Lawn Care & Mowing in Wilmington & New Castle County
Union Park Landscaping provides weekly mowing and full-season lawn programs across New Castle County: sharp-blade mowing with clean lines, edging and blow-off every visit, plus fertilization, weed control, aeration, and overseeding timed to Delaware's cool-season grass calendar.
A great Delaware lawn is mostly about doing the right things at the right times — feeding in fall, pre-emergent in early spring, seeding in September. We run that calendar for you so the lawn just keeps getting thicker.
Your lawn is asking for help if…
- It's more crabgrass and clover than actual grass
- Bare patches reappear every summer in the same spots
- The soil is so compacted water runs off instead of soaking in
- Mowing keeps getting skipped and the yard shows it
- It greens up late and browns out early
How we work
- Lawn assessment. We look at grass type, thatch, compaction, shade, and weeds, then recommend only what your lawn actually needs.
- Season-long program. Applications and services are scheduled to Delaware's growing calendar — you don't have to remember anything.
- Consistent crews. Same crew, same day each week where possible, with clean stripes and no clumps left behind.
Built for Delaware conditions
New Castle County lawns are overwhelmingly tall fescue — a cool-season grass that thrives in our spring and fall and suffers in July heat. That's why fall (September–October) aeration and overseeding is the single highest-impact lawn service in Delaware, and why we front-load feeding in fall rather than dumping nitrogen in summer.
What it costs
Weekly mowing for typical New Castle County lots runs $45–$75 per visit. Full-season fertilization and weed-control programs typically run $350–$700 per year. Quotes are free.
Lawn Care questions, answered
How much does lawn mowing cost in Wilmington, DE?
Most New Castle County homes pay $45–$75 per weekly mowing visit, including edging and blow-off. Larger or heavily fenced lots run more. Season fertilization programs typically add $350–$700 per year.
When should I aerate and overseed in Delaware?
September to mid-October. Soil is warm, air is cooling, and weed pressure is fading — tall fescue seeded then establishes before winter and survives the following summer far better than spring-seeded grass.
How short should grass be cut in Delaware?
Tall fescue should be mowed at 3–4 inches, higher in summer heat. Cutting shorter stresses the grass and invites crabgrass — it's the most common DIY lawn mistake we see.
Do you offer one-time mowing or only contracts?
We prioritize weekly customers, but we take one-time and vacation cuts when the schedule allows. No long-term contracts — we keep customers by doing good work, not paperwork.
