Succulents anyone?

As the environmentally conscious person that I am, I of course chose succulent plants to decorate my front porch and balcony. OK...to be honest, I forget to water my plants, and after killing about 10 different plants which my mom would lovingly plant every time she visited, I thought something that didn't need a lot of water was more my style.

Luckily succulents are available everywhere now, and there are some really beautiful ones that have pink, orange, purple, etc. flowers grow off them. I picked mine up from Target about a year ago, and none of them were larger than 6 inches when I got them...a little smaller than the ones in this picture.

Succulents on my balcony

My goal was to create something cute and pretty like this:

Well look at them NOW! Below are pics of the different varieties I have on my front porch. The problem is, they're growing like crazy and I don't know what to do with them in terms of trimming or re-potting, and because I'm not a plant lady, I forgot to keep those little stick labels that come with them that tell you how to take care of them. So...if anyone that reads my blog, is familiar with succulents, or even has a best guess as to what I should do with these, please let me know. :)

Above Pic: This one is the perfect size for the pot, although the smaller plant falling down the edges doesn't seem to have room to spread. PS. The big plant is PRICKLY at the tips of the leaves and along the edges.

Above Pic: The plant in the pot closest to you is fuzzy and starting to grow some beautiful orange flowers BUT it's busting at the seams. I feel like I'm going to walk outside one day and find the plant busted through the pot, and the pot shattered into pieces.

Above Pic: The BEAST. This is the biggest pot, so naturally it has the most plants. Most of them are growing at, what seems to be, a normal rate, but the one in the back is out of control. Do I trim it, take it out, feed it to a lion?

Any advice welcome!
