Theres web sites to identify Florida aquatic grass i used to have a great one but cant find it, thats very important.
When in Florida you look at small differences within the vegetation, for example take that photo behind you the Kissimee grass field, when you stick a fish lots of times unbeknownst to you there may be a small difference. You have to look and see if its a clump of hydrilla or pepper grass mixed in thats not clearly visible, then you can look and target those areas once you see other clumps. Sometimes it will be a hole like the ones right behind you in the photo. Sometimes the fish will position themselves in a certain area of the grass, try not to to look at the whole two miles of grass and be overwhelmed, look at the details.
Same with any vegetation a 5 mile row of cattails looks daunting but look at the base for other small clumps of vegetation when you stick a fish look it may be by a point.
Points:
Points in other states are large pieces of land or underwater structure the people target and fish, in Florida a point can be a small area were the Cattails or Kissimme grass or even isolated clumps of hydrilla in open water protrude away from the rest. Look down a reed line and youll see small areas coming out into the lake those are points even if it may just be a foot or two farther from the rest.
Isolated grass:
When you see a large row of reeds and notice a few isolated reeds out by themselves even one stick of the reed, hit it. Thats were the big mamma's love to hang. If you see an isolated patch of pepper grass try it.
It all looks the same but it isn't you have yo pay attention to details.
Hope this helps.
