Since these are such great plants to have in the garden I decided to increase my stock of switchgrass by what else? Propagation!
|'Shenandoah' Switchgrass (Panicum virgatum)|
How to Propagate Switchgrass
Now if I want larger clumps I would dig up the whole clump and use a shovel to slice through the entire root system. This method will produce about 4 (sometimes more) decent sized clumps from a large switchgrass. It's more labor intensive than the first method but gives you a larger clump faster. The first method can be done nearly anytime since it isn't very invasive but I wouldn't even consider doing the second method (digging up the clump) unless it was early in the year when we were still receiving rain and the new growth was fairly short. Early spring is probably the best time to divide a large clump.
Have you added switchgrass to your garden?
