Spring is the busiest season in the landscape supply business — and for good reason. What you do in March and April sets the tone for your entire growing season. Get it right and your yard practically takes care of itself. Skip it and you're fighting weeds, dry soil, and stressed plants all summer.

This guide walks through the exact spring landscaping sequence — from the first yard cleanup to the final layer of mulch — so you can hit the ground running.

Why Timing Matters in Spring Landscaping

Most homeowners think spring prep is something you do "when it feels right." That's a mistake.

The window for effective spring landscaping is narrower than most people realize:

• Too early (February in Kitsap): Soil is waterlogged and compacted. Working wet soil destroys structure.
• Right on time (Mid-March to April): Soil has drained, temps are rising, plants haven't leafed out yet — ideal for mulching, amending, and planting.
• Too late (May and beyond): Weeds have a head start. Mulching now is playing catch-up.

The goal: Be ready before things start growing, not after.

Step 1: Spring Yard Cleanup

Before you add anything to your yard, clear the slate.

What to do: - Rake out dead leaves, matted grass, and winter debris from beds - Cut back ornamental grasses and perennials to 3–4 inches - Remove any winter mulch that was piled around shrubs (it can harbor disease) - Pull any weeds that have already sprouted — easier now than in June

What not to do: - Don't rake lawn turf aggressively until it's actively growing (you'll pull up weak grass) - Don't fertilize yet — wait until the soil temperature hits 55°F

This step takes a few hours but it's the difference between a productive spring season and one where you're constantly reacting.

Step 2: Soil Assessment and Amendment

This is the step most DIYers skip — and it shows.

Test before you add anything. Healthy soil should: - Crumble easily in your hand (not clump like clay or fall apart like sand) - Be dark in color (indicates organic matter) - Have earthworms when you dig a few inches down

If your soil is tired or compacted:

For established garden beds: A 1–2 inch top-dressing of compost, worked lightly into the top layer, is usually enough to refresh them for the season.

For new planting areas or bare spots: Start with quality topsoil. You need at least 6 inches of workable soil for most plants, 12 inches for vegetables.

Harbor Soils tip: Our bulk topsoil and compost blend is available for same-day delivery in Port Orchard and the greater Kitsap area. If you're refreshing multiple beds, ordering in bulk saves significantly over bagged product — and you only pay for what you need.

Step 3: Spring Mulching

Spring mulching is the single highest-impact thing you can do for your landscape — and most people either skip it or do it wrong.

Why mulch in spring (not fall): - Spring mulch suppresses the first flush of weed seeds before they germinate - It locks in soil moisture right when plants need it to establish - It moderates soil temperature as things heat up - It breaks down over the season, feeding your soil

When to mulch: Apply mulch after the soil has warmed slightly — not when it's still cold and wet. In the Pacific Northwest, mid-March to mid-April is the target window.

How much mulch to apply:

More isn't always better. Over 4 inches can prevent water penetration and create a habitat for pests.

Mulch type by application:

The volcano mulch mistake: Do not pile mulch against tree trunks or shrub stems (the "volcano" shape). This traps moisture against the bark, causes rot, and invites disease and pests. Keep mulch 2–3 inches away from all stems and trunks — flat is always right.

Ordering mulch in bulk vs. bags: One cubic yard of bulk mulch covers approximately 100 sq ft at 3 inches deep. A typical residential front bed of 200–300 sq ft needs 2–3 cubic yards. At bulk pricing vs. bagged, you'll pay roughly 60–70% less per cubic yard ordering in bulk — and Harbor Soils delivers to Kitsap County with no minimum.

Step 4: Lawn Prep

Lawns need different treatment than beds, and timing matters here too.

Spring lawn prep sequence: 1. Wait for active growth — don't aerate or overseed until grass is actively growing (soil temp 50–55°F) 2. Dethatch if needed — more than ½ inch of thatch buildup blocks water and nutrients 3. Aerate compacted areas — especially high-traffic zones (core aeration is best) 4. Top-dress with compost — a thin layer (¼–½ inch) raked into the lawn after aeration dramatically improves soil biology 5. Overseed bare patches — spring is the secondary window; fall is better, but spring works for patches 6. First fertilizer application — once grass is actively growing, not before

What not to do in spring: - Don't apply pre-emergent herbicide if you're overseeding — it prevents germination - Don't cut grass too short in the first few mows (keep at 3–3.5 inches)

Step 5: New Planting and Bed Creation

Spring is the best time to install new planting beds or expand existing ones.

Building a new bed from scratch:

1. Kill existing grass/weeds (smother with cardboard + 4 inches of topsoil, or use a sod cutter)
2. Install edging to define the bed
3. Lay 4–6 inches of quality topsoil
4. Amend with 1–2 inches of compost worked in
5. Let it settle for a week before planting if possible
6. Mulch after planting, leaving room around plant stems

Sheet mulching / lasagna method (for new beds without digging): Layer cardboard directly on grass → 4 inches topsoil → 2 inches compost → 3 inches mulch. By fall, the grass underneath has composted and you have a ready-to-plant bed. Great for low-traffic areas or future planting zones.

Calculating Your Material Needs

Use this as a rough guide:

Rule of thumb: 1 cubic yard covers 100 sq ft at 3 inches deep. Divide your square footage by 100 for cubic yards needed.

Frequently Asked Questions

When should I start spring landscaping in Western Washington?
Mid-March to mid-April is the sweet spot for most Kitsap County yards. Wait until the soil has drained from winter rains and is workable — it should crumble, not clump.

How much mulch do I need for spring?
Apply 3 inches as a standard application. Divide your bed square footage by 100 to get cubic yards needed at that depth.

Should I mulch before or after planting?
After. Plant first, then mulch around plants, keeping mulch 2–3 inches away from stems.

Can I mix topsoil and compost together?
Yes — a 50/50 blend of topsoil and compost is excellent for new beds and raised gardens. Harbor Soils sells them separately so you can blend to your ratio, or ask about pre-blended garden mix.

Is it too early to mulch in March?
Not if the soil has drained and you're not mulching over frozen ground. In the Pacific Northwest, March mulching is ideal — you get ahead of weed germination season.
