The Hawaiian Chili Pepper (Capsicum annuum), native to Hawaii, is a popular and distinctive chili pepper variety known for its fiery heat and unique flavor profile. These compact, bushy plants typically reach heights of 2 to 3 feet and feature small, elongated, and wrinkled fruits that start off green and mature to a bright red or yellow color.

These pepper plants thrive in warm, tropical climates and are well-suited for cultivation in Hawaii’s favorable conditions. They require well-drained soil and plenty of sunlight to flourish.

These peppers are highly valued for their exceptional spiciness, often ranging from 50,000 to 70,000 Scoville Heat Units (SHU), making them significantly hotter than common jalapeno peppers.

Due to their intense heat, Hawaiian pepper is used sparingly in a wide range of culinary dishes, including salsas, hot sauces, and marinades, adding a fiery kick to the cuisine.

Their distinct flavor, which combines a fruity and slightly smoky undertone with searing heat, sets them apart from other chili pepper varieties.

These Chili Peppers are not typically found in mainstream supermarkets but can be obtained from local farmers’ markets or grown at home gardens.

Cultivating these plants can be a rewarding endeavor for chili enthusiasts, allowing them to enjoy the bold flavors and heat of this unique Hawaiian chili pepper variety.

Hawaiian Chili Peppers Farming

The time it takes for chili peppers to mature varies depending on the specific variety. In general, most varieties reach maturity within a range of 70 to 150 days. For sweeter pepper varieties, you can typically expect to harvest them in a shorter time frame of 60 to 90 days.

On the other hand, if you desire a hotter pepper, it will typically require a longer growing period of approximately 100 to 150 days to develop its characteristic spiciness. It’s important to note that these timeframes are approximate and can be influenced by factors like growing conditions and climate.

Cultivating Hawaiian Chili Peppers can be started from seeds, typically Hawaiian Chili seeds germinate in 10-14 days. Alternatively, propagation from cuttings is possible by planting 4-6 inch stems in well-draining soil. Here we are trying to inform you how to grow Hawaiian chili peppers.

Location Selection

To ensure robust growth and maximum flavor in Hawaiian Chili Peppers, it’s crucial to provide them with at least 4-6 hours of abundant, direct sunlight each day.

Ideally, the more sunlight they receive, the more favorable the conditions for achieving larger and spicier yields.

Avoid cultivating these peppers in shaded areas, as inadequate sunlight can result in leggy, stretched-out plants with diminished fruit production.

Optimal sun exposure not only promotes vigorous growth but also enhances the distinct spiciness and flavor profile that Hawaiian Chili Peppers are renowned for, making it essential for successful cultivation.

Soil Preparation 

For successful chili Pepper cultivation, it’s essential to select the right soil blend to promote healthy growth.

The ideal soil mix consists of high-quality potting soil with excellent drainage properties. To enhance drainage further, incorporate 1-2 handfuls of materials like coco coir, perlite, or vermiculite into the mix.

To enrich the soil and provide essential nutrients, consider adding well-rotted manure or compost in combination with peat moss, coco peat, or mulch, along with vermiculite perlite, or even sand for improved aeration.

A valuable addition to this mix is 5-10 grams of neem cake during planting. Neem cake acts as a natural protector, safeguarding young plants from soil-borne diseases and pests, ensuring a robust start to your chili cultivation journey.

This carefully crafted soil blend not only fosters optimal drainage but also provides essential nutrients and protection for your chili pepper plants, setting the stage for a successful and bountiful harvest.

Water Management 

Maintaining consistent soil moisture is essential for the plant, as it has a high water requirement. The growing medium should never be allowed to become completely dry. To gauge moisture levels, gently touch the topsoil; if it feels slightly dry, it’s time to water.

However, be cautious not to wet the foliage during irrigation, as overhead watering can potentially lead to fungal infections.

Ensuring well-drained soil, regular monitoring of soil moisture, and targeted root-level watering contribute to a healthy growing environment for the plant, promoting robust growth without the risk of fungal issues associated with wet foliage.

Temperature And Humidity

The best conditions for seed germination in Hawaiian Chili Peppers occur at temperatures exceeding 68°F (20°C). These robust plants exhibit versatility, withstanding temperatures as high as 95°F (35°C) and as low as 50°F (10°C) without undue stress.

However, the sweet spot for their growth and development falls within the range of 70 to 90°F (21 to 32°C). Within this temperature band, the peppers thrive, manifesting vigorous growth, optimal fruit production, and the characteristic fiery heat that makes them prized in culinary and cultural contexts.


Cultivating Hawaiian Chili Peppers shares similarities with growing tomatoes, but it’s essential to recognize that these plants have robust nutritional demands. To ensure healthy growth and a bountiful harvest, a regular feeding schedule is vital, typically every 2-3 weeks.

However, it’s crucial to avoid nitrogen-rich fertilizers, as they tend to promote excessive foliage growth at the expense of fruit production.

For optimal results, it’s recommended to utilize a balanced liquid fertilizer. Dilute it to half its recommended strength before application, ideally every 2-3 weeks.

Another beneficial practice is the occasional use of Epsom salt, mixed at a rate of 2 teaspoons per gallon of water during watering sessions. Epsom salt provides magnesium, which supports plant health and can enhance yield.

By adhering to these fertilizing guidelines, you can foster robust Hawaiian Chili Pepper plants, ensuring a productive and flavorful crop with the fiery heat characteristic of this unique pepper variety.


When your Hawaiian Chili Pepper plant reaches a height of 6-8 inches, trim the top growth to encourage a bushier appearance. Additionally, it’s advisable to eliminate any early-blooming flowers, as this will help conserve the plant’s energy for stronger growth and a more bountiful pepper harvest.

Pests and Diseases

Beware of typical issues such as rot, mildew, bacterial spots, and potential pests like spider mites and aphids. If faced with a severe infestation, seek advice from a knowledgeable expert to determine the most effective course of action.


Hawaiian Chili Peppers typically require 80-100 days to reach harvest readiness. Once their vibrant red hue emerges, carefully clip them from the plant.

To dry the peppers, lay them out on a clean, soft fabric outdoors, allowing them to bask in the sun and fresh air. Flip the peppers daily to ensure thorough drying.
