and with out a picture hard to say. I had a Century Blue Agave. It was way too big for me. To help stop or slow down the growth, I planted it in a smaller pot, used a sharp knife to slice thru the roots, and all the pups, reducing their growth capacity and used regular top soil to fill in the pot. That thing still over grew it's pot and always cut me up when I moved it. I wore heavy winter shirt with welder's gloves. Some help here. Mine was about 3 ft. by 4 ft. wide and had to move it inside for the winters here. With that clay soil, the plant was at the 50 lb. mark. So glad I found a home for it. I also used finger nail clippers to cut the very tip off each leaf. It's not noticeable and keeps it from doing damage to you. Just have to watch out for the spines on the sides of the leaves.
