Arbor day foundation has some great deals on trees if you can wait a few years for the payoff. We have a weed ridden embankment that is filled with weeds that no one knows what to do with. I joined the foundation and will receive 10 flowering trees that I will use to turn this space into something special. The trees are shipped via FedEx for free and look like a stick, but in a few months you will see some pretty leaves and in a few years you will have a legitimate tree. It's an investment into our future and for 10 dollars why would you not plant as many trees anywhere that has the capacity?
