The following is provided by Dr. Tom Harris, compiled for the Garden Volunteers of South Texas (GVST):

In April:

WEEDS - They can literally take over your lawn this month if they are not controlled. Frequent close mowing mowing, hand-pulling or the use of an herbicide usually provides adequate control. To control weeds in Bermuda grass, use MSMA or DSMA after the temperatures have risen above 80 degrees F. For weed control. in St Augustine, use Greenlight Wipe-Out or Ortho Weed-B-Gone for southern grasses. Do not mow before or for five days after you apply the treatment. To control nut-grass or nutsedge, use Manage or Image. Follow instructions before applications are made.

TREES - DO NOT prune oak trees now. It's too late. This is prime oak wilt season. If you make any kind of wound from a trimmer or mower on an oak tree, paint it quickly with some type of latex paint. If you hire someone to trim you trees ask to see their license. All Tree Trimmers are to be licensed in Bexar County.
