If you are new, a novice or experienced Pepper grower this Pepper FAQ list is for you.
1. Q. Why do my pepper plants often bloom but fail to set fruit?
A. Peppers, like tomatoes, are sensitive to temperature. Most peppers will drop their blooms when daytime temperatures get much above 90 degrees F sometimes in combination with night temperatures above 75 degrees F. They will also drop their blooms in the early spring if temperatures remain cool for extended periods.
Hot peppers, such as jalapenos, withstand hot weather fairly well and can often produce fruit through the summer in most areas.
Optimum temperatures fall between 70 degrees and 80 degrees F. for bell-type peppers and between 70 degrees and 85 degrees F. for hot varieties.
2. Q. If I remove the first few blooms on a pepper plant, will my overall production be increased?
A. Maybe. Occasionally, if a bell pepper plant sets the first bloom that flowers, the plant will be stunted as it matures that fruit. This is likely to happen if the plant is growing under marginal conditions which might include low fertility or perhaps low moisture. With the first bloom removed, the plant will grow larger before setting fruit which often does result in higher total yields.
However, if the plant is grown under satisfactory cultural conditions removing the first bloom should not affect subsequent yield.
3. Q. If you plant hot peppers beside sweet peppers, will the sweet pepper plant produce hot fruit?
A. Absolutely not. Pepper flowers are self-pollinated, although occasionally cross-pollinate. The result of this cross pollination will appear only if seed is saved from this year’s crop and planted next year.
It will not result in off flavor or differences in fruit characteristics of this year’s crop.
4. Q. Can I cut back my spring planted pepper plants in late summer or early fall for increased production later?
A. Yes, although this is not a recommended practice. In the northern parts of the United States spring planted pepper plants can often be carried through to first killing frost without pruning.
In southern parts, judiciously pruning the pepper plants and applying additional fertilizer as a side-dress application can prolong pepper production until the first killing frost.
Pruning should not be severe in southern states as excess foliage removal can often result in sunburn, stunting or death of the plants.
5. Q. Is there any difference in taste or nutritive value between green peppers and those that mature and turn red?
A. Peppers that are allowed to mature and ripen entirely, from green to yellow to red, are higher in vitamin content, especially vitamin A. There is little difference in taste although there is a considerable difference in texture caused by the ripening process.
6. Q. How can you tell when jalapeno peppers are mature?
A. Jalapeno peppers are edible and flavorful at all stages of their growth. A connoisseur of jalapeno peppers can distinguish a definite flavor difference between a fully mature jalapeno and one harvested early. A fully mature jalapeno pepper, regardless of size, generally exhibits small cracks around the shoulders of the fruit. Often a darkened area on the fruit indicates maturity and the initial stages of a color change in the fruit.
7. Q. Can I save seed from this year’s pepper crop for planting in my next garden?
A. Yes. Peppers are self-pollinated I recommend saving seed from this year’s garden for planting in next year’s garden.
Although an occasional cross-pollination will occur, this is generally not a problem. Do not save seed from hybrid pepper plants as these will revert to one of it’s parent plants gene pool. This will result in plants exhibiting characteristics different than the desired hybrid.
8. Q. The foliage on my pepper plants developed spots or lesions and the leaves have dropped off.
A. This could be a combination of three foliage diseases: Alternaria leaf spot, Cercospora leaf spot and bacterial leaf spot. In most cases, two or more of these occur simultaneously on the foliage. They can be controlled with foliar sprays using a combination of chlorothalanoil and Kocide or any other copper based fungicide.
Begin treatment at the first sign of the disease and continue at 1 to 2 week intervals until the fungus / disease in cured or under control.
9. Q. The foliage and fruit of my pepper plants are distorted and small. The leaves have a mosaic pattern.
A. This could be one of five viruses that attack peppers. The best control is to buy healthy plants and to follow approved cultural practices and a good insecticide program. The viruses are transmitted by aphids. For this reason, it is important to control insects. Also, when a plant becomes infected with one of the viruses, remove the plant, bag and send to the landfill, Do Not put infected plants in your compost pile.
10. Q. After the recent rainfall, my plants wilted and died. The inner stems of the plants were dark.
A. This is Phytophthora stem rot. It is a soilborne fungus that attacks peppers. It is particularly severe in areas where water stands around the plant. Plant on a raised bed for optimal drainage.
11. Q. After a summer rain, my pepper plants died rapidly. I found a white growth at the base of the plant. Intermingled with this growth were small, round, bead-like structures the size of a pinhead.
A. This is southern blight, caused by a soilborne fungus. Crop rotation and deep burial of organic material will help control it. Do not allow leaves / plant litter to collect around the base of the plant because the fungus will feed on them and later develop on the peppers.
12. Q. There are small wiggly trails all over the leaves of my pepper plants. What are these?
A. These trails are caused by leaf miners. Heavy infestations can defoliate plants and reduce yields. Control this pest by treating with diazinon or a recommended insecticide. Two or three applications at 5-7 day intervals may be necessary to achieve control. Use as directed on the pesticide label.
13. Q. We have just moved to this area and enjoy the Mexican food. What makes Mexican food so hot? Is it the pepper they add?
A. The cooks add pepper alright but not the black stuff you shake from a can – they add green (hot) peppers, Capsicum annum. These peppers contain a chemical named capsaicin. When you eat these “green bullets from hell” there’s a cellular response that releases neurotransmitters. These are proteins that mimic chemically the sensation of burning or pain. They go to the end plate of our sensory nerves and create the sensation of pain. The body’s response is to remove the chemical irritant by increasing heart rate to increase metabolism, by increasing salivation and increasing sweating. Your nose runs and the gastrointestinal tract goes to work in high gear to remove the irritant. You sweat to cool yourself.
