@Evan: "I am scheduled to go back to college in the fall at a community college here in Minnesota for a 2 year associates degree in Horticulture. "
Who's schedule is this?....Is it self-imposed strictly due to wanting to continue the career or as a means to temporarily defer student loan payment? I don't mean this in any cutting way, but it is an option that many choose even if not really the best advice. Personally, I would not advise this, especially with a $70,000.00 noose around your neck.
My advice would be first and foremost to get yourself into a situation to buy down that debt. In many instances, that would mean selling your soul and maybe even your first born to
boot, but I think given your location and even point of development in your life, you may be able to keep one leg in the
permie world while maximizing the buy-down of your debt. Again, just MHO, but do not add further to that debt in any way, shape, or form.
Rochester, MN is one of the wealthiest cities in the US per capita. Make that work in your favor. Either get a job that pays directly from the Mayo Clinic system, or one that indirectly takes advantage of that capital. If you are presently working in landscaping and wish to maximize your income from that venture, see if you can work yourself into higher-paying gigs of this nature that service Clinic grounds or those who benefit highly from those salaries.....homes of employees and vested interests of the medical center. Live as cheaply as possible and put as much money as you can afford towards the loan. (And don't discount doing something with your music major: A
city with money will have more disposable income for arts ventures than one without, so you may be able to find a way to offer either lessons or involvement in the planning/performance of musical events that come with at least a moderate price tag.)
At the same time, learn as much as you can from your current landscape employer and keep your eyes open to the many permie-oriented establishments in the Rochester area that themselves take great advantage of the wealthy population in the that city. (Don't get me wrong, it's a two way street....the citizens get better food than they would otherwise and the permie crowd gets financially compensated to stay afloat.) One example that you may use for future reference is the Oak Center General Store (and Gardens):

And for it's size, Rochester has a good number of Food Coops and ancillary support:

There is also an alternative
energy non-profit that you may try to work your way into:

There will likely be much more, but just the ones that come to mind.... Good luck!
