Welcome Sean! Apples are probably the most forgiving fruit for grafting. I had a few grafts fail this year, but it was my first time trying and I didn’t know the omega style grafting tools were not very effective. I’d recommend reading through the guide I put together: Beginner Grafting Guide. Feel free to message me with any questions but applenut will be an infinitely more experienced resource with his experience growing in warm regions. I would highly recommend searching the forum for low chill apple varieties. That is likely your biggest challenge once you get pruning methods under control with applenut’s guidance.
