Yes Rick, this plant always aborts the last few buds. A couple years tho, enough (35-40) developed to form a complete dome. This last Spring we had a long cool spell here by the lake with temps in the mid-high 60s, then BAM, overnight the temps rose to the high 90s/100 with dew points around 80/84 that lasted a good two weeks. I suppose it supported all it could under the circumstances.
So thats why Terro may not work as well. Well, probably a good thing--I have a private well (pun). I Do!
