Any info or suggestions welcome, please comment and give me some help with this as im a bit nervous that I will come home in september to find out I wasted my time and money..

well, it's a weed. it should do fine on it's own if you give it a good start. Most important is to till a very nice size hole for the plant(s), as big as you can. Mulch around it so that it won't have to compete with other weeds.
