Critical Issues to Fix FIRST

MOWING HEIGHT IS WAY TOO LOW
Your mower at setting "2" is cutting around 2 inches. Tall fescue needs 3.5 - 4 inches. This is the #1 reason your lawn is thin. Raise your mower to the highest setting TODAY. This single change will dramatically improve thickness, weed suppression, drought tolerance, and root depth.
SOIL TEST IS 4 YEARS OLD
Your University of Delaware test was sampled April 2022. They recommended retesting in 2-3 years. You need a fresh test from University of Maryland Extension before the fall overseeding push. Cost: ~$20. This determines every product and quantity we use. Update (May 2026): a new UMD Extension test has been submitted -- results pending.
PARKING ON THE LAWN
Every time you park on the grass, you compact the soil and crush grass crowns. Compacted soil = shallow roots, poor drainage, thin grass. Minimize this as much as possible. Core aeration in fall will help reverse the damage.
THE GOOD NEWS
Your soil lead is safe. You have a decent grass base to work with. The yard gets enough sun for fescue. And you're in Zone 7a -- one of the best zones in the country for cool-season lawns. This is very fixable.

Progress Log

Dated check-ins on what's actually happening vs. the plan. Newest first -- add a new block each time you make progress.

Update -- May 31, 2026 Late Spring
MOWING -- HEIGHT IS COMING UP (GOOD)
Cut Fri May 29 from ~5" down to 4" -- right move, and it respects the 1/3 rule. Grass is growing fast right now, so the next mow lands around Mon/Tue (Jun 1-2).
...BUT HOLD AT 3.5-4", DON'T DROP TO 3"
You mentioned dialing in to ~3". Keep it at 3.5-4" -- and heading into June heat, run the highest setting (4"). Three inches is below target for fescue and will stress the lawn as summer hits (remember, the #1 problem we started with was mowing too low). Taller grass = cooler soil, deeper roots, fewer weeds.
SOIL TEST -- SUBMITTED, AWAITING RESULTS
The new UMD Extension test is in and results are expected back shortly. A couple of decisions are on hold until it lands: the fertilizer choice (especially phosphorus) and the exact lime rate. When it arrives, update the fertilizer + lime lines and the pH in Key Numbers.
FERTILIZER -- DON'T PUT DOWN BOTH BAGS
You have 2 bags on hand and haven't applied them yet -- good place to pause. Maryland's Lawn Fertilizer Law matters here: (1) you need a soil test before applying any phosphorus to an established lawn -- use a P-free formula (middle number 0) unless the test shows a P deficiency; and (2) nitrogen is capped at 0.9 lb N per 1,000 sq ft per application (min 20% slow-release N). Two bags across ~2,800 sq ft is almost certainly a double dose -- burn risk and over the legal N rate.

Recommendation: wait the few days for your soil test, then apply one bag at the labeled rate of a slow-release product. If you must feed sooner, use a P-free slow-release N -- note Milorganite (6-4-0) contains P, so it's not the right pre-test choice.
BROADLEAF WEED KILLER (HOSE-END) -- GOOD TO SPRAY NOW
Your hose-end broadleaf killer (Weed B Gon-type) is fine to use now. Best practice: spot-treat the weeds you can see instead of blanketing the lawn; spray on a calm day under ~85°F with no rain expected for 24 hrs; and don't mow for about 2 days before and after so there's leaf surface to absorb it and time to move it down to the roots. Since your next mow is due Mon/Tue, either spray today and mow Wed+, or mow first and spray a couple days later. (No conflict with fall seeding -- just finish broadleaf spraying at least ~4 weeks before the September overseed.)

