Southwest Michigan vegetable regional report – May 29, 2013
Cool temperatures bring little change in vegetable crop development in the southwest region.
According to Michigan State University Extension, temperatures for the week at the Southwest Michigan Research and Extension Center averaged below normal with highs from 51 to 78 degrees Fahrenheit and lows from 34 to 60 F. Low temperatures on May 24 and May 25 caused slight damage to new transplants, but no significant losses have been reported. At the Southwest Michigan Research and Extension Center as of May 28, there has been 429 base 50 growing degree days. The area received 0.50 to 1 inch of rainfall during the period.
Recent rain has not been enough to slow field work and has helped with bed shaping, transplant establishment and seed germination.
Asparagus harvest continues with few problems.
Pepper, tomato and eggplant transplanting continue. Low tunnels will be taken off soon from tomatoes so pruning and staking can begin.
Low tunnels on yellow squash and zucchini transplants will be removed soon so bees can get to the flowers. Direct seeding continues.
Watermelon and cantaloupe transplanting continues.
Early planted sweet corn has changed little since last week and is still 4 to 6 inches tall and a bit yellow due to recent cool, cloudy conditions. Color should improve over this week.
Peas are at early flower.
Early planted potatoes are 6 inches tall. No Colorado potato beetles have been observed.
