I highly recommend signing up with Arbor Day Foundation (http://www.arborday.org/) With each membership you get 10 free trees. I’ve been getting flowering trees. They arrive as 18” to 24” twigs, and over 90% of them take root. It takes a few years for them to bloom. Trees can also increase rainfall. We need to start planting trees in the borderlands between areas suitable for farming and dry areas to gradually increase arable land.
In addition trumpet vines and passionflower vines are great host plants for honeybees, butterflys and hummingbirds. They make great fence cover and bloom beautifully throughout most of the summer and fall.
The trees are fine, its the weather that’s the problem this year.
I’ve become a regular Rose of Sharon Johnny Appleseed in my little town. Every year I start a bout a dozen from seed and give them away to neighbors the next spring. They’re great for late season flowers from mid to late July till the first good frost.
