As kids go back to school, operations have started the shift from summer crops over to fall crops, which includes the transition from peaches to apples. Peaches are in the ‘Cresthaven’ window, with cultivars like ‘Encore’, ‘Autumnstar’ and ‘Laurol’ yet to finish out the season.  Apples are in...

Now is time to think about those fall cool season crops despite the fact the thermometer feels quite the opposite. I no-till transplanted my fall broccoli & cauliflower August 10. It caught a small shower that day but that didn’t go far and we have watered some to get them established. I also...

Conditions in far southeastern Illinois have been similar to those around the St. Louis area as far as heat and high humidity levels. The sustained, elevated humidity along with temperatures in the mid to upper 90s have created conditions with heat index values ranging from 105 to 110 degrees...

The following article was written by Dr. James Santiago, Assistant Professor Horticulture, University of Illinois Department of Crop Sciences. Many specialty crops we consume develop from flowers including apples, squash, beans, peas, etc. Having an elongated shape, the State of Illinois has...

This summer I observed something that I had not seen before. I am growing delicata squash in my backyard and I saw holes in one. I then observed a couple of other squashes with holes and frass (insect poop) coming out of the holes. I cut open the squashes and found both green and white caterpillars...

Weather update from Trent Ford, Illinois State Climatologist. Most of Illinois hits its climatologically hottest time of the year between the third week of July and the first week of August. This year, though, mother nature didn’t get that message, and the last part of July and much of August so...

Soilless food production systems have become attractive as they present many advantages including more efficient use of the limited resources such as water that can be recirculated, growing food vertically in a small space, fewer pests, diseases, and no weeds that need to be managed, and the fact...

While fertigation is a great way to give our crops an extra boost, we still have many crops grown that are not irrigated and could benefit from a midseason nutrient boost.  I am going to share the equipment I have put together to side dress nitrogen on pumpkins. It could also be adapted to...

WeatherJuly was wet, stormy and hot. End of story. But really, some farms received excessive amounts of rain all at once that left them with temporary flooding conditions that was then combined with days of heat. Between July 10-11, parts of northern Illinois received 3-5 inches of rain. Some...

This season has been hot and dry with scattered rainfall throughout the season for Northeastern Illinois.

Despite oppressive heat and humidity throughout the St Louis Metro East region, peach harvest continues with ongoing reports of good fruit size and quality. Harvest has moved out of the ‘Reliance’ window and into the ‘Red Haven’ window, to include cultivars like ‘PF-15A’, ‘Bounty’, ‘Newhaven’, and...

It never ceases to amaze me just how fast pumpkins grow at this point of the season.  For us moisture has been very good since the first week after transplanting.  These plants have been in the field right at a month.  Pumpkins are starting to vine out and I just put on a side dress...

No-till cover crop observationsPredator insects continue to thrive in the treatment tunnel (cover crops + cut flowers), including the many small spiders. The number of webs within all the tomato and pepper plants is impressive, especially as pest insects can be observed stuck in the webs. The white...

In early June, three cantaloupe varieties were planted under un-irrigated woodchip mulch to measure fruit quality and marketability in Northern Illinois. Varieties selected were ‘Hales Best Jumbo’, ‘Hearts of Gold’, and ‘Honey Rock’, all sourced and donated from Livingston seeds. The field was...

Dr. James Santiago, assistant professor and Illinois Extension horticulture specialist, is seeking grower input with this organic production survey. This 10-item...
