Choose drought-tolerant plants
If you’re likely to be away from home regularly, it’s worth choosing plants that tolerate neglect. Cacti and succulents are a good choice, as they're adapted to dry conditions. Mother-in-law’s-tongue, cycads, palms and anthuriums will also cope without water for two or three weeks. In general, plants in small pots dry out more quickly, so buy larger specimens. Alternatively, grow several small plants in a large decorative bowl, as this will retain water for longer.
