Hi.. welcome to the site. So im assuming you planted a good sized pup from someones parent plant? If not, and your plant is small.. it may struggle with afternoon sun. Many new plants are grown in pots and dappled sun for a few weeks at least, and then planted out.. the best planting site would allow for morning and early noon sun, but shade in the hottest part of the day. We dont all have that ideal stup available, so use what you have.
As far as water, you will likely need some sort of irrigation, unless you are getting regular rain.. our summer has been pretty dry here on the Gulf coast, so ive been running irrigation to mine daily. Doing that by hand will be alot of work! Misting your plant with a hose or bottle during the hottest part of the day can help it a bit also.
I fertilize my mature plants, (6ft of stem) with 4oz of 13-13-13 every week during the grow season. You can do it monthly (1lb) but i feel our sandy soil leeches nutrients fast, so i prefer weekly feeding. I also heavily mulch with woodchips, and grass clipping when i have them.
As far as the plant surviving in your zone, i would talk to the person you got it from and see what they do.. if they got fruit, even if it took 4 years, they are doing something right! Good luck, and post up some photos of your plant!
