Well friends here I go again with questions. The tomato plant was NOT given to me,but I bought this at the food store and this morning I noticed the yellow leaves. I think I know the reason,as I checked the moisture with meter and it was dry,but I'll still ask you experts. Thanks ed yellow leaves ( photo / image / picture from Edlou8181's Garden ) ( photo / image / picture from Edlou8181's Garden )
If just the leaves on the bottom are turning yellow, it could mean that the plant isn't getting enough nutrients or not a lot of sunlight. I would try moving it out into the sun and giving it a bit of fertilizer.
Kens advice is good. Since you got it at the food store, it probably also hasn't been hardened off (gradually introduced to the joy of living outdoors). Try giving it morning sun, afternoon shade for a few days, gradually increasing the time in the sun until you can just leave it in one spot where it gets the most sun. A gentle fertilizing won't hurt--perhaps half strength? And the bottom leaves of tomatoes are the oldest leaves, and old age gets to all of us (ahem ). They may be yellowing because they're old (unlike some of us who turn white topside).
Both are correct Ed. If it was dry, water it well and let it soak a bit. Then allow it to drain. That potting soil will not hold water like plain old dirt will. So if you just pour the water on it,,most will run right through. Just set it in a pan for an hour or so and then water it. The pan will catch the excess and it will soak it up in short order. It will also help that plant to add some epsom salts by mixing it with the potting mix on the surface before watering !! About a teaspoon or two would help it.
