Here are two videos about garlic and inter-planting garlic with salad greens.
I plant garlic here in southern Wisconsin in late October. I plant the cloves along the top of ridges of a raised bed that has been shaped into three ridges (or two troughs). After I plant the garlic I mulch it deeply with straw.
I plant the garlic on the tops of ridges in my dense clay soil because garlic likes to be well drained. I’m minimizing the chance of the garlic getting water-logged then frozen as it goes through our often very cold winters under its insulating straw blanket.
In spring, I pull back the straw and inter-plant salad greens of all types along the edges of the ridges and in the troughs. The greens are somewhat protected from the sun by the garlic flags. The inter-planting gets me two crops out of the bed at the same time.
The first video shows how I use both CobraHead tools to help me remove the matted down straw. The second video explains the inter-planting process.
