Blossom end rot is a perennial problem for gardeners. We’ll show you both preventative and immediate techniques to minimize this all-too-common disease.
Fermented chile paste is one of my favorite toppings or condiments: I use it on eggs, sandwiches, in soups, stews and of course stir-frys. Most of the chile pastes found in Asian markets will be fermented to some degree, with those made in America less so. Fermenting your own puts you in the driver’s seat, as you get to choose what flavors go into the process and how hot or mild the result is. After you’ve made a batch or two, you’ll reach for your ‘special sauce’ before anything else!
We’ve just made a different type of fermented chile paste and wanted to share the process with you. This is completely different than our other chile fermentation recipe – Fermented Pepper Sauce. This method is still a lacto-fermentation, but instead of depending on the natural lactobacillus bacteria on the chiles, it uses organic whole milk yogurt to jump-start the fermentation process. What we’ve found is that this method really adds to the complexity and roundness of the flavors while decreasing the heat considerably. This is so delicious that a small dollop goes well on top of real vanilla ice cream!
This is a very quick recipe – our fermented chile paste was finished in just about 4 – 5 days, instead of a couple of weeks to a month for the more traditional lacto-fermentation. We hardly saw any bubbling in the air pockets, with none on top. Because of the yogurt culture providing the fermentation engine, we didn’t need to cover the chile mixture with water and then strain it out later.
The chiles we used were heirloom Anaheim and Serrano chiles, with only about 10% being Serranos. I used the Anaheims for the mildness and well-rounded flavors, with the Serranos, providing a different flavor dimension and some good heat. I just cut the stems off of the Anaheims, but seeded, de-veined and de-stemmed the Serranos and the initial mixture was still pretty shockingly hot! The heat was an immediate, front-of-the-tongue heat which is typical for Serranos. The initial odor was unmistakably sharp fresh chiles and garlic, but after one day it smoothed out and had a very pleasant odor. After two days it started to smell very mellow with sauerkraut overtones and the chile/garlic combination fading. When it was finished the two odors were pretty well balanced, with the flavor being remarkably smooth, rich and long lasting. The heat had really mellowed, to a very moderate background that never intruded or was uncomfortable, only adding to the experience.

Here’s what could come out of your garden for this recipe – Chiles and Lemongrass!
When the flavors are to your liking, it is done. If left alone, the fermentation will continue for a month or more, so don't feel you have to wait on it.
Make sure that you have at least one full inch of headspace between the top of the chile paste and the lid, otherwise it can bubble over and make a mess.
Ripe Chiles for Fermented Chile Paste
We started with fully ripe heirloom Anaheim and Serrano chiles – the Anaheims for flavor with the Serranos providing a nice heat.
Removing Seeds and Veins from Chiles
The next step was to remove the ‘heat’ from the Serrano chiles by removing the veins and seeds. These contain the capsaicin which is a yellow oil in the seeds and along the veins.
Deseeding Chiles
A butter knife worked well to slip into the chile and remove seeds and veins all at once. Note the disposable gloves to protect my hands now and eyes later!
Chile Paste Ready for Fermenting
After the chiles and garlic were chopped up in the food processor, the yogurt and salt were added, then pulsed to mix in well. Be careful when pushing the chile mixture down to keep your face away from the opening, as it can be quite pungent, depending on your chile selection!
Transferring Chile Paste to Jar
After the yogurt and salt are added, the chile mixture is transferred to the fermenting jar. We started with the quart jar, but it was too full so we transferred to a half gallon to give it enough space.
Fermented Chile Paste
After about 5 days, the fermented chile paste was ready to go. It started to mellow in the aroma after the 2nd day, and by the 4th it had a sauerkraut odor with undertones of chile – surprisingly delicious! We transferred the paste back into a quart jar to store in the refrigerator.

The final product glamour shot!
Blossom end rot affects mainly tomatoes and peppers, but can affect other fruiting crops such as eggplant, watermelon and summer squash. This is a perennial problem, meaning that as a gardener, you will deal with this yearly in your garden. There are two approaches to working with blossom end rot – prevention and reaction, or a primary and secondary solution. Unfortunately, most gardeners only realize they have a problem when the fruit are showing black spots on the end. This is the acute phase – once there are problems – and immediate action is needed to prevent further damage to fruit that is just beginning to set.
We will look at the underlying causes of blossom end rot, along with what happens and what can be done about it in the prevention as well as the acute phase.
As mentioned, blossom end rot will affect more than just tomatoes and peppers, but we will focus mainly on those as this is what most gardeners’ experience. Just tuck the other varieties into the back of your mind, and you’ll have a jump start if you see it strike them. In reality, the prevention will most likely have a beneficial effect for everything as you will be creating an environment that won’t support the cause of the problem!
Blossom end rot is caused by a lack of enough available calcium in the fruit at the blossom end. What most often alerts us is a black spot or patch at the blossom end of the tomato or chile, opposite of the stem. This black spot is a secondary issue caused by a fungus attacking the weakened fruit. Contrary to what many think, we aren’t aiming for the eradication of the fungus and resulting black patch, but fixing and preventing the cause of the problem. Correcting the underlying issues that lead to the weakened fruit will automatically prevent the fungus from being able to attack.
