Hello just got a bag of dahila tubers One had a long sprout and it broke off. Is it still okay? Thank you Susan
If it has other viable "eyes" then it should be able to grow new sprouts. This thread should help detecting the eyes.
It should be okay. In fact, you may find it replaced with a few sprouts.
Each dahlia eye is actually three eyes if you look really close. If the middle eye sprouts and then is broken off the other two eyes will take over and sprout. If those sprouts are both broken off, they too have three sprouts per eye and will sprout. Each successive sprout gets smaller and smaller, until they are too small to grow. On a large healthy tuber, it should throw up at least 5 or 6 sprouts that will grow a nice plant. Small tubers may only have one sprout that is big enough. Those little bags of tuber clumps have very small tubers. Treat them carefully. Buy full sized tubers from USA sources if you worry about these things.
