Generally speaking if you are planting, the best time is the end of April. The Old Farmers' Almanac gives a date for CT of 4/25. Below is a chart from their website with growing information. Here's the link: http://www.almanac.com/content/frost-chart-united-states
What I normally do in spring is apply manure as a top dressing to my hop plants. Other people I know use chemical fertilizers made for garden vegetables. I will give more info when I get closer to that time.
