How Long Does A Hawaiian Chili Pepper Plant Take To Bear Fruit?

Although it always depends on the variety, most of them mature in 70-150 days. For sweeter ones, you can typically harvest in 60-90 days. If you want it hot, it will take 100-150 days. 

Propagating Hawaiian Chili Pepper Plant

Hawaiian Chili Peppers can be quickly started from seed. It usually takes 10-14 days for the seeds to germinate. You can also grow them from cuttings, by snipping off a 4-6 inches long stem and planting it in well-draining soil.

Requirements for Growing Hawaiian Chili Pepper Plant 



For best growth and flavor, make sure Hawaiian Chili Pepper gets a minimum of 4-6 hours of bright and direct sunlight every day. The more it gets, the better it will be for better, bigger, and spicier yields.

Avoid growing it in any shaded space as it will make the plant leggy.


The best soil for Hawaiian Chili Pepper is good quality potting soil with good drainage. Add 1-2 handfuls of coco coir, perlite, or vermiculite to the mix for better drainage. 

You can also add well-rotted manure or compost in the combination of peat moss/coco peat and vermiculite or perlite (alternatively, sand).

Adding 5-10 grams of neem cake at the time of planting will protect the young plant from soil-borne diseases and pests.

It is ideal for keeping the soil evenly moist as the plant needs plenty of water; the growing medium should never dry out completely.

Keep an eye on the topsoil and water the plant when it feels a little dry to the touch. Also, avoid wetting the foliage as overhead watering may cause fungal infection.

Temperature And Humidity

The optimum seed germination happens above 68 F (20 C). It can tolerate temperatures up to 95 F (35 C) and down to 50 F (10 C) easily.

The ideal growing temperature is between 70-90 F (21-32C).

Hawaiian Chili Pepper Plant Care



Growing Hawaiian Chili Pepper is very much like tomatoes so bear the fact in mind that these plants are heavy feeders. You’ll need to feed the plant every 2-3 weeks. Avoid using nitrogen-rich fertilizer as it will result in more foliage.

The best is to use a balanced liquid fertilizer, diluted to 1/2 of its strength, once in 2-3 weeks. You can also use Epsom salt (2tsp/gallon water at the time of watering) to improve the health and yield.


Once the Hawaiian Chili Pepper is 6-8 inches tall, clip the growing tip to promote a bushier plant. Remove any flowers that bloom early, reducing the plant’s overall energy. 

Pests and Diseases

Be careful about common diseases like rotting, mildew, bacterial spots, and pests like spider mites and aphids. Consult an expert to know the best action in case of severe infestation.
