That is what they say. The best time to plant fruit trees was 10 years ago! lol (Though... sounds like 20yrs would be even better!)I planted about 15 semi dwarf fruit tress in 1981, they are in their prime. Trees I planted in 2000/2001 are just starting to have great production. Peach trees are amazing.
It does give me something to look forward to down the road. So far I have planted (as far as fruit goes) 2 peaches, 2 plums, 4 mulberries, 1 pear, and 1 fig... with 4 more figs going in soon, 2 high-bush blueberries (Will be pruned under 8ft tall for better production/easy picking), and 4 clusters of artichoke mounds in between for added privacy. The rest I planted were just ornamental for the front/side yard areas to raise curb appeal.
I made sure to get trees that are resistant to the diseases in my area... and made sure that their fruit ripens in staggered succession so as to have a solid flow of fruit vs a tsunami. Self-pollination for all as well except the pear.
I have plans/room for much much more. Next year I will likely get some Paw Paw fruit and Persimmons. Then come back and plant more in the understory of all the trees as they grow. I would not mind having a lot more blueberries, raspberries, etc.
My son eats over $100 worth of fruit every week or so. lol
