Why are my tomatos not ripening this year?

Question

It is odd I have lots of green tomatos, but they are just not turning red like they normally do. Have you ever heard of such a thing?

Answer 1

It has probably been too cold and wet. They need lots of sun and heat.

Answer 2

How about fertilizing them with a heavy phosphorus-laden compound?  Phosphorus helps promote bloom and fruit development.  Look for anything sold as a "bloom booster"

This is assuming all other requirements are met:  enough sun, enough moisture and no viral infections in the plant.

Answer 3

Sounds like they are not getting enough sun. They need full sun. Maybe your weather has been too rainy or cloudy?

Answer 4

Are you 100% sure that the tomato that you planted is a red variety?  I got some "beefsteak" tomato plants this year that actually turned out to be a green variety.  They stay green even when ripe.

As a side note, the green variety seems to be much sweeter and less acidic--just in case you decide that you want to try them next year.