Month-by-Month Action Plan (2026-2027)

April 2026 (NOW) Spring
Raise mower to highest setting (3.5-4")
Do this before your next mow. Never cut more than 1/3 of the blade at a time. If the lawn is currently at 2", raise to 3" this mow, then 4" next mow.
Apply pre-emergent herbicide for crabgrass
Soil temps are hitting 55°F in Silver Spring right now. This is the window. Apply NOW -- every day you wait, more crabgrass seeds germinate.
Product: Scotts Halts Crabgrass Preventer OR Prodiamine 65 WDG (pro option). For 2,800 sq ft: ~1 bag of Scotts Halts.
Submit a new soil test
Contact University of Maryland Extension Soil Testing Lab. Collect samples from 10-15 spots across the front lawn, 4" deep, mix together, and submit.
Cost: ~$15-20. Phone: (301) 405-1349 or search "UMD soil testing lab"
Spot-treat visible broadleaf weeds
Don't blanket spray -- just hit the weeds you can see (dandelions, clover, plantain). Use a pump sprayer or hose-end sprayer.
Product: Ortho Weed B Gon (hose-end) or Triclopyr concentrate for tough weeds. ~$12-15
Clean up debris and rake out dead material
Light raking to remove leaf litter and matted dead grass. Don't power rake -- just clean the surface so sunlight reaches the soil.
May 2026 Spring
Light fertilizer application (optional) -- wait for the soil test
Your test is in and due back any day -- best to wait for it. If the results show deficiencies, apply a light dose to match. If you feed before the test, use a P-free slow-release (MD law requires a soil test before applying phosphorus to an established lawn) at no more than 0.9 lb N / 1,000 sq ft -- one bag, not two.
Product: P-free slow-release lawn fertilizer (middle number 0, ≥20% slow-release N). For 2,800 sq ft: ~1 bag. ~$20-25
Begin consistent mowing schedule
Mow weekly at 3.5-4 inches. Leave clippings on the lawn (grasscycling) -- they return nitrogen and organic matter to the soil.
Sharpen mower blade
Dull blades tear grass instead of cutting it, leaving brown tips and inviting disease. Sharpen or replace the blade. ~$10-15 at a hardware store.
Trim hedges
Give the road-side hedge a shaping trim. Cut the top flat and sides at a slight angle (wider at bottom than top) so sunlight reaches the lower branches.
June 2026 Summer
Start deep watering routine
Water 1 inch per week total, in 1-2 deep sessions (not daily light sprinkles). Water early morning (6-9 AM). Put a tuna can in the yard to measure -- stop when it fills up.
Tip: Buy a simple hose timer (~$25) to avoid forgetting the sprinkler is running.
Raise mow height to MAX (4 inches)
Summer stress is real for fescue in MD. Taller grass = cooler soil, deeper roots, more shade on the ground. DO NOT scalp.
Optional summer feed -- after the soil test, P-free, 1 bag max
Hold until the soil test is back. Under MD law you need a soil test before applying any phosphorus to an established lawn, so use a P-free slow-release (middle number 0) unless the test shows a P deficiency. Cap nitrogen at 0.9 lb N / 1,000 sq ft per application -- about one bag at the label rate for your yard, never two. Milorganite (6-4-0) is slow-release but contains P, so save it for when/if the test calls for phosphorus.
Product: P-free slow-release lawn fertilizer (e.g., 24-0-x with ≥20% slow-release N). 1 bag for 2,800 sq ft. ~$20-25
July - August 2026 Summer Survival
Keep watering consistently
This is when fescue wants to go dormant. Keep up 1" per week. If you can't water, it's okay to let it go dormant (brown) -- it will recover in fall. But don't go back and forth.
DO NOT fertilize
No fertilizer in July-August heat. It forces growth when the plant is stressed, inviting fungal disease.
Order seed and supplies for fall
Don't wait until September -- good seed sells out. Order by mid-August.
Seed: Jonathan Green Black Beauty Ultra (shade tolerant fescue) or Barenbrug RTF (self-repairing fescue). ~$40-60 for 7 lbs (covers 2,800 sq ft overseeding rate).
Schedule core aeration for early September
Call a local landscaper or rent an aerator from Home Depot. Book early -- September is peak season and slots fill up.
Pro aeration: ~$75-150 for front yard. Rental: ~$80-100/day (more work, but cheaper if you split with a neighbor).
September 2026 -- THE MONEY MONTH Fall Push
THIS IS THE MOST IMPORTANT MONTH OF THE YEAR
Cool-season grass does 80% of its growing in fall. Everything we've done leads to this. Soil temps drop below 70°F, nights cool off, rain picks up. This is when fescue WANTS to grow.
