Plant them 18 to 24 inches apart in a sunny, well-drained spot. Pepper plants need at least 6-8 hours of sunlight per day. Mix compost or other organic matter into the soil when planting. Water immediately after planting, then regularly throughout the season.
Space pepper plants 18 inches apart, in rows 30 to 36 inches apart. Grow plants closer together if temperatures are below 60°F. Closer spacing requires fertilizer at planting and during the summer.
Peppers can be planted in single rows or twin (double) rows on a raised bed. Space the pepper plants 12 to 24 inches apart and space rows about 4 feet apart. If you decide to use a double row, make the rows about 18 inches apart on the bed and put the plants in the ground in a zigzag pattern.
Pepper plants tend to do best when grown in close proximity to each other, but not quite touching.
Everything You Need to Know About Pepper Plant Spacing
At their mature size, the leaves of the pepper plant should be just touching the leaves of its neighbor plants on either side. Anything closer and they're too crowded, anything farther apart means you could have fit more plants in that space.
The Dangers Of Planting Too Close Together
If you plant flowers too close together, the plants get stressed and are prone to diseases, Kole says. If air can't properly circulate and the plants can't dry out between waterings, fungus sets in. Roots can rot. And once plants are weakened from stress, insects move in.
If you cannot achieve the recommended minimum isolation distances of 150 feet and 600 feet for sweet and hot peppers, there are other alternatives for keeping the varieties pure: Grow only one variety, and be sure to check the distance to peppers in neighboring gardens.
Best Companion Plants for Peppers. Tomatoes: Peppers and tomatoes are both members of the nightshade family, and they complement each other well.
Diseases common to both tomato and pepper include Verticillium wilt and bacterial spot. You can limit the likelihood of diseases emerging and spreading simply by following some good gardening practices. Don't overcrowd plants. It makes it easier for diseases to spread.
It's also a good idea to clip away any leaves around the soil line since these leaves are more likely to develop diseases. Once your plants are about 2 feet tall, you can clip away any leaves that are within 6 inches of the soil line. This will reduce diseases caused by soil-borne pathogens splashing up on your plants.
Before planting, fill the holes with water and let it soak in. Into each planting hole, put two or three wooden matchsticks (for sulfur) and 1 teaspoon of low-nitrogen, high-phosphorus fertilizer (too much nitrogen will reduce fruit set).
On 30” beds, 2 rows of Peppers can be planted diagonally, at 18” apart; expect yields of 10-20# per plant over the harvest season. This translates to about 3 peppers per week. On 4' beds, 2 rows of Peppers can be planted parallel, at 18” apart; expect yields of 10-20# per plant over the harvest season.
Space them 10 to 12 inches apart, with the rootball just below the surface or bury up to 1/3 of the stem. Planting closely helps them support and shade each other. For large-podded peppers, planting two seedlings in the same hole helps protect the pods from sunburn because there will be more leaves.
Plant them 18 to 24 inches apart in a sunny, well-drained spot. Pepper plants need at least 6-8 hours of sunlight per day. Mix compost or other organic matter into the soil when planting. Water immediately after planting, then regularly throughout the season.
For pepper plants, a balanced fertilizer with equal proportions of Nitrogen (N), Phosphorus (P), and Potassium (K) is recommended. However, pepper plants respond positively to higher nitrogen concentrations during the flowering stage.
Each plant needs it's own space. Even short, wide peppers like habanero thrive better when they don't get tangled up with their neighbor. Fungal infections, pepper weevils, and hornworms, quickly move from plant to plant infecting an entire crop.
When plants are about 12 inches tall, cut or pinch the stem of smaller pepper varieties like jalapeno, shishito, and Thai back to the second or third set of leaves. This is called topping or tip pruning. The plants respond by sending out branches along the stem, resulting in a fuller, stronger plant.
If peppers are planted too close, they'll grow into their neighbors. This reduces air circulation around the plants and the foliage won't dry off as quickly after watering or rain. Wet foliage is an invitation to disease.
Peppers and chili go well next to cucumbers, especially in a greenhouse you can plant these crops together. To prevent mildew, garlic, onions, chives, marigolds and various herbs such as basil can help.
Space in-ground holes 18 inches apart for most peppers; some of the larger bells may need 24 inches. Step 2: Gently remove the plant from its pot. Step 3: Set the plant in the hole so that the top of the root-ball is level with the ground surface. Do not plant deeply like tomatoes, or the plants may rot.
In the case of pepper plants, as self pollinators, they can be pollinated in much the same way as tomatoes although it is rarely necessary. Some gentle flicking of the flowers should be all that is required. You may also use a soft paintbrush to transfer pollen to the stigma.
So, most tomatoes only need an isolation distance of 10-20ft to prevent cross pollination between varieties. Even in a small garden it is quite possible to grow three or four different varieties without any additional steps to save pure seed.
Isolation distance is the minimum separation required between two or more varieties of the same species. for the purpose of keeping seed pure.
