A: I’ve had a hard time controlling weeds in my bermuda lawn this year. Is it possible the above-normal rain has had an effect?
Q: It’s very possible that the extra rain has benefitted weeds. The definition of a weed is “a plant that out-competes the plant you want”. If you have not fertilized regularly, the bermudagrass may be unable to dominate the crabgrass as it should. It’s also possible that rainfall has diminished the action of the pre-emergent you applied months ago. It might be a good idea to apply crabgrass preventer once again and make sure your lawn is well-fed.
