NOTE: Corn Cold Testing As an additional service to our customers, all Johnny's treated sweet corn seed lots are "cold tested". We take this extra step to ensure our customers receive the highest germinating seeds possible. Cold testing mimics spring soil conditions and indicates suitability for early, cool soil sowing. FOR PACKAGE SIZES OF 5 LB. AND LARGER, SEED LOTS THAT GERMINATE BELOW OUR STANDARD IN THE COLD TEST ARE NEVER SHIPPED WITHOUT PRIOR CONSENT OF THE CUSTOMER.
