I have some young Papaya trees i grew from seeds, they currently are 6"tall witht their first 6 leaves showing. I plan on growing them in pots for now, they are in 1 gallon in a nutrient rich well drained soil. I would like to know if/when/how often i should be fertilizing. Possible fertilizer recommendations. Has anyone used "superthrive" before? I am in zone 10, i always read FULL sun, is it ok for young plants to go bone dry in the hot sun in between watering? I really appreciate all and any help.
