why are my tomato plant stems purple instead of green on my starts? West Jordan, Utah
Submitted by dimondfamily

The purple coloration on stems of your tomatoes could be an indication of a phosphorus deficiency. There may actually be plenty of phosphorus in the soil, but it may be unavailable to the plant at low temperatures. It's a relatively common problem, and often corrects itself as temperatures warm up.
