We’ve just summarized the results of our 2016-17 overwintering scallion experiment. In brief, we evaluated several different varieties’ ability to survive overwinter, protected by a single layer of heavy (1.25 oz/yd2) row cover. In this study, none of the many white scallion varieties we looked at had better winter survival than Evergreen Hardy White. However, … More Overwinter scallions: results in
While most of the research farm is blanketed with snow, the growing season is getting started inside our unheated high tunnels. Yesterday, I poked around to check on the status of our experiments. While it was hard to see much inside the low tunnels, which are sealed up tight with snow and ice, the winter sprouting broccoli in … More Checking in with winter crops
Our overwintered onions have sized up nicely, and the tops have fallen for several of the plots. Fallen tops are an indicator of bulb maturity, so once this happens, we start measuring size and weight of bulbs. What are we seeing? There was a fair amount of bolting this year, especially in the earliest planting, which … More Onions down!
We had a chance to peek under the low tunnels late last week, and found some beautiful onions. They’re looking strong and healthy, which is not a surprise given the mild winter we’ve had. Based on prior results, I would not expect that we’d be harvesting them until mid-May, but who knows? Stay tuned.
The tops of many of our overwintered onions have fallen, signaling that they are mature and have reached their final bulb size. We’re pulling these and measuring them, and will then let them dry down. This experiment has approximately 20 varieties planted at five different planting dates in both high tunnel and low tunnels, so there’s … More Onion harvest underway
