Black pine seeds in sand
A recent trip to Matsushima Bay in Japan left me wondering if it is possible to grow a Black Pine entirely in sand?
I appreciate something more coarse and porous such as Akadama is more suitable although the Black Pine is well known for being costal and surviving on very little at all. I decided to set up an experiment, some seeds in soil, some in pure sand. Suprisingly ones in sand seem to be much healthier..
In theory sand is a much cleaner substance therefore more likely to be free from infection. I've been finding I have to water very regularly because of the extreme drainage however over watering does not seem to be a problem and I should'nt get root rot - I hope! Watch this space.
Has anybody tried this before?
