Understanding Plant Diseases: How To Keep Your Plants Hale & Hearty

Understanding Plant Diseases: Plants get sick too. Even though it seems dangerous to touch an infected plant, keep in mind that humans are still different from plants. The pathogen, the bacteria that causes everyone to get sick, do not transfer from plants to humans.

Plant Diseases

Now, let’s talk about the diseases that ruin your plants. Here are some of the most common diseases that ruin our plants.


Although not a disease in itself, blight causes a series of symptoms causing the plants to get sick and eventually wither their leaves. Coming from different types of fungi, they usually manifest as forms of molds and bacteria.

Symptoms of blight include browning, yellowing, spotting, withering, and even death of a fruit.

Gardening Tips and Prevention: To avoid blight, be sure to use organic fertilizers and mixers. Ensure that your plants have adequate light and space. Watering your plants with the perfect amount of water will also help prevent blight.

If you think your plants are infected by blight, remove all affected parts immediately. Disinfecting your shears may also help defer its spread. Treat your plants with fungicide and antibiotics.


Plants growing in wet soil are the ones most often affected by root rot. They cause the spread of diseases by infecting the roots, therefore preventing any moisture to be absorbed by the plant itself.

You may be able to identify root rots when you see that the fruits of your plants are dry and wilting. Also, close observation of the roots themselves will reveal browning and drying, instead of white and firm ones.

Gardening Tips and Prevention: Keep the soil dry as possible. Prevent over-watering your plants if possible. Provide adequate and effective drainage/ irrigation system for your plants. If you are someone who uses chemicals for your plants, be completely sure that you know what type of fungi is affecting your plants.


Wilt refers to the loss of rigidness to the non-wood parts of a plant. This simply means that your plant is not getting enough of the adequate water that it needs. Caused by fungi and bacteria blockage, they may cause nutrient deficiency to your plants; making them as dry as possible that will eventually lead to their death.

The symptoms of wilt resemble that of blight. It will start at the browning of the stems until the leaves turn yellow, and soon, the fruit of your plant will not absorb nourishment anymore causing it to dry up and die.

Gardening Tips and Prevention: Like that of rots, remove the affected part immediately. Sterilize your pruning shears with one part bleach to four parts water before use. Remove the weeds surrounding your plants immediately. You can remove weeds, dead leaves, broken bricks by using wheelbarrow or dump carts.

But of course, prevention is still better than cure. So before you plant your seed, make sure that the seed itself is not infected. Ensure that the mixers and fertilizers to be used are organic and slow-release. If possible, do a test run first with one seed.

Article Summary

Plants get infected from diseases but those diseases are not transferable to humans. The most common diseases that ruin your plants are a blight, rots, and wilt. To avoid these diseases, you must use organic fertilizers, water your plant with a sufficient amount of water, do not overwatering your plants, and make sure that the seed you used is free from diseases.
