Gardening is an activity that, according to physical and mental health professionals, which requires paying attention to the needs of plants compared to natural resources. Although some plants have different needs than others, it is important to contemplate when they begin to turn yellow and brown; as they are symptoms of certain diseases, such as chlorosis.
Chlorosis can result when there is not enough level of the pigment chlorophyll - which provides the green color - to the extent of causing plant death. There can be numerous reasons why the plant does not get enough chlorophyll in its plants; such as:
- Nutritional deficiency. Beyond hydrogen, carbon and oxygen, plants need a number of other mineral nutrients to survive. A soil rich in minerals can feed the roots, facilitating their expansion towards the branches and leaves. If the plant is nutrient deficient, the veins in the leaves will turn yellow or begin to grow abnormally. This happens because there are not enough nutrients to move through the plants. In this case it is advisable to use organic fertilizers.
- Pests. Unlike nutritional deficiency, the symptoms of a plague tend to develop in asymmetric patterns. This can happen from damage done by insects such as fungi or bacteria on plants. Insect damage can lead to chlorosis, which can be solved by non-toxic methods like plant repellants, neem oil, or DIY organic pesticides. To control fungus in the garden, spraying the plant with baking soda can help regulate pathogenic conditions.
- Water and light. Too much or too little water can cause discoloration of the leaves; therefore it is important to understand the needs of plants in relation to water and light. In other words, too much water can drown and deminiralize plants; while little water can dry out and destabilize the waters.
