Seasonal Landscape Maintenance: A Year-Round Guide

Spring in Iowa is unpredictable, but the work that needs doing is consistent every year. Start with a thorough cleanup of landscape beds. Rake out leaves, pull early weeds, and remove debris that accumulated over winter. Edge your beds to create clean lines between lawn and planting areas. Once the beds are clean, assess what survived winter and what needs replacing.

Prune summer-blooming shrubs before new growth starts. Leave spring-blooming shrubs like lilacs until after they flower. Apply pre-emergent weed control to the lawn before soil temperatures reach 55 degrees. Wait until the soil has warmed up before applying fresh mulch, typically late April or early May in Cedar Falls, Waterloo, and Black Hawk County.

Summer is about keeping up with the growth that spring started. Mow weekly at 3 to 4 inches to encourage deep roots and shade out weeds. Water deeply and less frequently rather than shallow daily watering. Deep watering encourages roots to grow deeper, making your lawn more drought-tolerant.

Monitor for pests and disease. Iowa summers are humid, and fungal diseases can take hold quickly in lawns and ornamentals. Early detection makes treatment more effective. Keep up with weeding in beds, as summer weeds can quickly overtake desirable plants. Deadhead spent blooms on perennials to encourage continued flowering.

Fall is the most important season for Iowa landscapes. The weather is cooperative, and plants are preparing for dormancy. This is the ideal time for lawn aeration and overseeding. Cool-season grasses recover best when seeded in early fall. Apply a fall fertilizer to help the lawn store energy for winter and green up faster in spring.

Clean up fallen leaves regularly. A heavy layer of leaves smothers grass and creates conditions for snow mold over winter. Cut back perennials after frost kills the foliage. Apply a fresh layer of mulch after the ground freezes to insulate plant roots and prevent heaving during freeze-thaw cycles.

Winter in Iowa is hard on landscapes, but you can minimize the damage with some proactive steps. Avoid piling snow on landscape beds or against shrubs when you shovel. The weight can break branches, and de-icing chemicals can damage plants. If you have young trees, wrap the trunks to prevent sunscald and animal damage.

Winter is also a great time to plan next year projects. With the garden dormant and the season slow, you have time to research, get design ideas together, and schedule work for spring. Many contractors book their spring schedule during the winter months, so reaching out early gives you the best chance of getting on the calendar.
