SOS 400 Super Over Seeding

SOS 400 (Super Over Seeding)

SOS 400 takes the dwarf, dark green, fine leaf bladed characteristics of a perennial ryegrass and combines them with the easy-to-transition characteristic of the annual ryegrasses to produce an overseeding annual grass that is top rated by field and course managers nationwide.

Seeding Rate

  •  Soil Stabilization - 10-15 lbs per 1000 SQ FT
  • Over Seeding Established Turf - 15 lbs per 1000 SQ FT or 650 lbs per Acre


Planting & Soil Preparation

A clean, firm seed bed is recommended prior to planting into bare ground. The seed should be planted no more than 1/4" deep to ensure better germination of the seed. When over seeding ryegrass into an established turfgrass, remember to thin the existing turf canopy to get better seed to soil contact. A few examples of thinning an existing turf canopy would be, to mow and bag the turf lower than what is normally done or verticut the existing turf if possible to open the canopy up. Another option for planting the seed would be to use an overseeding type planter, such as a TriWave (as shown in the pictures below).



Much like perennial ryegrass, annual ryegrass takes relatively small amounts of fertilizer. Starting in February, fertilizer applications can be made monthly through May. Applications are made at 1/2 to 3/4 of a pound of actual nitrogen per month.



Mowing height will vary based on the look that is desired and the type of activities that will occur on the grass. In most cases, the grass will perform and look its best when cut to a height of 1 1/2". If a tighter, more dense turf is desired the grass may be cut to a height as low as 1/2".
