Personally, I would transplant those babies into some good soil immediately. I have done outdoors many times and this is the method I have always used: I get a few bags of good soil (promix or something similar). I dig a good-sized hole..at least 3 feet deep and 2 feet in diameter. I then line the inside of the hole with some strong clear plastic. Slash a few holes into the plastic to let the excess water drain from the plastic when it's watered. The plastic keeps other plants' roots out of the good soil. Then plant your baby in the hole. You can put some of the regular dirt on top of the good dirt to make it less obvious that there is high quality potting soil there if someone happens to walk by. I then put other various sticks, rocks, dead weeds, ect...ect... on top of the dirt to further conceal the good potting soil and voila!! It looks normal but your baby has some very good dirt to grow strong in. That's what I recommend. That would be far superior to what you have going on right now. Just my thoughts. Good luck and take care. Be safe.
