Should I remove old mulch before adding new mulch? This seemingly simple question can elicit a multitude of considerations, especially for avid gardeners and landscaping enthusiasts. On one hand, the presence of aged mulch might present a barrier to the pristine aesthetic and functional advantages of fresh mulch. Yet, could the decomposition of the old material contribute beneficial organic matter to the soil beneath? What about the potential for harboring pests or diseases within the decaying remnants? Doesn’t the idea of layering new mulch over old pose risks of suffocating emerging plants by limiting essential air circulation? Conversely, would the removal process itself disrupt established roots or cause soil erosion? With such diverse factors impacting the decision-making process, how should one weigh the pros and cons? Isn’t it essential to ensure that each layer of mulch serves not only an artistic purpose but also reinforces the sustainability of the garden ecosystem? Ultimately, what truly governs this perplexing dilemma?
