A professionally designed sprinkler system keeps your lawn and beds perfectly watered — automatically — while saving up to 50% on water versus manual watering.
Manual watering is inefficient — you either overwater (causing fungus and runoff) or underwater (stressing your lawn). A properly designed irrigation system delivers the right amount of water to each zone at the right time, keeping your lawn and landscape healthy with minimal waste.
Green Leaves designs, installs, and maintains irrigation systems for Northern Virginia homeowners. We also service and repair all major sprinkler brands, perform spring startups, and handle fall winterizations (blowouts) to protect your investment through NOVA's freeze cycles.
Modern smart irrigation controllers connect to local weather data and automatically skip watering cycles when rain is forecast or soil moisture is adequate. Clients who upgrade to smart controllers typically see 20–40% reductions in water bills compared to timer-only systems.
We're certified to install and program Rachio, Orbit B-hyve, and Hunter Pro-HC smart controllers. These systems can be monitored and adjusted from your smartphone.
Zone count depends on your property size and the mix of turf vs. bed areas. A typical Northern Virginia home requires 4–8 zones. We calculate exact coverage during our free site assessment.
We recommend blowouts before the first hard freeze, typically mid-October through November in Northern Virginia. Don't wait — burst pipes are costly.
Yes — we service and repair all major brands including Rain Bird, Hunter, Toro, and Orbit regardless of who installed the original system.
Most residential installations (4–6 zones) are completed in one day. Larger properties may require 2 days.
The right timing matters more than the product. Here's the schedule we actually follow across Northern Virginia — based on our zone 7 climate, clay soil, and cool-season lawns.
Most NOVA lawns are cool-season tall fescue, and fescue does almost all of its root-building in fall. The two most valuable feedings are early September and again in late October to early November. A single light feeding in April is fine, but skip heavy nitrogen in summer — it stresses fescue and feeds crabgrass instead of your grass.
Late August through mid-October is the prime window. The soil is still warm enough for fast germination, the nights are cooling, and there's far less weed competition than in spring. Aim to get seed down by mid-September for the strongest fill-in before winter. Spring seeding (March–April) is a distant second and usually gets crowded out by crabgrass.
The main mulch application is mid-to-late spring — April into May — once the soil has warmed and early weeds are cleared. Refresh in fall if beds look thin. Keep mulch 2–3 inches deep and pull it a few inches back from trunks and stems; “mulch volcanoes” piled against bark trap moisture and cause rot.
Wait until after the average last frost — around April 15–20 — before putting out warm-season annuals like petunias, marigolds, and impatiens. Cool-season color such as pansies and violas can go out in late March or again in fall. Perennials, trees, and shrubs establish best planted in fall (September–October) or early spring, and spring bulbs like tulips and daffodils go in the ground in October–November.
Core-aerate cool-season lawns in the fall — September into October — ideally right before overseeding so the seed drops into the holes. Fall aeration relieves the summer compaction that NOVA's heavy clay builds up and sets up thick spring growth. Spring aeration is possible but can open the door to summer weeds.
