Modern times in the garden
Computer-controlled watering and irrigation systems have also found their way into private gardens. No wonder, they can be programmed beforehand and then work all by themselves. A fully automated system of this kind is admittedly extremely convenient and reliable, but the convenience comes at a price. It is your decision as to whether or not such an investment is really worth it.
The watering can is still up to date
The oldest watering system of all still has its place. With a watering can in your hand you can decide for yourself which parts of your garden you will water, and how much. You can use the rose to direct somewhat less water evenly and gently onto small and delicate plants. Or take off the rose and water with a hard jet and a lot of liquid at once.
However, the watering can has another advantage - and even when compared with watering systems: With bushes and shrubs and vegetables you can specifically wet only the soil and so prevent the water from getting the leaves and forming droplets.
