Wow! I’m very impressed with your garden description.
I also like to give stuff away...especially the extra seedlings. I have a big give-away (the ones I don't use) in early April and all my friends and family get to take some plants home. I usually give away at least 100 tomato and pepper plants...so...I can indirectly provide food for many people.
AND I plant all heirloom...so I seed save. I've got a years worth of seeds saved and another 4 years of selected varieties vacuume sealed.
