ROCHESTER, Minn. - The focus of Friday's midday theme at RochesterFest was Earthfest.

It gave people a chance to learn about the different ways they can help take care of the planet and add some beauty.

Kids and adults were able to get their hands dirty and do some guerilla gardening by making a "seed bomb". You can make your own seed bombs at home too by getting clay, rolling it into a small ball, forming it into a tiny pot, adding some dirty and a seed, rolling it back into a ball and then throwing it into a vacant area to grow and bloom. 

"This has been done for a couple hundred years and some will say that the Japanese take credit for it. This is how they used to plant their fields because of the nature of the fields and the clay would keep the seeds protected and it's also weighted enough so that it will stay in place enough for when the rains come," explained Rochester Earthfest's co-chair, Mary Idso.

This years Earthfest theme focused on water. The theme next year will take a look at green building and living in energy efficient homes, as well as operating energy efficient businesses.
