 Hi, we're your Prairie Gardens plant experts. We're often asked how to fertilize containers in outdoor garden beds. Let's talk about containers first. We have time-release fertilizer that you can incorporate into the soil while you're planting. And then you could also supplement with water-soluble fertilizers, usually about every two weeks. And flower beds, I like to approach that differently. I like to incorporate compost into the soil as a very gentle fertilizer. Come to Prairie Gardens, located at Springfield and Duncan in Champaign.
