In this posting, I tell you how to grow wheat in your home garden and provide information about an heirloom variety of that is reputed to be excellent for pasta and bread.
Regular readers of this web site know that I've been experimenting with growing grains in my backyard garden. In the fall of 2009, I successfully overwintered hulless barley and this Fall, I harvested an heirloom variety of flint corn called "Longfellow." (see below photo)
Since I've been on a bit of roll with these grains, I decided to try my hand at growing wheat. I choose a variety called Frassinetto for the experiment. This type of wheat was developed near the town of Frassinetto, Italy in the 1920's and is reputed to be an excellent variety for making pasta or bread. Frassinetto wheat has a protein content of 14%, a very respectable number, even when compared with modern hybrids.
Planting Wheat
When overwintering wheat, plant 8-12 weeks prior to when the ground freezes. This allows the plants time to establish themselves before the Winter sets in but keeps the plants small enough so that they are less likely to be blown down by Winter wind and rain. (I cover this topic in greater detail below)
Commercial farmers use seeders to precisely plant seeds. I planted my wheat by creating rows every 4 inches and dropping seeds about every 4 inches. This was a reasonably precise, but very tedious approach. An alternative approach, is to scatter the appropriate quantity of seeds over the area you intend to plant and then rake the seed into the ground.
I've seen recommended planting rates of anywhere between 2.5 to 10 ounces of seed per 100 square foot plot. I suspect that the large variation in recommended planting rates reflects differences in planting technique (using a seeder versus raking the seed into the ground) as well as different germination rates between various wheat varieties. If you decide you want to try your hand at this, here's what I'd recommend...
- If you can plant fairly precisely, plan on using 4-6 ounces of seed per 100 square feet.
- If you plan to cast the seed and rake it into the ground, plan on using 6-10 ounces per 100 square feet.
Whatever approach you take, the seed should be planted at a depth of about 1 to 1.5 inches.
Maturity
When planted in the spring, wheat matures in 16 to 18 weeks. However, when overwintered, it generally takes between 38 to 42 weeks. Since I planted my wheat on the first day of Fall, I will probably be harvesting in mid June (somewhere between June 16-June 23).
Yields
Reported wheat yields vary dramatically based on type of wheat grown, location, and weather conditions. For example, in a trial done in 2009 and 2010 by the University of California, measured wheat yields for various varieties were between 1,300 and 7,600 pounds per acre. (see table below)
Frassinetto was one of the wheat varieties included in the trial and came in at the very low end of the scale, with a yield of just 1,500 pounds per acre. If I were to achieve the same yield , I would expect to harvest about 3.5 pounds of wheat on my 100 square foot plot. Pretty meager!
However, the test also included some interesting information that may allow me to bump up my harvest if I intervene effectively. If I can prevent lodging, the yield might rise to something closer to 6 pounds.
The Impact of Lodging & What to Do to Prevent It
In the trial, Frassinetto wheat had a 40% lodging rate versus an average of 6% for all the varieties in the trail. "Lodging" is the term used to describe grain plants that have toppled over. This can be caused by either the roots of the plant becoming displaced (generally if the soil is very wet) or by the bending and/or breaking of the stalk itself (caused by wind, rain etc.). Lodging can severely impact grain yield and a shorter varieties of wheat have been developed to help combat the problem. Not surprisingly, Frassinetto was the tallest wheat included in the trial, growing to 55 inches in height versus and average plant height of 38 inches.
To reduce the chance of lodging, I decided to give the wheat additional support. To do this, I placed stakes in the ground every few feet and then connected them with yellow twine. The twine will help keep the wheat stalks standing if they encounter strong winds over the Winter. I ran the string at two heights -- 16 and 32 inches above the ground. There's no magic to those particular numbers; I just placed support at about one-third and two-thirds of total estimated height of the plant.
Next summer I'll let you know if this latest experiment in grain growing worked and whether the extra support helped.
Frassinetto and other wheat varieties can be purchased from Sustainable Seed Company if you are interested.
If you go with other varieties, the University of California data suggests that you could harvest as much as 17 pounds of grain from a 100 square foot plot.
