I found a sad pot of LB about 6 years ago by a dumpster, it was mostly brown and had 1 section of green, the pot it's in was strange to me, the top section holds about 3" of soil and the bottom is the water reserve, I never transplanted it and over the years I've just added some potting soil, I noticed the other day this section turning brown, my question is, should I re-pot it into a pot with just soil or leave it be and just add more soil?? I've added a little Miracle Grow plant food to the water. Whats your advice, Thank You my fellow plant lovers. I did cut off the yellow section this morning.
