I have long given up on keeping weeds out of the 'lawn'. This is mostly due to the fact that our lawn is just pasture grass we keep mowed down right around the house.
Even if we had a real lawn there is no way to keep the weed seeds from the fields that surround the property from blowing in and sprouting up in it...so we don't try.
So instead of worrying about dandelions I enjoy them for the photogenic nature. This was taken at dawn on a morning that had quite a bit of dew. The moisture made the seed heads less 'poofy' than usual, making it so you could see right down into the dark ball at the middle.
It is so easy to love a dandelion when you relax about your yard!
So don't freak out about weeds...photograph them!
Although I will admit it makes mowing a bit conflicted!
