apples are incredibly easy to grow from seed. A bag of sand mixed with seeds in the fridge and a few months BAM! youve got apples. Some might say you will only get a good apple every 1000 trees or soo. I think this is all in how you look at it. Apple trees have incredible ecological value amazing wood and are useful in soo many ways ie processing into jam, jelly, apple butter, cider, preserves, drying, sauce ,desserts, juice and just eating. They are home to many a insect and provide shade and food for deer birds racoons possums and people alike. My suggestion is find one you like, grow some out and guerrilla plant them anywhere ...they will most likely share qualities of there parents and may be sweet or have incredible disease resistance ..the possibilities with apple is endless. I grow several out every year and plant them around my neighbourhood ..this year im growing kazahkstan apples from the cornell university seed bank. try it out!
