  1. 4 inch soil temp 58.3?
  2. Growing Degree Days (GDD) Since April 1: 2012 = 188.0 GDD
  3. As hive populations build up, some bee colonies increase their numbers very quickly and some individual hives may become overcrowded. These overcrowded conditions can stimulate a phenomenon called "swarming". Honey bees, that are in a swarm, are not aggressive because they have no hive to defend at this time. These bees, however, should only be handled by an experienced beekeeper. Swarms may stay on a swarming site for as little as 15 minutes or for several days or more. It depends on the length of time it takes for the scouts to find a new hive. So when you see a swarm, keep in mind that they will not be on that site permanently.
  4. Freeze damage to strawberries. Take a look at this great YouTube video from Purdue University on assessing freeze damage to strawberries:

  1. High tunnel production. Grower's high tunnels are full of healthy (except for aphids) lettuce and spinach varieties. Specific to lettuce, seeds germinate best when soil temperatures are between 60 and 65 °F. Lettuce seeds can germinate when soil temperatures are near 40 °F, but emergence is slow. Growers indicate that the head lettuce varieties continue to increase in popularity, from consumers as well as producers.
