It was good to read about saving water with self-watering (sub-irrigation) on the Bob Vila website. I am a long time fan of his and remember when he first started on PBS.
It continues to astound me that institutions like the National Gardening Association (NGA) and our botanic gardens don't seem to get it.
Ways to Save Water in Your Garden
There are many simple ways to save water around your garden. Your plants and flowers need not suffer if you are water smart.
Self-watering hanging basket planters are an excellent way to stop water wastage. Not only do these practical style of planters save your water, they also save your time.
Many of these planters only need topping up once or twice a week. The great benefit of these style of pots is that your plants will never suffer from overwatering. There are many styles, sizes and colors to select from.
Although there are a few different ranges to choose from the basic principle remains the same: There is a reservoir of water at the bottom of the container, and when the soil becomes dry, the reservoir tops it up. Self-watering pots can be used for a huge variety of plants, flowers and vegetables, both indoors and out.
