Weeding The Lupines Again

It is that time of year again.
The Natal grass was starting to build up in the second lupine planting area.
Last year I wasn't aware there was a problem and didn't get to it until later in the season and it took several visits to complete.
 Today I got the bulk of it cleared out in about four hours.
The weeding revealed how few surviving plants there are.
I also saw one Scrub Blazing Star in the patch. I can't remember whether there any last year.
