Cache-You probably need to keep track of what you have planted but I must admit to liking the "what did I plant here" questions later on.
Watering on top spreads problems from leaf to leaf and if possible you need to avoid. One thing I have found is it is impossible to have too much sun for tomatoes. So direct sun, watering at ground level instead of sprinkling on top, rotate physical locations, and clean up everything as you go.
I also believe in soil preparation. Quite a bit of natural fertilizer if you can find it otherwise 13-13-13 in heavy doses in early October to get ready for next year. Be sure you test soil for correct Ph level and add Lime. Till it in.....repeat After Thanksgiving Day.
I am always amazed at what the no-till folks accomplish. I understand the need but my results are actually not so good
I have a daughter who is hyper-allergic to Epsom Salt so I cannot use that
