Hi there, I recently purchased a couple of grape vines, although it is too cold here (Michigan) to plant them I have put them in a sunny window and they are growing like crazy. Yesterday I noticed there were tiny clear jelly like things on the stems...I shook the plant over a piece of paper to see if anything crawled but didn't see anything. I do not know if they are eggs of some sort or if this is normal for a grape vine. I have never grown grapes before and would love any advise I can get.
