Ghost peppers are so spicy that few bugs pose a problem, but some slugs may bother your plants. If you see chewed on leaves, sprinkle diatomaceous earth (available at a garden store) around the base of your plants.  Occasionally, aphids, pill bugs, or leafminers will bother ghost pepper plants, but this is very rare. If they do appear, ask your local garden supply store for a good quality organic insecticide. If you see spots on your plants' leaves, this is probably a fungus that thrives in damp soil conditions. Back off on watering your plants to discourage the fungus. Ghost peppers will start out green, then become orange, finally a brilliant red. The exact amount of time it takes for peppers to appear on your plants will vary depending on how warm your area is. In most cases, expect it to take 100 to 120 days for ghost peppers to reach full size. The peppers will be 2 inches (5.1 cm) to 3 inches (7.6 cm) long when full grown. The peppers become hotter the longer they stay on the plant. Ghost peppers are extremely spicy and can burn bare skin. Wear gloves, long sleeves, and goggles when you are harvesting the peppers. Clip the stems carefully instead of yanking peppers from the plants. Don't let cut peppers touch your bare skin. Keep children away from the peppers.
Keep an eye out for pests or other problems. Watch for peppers to emerge. Let your peppers mature until they are about finger-sized. Wear protective clothing when handling your peppers.
