What is the pressure for foundation plantings & turf?

• A. 400-500 psi at 6-10 gpm.
• B. 100-200 psi at 2-4 gpm.
• C. 600-700 psi at 12-15 gpm.
• D. 50-100 psi at 1-2 gpm.

Answer: (A)

For foundation plantings and turf, the spray setup is chosen to deliver enough volume and fine enough droplets to cover dense turf and the plant surfaces around buildings. Using a higher pressure with a substantial flow rate helps atomize the spray into droplets that spread evenly across both the turf blades and the plant foliage, improving coverage and uptake. The 400-500 psi range with 6-10 gpm provides the right balance: it produces a spray pattern and droplet size suitable for thorough, uniform application over large, uneven surfaces, while still delivering enough volume to cover the area efficiently. Lower pressures and smaller flow (like 50-100 psi at 1-2 gpm) would not provide adequate coverage on turf and foundation plantings, and even higher pressures with much larger flows aren’t typically needed and can lead to inefficiency.
