Last year, with the growth in use of cover crops, seed suppliers seemed to find themselves low on seed when July and August came around. While supplies seem stable now, it would be a good idea to lock in your order soon.
Some apply it themselves, whether the old fashioned way, with a drill. In fact, that’s the surest way to get good soil to seed contact. But more often, growers are opting for aerial applications, whether by plane or with high clearance equipment retrofitted with a seeding boom. Both of these applications predate harvest, so as to get annual ryegrass on the ground with lots of time for optimum growth in the fall. Click here for a page of info on planting.
Here’s a link to a page with most of Oregon’s annual ryegrass seed growers. Many of them also grow other cover crop seed too, whether crimson clover or radish or another. Most, if not all, have staff available for free consulting. Many also have sales and crop consultants living in the Midwest.
One thing to ask the grower, or seed dealer: has this seed been grown successfully in the Midwest as a cover crop? This is a question that will get at two variables…the first – is it winter hardy? And the second – have you had any trouble killing the crop in the spring?
