Answer: Not in my opinion! Compost is terrific stuff. It adds organic matter to the soil, improves drainage in clay soils, improves water and fertilizer retention in sandy soils, provides nutrients, increases soil microbial activity, and encourages earthworms. I like to incorporate compost into the soil before planting, but I also use it as a mulch or top dressing. It will act as a great mulch/top dressing for your existing flowers and over time break down and improve your soil. As it ages, some of the nutrients in compost will leach away, but compost is generally not extremely high in nutrients anyway. It will still provide many benefits for your soil no matter when you use it. Most vegetables and flowers are heavy "feeders" and can deplete the soil's fertility fairly quickly. Adding compost will prevent that. I hope this info helps!
