Bermuda sucks… Speaking from experience. It’s a real PITA to upkeep imho.

1.Minor Problem: You need to get a reel-type mower and not use the traditional blade. Because the grass using a traditional mower, you’ll either end up scalping the grass or not cutting it low enough.

2.Big Problem: Bermuda grass depends on the sun…Lots of sun…
Translation: Bermuda grass looks great in summer..But looks like crap in the winter or periods where there is no sun. If it does not have a lot of sun (like during part of the season), it will turn brown/dry… It will be a problem if your lawn has any shaded areas (shaded from a trees)…
In some climates where I lived, people with bermuda grass ended up having to spray seeds during the winter to keep the green look during winter… In San Diego, maybe it’s not as big of a problem.

3.Sort-of-Inconvenience-Problem: Bermuda grass needs to be aerated properly.

4.Annoying-Problem: Fixing problem areas (spots or dead/dry grass) is a pain. It’s hard to match the grass and patch it up…

5.Big Problem: Getting rid of bermuda grass once it’s planted is difficult…Because of the nature of the root system of this type of grass, it’s really difficult to completely eliminate it once you put it in (even later if you change your mind and want something else). It can be very invasive.
