolix publication. The hope that some of it made sense!
