My 200 carrots this all grew only 2" long and 1" in diameter!!!!

These are Sugarsnax, I have growned them many years and they were nice and long and almost perfect.

I have used the same seeds from the constainer that I bought 4 years ago, these are pelleted type seeds, I have great germination. The previous years the same container carrot seeds produced great carrots.

We had a lot of rain this year. I also added about 3 inches of spagnum peat moss, and tilled it in this year. I have never added spagnum peat moss before to my soil.

The carrot was hard/woody.

PH is 6.8. Live in Pennsylvania.

Any comments what could have horribly went worng?
