General tips

Some general tips on growing chili peppers gathered from the various sources mentioned in the Sources section:

  • The capsicum plants are perennial (Latin per, “through”, annus, “year”; a plant that lives for more than two years) semi-woody sub-shrubs, although they are usually cultivated as annuals.
  • These shrubs can grow in a variety of soils. Like most plants, they grow better and produce more fruit in rich, soft and deep soils, but they will grow in any reasonably fertile soil and don’t require any special treatment.
  • When fertilizing a capsicum plant keep in mind that, like most fruiting plants, these shrubs like potassium (K). Too much nitrogen (N) will make them grow lots of soft leaves and no fruit.
  • Capsicum plants will produce best when supplied with adequate water. If the soil is well drained, they grow best when watered every day. Plants grown in pots or vases usually need more watering, compared to the same shrubs placed in the ground.
  • For a balanced development, it is best to position the capsicum plant in a place where it is exposed to at least a few hours of direct sunlight.
  • Chili seeds need 20° C to germinate, and it should be 30° C or more for the fruit to ripen. Night temperatures should not drop below 15° C.
  • Capsicum plants are self-pollinating, but insects often cause cross-pollination between plants growing near one another. So, if you want to have chili seeds, you should grow only one variety of a species, or keep the different varieties as far apart as possible.
