Not started good yet ! When you get several 50° - 55° + nights and longer days you get ready it’s about to get good ! I know that the dog woods are blooming and red buds are blooming etc ! and most say it’s on then but we coming out of a unusual colder winter . drop you a thermometer down in 6-8’ water and check those temps water is still cold. Sure they are some that have prolly came up staring the process but these cooler nights will slow it up. they all want go at the same time but it should be starting to warm up this week!
