Now that the temps are getting into the 90's you will see Bermuda kick in. I've been cutting and bagging it about 1.75-2". Reason is most clients are on a twice a month schedule. My first app of fert I used 24-2-11 with 6% iron @ 1lb N per 1000sf2. They are green and looking good. Once the temps kick it in I'll adjust my navigator to mulch mode by closing the chute. I'm not able to maintain them much shorter due to frequency of visits.
For those that missed the timing of pre-m I went with 3 way ester II @ 1oz per 1,000. Seems to have kicked back weed pressure. Now I'll back off the 3 way and go with Celsius or momentum
