>>2734042>is grafting hard or not in your experience?NTA but it isn't that hard, follow a tutorial/book/video to the letter and you'll get it right, the hardest part is doing cuts so they fit just right (there are special knives and tool for this job), then it's just checking on it every now and then.
I recommend starting with something you don't care that much about because your failure rate will probably be pretty high initially.
>Keep in mind the soil is incredibly bad and hardAutumn olive is used specifically to restore degraded soil, thrives in bad conditions, it has berries similar to red currant both in looks and taste, grows pretty tall and wide, good hedge plant.
Goumi berry isn't as good for degraded soils but berries are much better in my opinion, doesn't grow that big, usually around 3 meters, might be better if you don't want a massive hedge.
Sea buckthorn is also good in degraded soil, especially contaminated by salt, very high salt tolerance but it grows better in sandy soil than heavy soil, very thorny and needs full sun.
All those are nitrogen fixers.
Roses thrive in heavy soils btw.
>I heard you can reproduce plums from seed, but for others, like pears and apples, I'd need cuttings, am I correct?Yes, this is correct, you need to graft those cuttings into a rootstock.
>I tried rooting some cuttings but was too absent lately to keep an eye on them and water them regularlySome plants are really hard to root from cuttings, air layering is your final resort if nothing else works.
>I translated and looked into what you mentionedI could recommend a few more things but I don't know which USDA zone you are in or how much rainfall you get.
If you have any Southish facing wall I recommend grapevine on a trellis right in front of it, they grow fantastically when they are partially protected by a home or a shed and only take space vertically.
