Garlic leaves turn yellow because of a variety of reasons. These reasons include insects and diseases. The tips of the leaf are often the first to go yellow. The bulb itself may also be yellow. If you are a garlic grower, then you are probably wondering how to keep your plant from turning yellow. Fortunately, there are several different methods that you can try to avoid the problem.
One of the most important things to do is to determine what is causing your garlic leaves to turn yellow. This is the first step in avoiding this problem. You can begin by determining whether or not there are any diseases that are present. You should also check the roots to see if there is any damage. If there is damage to the root system, the bulbs could be susceptible to yellowing.
Another reason for yellowing of garlic is a lack of nutrients. The plant needs a healthy, balanced and neutral soil to grow. Aside from that, garlic plants require nitrogen and potassium to thrive. A good way to boost the nitrogen content is to use ordinary humus. Likewise, you can sprinkle some ashes on the soil to get the potassium back. Aside from that, you can add lime to the soil.
Another reason for yellowing of the leaves is a fungal disease. This disease is common in humid, hot weather. The symptoms of fusarium include watery bottoms of the bulbs, rotting roots, brown and yellow streaks on the feathers, and even a pink coating on the axils of the feathers.
If you have a lot of white rot on your garlic, you can apply a solution of sodium chloride to help prevent it from spreading. You can also use a manganese solution to protect your plants from the disease. In addition, you can also use a solution of potassium permanganate to treat the problem.
The next time your garlic plants start to turn yellow, don’t fret. The most common reason for this is a lack of nutrients. If you have a nutrient deficiency, you can supplement your crops with potassium sulfate or urea. In addition, you can water your plant with a diluted growth stimulant solution.
Another reason for yellowing is a lack of magnesium. When a plant is magnesium deficient, the leaves and the bulbs will also be affected. You can also water the plant with a solution of ash. Aside from that, you can also add calcium to the soil to improve its structure.
Finally, a fungal disease can also cause yellowing of the garlic plant. You can also get rid of this disease by restoring the acidity of the soil. If you are not sure what the solution is, you can consult a pesticide or gardener for a professional’s opinion.
If you are planning to harvest your garlic in the spring, you should do your best to avoid the yellowing of the leaves. You can do this by taking the time to check the health of your garlic and its roots. You can also use some basic organic fertilizers for prevention.
