We have a great compost here called Oakdale, from a poultry farm. It is what Thanksgiving Point uses exclusively; TP is a large non-profit garden, etc. founded by the Ashton family. Ashton was one of the founders of Microsoft. My soil is pretty good (between clay and humus) but it has been years since I have done much fertilizing. I am going to use Alfalfa pellets this year too. In the past I have done fertilizing when I prepared a bed and then sometimes added compost around the iris in the spring.
