|I planted red tomatoes of four different varieties and they are all ripening orange. Why?
|You have asked an interesting question. In the first place, do make sure they are fully ripe because color does tend to be at its peak when the fruits are just ready. Next, although we think of tomatoes as being "red" and most of the tomato varieties we see in the produce section at the grocery store do seem to be pretty "red", there are actually many variations on that color in the tomato world. Catalog descriptions begin to touch on this by calling the fruit "bright red", "deep red", "redder color", "scarlet" and so on. When we look at "heirloom" tomatoes, the variety is even broader and then of course there are the so-called orange, yellow and pink varieties as well. In the meantime I hope your tomatoes taste good.
