Gardeners who enjoy container gardening out of necessity or proclivity often have success growing pepper plants in pots. Select a container large enough to accommodate the root system of a pepper plant and place the container in a sunny growing area. With adequate water and fertilization, a pepper plant of any variety will grow to substantial size, providing a generous pepper harvest during the last half of the summer.
Fill the planting container with potting soil almost to the top and add 2 to 3 tbsps. of time-release fertilizer into the potting soil. Mix the fertilizer well to incorporate it into the soil.
Remove the pepper plant from its temporary container by loosening the soil and then gently pulling it out. Place the pepper plant into the planting container immediately, then carefully fill in additional potting soil around the roots.
Water the pepper plant immediately after planting and place the container in full sunlight. Keep the soil evenly moist by watering to saturate the soil.
Fertilize the pepper plants by mixing the water-soluble fertilizer with water when the pepper plants develop the first peppers. Consult the fertilizer package for mixing recommendations, then use slightly less fertilizer to make a somewhat weaker fertilizer solution. Pour the fertilizer carefully around the soil, taking care not to splash fertilizer onto the plants or the peppers as you fertilize. Fertilize the pepper plants two times per month during the remainder of the growing season.
Harvest peppers by picking them when they are a mature size. Cut the peppers from the plants with pruning shears or a sharp knife, clipping them off where the stem connects to the peppers. Continue to harvest peppers as they mature throughout the rest of the growing season.
