Homeowners typically use commercial “patch and repair” products to seed bare or damaged lawn areas in the spring. Commercial products typically contain inert matter, fertilizer, and turfgrass seed, which is dominated by perennial ryegrass (Lolium perenne L.) and tall fescue [Festuca arundinacea Schreb.; syn. Schedonorus arundinaceus (Schreb.) Dumort., nom. cons.] mixtures, with a few fine fescues (Festuca spp.). Our objective was to assess the establishment potential of low‐cost patch and repair ingredients in the spring that include low‐input fine fescues. Field experiments were initiated in Indiana and Oregon in April 2019 to investigate seven mulch ingredient treatments and two starter fertilizer treatments. All treatments included the same fine fescue seed mixture. All mulch ingredients, including the untreated (no mulch) control, eventually reached a similar turf cover; however, the rate of establishment was influenced by the mulch ingredient. Conversely, starter fertilizer had a minimal impact on the establishment rates but increased final turf cover. Compost‐derived mulch consistently resulted in faster turf establishment, which was generally ≥6 d sooner than other mulch options, with the exception of potting soil, no mulch, and, at times, topsoil, which may provide similar results. The results indicate if the newly seeded area is adequately irrigated, then neither mulch ingredient nor starter fertilizer may be necessary, thus providing more financial savings for consumers. The results also indicate there are multiple financially feasible options for homemade patch and repair ingredients for homeowners and lawn professionals to use in the establishment of low‐input turfgrasses from seed.

用种子和修补混合物从种子中形成低投入的草皮草：覆盖物和起始肥

房主通常在春季使用商业“修补和修复”产品为裸露或受损的草坪区域播种。商业产品通常包含惰性物质，肥料和草皮草种子，主要由多年生黑麦草（Lolium perenne L.）和高羊茅（Festuca arundinacea Schreb。）主导。同步 Schedonorus arundinaceus（Schreb。）Dumort。，nom。缺点]混合物，并有一些精美的羊茅（Festucaspp。）。我们的目标是评估春季低价修补和修复成分（包括低投入细羊茅）的建立潜力。2019年4月在印第安纳州和俄勒冈州启动了田间试验，以调查7种地膜成分处理和2种入门肥料处理方法。所有处理均包括相同的细羊茅种子混合物。所有覆盖物成分，包括未处理（无覆盖物）对照，最终都达到了相似的草皮覆盖率；但是，覆盖率受覆盖成分的影响。相反，发酵剂肥料对定植率的影响最小，但最终草皮覆盖率增加。堆肥导致的覆盖始终能够加快草皮的形成速度，通常比其他覆盖方案早≥6 d，但盆栽土壤，无覆盖以及有时 表土，可能会提供相似的结果。结果表明，如果新播种的区域得到了充分的灌溉，那么覆盖物成分和起始肥料都可能不是必需的，从而为消费者节省了更多的资金。结果还表明，对于房主和草坪专业人士而言，自制修补剂和修复剂有多种经济上可行的选择，可用于从种子中建立低投入的草皮草。
