Weeds are not Wonderful

Garlic cloves are a bit like tulip bulbs; they show up right away and grow rapidly in the spring. They are fast and frost hardy, and nothing stands in their way...except... yes, weeds.
 Garlic is very sensitive to weed pressure. Garlic leaves are narrow and they don't provide enough shade for a ladybug to hide in, which means that they have no real chance of out-competing broad leaf weeds, and really, any type of weed. Garlic has it's ancestry in the central region of Asia, in semi-desert lands, where competition to thrive happens with the sun and weather, not your neighbors. So the texture of a garlic leaf is thick and waxy, with a narrow shape that avoids too much contact with the sun. All traits that enhance moisture conservation. However, garlic grown for the garden or market really does do better with adequate moisture. The difficulty this year is getting moisture and not too much moisture. We've been lucky there, but many of our neighbors have not been so fortunate lately.

  On our clay soil we can't get out and till the ground or hoe weeds when it's wet, and even if we could, you would be surprised at how resilient a 1 inch tall broadleaf weed can be when it doesn't have dry soil and a hot sun beating down on it.  They come back to life!
  A similar thing can be said about large weeds that are just starting to set seed pods. At our place, we've found that it's best to break the weed stalks in a few places, or cut the top off with a hoe, otherwise they use what juice is left in the stalk to complete the task of making viable seed. You see them laying there between the rows, and even though you got them with the hoe the head is turned up to the sun.
  Managing weeds organically has been our focus for the last twenty years, however, and if you have somebody in your team (as we do) who is super ingenious and smart about setting up and maintaining the cultivators, scufflers (row cultivators) tine weeders etc, and managing their timely use, twenty years certainly pays off.

Here I am scuffling the garlic with a John Deere 40 and  the scuffler that  my father  Rob set up.

  We call it managing the "weed bank", which is our term to express the quota of weed seed in any given soil. Someone with a high weed bank will get an instant carpet of weeds after every spring rain. Someone with a low weed bank will see individual weeds as a threat.
  Every weed that is allowed to go to seed adds tremendously to the weed seed account, meaning that to maintain a low weed bank takes constant care. You can actively reduce the weed seed bank by short-period tillage, throughout the spring and summer. Keep this tillage shallow, for annual weeds, and it stimulates the germination of more weeds that can then be gotten. Germinate and expire at least 1000 more weeds than the ones you allow to go to seed, and you've reduced the weed bank for that growing season. It's a way of thinking. And believing in causality is part of it: if the crops are growing - weeds are growing. Count on it. If you cant see them yet, tickle the ground anyway (whether it be with a tractor-drawn unit or a hand held hoe) invariably, if you look close enough, you will see tiny filaments of tender white sprouts in the ruffled-up soil - these are weeds when its easiest to manage them. Just that simple disturbance is all that's needed to stop them. Don't wait if you have the chance to get in your field and do something about weeds, my father usually does a 5 - 10 day interval on his row crops, such as soybeans and corn. Sometimes missing an opportunity these days, means two weeks later it's still too wet to get on the field, and two weeks is a lot of time for weeds to get out of control. The ideal time to weed in any situation, is when the weeds you can see are less than 1/2 inch tall. (1 cm).
Shallow, weed killing tillage can also reduce moisture loss through the dry spells. (Not applicable if you've mulched.) The loose ground on the top 1-2 inches, created by shallow tillage, actually insulates the ground below. Soil that has been rained on thoroughly, but with no sitting water, develops capillary action through the entire top layer, meaning there are pathways for water and air to travel freely in vertical directions. Breaking the very top layer of the soil, cuts off those pathways and keeps the ground from drying out at the surface. This is one reason old organic farmers have the saying "a scuffling is as good as a rain". Another reason they say it, is that soil biology, that is active in the summer, breathes as is metabolizes. Rain water is it's lungs. As water drips into the soil capillaries, it creates movement that draws fresh air in after it. Long periods without rain can deprive the soil life of oxygenated air, making soil life go dormant, and stalling the crop. Tillage can put air into the soil to revive it. Tillage can also be used in waterlogged situations, where water has been sitting too long, and has developed a crust that not air can penetrate. As soon as it's dry enough, go in with deep points (not broad sweeps or wide bladed tools) and get air into the soil. Your crop will thank you.

This picture was taken July 13th, 2017. This is my crop. The plot is 1/2 an acre, 110 different garlic strains (you can only really see Polish Hardneck and Leningrad in this pic). It was scuffled once in the fall, once in the spring, and hand weeded at least  twice. Garlic is hard to scuffle late in season, because the leaves are susceptible to cracking, and unlike some other crops, they do not grow new leaves to compensate for the loss.
One of the reasons I use single, 30 inch rows is because double rows are too hard to weed. With singles I can use machinery to get 80% of the weeds.

To conclude, I wish you all well with your crop, and congratulate you for the hard work I know it to be. What I find special about farming is that every person and every soil has their unique system of what works best for them. Sharing is how we develop perspective, and garner new ideas.
