Every spring I plant my tomato plants and then they turn yellow at the bottom what is with this?

Everyone has an opinion about tomato plants because everyone grows them, so you will probably get a lot of answers to this.





If just a few of the lower leaves get yellow, but you have good fruit production and the rest of the plant is a healthy green, I wouldn't worry about it.





It might be due to too much water. Mature tomato plants almost don't need any water. They send roots down very deeply - sometimes more than three feet - so they usually find all the water they need. In very hot climates, of course, more watering is necessary.





Other possibilities might be too much fertilizer. If the leaves are yellow but the leaf veins are green, it might be clorosis (use chelated iron/zinc fertilizer to correct). But, I doubt either one of those.





Cut back on the water and fertilizer and see if that makes a difference. As long as everything else about the plants is OK, though, a couple of yellow leaves are not important.

don't over water that could be the problem if the leaves are only yellow on the bottom
Reply:molybedenum or nitrogene deficiency usually. However, if you've fertilized with a multimineral fertiliser the problem could be too much nitrogen! If too much nitro is problem you will get heaps of leaves but not much fruit. Use a slow release fertiliser containing the m,icronutrients and also lots of organic compost.
