Dramm ColorStorm 9-Pattern Turret Sprinkler Review

Application window: Sod or plug warm-season lawns May through July while they are actively spreading

Application window: The beginning of June to mid-July, which is the exact opposite of the late-August window that works in almost every other state. Kentucky bluegrass goes down at 2½ to 3 lb per 1,000 sq ft, red fescue at 3½ to 4 lb

Application window: The desert ritual: scalp Bermuda and overseed perennial ryegrass late September – mid October for a green winter lawn

Application window: Sprig or sod bermuda May through July; overseed Ozark fescue in September

Application window: Seed fescue in October with the first rains, or in April

Application window: Late April through May, or mid-August through mid-September

Application window: August 15 to mid-September is the window; October 4 is the outside date. Once soil drops below 50°F germination stalls and the seedling that did come up has no root by the first hard frost

Application window: Late August through September for tall fescue, and that window is not negotiable here — spring-seeded cool-season grass in Delaware meets its first summer without a root system. Zoysia goes in as sod or plugs in June, once soil is thoroughly warm

Application window: April–July (warm-season establishment)

Application window: Sod or sprig warm-season lawns May through July; the Blue Ridge counties are the exception, where tall fescue is overseeded in September like a northern state

Application window: Any time of year, given water. Sod, sprigs and plugs are the normal route for the species grown here; the limiting factor is irrigation on the leeward side, not the calendar

Application window: Late August into September is the window. Bluegrass takes 10 to 20 days to germinate, so UI suggests a straw mulch or a small percentage of perennial ryegrass in the mix to hold the seedbed while the bluegrass comes up

Application window: August 15 – September 15 is the prime seeding window statewide

Application window: August 15 to September 15 in central Indiana; reseeding starts from the middle of August

Application window: August 15 to September 15, and that is not a guideline so much as the whole opportunity: seed after it and the crowns will not root before freeze-up

Application window: Tall fescue goes in from late August into September. Warm-season lawns — zoysia, bermuda, buffalograss — go in late May through July as sod, sprigs or seed, once soil is thoroughly warm

Application window: Overseed fescue and bluegrass mid-August to early October — the most productive month of the Kentucky lawn year

Application window: April through July, by sod, plugs or sprigs — St. Augustine cannot be seeded

Application window: Mid-August into early September, matching the same late-summer window as the feeding. Spring seeding means nursing the stand through the summer with a short season to recover in

Application window: Mid-August through mid-October, with late August to mid-September the reliable window before the blackout complicates feeding

Application window: Mid-August to mid-September, and that window is genuinely narrow: seed later and the seedlings do not root before the ground freezes

Application window: Mid-August through mid-September, before the soil cools

Application window: Mid-August into early September; the window is short and closes early this far north

Application window: Sod, sprig or plug warm-season lawns May through July

Application window: Overseed fescue late August to early October; plug or sod zoysia in early summer while it is actively spreading

Application window: Late August into early September is the reliable window; spring seeding works but commits you to carrying the stand through a hot dry summer on irrigation

Application window: Late August into mid-September for bluegrass and tall fescue — the same window as the most important feeding. Buffalograss and zoysia go in late May through June, once soil is warm

Application window: October for tall fescue in the south; sod bermuda in early summer. Northern Nevada follows a conventional September window

Application window: August 15 to September 30 is the window UNH names, and in the North Country the useful part of it is the first half. Spring seeding works between March and May but commits you to nursing the stand through summer

Application window: Late August through late September, before the soil cools

Application window: Warm-season lawns go in from late spring through midsummer once soil is thoroughly warm; cool-season lawns in the north go in late August into September. Establishment irrigation is the whole battle in either case

Application window: Mid-August through late September; Long Island can run into early October

Application window: Core-aerate and overseed tall fescue mid-September to mid-October — the defining NC lawn ritual

Application window: August 15 to September 1 for overseeding lawns thinned by summer — the soil is still warm and germination is fast. Past early September a North Dakota seedling meets winter without a root system

Application window: Mid-August to mid-September is prime seeding; spring is second-best

Application window: Sprig or sod bermuda May through July; seed buffalograss in late spring once soil is warm

Application window: September is ideal and April works — the mild wet autumn is one of the most forgiving seeding windows in the country

Application window: Mid-August through late September; dormant seeding possible in December

Application window: September is URI's month for seeding, and it is short: the coast holds soil warmth into October, but the seedling still needs six weeks of root growth before the ground closes

Application window: May through July, by sod, plugs or sprigs — the warm-season grasses here are not seeded

Application window: The late-season working window is August 15 to October 10 for overseeding, thatch work and repair — seed at the early end of it, because the last three weeks are for everything except germination

Application window: Overseed fescue mid-September to mid-October; sod warm-season lawns in early summer

Application window: May–July for Bermuda; avoid establishment during August heat

Application window: Late August through September is best; spring works but commits the new lawn to its first summer under irrigation

Application window: Mid-August to early September. Vermont does not have New Hampshire's spare fortnight: seed sown in late September in the Kingdom goes into winter without a root system

Application window: Mid-August through mid-October for fescue; warm-season sod and sprigs go down May through July

Application window: April–May or September; new lawns before Memorial Day or after Labor Day, and fall seeding works as late as October 15 west of the Cascades

Application window: Late August into September for tall fescue, seeded at about 3 to 5 pounds per 1,000 sq ft for the fine-leaved types. Zoysia goes in as sod or plugs in June once the soil is thoroughly warm

Application window: Late August into early September is the ideal window for seeding or sodding

Application window: Late August into early September where the season allows it; at elevation the window is narrow enough that spring seeding with irrigation is often the more realistic plan
