I have some succulant plants. "Hens and Chicks" and some Jade. I was wondering what kind of plant food to give them? Do they need a special kind of soil, like cactus potting soil?

They don't really need any special fertilizer. I would recommend whatever you use, use it at half strength (or less). They want a well drained soil. My Grandmother always had these growing in her rock gardens, and didn't do anything special for them. Good luck.
