Fixing Thin Wall On Peppers: How To Grow Thick-Walled Peppers (2024)

Are you growing peppers this year with limited success? Maybe one of your issues is thin pepper walls. The ability to grow plump, thick-walled peppers takes more than just luck. Why do you have peppers with thin walls? Read on to learn how to grow thick-walled peppers.

Reasons for a Thin Wall on Peppers

There are a number of reasons for having thin walls on peppers.

Improper Harvesting

The most elemental reason when pepper walls are not thick is that immature fruit is being picked. Sometimes it's hard to tell when fruit is ripe, or sometimes patience isn't one of our virtues. Many peppers appear to be full sized, so we pick them only to find a thin wall on the peppers. The smoothness of the pepper is related to its thickness-- wavy, gnarled peppers are more likely to have pepper walls that are not thick. Gardeners in hot regions need to be especially patient with big bells and sweet roasting peppers. Both of these tend to wait until the nights are longer and cooler in late summer before fruiting and plumping up. These folks may want to plant banana peppers or sweet non-bells, which will ripen in time to use those bumper crops oftomatoes and basil. Peppers need time on the plant to absorb nutrients and water and plump up their flesh, so pack your patience.

Water

Another reason for thin pepper walls is water. Firmness of pepper flesh is directly related to lack of water. Peppers like moist, not wet, well-draining soil. Prior to planting, work some organic matter into the soil to enhance water retention. During hot spells, keep the soil moist by using mulch. Inconsistent watering not only engenders thin walls on peppers, but makes the fruit bitter tasting.

Fertilizer

Peppers are heavy feeders. Immature peppers do not start with thick walls, they grow into them as the fruit absorbs water and nutrients. Areliable soil test may be in order. Peppers grow best in soil with a pH of between 6.2 and 7.0, but they can tolerate a slightly more alkaline soil as well. Either too much or too little of a nutrient can cause problems. For example,potash found in the soil can inhibit nitrogen uptake. Then again, a lack or surplus ofzinc may hamper the plant's ability to utilizeiron and magnesium.Calcium andpotassium are the primary nutrients responsible for building thick walls in peppers. Fertilizing can be tricky. Too much fertilizer will make the foliage develop at the expense of pepper production. Work a 5-10-10 fertilizer into the soil just before transplanting. That is usually sufficient, but you can also side dress the plants with a sprinkle of 5-10-10 when the plants begin to bloom.

Variety

Lastly, thin walled bell peppers may be the result of certain cultivars. Some cultivars are prone to thicker walls than their counterparts. Try planting any of the following varietals for large, thick walled, sweet fruit:

  • Keystone Resistant Giant
  • Yolo Wonder
  • Jupiter sweet pepper

Why are my pepper plants so skinny? ›

Watering your pepper plants can be a major focus area for them not growing adequately. Underwatering pepper plants - especially young seedlings or newly transplanted plants - definitely stunts their growth and dries them out completely.

How do I make my pepper plants bushier? ›

Pruning. While not required, pruning pepper plants allows them to develop stronger, bushier growth. When plants are about 12 inches tall, cut or pinch the stem back to the second or third set of leaves. This is called topping or tip pruning.

Can you plant leggy peppers deep? ›

If they're leggy to the point of being spindly I'd plant them deeper just to keep them from snapping. Just don't expect a profusion of roots as a result. You can plant peppers out at a little bit below soil level and bury them a fraction of an inch, but I wouldn't do much more.

Why are the walls of my peppers so thin? ›

Inconsistent watering not only engenders thin walls on peppers, but makes the fruit bitter tasting.

How to grow thick walled peppers? ›

Test the soil for adequate minerals.

Additional potassium and calcium might be needed to spur good fruit development. Potassium and calcium help produce nice thick pepper walls that not only taste better but also resist fruit rot. These nutrients should be added when turning under the remnants of the year's garden.

Should you pinch off the top of pepper plants? ›

Topping pepper plant seedlings encourages them to grow more bushy. By pruning off the top of the seedling when it's young, the plant will focus its energy on growing side branches – rather than getting tall and lanky. The more side branches, the more places to grow flowers and fruit!

What happens if you plant peppers too close together? ›

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. Separation allows for early detection and keeps plants from competing for nutrients.

Do peppers like to be planted deep? ›

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.

What do overwatered pepper plants look like? ›

Overwatering is a common misstep. It's like feeding your plant a three-course meal when all it wanted was a light snack. The leaves turn yellow or brown, and the plant may even drop old and new leaves.

Why are my peppers not growing big? ›

One of the most common causes of smaller peppers is leaving early fruits to form. During the first few weeks of outdoor growth, you should pick off flowers and fruits. This helps the plant direct more energy into growing roots, branches, and foliage. The early growth translates to a larger harvest later in the season.

Do pepper plants like lots of water? ›

Sweet or hot, most of them pretty much love water and do not like to dry up too much! Always feel the soil before watering - it should feel a bit dry or moist but not wet. There are several ways to water your pepper plant - they aren't very picky as long as they get a lot of water. Choose a way that suits you the best.
