I am moving from California to New York City for a year and none of my outdoor bonsai are going to be able to join me on this adventure. While I am there, I was hoping to store my favorite trees at my parents house. They are gardeners but have never looked after bonsai before.
I have maybe 10 trees that I will want to keep down there and can hook them up to automated watering. However, the automated watering never seems to work perfectly for bonsai that are in small pots with bonsai soil because some trees need less water and others need more. In order to try to compensate for that, I was going to plant them into deeper planters with normal soil (similar to planting in the ground) and have automated watering hooked up to those. I also plan to purchase an outdoor Nest camera (or similar camera) to watch and make sure it doesn’t turn into a disaster or that the watering malfunctions for days at a time.
The trees are all less than 2-3 feet tall. A photo of the the planter I am planning on using is attached.
Has anybody tried this before? Any recommendations or can you foresee any potential pitfalls?
