Oops! My error...this tree is not quite 4-1/2 months old. I will correct this info above.
I grow my obesums in community trays and when the first true leaves appear, I begin a weekly alternating regimen of a weak solution of liquid rooting hormone and a weak solution of fish emulsion/seaweed fertilizer.
In the picture, note the seedling that has a stick placed next to it. This seedling ramified very early...it is the subject plant in this post.
Then at 2 months old I transplant into their own individual pots...for this batch I used 5" pots and had mixed a little bit of CRF into the media.
The plant has been growing outdoors exposed to some sun and rain...shaded mid-day by coconut fronds overhead. The media is kept moist...if no rain for a couple of days, then it is hand-watered.
