Companions: Basil, alliums, beets, lettuce
Peppers prefer a scanty, even water supply, good drainage, full sun, and a long, hot summer.
Tip: Soak pepper seed in water overnight to speed up germination.
NOTE: Number of days is from transplanting

They need a long growing season with at least six hours of full sun. Be sure to wait for the soil to warm in the spring after all chance of frost has passed in your region prior to setting your transplants, and to get a jump start on harvest, set out six- to eight-week-old transplants.
An inch (2.5 cm.) of water per week.
Plants with too much nitrogen become lush, green and large at the expense of fruit. Peppers need more phosphorus and potassium to set fruit. They don’t need a lot of food, 1 teaspoon of 5-10-10 at planting time and an additional teaspoon just at bloom time. Peppers need more phosphorus and potassium to set fruit.

The European corn borer is one bug that can be especially harmful to pepper plants. Plant your peppers near buckwheat to attract beneficial insects that eat the borers. Basil is a good neighbor because it repels fruit flies and some varieties of beetles that feed on peppers. Alliums are great companion plants for hot peppers because they deter aphids and beetles. Plants in the allium genus include: Onions, Leeks, Garlic, Chives, Scallions, Shallots.
Hot peppers thrive in the sun, but their roots actually prefer shaded, moist soil. Because of this, good companion plants for hot peppers are those that provide a lot of shade relatively low to the ground.
Dense, low growing herbs like marjoram and oregano will help keep the soil around your hot peppers moist. Other hot pepper plants are also a good choice. Planting hot peppers close together shields the soil from quick evaporation and protects the fruits, which actually grow better out of direct full sun.

Herbs pepper plant companions: Basil wards off thrips, flies and mosquitoes. Parsley blossoms attract beneficial predatory wasps that feed on aphids. Marjoram, rosemary and oregano seem to have a benign effect on peppers. Dill is said to both attract beneficial insects and repel pests, and companion planting with peppers is also a great space saver. Chives also make great companion plants for peppers.
Vegetables: Tomatoes and bell peppers can be planted in the same garden, but be sure to rotate them to a different area the successive growing season so they don’t pass on overwintering pathogens.
The tomatoes deter soil nematodes and beetles. Carrots, cucumbers, radishes, squash, and members of the Allium family all do well when grown in close proximity to peppers.

Spinach, lettuce and chard are suitable pepper companions. They help crowd out weeds and due to their short stature and rapid maturation, are a great way to maximize garden space and get in an additional crop.
Beets and parsnips can also fill in space, retard weeds around the peppers and keep the soil cool and moist. Beans and peas fix nitrogen into the soil, a necessary nutrient for peppers, and also help block wind and sun.
French marigolds also repel beetles, nematodes, aphids, potato bugs and squash bugs on not only peppers but many other crops.
Plants to Avoid: Brassica family and fennel.

Plentiful peppers
'Plants that spread rapidly, such as mint, can be contained by planting them in a long hollow pipe, buried vertically. The roots then have to go a long way down before they can spread out'
Peppers and chillies demand lots of sulphur to grow healthily — so, when planting them, place two or three unused matches a few inches below the roots.
As the plant grows, the roots will extend down towards the matches and feed off the sulphur, producing a bountiful crop.
