June is the pivotal month in the Portland-Metro yard calendar. The rains are tapering off, soil temperatures are rising, and the long dry stretch is just around the corner. What you do -- or don't do -- in June has a direct impact on how your lawn and landscape hold up through July and August.
1. Start Your Irrigation System (or Make a Watering Plan)
If you have an in-ground irrigation system, June is when you should be running every zone, checking heads, and confirming your controller schedule is set for summer. If you're hand-watering or using hose-end sprinklers, decide now which areas get priority and how often -- and set a reminder so it actually happens.
2. Raise Your Mower Deck for Summer
Switch your mower to 3.5-4 inches before summer heat arrives. This is the single most impactful thing you can do for a cool-season lawn in Oregon. Taller grass shades its own roots, retains moisture, and handles summer stress dramatically better than a short-cut lawn.
3. Apply Mulch to All Planting Beds
If you haven't mulched your beds yet, June is your last good window before the soil bakes dry. A 2-3 inch layer of bark dust or wood chip mulch cuts moisture evaporation significantly, suppresses weeds, and keeps root zones cooler through the hot months.
4. Deadhead and Prune Spring Bloomers
Rhododendrons, azaleas, and other spring-flowering shrubs are done blooming by June — this is the right time to deadhead spent flowers and do any shaping. Don't wait until fall; pruning now gives shrubs the whole season to set next year's buds.
5. Treat for Weeds Before They Set Seed
June is peak weed growth in the Portland metro. Getting on top of weeds now — before they flower and set seed — breaks the cycle. One dandelion going to seed can produce 150–200 seeds. Hand-pull or spot-treat, and edge your lawn to prevent grass from creeping into beds.
6. Plan or Book Any Summer Construction Projects
Summer is prime season for hardscape work — patios, retaining walls, pathways, and fencing. If you've been thinking about a project, June is the time to call and get on a contractor's schedule. By July, most landscape contractors are booked weeks to months out.
7. Check for Drainage Issues Before They're Forgotten
It's tempting to ignore drainage problems once the rain stops. Don't. June is ideal for assessing where water was pooling, which downspouts need extensions, or where a French drain is needed — while the evidence is fresh. Schedule repairs now for next rainy season.
