One of the most common questions we get this time of year is “Should I keep fertilizing my perennial beds with Miracle Gro?” There is a rather long scientific answer that has a lot to do with cell division and nutrient uptake and storage, but the short answer is, “No.” August is when plants begin the process of preparing for winter. Part of that process involves a slowdown in growth. When we apply standard fertilizers, we are telling them we want them to keep growing. The two messages don’t work well together.
What we recommend instead are products that provide a slow release of nitrogen, while at the same time providing the phosphorus and potassium your plants need. Our favorite product for this is Coop Poop, an aerobically composted chicken manure. Please visit their website to learn more.
