Watering systems are becoming more popular each year too. They not only conserve water in the garden, but allow the gardener to maintain optimum growing conditions all season. Types of systems include trickle or drip which applies small amounts of water at the base of each plant. Soaker hoses are effective in shrub beds or close-planted row crops. Timer clocks are also available to turn the water on and off on a regular schedule.
Water systems are also available for indoor plants as well.
These include the wick method that allows water to be absorbed from a container below the potted plant. I have also seen some new and interesting types of water cans. Some have longer spouts to reach into groups of plants. Others are designed with a wand and flexible tubing to water hanging baskets without taking them down. Watering and fertilizer always seem to go hand in hand, so look for one of the many types of fertilizers that are available.
