The beauty of succulents is they store water in their leaves-so they can have a drink whenever they want.That is why you don't need to water them that much. Depending on where you live, just 1 time a week is plenty. Make sure to water less in winter, when the plants are actually dormant. Too much water can cause them to rot--so during on-going heavy rains, protect them from the rain. A house eave would do nicely.
Unlike their cousin the cactus, succulents like filtered light, they can burn if left exposed to Hawaii's strong, direct sunlight all day. Partial direct sun here in Hawaii is best.
