Last year I counted 40 "new" trees on the property that had nothing to do with me. Olive, almond carrasca, pine.. I'm looking at what I spent on purchased starts like cherry, it really is a dismal hit rate and learnt in first season not to buy anything from nurseries.
I'd consider year old starts, but my overriding observation is to start from seed, the most practical, least costly. Just need patience, but it looks like from seed, a sapling will soon enough overtake a 3-5 year old nursery bought sapling and be very robust.. What's your experience on that front?
I've got a couple of Queensland bottle trees to take from seed, same requirement as olive, and in third year its looking positive,, but I can't get a pear that cost me €15 to produce for love nor money growing in a groasis box, another option that promised much but same issue, if it isnt started in the right spot a new tree aint working even if water is not an issue.
Keep going, I guess.