WEEK 1 (Labor Day): Core aerate the entire lawn
Make 2-3 passes with the aerator. Focus extra passes on the area where you park -- that soil is the most compacted. Leave the plugs on the surface -- they'll break down.
Hire a pro or rent a core aerator from Home Depot. NOT a spike aerator -- must be hollow-tine core.
WEEK 1-2: Overseed with quality TTTF blend
Immediately after aeration. Use a broadcast spreader at the overseeding rate on the bag (usually ~4-6 lbs per 1,000 sq ft for overseeding). Seed needs soil contact -- the aeration holes are perfect for this.
Seed: Jonathan Green Black Beauty Ultra or Barenbrug RTF. For 2,800 sq ft at 5 lbs/1000: ~14 lbs needed. ~$60-80
WEEK 1-2: Apply starter fertilizer
High phosphorus to promote root development in new seedlings. Apply same day as seeding or within a few days.
Product: Scotts Starter Lawn Food (24-25-4) or Jonathan Green Green-Up Starter. 1 bag covers 2,800 sq ft. ~$25
WEEKS 2-4: Water new seed daily
Keep the top 1" of soil consistently moist (not soaked). Light watering 2x per day for the first 2-3 weeks. After germination (7-14 days), reduce to once daily. After 3-4 weeks, transition back to deep, infrequent watering.
Consider a hose timer with multiple zones. Orbit or Melnor brands. ~$25-35
Apply lime (based on soil test results)
Your 2022 test recommended 25 lbs ground limestone per 1,000 sq ft. Update based on new test. Apply after seeding -- lime doesn't interfere with germination. For 2,800 sq ft: ~70 lbs of pelletized lime.
Product: Pelletized dolomitic lime (Pennington Fast Acting Lime or equivalent). 2 bags (40 lbs each). ~$12-15
October 2026 Fall
Second fertilizer application
Switch to a balanced or high-nitrogen fertilizer now that seedlings are established (4+ weeks after germination). This feeds the existing lawn and new grass.
Product: Milorganite or a 24-0-11 type fertilizer (as your 2022 soil test recommended). ~$15-20
First mow of new grass
Once new seedlings reach 4-4.5 inches, mow to 3.5 inches. Use a sharp blade and mow when the grass is dry. Don't mow when it's wet -- you'll pull up seedlings.
Keep leaves off the lawn
That big tree will drop leaves. Don't let them smother new grass. Mulch-mow light leaf cover, but bag or rake heavy accumulation.
November 2026 Late Fall
Winterizer fertilizer application
This is the MOST IMPORTANT fertilizer app of the year. Apply a high-nitrogen slow-release fertilizer. The grass stores this energy in its roots for winter and uses it for explosive spring green-up.
Product: Scotts WinterGuard (32-0-10) or equivalent high-N winterizer. 1 bag for 2,800 sq ft. ~$25
Final mow of the season
Drop height slightly to 3 inches for the last mow. This prevents snow mold and matting over winter. Only do this for the LAST mow.
Clear all leaves from lawn
Don't leave a mat of leaves over winter. It smothers the grass and promotes fungal disease. Mulch-mow or rake.
December 2026 - February 2027 Winter Dormancy
Leave the lawn alone
The grass is dormant but the roots are still active underground. Don't walk on frozen grass -- it damages the crowns. Avoid parking on it in winter.
Service your mower
Sharpen blade, replace air filter, fresh battery charge (electric). Be ready for spring.
Plan for spring pre-emergent
Order pre-emergent in January/February so you're ready when soil temps hit 55°F (usually mid-March in Silver Spring). Note: if you overseeded in fall, you CAN apply pre-emergent the following spring as long as the new grass has been mowed 3+ times.
March - April 2027 -- The Payoff Year 2 Spring
THIS IS WHEN YOU'LL SEE THE TRANSFORMATION
If you followed the fall program, the lawn will green up thick and dense. The winterizer fertilizer stored in the roots will fuel explosive spring growth. Neighbors will notice.
Apply pre-emergent (split app: round 1)
When soil temps hit 55°F (mid-March). Use Prodiamine (Barricade) at the split-app rate -- you'll apply the second half 6-8 weeks later for season-long crabgrass control.
Product: Prodiamine 65 WDG (pro grade, lasts longer than Scotts). ~$25 for a jar that lasts years.
Resume mowing at 3.5-4 inches
The lawn should be thick enough now that you're mowing regularly. Keep the blade sharp.
Submit soil test #2
Test again to see how pH and nutrients responded to lime and fertilizer applications. Adjust your program based on results.
Assess and celebrate
Compare photos from April 2026 to April 2027. The difference should be dramatic. Adjust the plan for year 2 based on what worked.

