clematis not blooming
We have 2 clematis on one trellis. Unfortunately we don't know the names (though one is a summer bloomer and one is a fall bloomer), but last year they bloomed a little. This year there's lots of green and they've grown beyond the height of the trellis, but one or two flowers and that's it.
I cut them down in the late spring since they were all twisted together. Are there too many together or too large for the trellis's so no blooms? HELP!!
