Pick a portion of your yard that gets direct sunlight. Then dig holes using the shovel. They need to be 5 inches by 5 inches and 1 foot apart. Use the ruler to measure these distances distance.
Place three or four poblano pepper seeds in each hole. Place plant food on top of each set of seeds. The amount varies by the type of plant food you bought. Follow the directions provided.
Fill in the holes and place a tomato cage on top of each so that the now covered seeds are in the middle of the center of the cage. This cage will keep the plant from toppling as it grows.
Water the seeds daily to keep the soil moist. Touch the soil in order to ensure this. The seeds can take up to a month to germinate. Continue using plant food as directed on the plant food's packaging.
Observe the peppers as they grow. They will be purplish green when young, and when they turn to almost black, they are mature and ready to be picked.
