   Has anyone managed to achieve a successful transition from a Tifdwarf green to Seashore Paspalum (Seadwarf) by sprigging the SP into the Tifdwarf and letting it takeover, all the while keeping the green open for play?
   
   Also, has anyone tried to do something similar on tees or fairways, like from 419 bermuda to SP?
   
   The irrigation water on site is not particularly salty.

   Fairways yes, it is common in Thailand, and by introducing seashore paspalum and keeping the fairways wet it works pretty well:

   I've never seen it done that way on greens.

   I did a no till renovation in Hawaii from 328 to Seashore Supreme. Sprayed out with Glyphosate, scalped and verticut down to sand and then fumigated. Sprigged at heavy rate.
   
   Greens were playable in 90 days start to finish. 60 days minimum from start to finish if needed to push. Just pick the warmest time of year to speed up the growth and plenty of water.
   
   Without Brackish or high salt water the Bermuda will return if not fumigated.

   Look at some of the seeded varieties. May be possible to interested the Paspalum into the Bermuda during aerification.

   Though I have never done a Paspalum grow in on an open course.....Something similar to Andys suggestion is to graden (or sisis) the greens in two directions 1/4"-1/2" deep. Seed with sea-spray paspalum at 1-1.5lbs/1000sqft and then bury your greens in sand. Keep it moist and it will pop in 10-14 days. Keep the sand heavy enough to protect your seed but not too much that players complain.
   
   If members don't care about brown greens then id also apply round up two times before the whole process. Sea spray will cover quite fast at the 1.5lb rate. Ive gotten good coverage out of a .75lb rate on horrible soils with magnesium toxicity so its quite an aggressive grass.
   
   But id definitely try this out on a practice green first.

   Was actually talking with a guy involved with an interseeding process like I mentioned last week at the show. They said winter is better timing as the Bermuda tends to lay down and not do much while the Paspalum is more aggressive in cooler temps. Kind of like the high rate of Primo just without applying the product.

   We had a Tifdwarf practice green in Panama that we converted to Seadwarf. We stripped off the the Tifdwarf after 3 or 4 Roundup applications, added a bit of sand, and laid Seadwarf sod.
   
   Three years later the green was about 90% Tifdwarf again. I am sure that only spraying Roundup wasn't good enough, but I think the quick return to the original Tifdwarf could equally be contributed to the Seadwarf being pretty susceptible to dollar spot. Dollar spot was always an issue during the rainy season on this green and the Tifdwarf appeared to return first in areas most affected by this.
   
   We had similar experiences planting Seadwarf sod on a few renovated tees that were previously a mix of 419 and common bermudagrass.
