Tomato seedlings are the key to a good harvest in the future. But in order to grow healthy and strong plants, you need to take care of them correctly and on time.
One of the common problems that gardeners face is yellowing and dry leaves of seedlings.
This can be caused by various factors, such as unsuitable soil, lack or excess of moisture, low or high temperatures, lack of light or nutrients, fungal diseases, etc., says Anastasia Kovrizhnykh .
To prevent or eliminate these problems, you need to treat tomato seedlings with a special agent that will help restore their health and immunity.
There are many different preparations for feeding and protecting seedlings that you can buy in stores or make yourself. Here are some examples of such products.
Magnesium sulfate
This is a mineral fertilizer that contains magnesium and sulfur, which are important elements for plant growth and development. Magnesium is involved in photosynthesis and chlorophyll formation, and sulfur promotes the formation of proteins and amino acids.
If there is a lack of magnesium, the leaves of tomato seedlings begin to turn yellow and dry out. To get rid of the yellowing and return the plant to a healthy green color, you should spray the bushes with magnesium sulfate (1 g per 1 l of water) once a week before planting in the ground.
Ferrous sulfate or iron chelate. This is another mineral food that contains iron, an important component for creating chlorophyll and strengthening the plant's defenses.
If there is not enough iron, yellow veins will appear in the middle of the leaves, most likely due to iron deficiency.
To treat tomatoes, you can use copper sulfate (2 g per 10 l of water) or iron chelate (1 g per 10 l of water) once every two weeks before planting in the ground.
Yeast mixture
This is organic food, which contains many useful substances for plants, such as nitrogen, phosphorus, potassium, magnesium, calcium, iron, etc. In addition, yeast activates the growth of beneficial microflora in the soil and increases its productivity.
To prepare the mixture, dissolve 10 g of dry yeast in 10 liters of warm water and add 3 tablespoons of sugar. Let the solution sit for 2-3 hours, and then treat the tomato seedlings once two weeks before planting in the ground.
Iodine mixture
This is a cleansing and stimulating agent that helps tomato seedlings cope with fungal infections and strengthen the immune system. Iodine also helps to form bright and juicy fruits. To prepare the mixture, dissolve 1 ml of iodine in 10 liters of water and treat the seedlings once a week before planting in the ground.
Potassium permanganate solution
This is an antiseptic and disinfectant that protects tomato seedlings from diseases and pests.
Potassium permanganate also improves plant nutrition and promotes their growth. To prepare a solution, dilute 1 g of potassium permanganate in 10 liters of water and spray the seedlings once every two weeks before planting in the ground.
By treating tomato seedlings with these products, you can prevent yellowing and dryness of leaves and grow healthy and strong plants that will delight you with a bountiful harvest.
