Mulch vs. Rock Landscaping
Mulch is cheaper up front and feeds your soil but needs replacing every year; rock lasts for years with little upkeep but doesn't enrich soil and can overheat roots. For planted beds, mulch usually wins; for low-maintenance borders, drainage areas and around structures, rock is often the smarter pick.
Mulch: Pros & Cons
Pros: Lower up-front cost, insulates roots, retains soil moisture, and breaks down to feed the soil — which planted beds love. It also gives that fresh, finished look every spring.
Cons: It decomposes, so it needs topping up or replacing each year. It can wash out on slopes and, in damp spots, can attract insects if piled against the house.
Rock: Pros & Cons
Pros: Practically permanent, doesn't blow or wash away easily, low maintenance, and excellent for drainage areas, downspout splash zones and bed borders. Great around structures where you don't want organic material.
Cons: Higher up-front cost, doesn't improve soil, retains heat that can stress nearby plants, and is a lot of work to remove if you change the layout later. Weeds and debris that land on top still need clearing.
Cost Over Time
Mulch is cheaper to install but recurs annually. Rock costs more at install but can go many years untouched. Over a long horizon, rock often comes out cheaper — provided you're happy with the layout and won't want to dig it out. The right answer usually mixes both: mulch in the planted beds, rock in the practical zones.

Frequently Asked Questions
Mulch is better for plant health and costs less up front but needs yearly replacing; rock lasts for years with little maintenance but doesn't enrich soil and can overheat roots. It depends on the bed and your goals.
Often yes — it costs more up front but skips the yearly replacement, so over many years it can beat re-mulching each season, as long as you don't change the layout.
