There are a variety of garden fruits and vegetables that are particularly susceptible to tomato blossom end rot. Here’s a quick guide to identifying, treating and preventing tomato bottom rot in your garden. 

Tomato blossom end rot is a common garden problem, but not actually a disease from which your plants suffer. This physiological disorder arises from a calcium imbalance within your plants. 

Container plants seem to be particularly susceptible to tomato bottom rot. Luckily, while you won’t be able to cure infected fruit, blossom end rot can be stopped once it starts. 

How to Identify Tomato Bottom Rot

Tomato blossom end rot will begin to show signs only once your fruit begins to ripen. You will notice a leathery brown sphere forming at the base, or bottom-end, of your fruit.

Appearing almost like a dark bruise, the brown area will expand as the fruit continues to rot. 

What Causes Tomato Rot? 

Tomato bottom rot is not caused by the lack of calcium within the soil, but rather your plant’s inability to absorb the calcium. This is many times aggravated by over watering.

Common causes of root rot include: 

  • Soil Fluctuations. Including moisture, nutrient balance and temperature.
  • Excess Nitrogen. Many fertilizers are nitrogen rich and can cause an imbalance. 
  • Root Damage. This can occur when re-planting or when treating soil.
  • Incorrect Soil PH. Your plant may struggle when soil is particularly acidic or alkaline.
  • Cold Soil. Especially during planting, if soil is particularly cold root ends may die off.
  • Salty Soil. If the soil is particularly salty it will affect your plants ability to absorb nutrients.

How Do You Stop Tomato Rot?

Again, once your fruits begin to rot, there is very little for you to do to save them. This, however, doesn’t mean your entire plant will be wasted.

The problem of tomato rot can be treated and most importantly, prevented with proper care.

Eggshells carry a lot of calcium. Keep your eggshells and allow them to dry out. Once dried, place them into a blender and blend until it becomes like a white powder, similar to that of coffee grounds. 

Using your garden trowel or hands  mix the eggshell mixture into your soil. It is recommended to enrich your soil with eggshells at least two weeks before planting.

For some plants it can take anywhere between 6 to 12 months to actually absorb the nutrients from the eggshells. 

2. Adding Epsom Salts To Your Plants 

Epsom salts have long been known to be a beneficial additive for a variety of plants. While you don’t want to over-salt your soil, an occasional Epsom salt watering can do wonders for plant absorption. 

Mix one tablespoon of Epsom salt into about 1 gallon of water. Apply the mixture to your plants every couple of weeks. 

3. Mixing Soil Additives To Your Plants

Amazon offers easy-to-use soil test kits that can tell you exactly what your soil needs more or less of. When it comes to your pH levels, Gypsum and lime are the most common soil additives used. 

There are plenty of soil additives available on Amazon specifically formulated to keep your tomato plants happy and rot-free. 

Adding coffee grounds, tea-bags and banana peels are also great ways to support your soil with some extra nutrients and have been known to support nutrients absorption in tomatoes.