Let’s start with the problem and work backwards, to better understand what is needed for both an acute fix and a preventative approach for blossom end rot. Calcium is a very important part of the growth process for plants and the proper development of high quality, tasty fruit as it contributes to healthy cell wall growth, insect resistance and helps to regulate many cell processes. Calcium is non-mobile in the plant once it is imported, meaning the plant can’t move it from one part of itself into the fruit, or from one part of the fruit to another. Thus, the tomato or chile plant needs a continuous supply of calcium as it grows, flowers and produce fruit all through the season.
Blossom end rot usually occurs early in the season with the first or second flush of fruit. It happens just when the plant is at maximum growth and is putting on the first fruit, with a second set of flowers on the way. It is in high gear and needs all of its nutrients available to be healthy, resist pests and disease, as well as grow lots of delicious tomatoes and peppers. The key to preventing blossom end rot is to supply a sufficient, steady amount of calcium to the plant so it can be transported into the fruit continuously. Problem solved!
Not so fast, just how can we make sure that the plant has a steady supply of calcium?
Early Blossom End Rot
Here is where we branch off into the two approaches – the primary and the secondary. The primary, preventative approach is to have enough calcium in the soil that feeds the roots and is transported to the fruit throughout the growing season. That calcium in the soil must be ‘available’ meaning that the roots can actually absorb it and transport it where it is needed. Available means that it isn’t tied up by another mineral or a pH level that won’t ‘let go’ of it. There is more to the story than just adding a calcium amendment to the garden bed!
A very good example of this is where we live in central AZ, there is a decent amount of calcium in the soil that plates out on faucets and glassware as a calcium deposit. Conventional wisdom says not to worry about calcium because it is everywhere. That’s true, but the challenge we have is the pH of the soil is fairly alkaline at 8+ on the pH scale, so the calcium is ‘tied up’, or not available to the plants. This is proven by the weed populations we typically see that only grow in calcium deficient soils.
So what can be done? A comprehensive soil test is one of the best, first steps to take. This is much more than the simple NPK type of test done by university extension offices or the do-it-yourself test kits bought at the local garden center. A complete soil analysis is one that is collected and sent off to a recognized, professional lab that sends back a report on every mineral found along with recommendations on what direction to go and what nutrients to add in what form. They will usually cost from $25 to $75 range, depending on what analysis and information you need. There are several of these labs in the US; the two that we’ve worked with and are familiar with are Crop Services International and Texas Plant and Soil Lab. From this, you will have a very good indication of where to go next.
Fall is a great time to get your soil tested and amended in preparation for next spring’s season for a few reasons – the soil testing labs are generally not as busy, so results are quicker; and soil amendments will need some time to become integrated and available into the soil nutrients, so fall gives you the needed time, and it is easily incorporated into the traditional fall garden cleanup and prep.
Calcium is closely tied with magnesium, and this will be indicated on the soil analysis. More acidic soils, such as those generally found in the eastern states, will benefit from lime or calcium carbonate, while the more alkaline soils in the western states will need gypsum or calcium sulfate. Lime tends to raise the pH, while gypsum tends to lower it.
Water plays an often overlooked, but equally important, role in the blossom end rot saga. Inconsistent levels and rates of water will greatly vary the amount of calcium and other nutrients available to the plant, increasing the chance of diseases attacking the fruit like blossom end rot. This is one of the reasons we talk a lot about a drip system on a timer – it really helps even out the moisture levels in the soil and greatly reduces the stress on the entire garden, with the happy result of lowered amounts of nutrient and stress related problems. Of course, the weather can also play havoc with all of our carefully laid plans, as heavy and sudden rainfall can cause blossom end rot and splitting of tomatoes, along with a noticeable ‘wash-out’ of flavor and taste.
This is where the acute or secondary approach is needed. Calcium carbonate tablets, or anti-acid tablets (Tums or the equivalent) work great when a couple of them are inserted at the base of a tomato or chile plant, where they will dissolve and make the calcium available to the plant in just a few hours, saving this flush of fruit if done right after the rains, or the next set if done when blossom end rot is first noticed.
Another approach is to feed calcium directly to the roots through the drip system as a liquid fertilizer, usually with calcium chloride or calcium nitrate. This approach works very well in offsetting one of the most overlooked causes of blossom end rot – great weather. That’s right – excellent weather with moderate temperatures and lots of sunshine put the plants into overdrive, and their rapid growth can often simply outstrip the amount of available calcium in the soil, even if you have been proactive last fall. The calcium just cannot be taken up out of the soil fast enough, so feeding through the drip system can be a big bonus during these times. The secondary approach will always be needed, even if you’ve done your homework and amended the soil the previous fall.
Calcium isn’t absorbed very well by the leaves of a plant, especially older leaves. The roots are much better at absorption, plus they can transport the calcium faster than through a foliar approach. For these reasons, stay away from trying a foliar spray to supply calcium to your tomatoes.
Blossom end rot won’t ever quite go away, because of the reasons you’ve seen here. With some knowledge and practice, you can easily create a much better environment in the soil that supports the plants much more fully and then use the supplemental approach to keeping the calcium levels high enough to minimize blossom end rot and keep more of your hard work for your dining table instead of as scraps for the chickens or compost pile!
