There is a lot of months ahead- before its warm enough to seed bermuda , so plenty of time to greatly reduce weeds before planting time. You can't use pre emergent this spring, but you can use post emergent stuff - all the way up to a week before planting. If you had crabgrass this summer, wait until the crabgrass germinates in late spring- spray 'Round up' on it, wait a week, mow the dying grass short with a reel mower, or thatching blade attachment if you have a rotary..... and then seed Bermuda.

Wait until mid June for the soil to be warm enough for bermuda seed to sprout quickly. You can put it down in January, but it will take 6 months to get 80% germination. Much better to wait.
