Humans and animals are not the only ones that get sick in the world. Plants do so, too, being living creatures as well. Unfortunately for plants, they do not have the means to verbally communicate their pain and distress when they suffer from any kind of disease.

If you truly value your role as their owner and carer, then you should know that proper and consistent maintenance is critical to their health. You should also do your best to continuously learn about the newest plant diseases that have been discovered together with the latest and most effective treatments and prevention techniques that you can use to protect your plants.

Regular Cleaning

Gardens also produce and are subjected to waste, and these can be dangerous to your plants’ health if they are allowed to remain in the area far longer than what is safe. Waste can lead to the presence of virus or bacteria, which could then infect your plants with all sorts of diseases.

To keep your garden clean and free from any kind of plant disease, it is best if you could invest in high-quality mulch. Make sure you apply it to the top layer of your soil as well regularly and whenever necessary.

Remember to remove all dead parts of your plants, flowers, or trees. These could become infected or are already infected, and the disease can spread to harm the healthy plants in your garden.

Air Circulation

Plants need a well-ventilated area just like humans and

animals do. Excellent air circulation allows plants to “breathe” more easily, because the atmosphere is not as humid and uncomfortably moist as it could be.

To improve air circulation, you need to give your flowers and plants as well as trees and shrubs room to breathe. True enough, some species do not mind being crowded with other plants, but there are also species that require a huge amount of space to grow.

Air circulation is also hampered by irregular and insufficient trimming. So if you have perennials in your garden, be sure to trim or prune them regularly to prevent excess parts from being exposed to infection or disease.

Air circulation is also dependent on finding the right method and location to grow plants. Pumpkins or squashes are best planted in rows. Tomatoes, peppers, and other bushy plants are more suitably grown, on the other hand, in wire cages as this will prevent their stringy and extensive branches from touching the soil, which could be infected by all sorts of viruses and bacteria.

What to Do if Plant Diseases Do Show Up in Your Garden

Here are several steps to take if it turns out that a disease or illness of any kind has indeed invaded your garden.

Step 1: Do not panic.

Step 2: Examine all plants thoroughly in your garden. Look for plants that are damaged or may be infected.

Step 3: Cut out all infected parts of plants. If necessary, remove the entire plant to prevent further and quicker spread of the disease.

Step 4: Place it inside a garbage bag and seal tightly.

Step 5: Dispose of the infected parts in an environmentally safe method.

The Most Common Kinds of Plant Diseases

Here are a few types of plant diseases that can find its way to your garden if you are not careful.

Blight - Caused by fungal infection, this disease is especially harmful to plants or crops like potatoes and tomatoes. The presence of blight can be easily identified by the leaf spots they create in infected plants. In plants like tomatoes, blight can also result into stem lesions and fruit rot.

Black Spot - Rose gardeners from all over the world consider black spot disease as the bane of their existence. Those growing hybrid tea roses should be especially worried as such species are weaker against this disease.

Damping Off - This type of plant disease targets plants that are in their seeding or seedling phase. If you notice that certain seeds in your garden are taking an exceptionally long time to germinate, take a good look at their colouring. If they had only turned brown without showing signs of growth, that is a possible sign of damping off damaging your plants. If it is also softer than it should be when touched, then that is another indicator as well.

All types of plants can be attacked by disease so that a knowledge of the early signs of infection and of the way in which a disease can be combated is valuable.

New varieties of plants are being produced all the time by various methods of selection and inbreeding. Highly bred plants are, however, not necessarily highly resistant to disease.

Where one particular type of plant is grown in quantity, often on the same ground year after year, an outbreak of disease can cause serious losses. This trouble is more likely to arise in glasshouses and probably in flower beds that are replanted each year with the same or similar types of plants. Treatment of the soil in early spring or late autumn when the site is vacant will often be necessary.

The term "plant disease" refers to anything - except insect damage - which may check the growth of a plant, cause abnormal growth or death. Included, therefore, are parasitic organisms, unsuitable soil, incorrect temperature, injury from fumes and sprays or excessive liming. Fruits and vegetables  - such as apples, pears, potatoes and carrots-continue to live even when stored and can suffer from various troubles which either reduce their food value or destroy them entirely.

Plant diseases may be divided into two main groups: non-parasitic diseases, which are not infectious and parasitic diseases, which are infectious. The latter may be subdivided into two classes: fungous and bacterial diseases; virus diseases.
