| The stems on my Tomato plants are turning a brownish color, but the leaves look very healthy. Is there something wrong? I also have them in my Topsy Turvey and the stems are also a brownish color. I thought it might have been from the sponge being dirty from the soil. Is that what's causing this? |
| If the plants are growing - putting out new leaves and stems, it might be a little sunscald or it could be just a natural process of maturation. The stems never actually develop bark but they do grow a thicker tissue on the outside of the stem that helps support the upper part of the plant. As long as new growth is being produced, your plants are just fine. |
