Timely vegetable crop info for local producers.

weekly Update 4-13-12

Posted by Kyle Cecil -

  1. 10am 4 inch soil temp: 47.1 F
  2. Growing Degree Days (GDD): Since April 1. 83.5 GDD
  3. Twenty-seven degrees Wed. night. Sensitive plants were looking tough next morning. More cold hardy vegetable crops seemed to survive unscathed. Most were transplants with row covers actively used this last week. Colder temperatures (26-31 degrees F) may burn foliage but will likely not kill the chard, lettuce, mustard, onion, radish, and turnip that has been planted.
  4. Soil temp at 4 inch is 47.1 degrees. With these temps, direct seeded crops have a long way to go to get to a 70+ degree germination temp. High tunnels in the area are full of early season lettuce varieties and assorted greens which are growing quite well.
  5. Critical temperatures (degrees F) for cold damage of flower buds based on stage of development. Note with blueberries, there is considerable variability in temperatures at which damage was reported for these growth stages. Strawberry Critical Temperatures - Bud emergence (10); Tight Bud (22); Popcorn (26); Open blossom (30). Blueberry Critical Temperatures - Bud swell (15-20); Tight cluster (18-23); Seperate flowers visible (22-25); Late closed blossom (25-26).
