Day 17- 1st Timers Gardening

My kiddo brought home a tomato plant yesterday from school. I love that they are learning to grow their own food and be healthy and what not but however I did not plan on becoming a green thumb. Needless to say I have tried this and killed everything besides a cactus, and that took me leaving it behind at an old house for 2 months before it decided to grow! (Now its a pretty good size and its thriving in our new homes' garden> yes my husband went back when the new people were moving in and got out looking like a crazy with a hammer in hand marching towards the front of the house to dig it up but hey we got it back!) lol Anyways back to the new gardening I am going to have to do now that my kid has started to grow tomatoes!!! Being that my parents live across the street I tried to pawn the plant off on them to add to their already growing abundance of plants! But no they insisted they give me this topsy turvy garden planter to start our own and this is how it all started...... I now have this huge black boxy thing on my back patio with one tiny little 6" plant sprouting from the underside! Now what? Sun and water I know but what else? I figured that we would try and get some additional plants like peppers, jalapenos, and some fresh herbs would be nice. But for now its just our one lonely little plant. Its a start for some old fashioned home made salsa!!! Can't wait... FYI if you know any tips feel free to leave em in the comments! :)
