they like a ton of organic matter (well rotted).
its hard to over-fertilize them.
they like water, but it has to be well draining.
lots of sun and heat, the more the better.
root-rot + over watering is the #1 killer.
compost around the base, then mulch on top works great.
rabbit and chicken waste, or fish emulsion are good fertilizers.
roots dont like to be disturbed, plant in-place if possible.
(or use a peat-based container) then cut the bottom when planting out.
