This is my typical procedure when growing from seed:
Tray seeding
Begin by filling the cells of your seed tray with a seed-starting mix, which is lightweight and promotes germination. Carefully place one or two Aji Amarillo seeds in each cell, pushing them about a quarter-inch deep into the soil.
Grow medium
I prefer using compressed coco coir pots for germination, as they allow for an easy-to-manage growing medium available at all times.

Transplanting Guidelines
Once seedlings develop two sets of true leaves, they are ready for transplanting into larger pots. This step is crucial for encouraging robust root systems. Here are some best practices for transplanting:
Water thoroughly after transplanting to help settle the soil around the roots.
Select pots that are at least 6 inches in diameter to allow for adequate root growth.
Handle seedlings with care to avoid damaging delicate roots during the transfer.
The Importance of Good Soil
Before starting to grow, it’s essential to assess the condition of the soil in your garden. The best soil is a blend of mineral-rich dirt and organic matter. In my garden, I compost as much as possible to enrich the soil with nutrients. I use both hot composting for food scraps and cold composting for organic garden waste.
If you don’t have the time or space to compost, you can purchase compost from Amazon, local garden centers or use community composting programs. Learn more about community composting here: Learn more about community composting here.
Where I live I get a large tax refund every year for composting may own organic waste. Due to this saving I was able to break even on the cost at only two year use. I recommend you to check with your local government if you can receive any tax refund.
Care
- Water: Keep the soil consistently moist, particularly during growth cycles, avoiding over-saturation.
- Fertilize: Use balanced fertilizers regularly to support strong growth and fruiting.
- Pest Control: Regularly monitor for pests and diseases, employing organic treatments as necessary.
Pollination Strategies
Though Aji Amarillo peppers can self-pollinate, manual assistance can enhance fruit production. Gently shake the plant or brush pollen between flowers to optimize yield.
Harvesting
Aji Amarillo peppers are ready to harvest when they are firm and display a bright yellow-orange color, typically 70-85 days after planting.
