Bonsai Tree Question
Hi. On inspecting the soil in my Bonsai tree pot today (which was rather hard and dry, even with daily watering), I discovered several small stones/pieces of grit. What is the purpose of these stones? I removed some of the bigger ones and turned the surface of the soil over a little, before watering again. My Bonsai is a Podocarpus. Many thanks.
Bonsai Direct says:
This is a great question. Bonsai like a free draining soil. The grit is added to the compost to open the soil so that more air can get to the roots.
This encourages the small fibrous feeder roots which all bonsai growers are looking to develop.
The grit also helps prevent the bonsai becoming over-watered , although it does sound as though in your case this is not an issue , it may be getting close to the time that it needs repotting. If the soil is hard and dry i would recommend watering by standing the bonsai in a sink with a few inches of water in it, for about 10 mins. This will re-wet the soil and make it easier for you to water.
I hope this helps