The Mowing Rules (Non-Negotiable)

Height: 3.5 - 4 inches

Always. No exceptions. Taller grass shades out weeds, holds moisture, and develops deeper roots. Your setting should be 4 or the highest available.

1/3 Rule

Never remove more than 1/3 of the grass blade in a single mow. If grass is 6 inches tall, cut to 4 inches. If you've been away and it's long, do 2 mows spaced 3-4 days apart.

Sharp Blade

Sharpen every 20-25 hours of mowing (roughly monthly during peak season). Dull blades tear the grass, leaving brown tips and inviting disease.

Leave Clippings

Grasscycling returns nitrogen and organic matter. The clippings DON'T cause thatch -- that's a myth. Only bag if you're mulch-mowing heavy leaves.

Mow When Dry

Wet grass clumps, cuts unevenly, and can spread fungal disease. Mow in the late afternoon when morning dew has dried.

Vary Your Pattern

Alternate mowing direction each time (N-S, then E-W, then diagonal). This prevents ruts and helps the grass stand upright.

Watering Guide (Hose + Sprinkler Strategy)

Since you don't have in-ground irrigation, here's how to make the hose + sprinkler work:

SeasonAmountFrequencyMethod
Spring (Apr-May) 1 inch/week 1-2x per week Supplement rain only. Check weather first.
Summer (Jun-Aug) 1-1.5 inch/week 2x per week, deep Early morning (6-9 AM). Use tuna can to measure.
Fall - Seeding (Sept) Keep moist 2x per day, light 5-10 min sessions to keep seed bed moist for 3 weeks.
Fall - Established (Oct-Nov) 1 inch/week 1x per week Reduce as temps drop. Stop when growth stops.
THE TUNA CAN TRICK
Put an empty tuna can (or cat food can) in the sprinkler zone. Run the sprinkler and time how long it takes to fill 1 inch. That's your watering duration. Most oscillating sprinklers take 45-90 minutes to deliver 1 inch.

Hedge Maintenance (Minimal Plan)

You said just maintain them. Here's the bare minimum to keep them healthy:

Trim 2x per year
Late May/June: Shape after spring growth flush. Late August/September: Light trim before winter. Cut the top flat and sides slightly angled (wider at bottom) so lower branches get light. This helps fill in those bare spots at the bottom over time.
Fertilize once in spring
Sprinkle some of the same balanced fertilizer you use on the lawn around the hedge base in April/May. Not critical but helps.
Mulch the base
Add 2-3 inches of hardwood mulch around the hedge base (where you have that barrel planter area). Keep mulch a few inches away from the stems. Suppresses weeds, retains moisture, looks clean.
