@SleepyLizard ___ - Where do you live that apples and avocados grow in the same place? I have properties in southern, central and northern California, Pennsylvania, upstate NY, and Japan. I have been spending most of my time in Japan for the past few decades. So.Cal. Property: 34.36045472N, 119.04488173W – look just north of the house. ;) Chance for cross pollination is low and that is a typical avocado orchard on the west coast. Not sure how they do it where you are… pollination by gator maybe? You can see a few I started from seed there on our property. Apple and avocado trees can grow and produce fruit in many MANY locations throughout the world - most of California for that matter - you might not get orchard grade yields but plenty to enjoy on the kitchen table or maybe share with neighbors every year. _ - Johnny appleseed was planting apples for hard cider not for eating. "The Johnny Appleseed", "Albemarle Pippins" apple was/is primarily used in pies, tarts, and applesauce - not cider. That was a rumor started by one of his famous detractors - a journalist (LOL) named Mike Pollan (or Pollen?). He arrived at that conclusion simply because J.A. (Mr. Chapman) advocated *_AGAINST_* grafting. _ - Golden delicious, Granny Smith, etc are cultivars not species. All cultivars of apple are the same species K… _ - Google "US Plant Patent Number 139" and tell me if the Hass avocado which grew from seed was patented or not. Not, and your lawyers should know that – no matter how some corporate suits have twisted the language: 35 U.S.C. 161 Plant Patents: "Whoever invents or discovers and asexually reproduces any distinct and new variety of plant, including cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber propagated plant or a plant found in an uncultivated state, may obtain a patent therefor, subject to the conditions and requirements of this title." If it was grown from a seed it’s not patentable. “As noted in the last paragraph of the statute, the plant patent must also satisfy the general requirements of patentability. The subject matter of the application would be a plant which is developed or discovered by the inventor, and which has been found stable by asexual reproduction. To be patentable, it is also required:... “ Bla bla bla... _ - I grow in zone 10b and I have no brand of avocado. k. _ - Do you really think knowledge about US Agriculture patent law should be common knowledge? 🤣 Yes. Or educate yourself adequately if otherwise - it's not rocket science. _ - Avocado groves are not planted all one cultivar (again you incorrectly refer to cultivars as "species"). If you knew anything about avocados you'd know their flowering behavior requires a mix of cultivars for good pollination and now farmer in his right mind would plant all of one type. I showed you otherwise above but who the hell is talking an orchardist? The claims you made were that you can’t start an Avocado or Apple tree from seed and reasonably expect it to produce eatable fruit – and that is patently false!!! Given the proper soil, climate, and care it’s nearly 100% success rate! "While many avocado trees will self-pollinate, they will fruit better if cross pollinated with a different type." Www dot gardeningknowhow dot com/edible/fruits/avocado/pollinating-avocado-trees dot htm bottom of the article. And the difference can be negligible. My 12 YO tree here in Japan (35.22136193N 136.89394395E) produced about 150 avocados last year and all I did was feed it. That’s enough… I don’t need it to produce 250 like an orchardist might want or expect. _ - You cannot graft avocado cuttings to other species such as citrus. Grafting has to be done within species. I already told you that you could. Just saying “no you can’t” doesn’t qualify as a legitimate argument. I’ve seen it 1st hand myself. At one California home I have an avocado scion on a tangerine root-stock which is why I made the comment I did. Here’s a quote from Wiki: “Grafting between species of the same genus is sometimes successful. Grafting has a low success rate when performed with plants in the same family but in different genera. And grafting between different families is rare” No use of the words “impossible” or “cannot” there. ;) Oh ye of little faith! _ - Look up root rot and tell me what would happen if you flooded avocados. You get a buttload of avocados! I flood my Japanese fruit trees (including the Avocado tree) once every ten days for about a month and a half. What you’re talking about is doing so in a soil-bed that can’t or doesn’t drain well. That’s called incompetence or in the best case ignorance! _ I think the only thing your experience as an old man has taught you is that you confidently say things about topics other people don't know about so you're not used to being challenged. I’ve also learned it’s sometimes impossible to argue with someone who thinks they already know everything. Seems to me you’re just butt-hurt someone is calling you out. You can indeed plant avocados from seed and get good fruit and large quantities for a home gardener and likely a hundred or more people in your chat have so claimed. I am just another one of such. It works and I encourage others to try it as well. If you live in the climate and have the space, give it a go – in 5 to 10 years you will happy you did. Avocado is low maintenance high yield. Nice nice nice! _ We've come to the point of this interaction where you're going to delete your comment in shame. Shame that a fellow American refuses to learn something they think they already know everything about, maybe huh? Although… florida-man, so perhaps a very different "cultivar"? :p
