Hi All! So I had this idea while thinking about ways to first of all improve my own watering but also in case I was going away for the weeknd something and had to leave the watering to someone trusted but who didn’t have a full bonsai watering skill set.
The idea is to make a colour spectrum/chart showing the different colours of a typical Akadama soil relative to its dryness/wetness. I’m aware that a lot of people use other substrates. But all my trees have Akadama and when i personally check my soil I look at the colour of the Akadama “pebbles”. The darker the more wet - the lighter the drier. (As Jonas has also mentioned in his latest blog post on watering decidious trees).
So I’m wondering wether it’s possible making a colour chat maybe in 10 differently grades displaying the wetness/dryness and from that you would be able to tell when it’s time to water?
Please don’t be afraid to shoot the idea down, but in my head it could work on short term basis?
What do you think?
