Yesterday I sent 6 packages:
I would just sow them in a good moist soil and wait 20 to 90 days for them to sprout (64ºF to 86ºF, 18ºC to 30ºC), in the shade; no summer sun when small, good water if possible (rain, acid), or without chlorine; use acid soil with sphagnum moss or river peat with nice forest leaves or so, garden soil, something that drains well like perlite or vermiculite, some organic matter ... I would later add manure, not when I sow. Never let it dry.
For jaboticabas, eugenias, campomanesias, psidium, Annona sylvatica, etc. (rainforest species):
Be very careful with the direct sun in summer or when it is very hot, get accustomed to the shade and never lack water. They could take full sun when taller than 2 feet or 60cm or so, before that, use morning sun or half shade (not too hot from the afternoon heat). Psidium and Campomanesias would support more sun, but take care: if they dont like your soil and/or dont have enought watering, they will suffer with more sun.
Cheers!
