Do your houseplants always seem to turn dull and lifeless after a few seasons spent indoors? The Miracle-Gro Indoor Plant Food spikes are perfect for those without a green thumb—and those who simply can’t remember to feed their greens. Place one of the spikes in the soil of any flowering or foliage houseplant to feed it for two months in the winter and fall, or one month in the spring and summer. The spikes consist of micronutrients that keep plants lush, happy, and healthy. Available at Home Depot; $2.28 for a pack of 8 spikes.
