How to care:
Put fertilizer with small content of nitrogen (delay bloom), add mulch especially in the summer and winter, and in hardiness zone 10b as perennial the plant suffer or die due to the cold of the winter, better to protect the plants and there are varieties that can survive the winter and will bear some fruits in the winter, vegetative reproduction can maintain high quality of cultivar indoor or greenhouse to next season, trellising and support for the plant (sometimes the fruit are heavy and without support the fruits will touch the soil and will be damaged).

Rotten base – When the base of the plant rotten, usually happened in mature plant, better to cover the base with soil until the health part plus 2cm (1 inch) and cover it with soil and even better release the plant from the attachment and make it lay down and reduce 10cm (4 inches) bury and cover it with soil keep it moist and cover with mulch, possible to bury until the green leaves (possible more but no need), in this method the plant will survive more time with new roots.

Problem that the fruits don’t get enough sun – main problem that the fruits grow inside the leaves and because of the weight of the fruits and gravity the fruits will grow down possible to cut the leaves that hide the fruits, but better not to cut the leaves

What is the best way to start growing?
Plant / Seedling / Seed / Vegetative Reproduction – by cutting possible by water or by soil (explanation bellow) or bending a branch over and covering it with soil

Is it necessary to graft or use vegetative reproduction?
No, but it’s possible to use in vegetative reproduction and it’s easy the same as to start by seeds, when start by cutting its ensure the quality of the fruits and from seeds not always can ensure what kind of fruits will be

Possible to start overwinter from seeds use fertilizer with nitrogen (to prevent bloom and increase the growth of the stems) and use the plant to make cutting and in this method can get few plants from one seeds

Keep the stems for next year indoor and take them out in the spring after the last frost by this method possible to grow in hardiness zone 2-10 as perennial by using the cutting over winter.

Difficulties or problems when growing:
Burn above 44 C (111F) in full sun, some Pepper plants are dangerous to eat, Frost sensitive

Planting season:
Spring as annual after the last frost in hardiness zone 2-10a , spring to summer in hardiness zone 10b-11a, spring to autumn in hardiness zone 11b, all year in hardiness zone 12+

How to plant:
Dig a bigger hole than the root ball at least 50-100%, add to the hole organic matter, dead leaves and humus put back some soil and mix it, after this put the plant cover lightly but strong enough that won’t fall put support for the plant and give it place to trellising on it, consider to prune week branches, water it twice in the first day and every day for two weeks, better to plant them few centimeters (inches) under the soil level in order that if there are problem in the base of the plant easy to cover the base and create new root for the plant and not lose all the fruits

Pests and diseases:
Aphids, ants, nematodes, mites, fungus, mealy bugs, powdery mildew, leaf miners, whiteflies, mosaic virus

Pruning season:
All season as annual plant and as perennial better after the fruits if it’s bear fruit all the year

Size of the plant?
30-70 cm, 12-28 inches

Growth speed in optimal condition:
Fast growing / Medium growing, when the plant grow slowly as annual plant better to add fertilizer and organic matter to increase the growth speed

Water requirement:
Average amount of water / Big amount of water, depend the drainage of the soil, temperatures, winds, mulch and watering hours

Light conditions in optimal condition for growing:
Full Sun and in warm climate almost full sun, in desert the fruits and the leaves will burn in the sun reduce the amount / Half Shade – possible but only as perennial and it will bear less and in high summer temperatures

Tip when grow in container:
When grow in container better to fill the container with 10% of soil when the roots fill the soil increase the amount of the soil until the container is full
