weekly fruit and vegetable crop update 5-19-2014

Posted by Kyle Cecil -

1. 4 inch soil temp: 52.2 degrees F

2. Growing Degree Days (GDD):2014 = 291.0 GDD  Average** = 239.0 GDD

3. Many vegetables and fruits store best at temperatures just above freezing, while others are injured by low temperatures and will store best at 45 to 55 degrees F.  These products can be iced: Artichokes, Asparagus, Beets, Broccoli, Cantaloupes, Carrots, Cauliflower, Endive, Green Onions, Leafy Greens, Radishes, Spinach, Sweet Corn and Watermelon.  These items are damaged by direct contact with ice: Strawberries, Blueberries, Raspberries, Tomatoes, Squash, Green Beans, Cucumbers, Garlic, Okra, Bulb Onions, Romaine Lettuce and Herbs

4. Insects to look for in leafy greens (spinach, lettuce chard etc..): loopers, cutworms and armyworm; aphids, leafminers and flea beetles.  Approaches to control can be found here.

5. When Calcium is deficient and there is no need to increase soil pH, you may use gypsum as a source of Ca. Similarly, you can add Magnesium without affecting pH by using Epsom salts (magnesium sulfate, 10 percent Mg), sul-po-mag (11 percent Mg), or finely ground magnesium oxide (e.g. MAGOX®, 58 percent Mg).
