Fertilizers should be Feared because they create problems for pets, people and even plants.
I love to save, reuse, and recycle but not when it comes to chemicals. I know most of you probably garden organically—like me; however, if you don’t, this is a word of caution for you. Don’t try to save “left-over” chemical contents in a container. One problem is that the label might wear off and you won’t even know what to do with it next year. You’ll be creating potential problems. Storing chemicals can be dangerous because pets and children can get into chemicals and the contents might even leach out of the container.
So, if you are using chemical pesticides and/or fertilizers use extreme caution. There are many ways you can have a beautiful, edible and productive garden without using chemical contaminants.
I always garden organically. I love to use mushroom compost and fish fertilizer to add natural nutrients to my soil. And here are a couple pictures from my garden to show that the garden isn’t suffering. In fact my plants usually outgrow my space.
Here’s how I handle pests and problems I find in the garden:
I tend to use the hand-picking method for ridding my garden of pests. I pick slugs off the plants and put them in my yard-recycling bin. Yes, it’s true, I hate to kill even the peskiest of garden pests.
Plus, I spray soapy water on my rose bushes to wash away aphids. And I pluck off dead blooms to keep mold and mildew from growing in the plant debris. 
And, I try to encourage beneficial “bugs” to come to my garden. I use butterfly bush to attract our little winged friends.
And I plant lots of edibles around the yard. 
I hope this helps give you some inspiration to garden organically.
I like the butterfly bush idea. We could use some beautiful pollinators in our yard!
