Marigolds and lupines are not just decoration. Their roots secrete toxins that kill the roots of dandelions and couch grass. Plant these flowers around the perimeter of the beds - the weeds will disappear in a month.
Warning: lupines are quite aggressive plants, so do not plant them next to cabbage or beets - they suppress the vegetables.
The best neighbors for these flowers are potatoes and carrots; lupines will definitely not bother them.

As for marigolds, they can be combined with calendula. Together they repel nematodes and aphids.
And if you add tansy to the flowerbed, the ants will disappear forever. As a result, you will forget not only about the ants, but also about the aphids.
Nasturtium will also become an unexpected ally for the summer resident - this flower is capable of suppressing the growth of persistent bindweed.
Its vines cover the soil with a carpet, and its roots secrete alkaloids. Plant it along the fence and you will forget about weeding.
Smart plant growers also have a secret for flower beds.
Sow phacelia between perennials. It not only suppresses weeds, but also attracts bees.
After flowering, mow it down - the mown phacelia greenery will become an excellent natural fertilizer that will appeal to the inhabitants of the flower bed.
No more hours with a hoe! Scientists confirm: such symbiosis reduces the growth of weeds by 90%.
The secret is out - now your garden will be the most well-groomed in the area.
