Sweet Pea Advice From Montana!
Today recceived a short letter from Sister in Montana with a newspaper clipping called "Dirty Fingernails" by 2 mastergardeners in that area. It includes exstensive advice & info. for growing sweetpeas! Not much that I hadn't read before, but an explanation of the "why's".
"s.p.'s are one of the kinds of seeds with an extremely hard coating to it, it's hard for the water to get into the seed and start the germination process. You can sand the seed with an emory board, nick it with clippers or soaking it, so that water can penetrate that coating, just being careful not to damage that coating where the sprout will appear". Now that I know why I'm suppose to do it, I'll try again. However, this season I did start the seed in a flat indoors and they did sprout! So far, so good! I'm assuming that this "reason" applies to any tough seed coating.
