Marigolds should not be thrown away after flowering – any experienced gardener knows this.
This is not a plant that can live out its days on a compost heap or in a pit. If you know what you're talking about, you can make a wonderful pest control product from marigolds.
Marigolds repel pests during flowering, but even after they fade, they do not become less useful.
In their composition, marigolds are close to green manure and remain useful even when they stop growing.
The marigold bushes need to be collected and crushed in any convenient way, together with the root, inflorescence and stem.
The prepared greens are evenly distributed over the beds, after which they are dug up or embedded into the soil in another convenient way to a depth of 20 cm.
It is believed that after such treatment of the beds, there will be no need to worry about pest attacks on carrots, cabbage, strawberries and tomatoes.
Marigolds are excellent at repelling various fleas, aphids and other insects.
