We're seeding wheat between rows of cash crops. This prevents erosion and stops weeds from germinating. Here are the rows seeded, then germinated.
Erica said the tallest they'd get would be three feet. But they'll probably stay shorter as we will be stomping on them as we harvest. Wheat is also very easy to mow. We also have a few daikon radish seeds spread between the rows because they grow pretty huge then die and leave a nice little empty hole in the soil when the decompose. It's like tilling minus the tractor!
The white stuff is row cover, which we're using for pest control. It can also be used to keep plants warm.
Our kale is doing very well! I picked a bunch today and had it for dinner.
