I have a question for anyone with experience keeping foxtails. I have had no luck with them at all. I want to know if Im doing something wrong. Foxtails are supposed to be easy plants to grow. My foxtails lose their needles or leaves if you will. All Im left with is stems after about a week or two. I have co2 injection in a 55 gallon tank and my other plants, wisterias are growing like crazy. I have to keep trimming them back often they grow so fast. why wont my foxtails survive? I also add iron and other liquid nutrients every 3 days.
