Loss of a Green Thumb

I used to have a green thumb. I mean it! I would plant things and they would miraculously grow to be the most beautiful plants in the world. I won gardening contests! Now it seems to be slowly fading away...maybe because I am in an apartment and can only practice my talent in potted plants and the plants seem to not agree with this plan. See my attempt below. Its green but the flowers have yet to sprout!

Ideas or words of encouragement welcome! Also we have to put it up high a skunk tried to eat our plants!
