Have you noticed tomato fruit that looks rotten on the bottom? A common problem in the garden, especially when, and a commonly asked about topic, blossom end rot is usually seen in half grown fruits or early on in the season. So what is tomato blossom end rot and what, if anything, can be done about it? Read on to learn more. Blossom end rot (BER) is a physiological condition that results in a brown or yellow water-soaked spot which appears on the end of the fruit where the blossom once was. As the tomato grows, this spot darkens, eventually becoming leathery and black, and may even cover half the fruit s bottom. Often blossom end rot in tomatoes is blamed on a lack of, either by depleted, poorly drained soil or simply from displacement due to transpiration, especially when plants are under stress.
Technically, brown spots on tomatoes from blossom end rot is caused by this lack of calcium. For this reason, you often see it recommended that you should add calcium to the soil or replace the calcium in the plant through a foliar application in order to help correct the problem. But it is actually very rare for soil to be lacking in calcium. Instead, there can be a number of other environmental causes of tomato blossom end rot, from uneven watering due to drought, heavy rainfall or an over caring gardener. Rapid plant growth, especially if given an overabundance of nitrogen early on, as well as fast climbing temperatures can contribute to blossom end rot in tomatoes and other susceptible fruits, like,
Blossom end rot occurs not because the soil lacks calcium but because the plant simply cannot take calcium out of the soil at a fast enough rate to keep up with the growth of the plant or because stress causes the plant to be unable to process the calcium the plant does take up. Unfortunately, this disorder cannot be fully cured, as you can t control nature. That said, tomato blossom end rot can be somewhat alleviated or managed to a certain extent by taking steps to improve or avoid conditions that foster its development at least those more easily controlled by the gardener, like poor soil, watering and fertilizing. and in a well-draining soil amended with organic matter will go a long way in giving the plants exactly what they need to develop healthy growth early on, which means that extra dose of fertilizer isn t necessary.
And if you do, opt for one that is lower in nitrogen and only apply at the recommended rates, or cut by half. Providing adequate and even amounts of is important too. The addition of can help retain moisture while keeping the soil and plant roots insulated. While it may or may not be effective, and is a highly debated topic, the addition of, limestone or calcium carbonate in the soil won t necessarily hurt, but it may not help much either. All in all, the majority of will at some point be affected with blossom end rot. But, in most cases, as the season progresses, this condition will normally clear up on its own without any major ill effects. As for the fruit suffering from tomato blossom end rot, these can simply be picked off and discarded or cut the bad parts out of larger, more ripened ones and eat the rest it won t harm you.
Blossom end rot begins as circular brown or greenish-black patch opposite the stem, often starting out as a dime-sized lesion. With time, the spot turns black and becomes sunken and leathery. Blossom end rot most often affects tomatoes before they are fully developed, often appearing on fruit that is only partially developed. The disorder can affect other plants in the garden, such as eggplants (Solanum melongena), cucumbers (Cucumis sativus), peppers (Capsicum annum) and watermelon (Citrullus lanatus). Some varieties of tomatoes, such as roma, are more susceptible to the condition than others.
