It might be a drip irrigation not sprinkler because a sprinkler will always thros water to certain distance. I understand your point without watering on leaves one can use soaker hose, but drip also suitable or a wate spike in this way.
Thanks for the advice and your tips are excellent. I would agree with you for the plants that need water to the roots, but if you go such as Mint, leafy vegetables, then make sure we need to use Sprinkler in order to avoid pests.
What is the size of yoru garden, so I can take a look that will suit for your Garden. I would also like to know how many plants are their and in which condition. I mean whether directly in Soil or in Pots.
From the pressure the insects will run far away even it is easy to remove when we runs the sprinkler. Plants loves to have Sprinkler just like rain and even the dust can easily cleaned day by day.
Sprinler sprays water on the plants and it covers in 360 degree type so Sprinkler can remove any insects if plants get infected. Did you ever watched a video on YouTube about sprinkler and Rain gun?
