The most important rule for watering succulents is this: Only water when the soil in the succulents' growing container is bone dry. We repeat, let the soil dry out completely between waterings. If the soil isn't crumbly, dry dirt, don't water it. See, most houseplants want their soil moist at all times.
A light feeding of manure tea, diluted fish emulsion, or a balanced fertilizer (15-15-15) help succulents grow lush and lovely. Be sure to dilute concentrated liquid fertilizers. Not doing so risks damaging roots. For container-grown succulents, use one Moo Poo tea bag per three gallons of water, steeped overnight.
Your succulents do not like either overexposure or underexposure to sunlight. They prefer a moderate amount of sun exposure. It's safe to give them from 6-8 hours of filtered sunlight everyday, except when the temperatures outside is too hot then full or partial shade is recommended.
In general, succulents and cacti do best in temperatures ranging from 40-80°F. While minor sways in temperature outside of this range are tolerable, sways of 5° or more can cause irreversible damage.
Squeeze the sides of your succulent's plastic pot to loosen its soil, and gently remove it from the pot. Gently crumble away any clinging dirt from your succulent's roots. Place your succulent in its new pot, then add more soil to the top to secure your succulent in place.
