Early Girl.......blossom end is yellow, rest of the tomato is red and ripe, but with a very hard core center. What could be the cause?

hard white core in tomatoes NEW
by: GEORGIE

I canned 80 lbs of tomatoes this year all with the infamous hard white core.
The explanations shown here do not suffice. These tomatoes were purchased at a local produce market.
My home grown tomatoes also have the same problem. What is happening? I have been canning and preserving tomatoes for over 50 years and have never seen the problem like this. I find it very suspicious!

Hard Core Tomatoes
by: Madeline

Looks like Mother Nature solved my problems, after weeks of throwing tomatoes away. Actually they looked like they were ripening on the outside, but not the inside. Since our weather has changed they have ripened all the way through. Tomatoes are delicious. Thanks for all your comments.

Hard core occurs under stressful conditions
by: Clark

According to the Kansas State University Research and Extension unit, tomato fruit often develop a tough white core in the center under stress conditions.

During stressful weather--usually aggravated by excessive fertilization--this central core becomes tough and turns greenish white. The walls also may become pale and corky.

You can't control the weather, but keep your tomato fertilization within the recommended amounts, and try to avoid extremes in soil moisture. Good luck!
