Zucchini is one of the most unpretentious crops, but to make them grow to the size of a torpedo, you need a little trick.
You can grow a giant even on poor soil if you know what to “treat” the plant with at the time of ovary formation.
And it's not manure, chemicals or magic pills. It's fish waste - heads, tails and entrails, which usually end up in the trash.

Sounds weird? But it works flawlessly.
Fish is a source of phosphorus and nitrogen in the ideal form for plants. These elements stimulate root development and accelerate fruit growth.
Bury the raw waste (1-2 handfuls) in the hole when planting seedlings or next to an adult bush to a depth of 15-20 cm.
In just a week, the zucchini will begin to actively grow ovaries, and in a month you will not recognize your beds. The main thing is not to use salted or smoked fish, otherwise the salt will destroy the roots.
There is a second option for those who are not ready to deal with waste: dissolve pharmaceutical fish oil in water (1 tablespoon per 5 liters) and water the plants at the roots during the flowering phase.
This will give an immediate effect - the leaves will become darker and denser, and the fruits will begin to grow by 5-7 cm per day. But be careful: such watering can be done no more than once every two weeks, otherwise the zucchini will become watery.
Why hasn't this method become popular? Many are afraid of the smell or pests, but if the depth is correct, the fish decomposes without consequences.
If in doubt, add a handful of ash to the hole - it will neutralize the acidity and repel moles.
By the way, you can also feed pumpkins this way, but for them the norm should be increased by one and a half times.
