Yes, it will recover. We get this question every year. In fact what you did is an accepted technique for lowering the mowing height of bermuda. You scalped it down below the level you ultimately want to mow. Or, if you really want it at this current height, then wait 3 days for the grass to come back, lower your mower one more notch, and scalp it again. Then raise the mower back up one notch to the mowing height you want. There is absolutely no need to baby it for the next few days. You should be watering about once a week or 10 days this time of year - no additional water needed.

I agree with dchall , Bermuda grass is a rather hardy warm weather grass that thrives in sun light . It thrives with a little water and can tolerate being cut to a 1/2 " with little effect , that is why it is often used for putting greens . Actually here in the Great White North , golf courses is the only area you normally find Bermuda grass ! lol.

It should recover fine. Interesting. The greens at golf course I work at are bent grass.

Actually , yt in the Pacific Rim areas here in the Great White North were grass receives a lot of cool moisture , bent grass is favoured over Bermuda . Both species being a fine blade grass lend themselves to putting greens over Rye species which are utilized in driving box and fairway areas due to their durability traits .

Bermuda grass lawns are not that easy to take care. In some ways Bermuda has good characteristics but in other ways it has some big negatives. Hybrids such as Tif 419 behave differently from non hybrids. Cutting non hybrid Bermuda short all the time is a myth. Can't be done successfully in my opinion. The reason is related to the problem you are experiencing. The green part or canopy doesn't go very deep and it tends to overgrow. Bermuda can grow a half inch a day. The owner is faced with mowing everyday and still the brown ugly underbelly eventually shows through. My method to avoid this is to mow really short in early spring and slowly raise the mower deck over subsequent mowings to avoid the scalped look. Eventually it begins to get catch up anyway and the lawn has some tan or brown areas anyway. Lack of water and or nitrogen makes the problem worse. You can mow the canopy back down to a lower height and start the cycle over if you bag the clippings and are willing to water a lot and put up with a brown lawn for a few weeks. On large yards that alternative is really tough because it's like bailing hay. Golf courses with their enormous budgets can afford exotic low growing Bermuda hybrids and they have perfectly prepared soil, chemical applicators, sprinkler systems, and ridiculous mowing schedules with $75,000 mowers. A residential Bermuda lawn can be kept green and maintained all season if you have access to lots of water. Another problem is keeping weeds out. Bermuda turns a little brown from the application of selective herbicides but it recovers in three weeks. I struggle all season long with invasive weeds and grasses. Overall though a solid Bermuda lawn looks incredible. With its fine blade and dark green color a well kept Bermuda lawn looks like a fine, plush, almost blue-green carpet.
