I am a reformed plant killer here to say you can have plants that thrive. My sister is a Master Gardener and has helped me along the way. She used to give me plants and say "You can't kill this" and of course I did.
Indoor plants don't like to be repotted so choose a container just a little bit bigger than the one it was in. Stick your finger in the dirt, it should be dry to first knuckle (1 inch?) before you water again. Fertilize once a month or so. Watch to see if yellow leaves at bottom = too much water. Dead leaves on top = too little water. Gently spread out the roots, press the plant down slightly, put dirt around plant to the same depth as before, and make sure you don't have air pockets around the roots. Put dirt in a little at a time. Use good quality potting soil.
Outdoor veggies that are easy...tomatoes, chives, lettuce, spinach, green beans, strawberries, herbs. Everything but green beans can be planted in pots or buckets also.
I have already planted onions, carrots, lettuce, spinach in Iowa. I will plant green beans and tomatoes in May. Google when to plant in your area or call your extension office.
Strawberries just do their own thing so I don't have to do anything to them. They also spread like crazy, so plan on ripping the runners out if they go where you don't want them. I even canned strawberries for the first time last year. When I opened the jar it smelled like heaven.
