weekly fruit and vegetable crop update 5-13-2013

Posted by Kyle Cecil -

1.10 am 4 inch soil temperature: 61 degrees F

2.Growing Degree Days(GDD) Since April 1: 2013 = 199.5 GDD Average** = 170.0 GDD

3.Tomato plant spacing; How close? The answer to this often asked question is that it depends. It depends on the plant type (indeterminate or determinate), the trellising system and how the plant will be pruned? See: http://www.extension.org/pages/18647/training-systems-and-pruning-in-organic-tomato-production for more details. Feel free to e-mail me as well.

4.High tunnel critical temperatures. While raising the minimum temperature is important, keeping the maximum temperature from exceeding a range optimum for crop growth is equally important. See http://anr.ext.wvu.edu/high_tunnel_temperature_management for the range in critical temps for common vegetable crops.

5.Did your fields get a little "too" green this spring? The wet weather keep many of us from doing any prep work for our vegetable crops. If you had significant winter annual weed growth, be scouting for the presence of cutworms. As general feeders, most cutworms attack a wide range of plants. Some common vegetable hosts include asparagus, bean, cabbage and other crucifers, carrot, celery, corn, lettuce, pea, pepper, potato, and tomato. As the winter annual "host" crops are destroyed or die, the cutworms will look for the next most obvious green plants....your crops.
