| Yellow is probably OK. For an uneven color, or anything tending to brownish, it might be safer to snip off the tip. Better safe than sory here, and you can squeeze the sheath along the long dimension near the top and cause it to open up a bit. Sometimes you can do the squeezing with out cutting, and cause the sheath to open at the top, or even get hold of the sheath on both sides and pull the sheath halves apart at the top. Be sure to use a sterilized tool, as cutting these before they are good and brown means you are cutting into living tissue, and you don't want to transfer virus to the plant. Cynthia |
