Here are some clever prod­ucts that can save you time and help re­duce water us­age.

Rain sen­sors, com­bined sen­sors and tem­per­a­ture sen­sors shut off ir­ri­ga­tion sys­tems when rain falls. You can also buy so­lar-pow­ered wa­ter­ing units. Water rings are plas­tic rings that help re­tain water around the root zone of plants to pre­vent run-off. Water bags are UV-treated and hold 25L of water, enough to water a sapling for up to 30 days. Self-wa­ter­ing pots have a reser­voir in the bot­tom of the pot to hold water (right). The soil soaks up the water from be­low, so as long as the reser­voir is kept full, your plants can ac­cess mois­ture.
