I got a spider plant from a lady in my area. They started in water. I planted them in normal planting soil. Then when they were getting a bit over grown I split them and gave half to my sister and I kept the other half. Both slowly turned brown at the tips, but didn’t fully die. I ended up taking mine out of the dirt and cleaned it off and put it In the top of my fish tank. I saw a few videos saying that it is great for them. But both hers and mine are turning brown at the tips still. Mine has lessened in size since I put it in the water from mainly pulling dried leaves off before placing it In the water. They both get indirect light and mine has a plant light as well for the fishtank plants. I’m not sure what to do since they both live in different environments but still turn brown slowly..
