would outdoor plants survive without care?

Use guano or other time release ferts. Dont stress it is very possible can you tell us more about your situation.

I have nearly 500 bag seeds from all over the north east NJ/NY/MA/Canada. I have a good location to plant them back at my house (right next to a pond but since im in a dorm at college right now I wont be able to care for them much until I get out mid May. I'd like to be able to harvest at least a dry LB or more by the end of August / Early September. Should I add those water crystals and fertilizer when I plant some seeds in a few weeks? If I plant 50 seeds what are my odd's of a few surviving nicely on their own before I can care for them mid May?
