Callawassie Island Agronomy: Week 12

Grassing and grow in is now in full swing. With Magnolia 3-7 well into grow in focus has shifted to grooming these holes to the correct mowing heights and pushing lateral growth to fill in the voids in the sprigged areas. With the grass on these holes well established, we can now back off the water a little and dry the soil enough to allow equipment to perform routine maintenance. The Tif-Tif sprigs have really begun to go sideways now that routine mowing and fertilizer applications are being made. Successful sprig grow in's require routine mowing to be successful. Mowing the grass forces the the growth sideways, thus filling in the voids. Without mowing, too much vertical growth occurs which can lead to a thin turf stand. We have made one topdressing application and will be making several more over the coming months to help smooth the surface and fill the voids left behind from the sprigging operation, rain fall, etc. So far the sprigged areas on Magnolia 3-7 are looking great. The sodded tee complexes have also firmed up enough on these holes that weekly mowing is now part of the routine. The Zeon zoysia is really impressive and will provide a great playing surface for golf. The tee tops themselves have been cut down to the playing height we will maintain once open. Sand topdressing and some light aerificaiton of the tee tops will be required to level out the tees and fill in the sod lines. Now with Magnolia 3-7 mostly complete, focus has shifted to Magnolia 1,2,8 and 9. Magnolia 2 fairway has been sprigged and sod laid down the left hand side rough and around the green complex. The tee complex will be completed next week before TDI moves across the road to Magnolia 1,8 and 9. Shaping and drainage work is ongoing on those holes and the should be ready for grassing beginning next week and into the the following week.

Putting Surfaces:

Wednesday was an exciting day at the maintenance facility, as the Team from Modern Turf showing up to sprig the first set of greens. Magnolia 2-7 were ready for grass and following some last minute adjustments to the mix to ensure the putting greens were back to the original design, these greens were sprigged with our new Mini-verde turf. We will sprig Magnolia 1 green this week and Magnolia 8 and 9 greens soon once they have been built. We expect the sprigs on the greens to take 8-10 weeks to grow in and several more weeks after that to "tighten up" to be ready to open.
