get another container the same size and fill it with dirt like the other one and put the first pot on top of the second, try to cut the bottom of the first one off to btw. your plant is telling you it needs more root room and if you dont listen to her in a couple weeks or so growth will come to a crawl as the roots all bind up(rootbound)and nutrient and water intake is effected. next time transplant sooner or use bigger containers or something. have any pics of the plant and your setup?
