Tomatoes are a capricious crop that requires constant care. But this does not mean that you will have to spend large sums on fertilizers.
The fact is that some effective fertilizers can be prepared independently from products that are already in the house.
For example, you can make a solution that will protect plantings from diseases.
To do this, in a 10-liter bucket of water you need to dilute just 2 tablespoons of baking soda, a spoonful of sunflower oil and about 30-40 grams of laundry soap.
This simple remedy should be used to treat the bushes to save them from harmful microorganisms.
It is enough to repeat the procedure 2-3 times per season.
Baking soda will help if tomato leaves start to turn yellow too early.
The problem becomes more pressing during hot and dry summers.
But you can deal with this problem by spraying the plantings with a solution made from 10 liters of water and just 1 tablespoon of soda.
