When I get one that’s substantially better than the older one. For my purposes I am breeding to a strict show standard meaning that type/structure is of utmost importance, second is eggs, third is meat. Ultimately the whole package is being selected for in every generation.
If I have an older...
Five trays of freeze dried goodies.
Habanero peppers is the top and part of the second tray. The purple is red cabbage, the white is yellow onions, the orange, green, yellow and red is sweet peppers, the slightly pinkish stuff on the bottom far left is eggplant.
