Opt for Perennials
Instead of sowing seeds of annual plants routinely, opt for perennials and easy landscaping plants. You will only need to do deadheading and pruning sometimes. Once grown, most of the perennials do well with infrequent watering.
These plants are also quite resistant to pests than annuals. If you would like to grow annuals, grow the ones that are self-seeding and require less care.
