Couple Of Weeks Ago I Planted My Flowers In My Flower Pots Using Miracle Grow With Continue Fertilizer In It That Suspose To Last For 3 Months My Question Is Can I Start Using Liquid Miracle Grow On The Plants Besides What's In The Potting Soil. I Am Not Sure The Continue Fertilizer That's In The Soil Is All That Good And Will Do Its Job. I Don't Want To Over Fertilize And Burn My Plants. Thank You.
