Bass love cypress and ceder trees. If you look up the tree the how far out the canopy extends is about how far out the cypress knees grow out from its trunk. Bass and other bait fish hang out in this network of roots. You fish it much like you would any wood cover but always keep in mind how far the roots system extends away from the base of the tree. Sometimes bass will be close to the trunk other times they will hold up on the edge of the roots or somewhere in between. Key lures that do well is bumping spinner baits or crank baits off the knees. Jigs and soft plastics come into play as the water heats up and you need to pick it apart. As you are running lures through the roots pay attention because some knees will be more numerous in some places or some might grow higher than others. It is places like that where the bass might key into and hold on more than others. Motor around and look for a depth change on the edge which will also draw fish. Areas where the trees form a point or lone trees that are set away from the group will be a high percentage area. Sometimes they might grow right on the edge of a channel bank or drop. These trees might seem to replenish with fish so hit it at different times and come back even if they don't produce at the time. Even though these kinds of trees offer tons of cover for a bass where the tree is growing can be just as important and at what depth as to how much a bass is going to relate to them.

Thanks.  I have to be honest with you.  Being from out west the trees here have been a huge question mark to me.

Gotta watch out for hornets in the trees though heard some nasty stories about hitting a tree with the boat or getting to close and hornets just got em
