Last June when I went to the Desert Botanical Garden one last time before the summer heat set in, I found this patch all covered with plastic and this sign to explain what was going on. It's called "Soloarizing" and it's a natural way to kill weeds. And quite frankly, I had noticed that the wildflower beds were getting a bit weedy.
See what I mean.
When I went back to the garden in September, the ground had been uncovered and sure enough there were no weeds at all.
When I went this last weekend, it had been planted once again and I must say it's looking quite nice. They have placed the different wildflowers in groups that I assume will grow and spread out to cover the area.
I like the way it's looking!
