Why do the leaves of garlic seedlings turn yellow
This article guide: The reasons why the leaves of garlic seedlings turn yellow and the primary solution of supplementing nitrogen fertilizer are related contents in the aspect of green plants. The specific details are as follows:
If the leaves of garlic seedlings turn yellow, applying nitrogen fertilizer can help, especially when the old leaves turn yellow, urea fertilizer can be applied to alleviate the condition. If the new leaves turn yellow, crushed eggshells can be placed in the soil. If the leaves are not only yellow but also withered, applying wood ash can supplement potassium elements, and daily maintenance should also be adjusted:
Watering in time is necessary, as insufficient water can also cause leaves to turn yellow.
Supplement appropriate lighting to avoid the phenomenon of insufficient light.
If the soil is compacted, it can be loosened appropriately.
I. What fertilizer to apply when leaves turn yellow
After the leaves of garlic seedlings turn yellow, it is recommended to apply nitrogen fertilizer promptly. If the old leaves turn yellow during the growth of garlic seedlings, it is generally due to a lack of nitrogen fertilizer. Applying urea in time can effectively alleviate the yellowing of old leaves. If the new leaves turn yellow, it is due to a lack of calcium elements. Some crushed eggshells can be placed on the soil surface. If the leaves are withered and yellow, it is likely due to a lack of potassium fertilizer. Applying some wood ash in time can help, as wood ash contains a higher amount of potassium elements, which can alleviate the yellowing of the leaves and restore the garlic seedlings' leaves to a lush green state.
II. What to do when the leaves of garlic seedlings turn yellow
Watering in time: Garlic seedlings prefer to grow in a humid environment. If the leaves of garlic seedlings turn yellow, it may be due to a lack of water. Watering promptly can keep the substrate moist, and when garlic seedlings absorb enough water, the yellowing condition will be alleviated.
Supplement lighting: After garlic seedlings develop yellow leaves, it may also be due to insufficient lighting, which restricts the formation of chlorophyll in the leaves, causing them to turn yellow. Supplementing lighting promptly can restore the green color within a day.
Changing the soil: If the leaves of garlic seedlings turn yellow, it may also be due to unsuitable soil. If the soil is compacted and has poor breathability, the growth of garlic seedlings will be restricted, leading to yellowing leaves. It is recommended to change the soil at an appropriate time to improve soil aeration and looseness, and the yellowed leaves will gradually recover.
The above is the complete content about why the leaves of garlic seedlings turn yellow and the primary solution of supplementing nitrogen fertilizer promptly, have green plant enthusiasts understood it?
