I live in Austin and the climate is absolutely terrible for a tropical grass like St. Augustine (though all the builders use it for some stupid reason). I would like to go to a more heat/drought tolerant grass that can survive in our brutally hot and dry summers. I've seen many successful Bermuda lawns as well as some with Buffalo. I would like to slowly convert my St. Augustine lawn to Bermuda, but am not quite sure how to do it. I tried spreading Bermuda seed over the St. Augustine and then raking a layer of compost over it, but a bunch of birds came into my yard and ate most of the seed. Will it still germinate eventually or is there some other measure I will have to take? I don't have a ton of money to put into this so I'd like to overseed if possible. I was watering daily after I spread the seed but stopped after I saw all the birds pecking around in the lawn. Any advice would be appreciated.
