it looks as though you have 2 plants in one pot is that true. if so loosen the dirt up and see if you can get the root ball out and put them in separate pots. get bigger pots like 5 gal pots and bury the stem of the plants about 2 inches from the 1st set of leaves. then prop them up with a bambo stick or something, so when u do set them outside and the wind hits them they wont break. when you do or if you do transplant them water them down ( the soil) with superthrive 1/4tsp to a gallon of distilled water.
