July 15, 2022Q.Miscanthus X Giganteus Not Growing
Hi, I live in a Zone 5b and planted about four Miscanthus X Giganteus last spring. They did well, but did not come up as of mid July this year. So I dug them up. Soil temps were well above tolerance levels for it to start sending up shoots. So July 14th, I dug them up. I was really surprised to see the roots were alive and growing quite thick and healthy. But NO grass shoots! No rhizomes either, just a woody root ball that were brown with a white interior. These were small 1st year plants but got about 2 1/2 feet last year. My question is WHY are the roots healthy on ALL plants but NO grass shoots with summer waning towards August???

Certified ExpertA.It doesn't sound like the roots are alive. You are right on the verge of hardiness so if your plants were in an unprotected area, they likely froze. Also, if the soil is very clayey or rocky, the plants may have been slow to establish.

August 23, 2022Q.Miscanthus Giganteus Grass Not Growing
Planted two Miscanthus last summer and they did well. This spring they (2) did not come up. Soil warmed up. Still nothing. Late July, I dug them up. Both plants had roots but no Rhizomes. Roots were brown, alive, and had very typical "grass like roots" that were thick. Transplanted elsewhere as I had new ones coming but they NEVER shot up sprouts. It's August 22nd now. Roots appear to be alive still. They were 1 year plants so I don't know if that was a problem. I live in N.B. Canada zone 5B (close to Calais-Maine). Any suggestions? Should I cover the new ones this winter? I didn't cut or cover last years. Soil seems to be fine as they grew well last (old plants), and this, year(new plants).

Certified ExpertA.Your zone will be equivalent to our zone 4b. With this being said, this will be the absolute lowest number climate zone that the grass will survive. Should the winter get just a little colder than usual, you may see some die off.
Mulching in the winter, and removing in the spring will likely help.
