Growing Joshua Trees from Seeds, Years 8-9

I can't believe it's been 9 years already! This is by far my longest running plant growing series. In this update I cover the two big risks I undertook in the past year: 1) transplanting to a much bigger volume of coco coir in a self-watering planter, and 2) adding Epsom salt (magnesium sulfate) to my chemical fertilizer regimen. So far the Joshua tree seems to have responded very well to all changes I have thrown at it. The growth acceleration in the full sun environment of the last two years is very apparent in this episode.
