Some people who like to eat very hot chili peppers say that they can help you breathe better if you have a cold. Others believe that chilies give you energy.

Do you want to fire up your meals with homegrown chilies? They need a warm climate. If you plant the seeds outside when the weather is cool, place them under glass, giving them the warmth of the sun and protecting them from the wind. You can also start the seeds in your home or a greenhouse. If you’re planting inside, fill a 7.5-centimeter pot with soil. The pot should have holes in the bottom for water to run out. Tap the sides of the pot to settle the soil.

Drop several seeds onto the surface of the soil, and cover it with a thin layer of vermiculite (蛭石), which can hold air, water and nutrients. Then cover the pot with a see-through plastic bag and place it in a warm area.

When the chilies start growing, take off the bag. When the plants have grown to about two centimeters, place each one carefully in its own 7.5-centimeter pot.

When roots start showing through the holes in the bottom of the pot, transplant each of them into a 12-centimeter pot. When the plants are twenty centimeters high, tie them to a stick placed in the pot to support them.

At thirty centimeters, pinch off the tops of the chili peppers with your fingers to make new branches grow. When the first flowers show, give the plants some potash fertilizer, and if the weather is warm, put them into five-liter pots and place them outside. Make sure they get lots of light and water.
