Under extreme fire conditions, all plants will burn. Spacing and density can be more crucial than what species is planted. Firewise Zone 1 is the house to 5 feet: nothing flammable next to the house, including trees, brush, tall grass, leaves, firewood piles, and bark mulch. Zone 2 is 5 to 10 feet: well-kept lawn; avoid evergreens that catch fire easily; any trees at least 10 feet from the house; 10 to 15 feet between tree crowns. Zone 3 is 10 to 30 feet: thin vegetation out to at least 30 feet; on a slope, extend clearing and thinning to 100 feet on the downhill side. Evergreen trees, if used, should be kept 30 feet from the home in Zone 3. Evergreen shrubs should not be used within 5 feet of the house or out buildings (Zone 1). Ornamental grasses should be planted no closer than Zones 2 or 3 or beyond. Flammability ratings are the result of the authors’ experience and that of others (VL / L / M / H / VH). Loss of homes from fire is not just a problem of dry regions such as California or Florida. Annual spring and fall fire seasons can contribute to fire losses in Ohio.","asOf":"2026-08-25T00:00:00.000Z","object":{"kind":"guide","id":"the-list-ohio-forgot-it-had","title":"The list Ohio forgot it had","url":"/guides/the-list-ohio-forgot-it-had/"},"source":{"title":"Firewise Landscaping: Minimizing the Loss of Structures Caused by Forest and Grass Fires (Bulletin 921)","url":"http://web.archive.org/web/20070714035936/http://www.firewise.org/usa/files/ohio_plantlist.pdf","publisher":"Ohio State University Extension","sourceType":"official","accessedOn":"2026-08-25T00:00:00.000Z","documentDate":"2006-03-01T00:00:00.000Z"}}],"local":[]},"placeFocusedGuides":[{"id":"the-list-ohio-forgot-it-had","title":"The list Ohio forgot it had","url":"/guides/the-list-ohio-forgot-it-had/"}],"findings":[],"plants":{"grain":"state","total":918,"nativeDocumented":21,"invasiveOrNoxiousFlagged":204,"fireResistant":507,"keepAway":140,"conflicts":46,"page":"/grow/ohio/"},"fireEvidencePublicationScope":{"answerGrain":"typed-state-source","sourceCount":1}}
