here is an elegant solution in the form of self watering containers. The principle is simple. Rather than having a hole in the bottom of the pot, there is instead a reservoir of water. Potting soil is suspended above the water reservoir by means of a perforated barrier. Circular "wicking chambers" reach down into the reservoir and draw water up to the plant's roots.
Lazy gardening refers to the use of simple techniques in agriculture or gardening that nonetheless give good results. Lazy gardening is a commonly used term, but it could be easily called "effortless gardening", "efficient gardening" or "no-fuss gardening". The key is that rather than doing unnecessary work (or planning for work which never gets done, leading to poor results), you get the best results for the effort you put in, through making use of natural processes and wise strategic choices.
