I would like to plant some avocado trees in my garden. The soil seems very stony (<3cm in diameter stones on average, but a couple of bigger ones) and they go down at least 30 cm.
Do I need to do anything to the soil in preparation for the fruit tree? Will it be okay with the stony soil or should I remove the stones within a certain distance?
The research I have done mainly talks about removing stones from flower beds but not bigger plants like trees.
The tree is about 1m tall and was home-grown by my dad. He lives in another part of the country but there are simmilar soil conditions there. There are other avocado plants in the area. A neighbour has a couple too, I believe. I live in Swellendam, South Africa. This is a map of the soil in the country:
I live in the bottom left province where the soil conditions are mostly red and green:
