We are thinking of buying a garden sprinkler for our backyard. During summer, the heat of the sun can dry up the leaves of newly planted vegetables and our recourse now is to put a little shade to lessen the heat. But we also think that if the surroundings are wet then the heat will be somewhat bearable to the plants. What we have in mind is a sprinkler that is small and can be placed in a corner.
If you have a limited number (and area) of plants or shrubs to water, then a drip line is the better option in comparison to a regular sprinkler. Drip lines use less water, water plants more effectively, and they're easy enough to make automatic. Soaker hoses are another option, and they're pretty similar to drip lines albeit a bit faster. Adding some shade can help, but most plants and vegetables and whatnot require eight hours of direct sunlight each day, so that can cause issues.
A drip system is a good system as the water is watering the root system. A sprinkler system is watering the air and just may cause the plant to burn a little.
We don't have a sprinkler system installed in our back garden, but we did have a hose installed, which is connected to a faucet that is built into the wall in our dining room. That was installed earlier on this year, and we have been using it to water the plants, as well as other things, like hose down toys that may have been left outside and are dirty.
