I spray garlic with this mixture in the spring after germination. The feathers do not turn yellow, and the cloves grow to the size of a fist

It’s great that you found such an effective way to care for garlic! Spraying after spring germination is really key to maintaining the health of garlic. Here are some tips and information that may be useful:

Composition and effects of the mixture:

Garlic:
Garlic has a natural fungicidal and insect repellent effect.
It helps prevent fungal diseases that can cause yellowing of the leaves.
Strengthens the plant’s immune system.
Cloves:
Cloves also have antimicrobial and fungicidal properties.
Contributes to the disinfection of the soil and the plant.
Cloves can stimulate plant growth, which can result in larger bulbs.
How to spray:

You can make the mixture by soaking garlic and cloves in water.
After soaking, strain the liquid and dilute with water.
Spray preferably early in the morning or late in the evening when the sun is not too strong.
Spray both the garlic leaves and the soil with the mixture.
Repeat the spraying every 1-2 weeks, especially during rainy weather.
Additional tips for caring for garlic:

Soil:
Garlic likes well-drained, nutrient-rich soil.
It is a good idea to incorporate compost or manure into the soil before planting.
Watering:
Garlic requires moderate watering.
Keep the soil moist, but not soggy.
Stop watering 2-3 weeks before harvesting.
Nutrient supplementation:
During the spring growth period, it is worth helping the garlic develop with a nutrient solution.
You can use a nitrogen-containing nutrient solution, for example.
Weeding:
Weeds suck nutrients from garlic, so regular weeding is important.
Important notes:

The effectiveness of homemade sprays depends on the quality of the ingredients and the method of preparation.
If you notice a more serious problem with your garlic, it is worth seeking professional help.
I hope these tips help you have a healthy and abundant garlic crop!
