jc,
Sorry to hear that, but hope you will get to harvest some nice ones before they are all gone.
The dry/hot mid summer here made it hard on our seng to. We probably saw 500-600 plants on Mondays dig, but only 3-4 yellow ones. We have had some decent rain the past month or so that I think helped ours hang in there, but the hot/dry june/early july seems to have made our seng produce fewer berries and I have seen a bunch of seng that had no berries at all.
I don't think they just fell off and are gone, I just don't think they set fruit.
I have a little patch just off the back yard - some small 2 prong roots I transplanted last fall. Some of them are small 3 prongs this year and they had flower spikes, bloomed, but never set on berries.
