I've been trying to propagate a small feijoa tree I have (usually grown in New Zealand) that's in a pot. I'm in the UK. I've read online supposedly the best methods to propagate this tree and have attempted them the last couple of years, however, after trying at least 50 cuttings with each of the following methods and getting zero results, I've had zero success, so I need some help.
I've tried cuttings with and without rooting hormone, cuttings with fresh green shoots, cuttings with older harder wood and cuttings from 1 year of growth. I've tried cuttings stripping the lower inch outer layer back, and without, trying cuttings with and without rooting hormone in soil, sand, wood chips or just in a glass jar with water. None have produced any roots at all. All attempts were made between from April-September during the main plant growing period. I've tried 3 different brands of rooting hormone in case the first and second were bad or something.
There's not been any fruit for me to grow from seed yet but the tree is only 4-5 years old so I believe it should produce something within the next couple of years, it appears like it might be my only option at this point once it does though.
Does anyone have any tips please? This is one of the only plants I'm really struggling to reproduce, and most people online say it's one of the easiest!
