I'm going to buy some Magda kousa F1 squash this year, because they're so good and I want to share them with a friend.
Except for some impulse purchases last summer when I had cash on hand in the store, I haven't bought a seed for years. Between the MMM bonuses and Nicky's swap I had many things to grow, and I grew and saved seed to swap from many more things which kept me going.
Saving and swapping seed has been a huge experience for me. Every kind of seed has it's own requirement and shucking techniques... very time intensive but totally worth it for the learning and also of course, any time you have more time than money.
I can't believe how expensive seed has become! Holy cow.
Seed saving is a must know for hard times.
