Indoor vs.outdoor

I had moderate luck with my outdoor garden last year, but some of the melons and vegetables just didn't want to grow like they should . Of course you know I will be trying the same things this year, but the question I keep asking myself is maybe somethings will do better in an indoor garden! I feel as if I may need to change the watering system in the outdoor garden, and use more fertilizer in the soil. Then I think about just going indoors, and not worry about soil at all. There is plenty of room outside for everything I want to grow, but limited space indoors. Indoor gardens have less disease and insects, and use less water, but I will lose to much space. Oh what to do! Lucky for me I have a little more time to plan.The greenhouse and raised garden beds are empty now, but hopefully soon they will be overly abundant with vegetables and herbs!
