Answer: A few different things might be keeping the peppers from thriving. First of all, most peppers of my acquaintance, while needing regular moisture, do no enjoy wet feet. The soil should be well drained. Also, peppers are heat lovers, and while I assume your weather has been warm, if you are in a coo microclimate, that may be reason. The Miracle Gro you added to the soil before planting has probably all leached away by now. It is a plant food rather than a soil-building, slow release fertilizer. Youcan use it when plants are actively growing, but it's better all around to build nutrients and humus in the soil. If the horse manure you added was fresh, it may actually be robbing the soil of nutrients while it breaks down. It's better to use aged or composted horse manure to fertilize. Also, it may be the peppers are just experiencing some transplant shock. Give them time, good drainage and warmth and they should bounce back. And always suggest having your soil tested every few years to find out what the nutrient levels are, so you'll know how to fertilize.
