Like tomatoes, their nightshade relative, sweet peppers have a natural affinity for basil. Both share similar demands as to climate, soil type and pH, sunlight and water. Although neither deters garden insects or diseases from the other, house gardeners find them easy to care for at precisely the exact same moment. Within an aesthetic sense they’re great companions because the green or dark purple leaves of basil form a backdrop for the colorful peppers.
Requirements in Common
Both sweet peppers (Capsicum annuum) and basil (Ocimum basilicum) thrive in warm weather. Neither should be planted until all threat of frost has passed, and the day temperature is growing to 65 degrees Fahrenheit. Since both require full sun, take care to plant them where neither plant will probably be in the other’s shadow. The perfect soil pH for basil is 6.4 and 6.5 for sweet peppers, so both prefer slight acidity. Rich, well-drained soil is another requirement. Water basil liberally every single season. Sweet peppers have exactly the same water demands until the fruits approach adulthood, once you should curtail watering to boost flavor.
Improvements for Both
If your lawn soil tests too alkaline for basil and sweet peppers, the optimal solution is to dig in a lot of acidic organic matter, such as bark, peat moss, leaves or sawdust. This should make the soil more fertile and looser for better drainage, as well. To warm the soil before planting the two heat-lovers, lay sheets of black plastic over the ground for several weeks. Since both plants are susceptible to the exact same soil-borne disorders, rotate crops each year. Avoid planting where cucumbers, peppers or any of their relatives, like tomatoes, potatoes or eggplant, have already grown. Basil should grow in exactly the exact same bed just once every 4 decades.
Pests and Diseases
Not just do basil and peppers not protect one another from insects and diseases, they share some of the very same antagonists. But if they’re in close proximity, treatments are readily implemented to plants. Cutworms, whiteflies and nematodes may attack basil, as well as sweet peppers. When peppers are seedlings, cutworm grubs can cut down the plants close to the ground surface. Placing 3-inch cardboard collars around the honey and pepper seedlings, in the time of planting, offers cutworm protection. Spraying with strong jets of water may handle the whiteflies. Both plants are prone to fusarium and verticillium wilts. Though no cures exist for the diseases, plant resistant breeds of honey, such as “Magical Michael” or “Nufar” and “Bell Boy” or even “Early Pimento” peppers.
Other Beneficial Companions
Basil and sweet peppers each feed heavily on nitrogen, but gardening specialists warn against adding more because peppers might put more energy to foliage as opposed to fruit production, and basil’s taste could be compromised. Growing beans or other beans nearby can result in more efficient usage of this nitrogen already there. Marigolds interplanted with the vegetable and herb might repel the nematodes and other pests that threaten them.
