This winter-spring has been my first excursion into growing strawberries in a high tunnel. It didn’t take much for our own Wenjing Guan to convince me to plant some; who doesn’t love to eat fresh strawberries? We planted them back in October and I just peeked at them every couple of weeks throughout the winter,…Read more about Strawberry Observations from an Entomologist[Read More]
Spring is here and with it comes the emergence of weeds- especially problematic perennials like Canada thistle (Figure 1). Below is some information about Canada thistle and methods to manage it. Keep in mind two things: 1) many of these strategies will work for other perennial weeds, and 2) management of perennial weeds often requires…Read more about Canada thistle[Read More]
The Climate Prediction Center’s outlook for May is dominated by uncertainty regarding both temperature and precipitation (Figure 1). The computer models could not settle on a consistent pattern for either above- or below-normal temperatures for the month and precipitation outlooks are only slightly confident that there will be above-normal precipitation in southern Indiana. Shorter-term outlooks…Read more about Uncertain Climate Outlook for May[Read More]
Two types of injury on young warm-season vegetable plants are caused by low temperatures: frost/freezing injury and chilling injury. Frost/freezing injury occurs when temperatures drop below 32°F. Ice formation in plant tissue cuts cell membranes. When the tissue thaws, the damage results in fluids leaking from the cell, causing water soaked damage. Frost/freezing injury is…Read more about Protect Early Planted Warm-Season Vegetables from Low Temperatures[Read More]
Spring weather is unpredictable. One of the major risks associated with strawberry production is cold damage in the spring. Open strawberry flowers can not tolerate temperatures lower than 30°F, popcorn stage flowers and tight buds may tolerant temperatures low to 26 and 22°F, respectively. If strawberries are in the early blooming stage, the damage might…Read more about Strawberry Cold Protection Made a Difference[Read More]
Staying true to global climate trends these days, March 2020 finished warmer and wetter than the 1981-2010 climate normal period. Snowfall across the state was below normal and localized flooding was a common feature. There were 3-to-5 more days than average in March where rainfall was observed. This has led to saturated soils throughout the…Read more about Was March any Indicator of the Next Few Months?[Read More]
Warm temperatures this week greatly encouraged strawberry growth and development. Some of the early cultivars may have entered the open blossom stage especially if they are grown with the annual plasticulture system in southern Indiana. Open flowers cannot tolerate temperatures lower than 30°F, while popcorn stage flowers (Figure 1) and tight buds may tolerant temperatures…Read more about Strawberry Growers Should be Prepared for Cold Protection[Read More]
