Due to the early warm weather, the weeds in our yard have been able to pack an entire growing season into just one month.  Our lawn is covered with (and in some places, consists entirely of) an impressive array of weeds including one variety that produces spring-loaded seeds.  When we brush up against one (when walking by, say), the seeds explode outward in a burst, like an anti-personnel landmine.  We have to be especially careful when bending down to pick something up off of the ground; the seeds can get in our eyes.  These weeds popped up in early March, grew rapidly over the next few weeks, spread their seed (we’ve done a lot of walking in the yard this spring) and are now brown and spent.  Of course, we will be seeing this cycle repeat itself when the next generation sprouts.
