I will commit to planting 100 trees on my 10 acres in the Mojave Desert, California, over the next cool 5 months. My small team and I planted 120 here trees in 2016. So 100 is doable. Only planted about 20 trees a year since then.
Last year three owls moved into my little 11 year old forest of tall windbreak trees windward of the veg garden. My trees are getting noticed!
I bought 19 potted trees last week, mostly from a community College Ag Dept sale, many desert natives and 8 are nitrogen fixing.
The other 81 trees I will start from seeds and cuttings. I've been collecting tree seeds as I see them as I drive by. I hire a strong teenager to dig the 24" holes below the caliche level. I start cuttings in their permanent hole in the soil using a rooting hormone and a mycorrhizal innoculant blend. Each new tree in the ground gets a cylinder of rabbit wire around it and 2 dripline emitters. We elevate the driplines on stakes or tree cylinders to a height the rabbits can't reach. They just get to nibble off low branches that stick out through the wires.
I start the tree seeds in the house and move them out to the solar heated, non-freezing greenhouse when they get too crowded in here. We will transplant them outside in late winter.
I'm just starting to get into Russian olives for nitrogen fixing and evergreen windbreaks. I've seen only 3 of them locally and there's no evidence of their spreading or being invasive around here. They take our extremes of temp, high winds, alkaline soil and salty well water. I harvested handfuls of mature seeds last week by the rosdside and will see if I can get them to sprout.
