Roselee,

See links to special types of stationary deflection-plate heads that control droplet size and throw larger droplets:

Hope this helps you in the direction of what you are searching for. Let us know how it all turns out. JMHO Aloha

Thank you so much. I've been out of town, but now that I'm back I'll check it and let you know.

It seems the heads in the link provided are for systems with low water pressure. My problem is the opposite. I have a lot of water pressure which probably promotes the very fine spray, especially if the heads are adjusted so they cover a small area without extending their reach to wet the sidewalks and street.

Rosealee,

yes, you would have to reduce pressure to optimum which is 15 psi. You would have to step your pressure down and match pressure and flow rate to the heads in the flower beds. It is not that difficult. Several in-line pressure reducers would do the trick. These deflection-plate type of heads are also affected by very windy conditions. Why not go drip tape? That is the best system to counter windy conditions. The drip type also would require reducing the water system pressure for the flower beds only 15 to 25 psi. What is your current water pressure and flow rate per zone? Aloha

You may want to consider using shrub sprinklers. They provide lower to the ground water spray.
