Hi guys. I need help on how to plant a couple cattails in my pond. I got two plants for free but now have no idea what to put them in and how to put them in my pond. Can I submerge them completely? I'm going to have to because I can't put them on the side, they will fall over. What kind of pot do I need? Soil? How do I keep the soil from coming out of the pond? I know cattails spread like crazy, so you don't have to tell me that part, lol. I'm trying to look online, but so far I have no found any good info. Also I don't know what type of cattails they are. Thank you!
