Bell Pepper Growing Stages: Watch the colour change!

Bell peppers are not only a delicious snack but also very easy to grow! They come in a variety of colours as well. But have you ever wondered if the different colours of the bell peppers are different plants? I know I did as a child. Now that I am more knowledgeable around the garden, I’m thrilled to take you on a journey through the fascinating world of bell pepper growing stages. From the vibrant green hues to the rich reds, yellows, and oranges, bell peppers undergo a remarkable transformation that not only adds visual appeal to your garden but also hints at their changing flavors and nutritional profiles.

What are Bell Peppers?

Bell peppers, scientifically known as Capsicum annuum, are colorful and versatile fruits that belong to the nightshade family. While commonly treated as vegetables in culinary contexts, botanically, they are fruits. Bell peppers come in various colors, including green, red, yellow, and orange, and each color represents a different stage of ripeness. Here is a quick run down on bell pepper growing stages:

1. The Seedling Stage

The bell pepper journey starts with a humble seed. Select high-quality bell pepper seeds from a reputable supplier or saved from a previous successful crop. Consider the specific variety of bell pepper you want to grow, as different cultivars offer varying flavors, sizes, and colors.


  • Start the germination process indoors using a seed tray, approximately 8-10 weeks before the last expected frost in your region.
  • Plant the seeds in a seed-starting mix, ensuring good drainage.
  • Cover the seeds lightly with soil and maintain consistent moisture.
  • Place the seed trays or pots in a warm location, around 70-80°F (21-27°C).
  • Ensure adequate sunlight or provide artificial light using grow lights to promote healthy seedling growth.

2. The Vegetative Stage

Once the seedlings take root and develop a few sets of true leaves, they are sturdy enough to handle and be transplanted into individual pots with nutrient-rich potting soil. If you plan to transplant the seedlings to your outdoor garden, you need to start the hardening-off process about 7 – 10 days in advance. Gradually expose the seedlings to outdoor conditions, starting with a few hours of sunlight and increasing the time each day.

Choose a sunny location with well-draining soil for transplanting your bell pepper seedlings. Lush green leaves begin to flourish, and the plant focuses on building a robust structure. During this period, it’s crucial to ensure your bell peppers receive the right balance of nutrients, particularly nitrogen, to foster healthy leaf and stem development. Keep the soil consistently moist but not waterlogged. Bell peppers prefer slightly damp conditions. Some bell pepper varieties may benefit from staking or support as they grow and produce fruit.

3. Flowering Time

As your bell pepper plant matures, it transitions into the flowering stage. Bell pepper flowers are usually small white to yellow star-shaped blooms. Bell pepper flowers can self-pollinating, meaning that you can still get fruits even if you just have one plant. However, they dop benefit from pollinators like bees, or a gentle shake of the plants can aid in the transfer of pollen between the flowers, potentially improving the fruit-setting process.

4. Fruit Setting

After successful pollination, the flowers give way to tiny peppers, signaling the onset of the fruit-setting stage. Not all flowers will produce a fruit and it is completely normal! Sometimes, bell pepper plants may experience blossom drop, where flowers fall off before fruit sets. This can be due to stress factors such as extreme temperatures, inadequate pollination, or nutrient imbalances. Ensuring stable growing conditions can help mitigate this issue.

With enough sunlight and nutrients, bell peppers grow quickly once they begin to form. With each passing day, you should be able to notice that the fruits are getting bigger and reach their mature size.

5. Green Bell Peppers: The Early Harvest

The first color of your bell peppers is green. As long as the bell peppers reach their mature size, harvesting at this stage is entirely possible. Green bell peppers boast a crisp texture with a slightly bitter flavor. They are perfect for salads, stir-fries, or as crunchy additions to your favorite dishes. If your plants are producing smaller fruits, you may want to prune away some of the fruits to encourage larger peppers. 

6. Maturation Process: Turning Red, Yellow, or Orange

Here comes the colour transformation! If you’ve ever wondered whether different colored bell peppers come from distinct species, the answer is no. Not everyone is aware of this but all green bell peppers will eventually change to red. The colours merely indicate the level of ripeness. From green, they transition to shades of red, yellow, or orange, depending on the specific cultivar. This change isn’t just about aesthetics; it signifies a shift in taste and nutritional content. Red bell peppers, for instance, are fully ripened and boast a sweeter, fruitier flavor compared to their green counterparts.

7. Harvesting Tips: Timing is Everything

To ensure the best taste and nutritional value, timing is crucial when harvesting bell peppers. Waiting for the peppers to fully mature on the plant enhances their sweetness and flavor, however it also means that they will spend more time on the plant and be exposed to diseases and pests. Be sure to address these issues to avoid losing your bell peppers. To harvest your peppers, gently twist the peppers off the plant, taking care not to damage the stem or surrounding foliage.

Time to feast!