14. Q. Can good pickled jalapenos be made from garden grown jalapeno peppers?
A. Yes, if you do not have a good recipe, Search pickling peppers.
15. Q: We have 2 bell pepper plants, in containers, that have until recently been very healthy and produced several beautiful peppers. Within the last week or two the peppers have developed small round tannish spots on the some of the fruit. The fruit were not fully developed, but we harvested then in order to save the fruit, if possible. In cleaning the fruit, the only damage is the small spot or two on the bottom of the peppers. I thought perhaps it was sunscald, but these plants have plenty of leaves. Could they be getting too much sun and would moving them to a shadier location help?
A: Tan or translucent spots on developing pepper fruit is DEFINITELY sunscald. All the young pepper has to be exposed to is a few minutes of direct sun during the hottest part of the day and that does it. Remember the last time you burned your body parts the first sun exposure of the spring?! The same situation! If you can see the pepper on the plant SO CAN THE SUN and it is not protected. A bacterial spot would be black so you can rule that out. You did right by removing the fruit; such removal may stimulate more foliage growth and subsequently more fruit protection.
CLASSIFICATION: There are over 20 species of pepper but only one is commonly known to North American gardeners, Capsicum annuum. This species contains the pepper varieties widely cultivated in North America. Although Hortus lists five groups within the C. annuum species.
SWEET PEPPERS: Bell Pepper, this pepper is mostly blocky in shape with three or four lobes on the bottom of the pepper. For years, gardeners could choose only one color of bell, a green that matured to red, Through modern breeding efforts e can now grow bell peppers that mature to an artist’s palette of colors including red, yellow, orange, lavender, purple and chocolate. The bell peppers have a crisp, thick flesh and are suitable for eating fresh, stir frying or stuffing and baking.
Paprika When dried and ground, this thin walled pepper becomes the flavorful condiment paprika.
Pimiento is a heart shaped pepper measures 3 1/2 by 4 1/2 inches. Fruits have very thick flesh. Strips of this fully mature, bright red, mild tasting pepper are found in stuffed green olives.
Sweet Banana, Sweet Hungarian, Cubanelle all of these are also referred to as sweet frying or pickling peppers. The shape is long, narrow tapering down to one, two or three lobes. These are thinner walled than bells and Cubanelle has the thinnest walls of the three. They are usually picked when immature as a light yellow or green. Because they have less water content than bells, they are excellent choices for frying. ‘Sweet Banana’ is a variety that has withstood the test of time, it was a 1941 All America Selections Winner. ‘Gypsy,’ a 1981 AAS Winner is early to matures in only 62 days and performs very well in containers as well as in regular gardens.
Sweet Cherry is a pepper that looks like its name in that it is globe or cherry shaped and about 1 1/2 inches across. This pepper is harvested when mature green to deep red and is generally processing as pickled.
HOT PEPPERS: Cayenne pepper is slim and tapered, ranging in length from 3 1/2 to 8 inches. Cayennes are often dried. The hybrid ‘Super Cayenee’ is a 1990 All American Selections Winner. It is very productive, early to mature and hot, hot, hot.
Red Chili the small cone-shape peppers of this type are 1 to 3 inches long and have medium thick flesh. They are often used dried and ground in chili powder. ‘Super Chili,’ a 1988 AAS Winner is the first hybrid chili. The compact plants were bred for increased yields.
Green Chili are long (7 to 8 inch) green, two celled mildly pungent Anaheim type peppers that are so flavorful in chile rellenos. They turn red at maturity but are nearly always harvested, green, roasted and peeled. They’re the kind you’ll find in the canned goods section of supermarkets labeled “Green Chile Peppers.”
Hungarian Yellow Wax (also called Hot Banana) this pepper is pungent but still one of the more mild “hots.” It is 5 to 6 inches long and picked when an immature greenish yellow color but matures to orangish red. This type is good for pickling or canning.
Jalapeno are the popular peppers used in many Mexican entrees. They are 2 1/2 to 3 1/2 inches long and have a thick walled pungent flesh. They may be harvested when immature green or mature red and are good for pickling or canning. There are many varieties of jalapeno peppers with varying degrees of pungency. It has been said that more than 200,000 pounds of jalapeno seed is planted in Mexico annually.
Red Cherry a hot pepper is only 1 1/2 inches across and shaped like a cherry. It may be used fresh or pickled, primarily pickled.
Red Hot Pepper types are other Capsicum annuum in the Longum Group that add distinct flavor to their native regional cuisines. These vary in plant and fruit size and shape. Smaller plants are attractive in patio containers and hanging baskets. These scorchers such as Chili Tepine, Chile Peguin, Tabasco, and Thai, mature red and zest-up foods. Small hot yellow peppers like Cascabella and Santa Fe Grande are used primarily for canning and pickling. Is one of the hotter Serrano type that is popular in the Southwest.
Then there is Habanero, said to be 50 times hotter than Jalapeno peppers.
NUTRITION: Peppers are the right food for people seeking a healthy, nutritious diet. Low in calories, high in Vitamins A and C, peppers are also high in a very important mineral, potassium. One cup of raw sweet green peppers contains 22 calories. For comparison a cup of cucumber is 16, cottage cheese is 223 and a whole orange is about 41 calories.
A red sweet or hot pepper contains about ten times more vitamin A and double the amount of Vitamin C than an immature green pepper. A 100 gram serving of red hot peppers eaten raw contains 369 milligrams of Vitamin C. The same serving size of sweet raw green pepper contains 128 milligrams, about one third less.
Whether green or red a pepper contains more Vitamin C than a whole orange which contains only about 50 milligrams. For potassium rich foods, an average banana contains 370 milligrams and a cup of green sweet pepper has 213 mg raw and 149 mg if boiled before being eaten.
