About this module
This is a curated view into the blog — a thematic index. Every post lives in one canonical place in the blog; this gathers those that belong to the topic.
This module gathers the encyclopedic crop profiles from the blog — each looks at one crop through the lens of allelopathy and companion planting. The profiles are short reference reads; the full posts live in the blog.

Allelopathy: The Secret Language of Plants
In nature, plants do not merely coexist — they communicate with one another through invisible chemical signals that can change the fate of the whole garden.

BROCCOLI (Brassica oleracea) — алелопатия
Like all members of the cabbage family, broccoli grows wonderfully in the company of dill, celery, chamomile, sage, mint and rosemary.
BRUSSELS SPROUTS (Brassica oleracea L. var. gemmifera DC)

WATERMELON (Citrullus vulgaris)
Watermelons, like the other members of the family, are protected from pests by plantings of nasturtium around them. In the planting hole, when you set out the watermelons,…
TOMATO (Lycopersicon esculentum)
Tomatoes and all members of the cabbage family repel one another and need to be kept apart in the garden. They also dislike potatoes and fennel.

Celery thrives with leek, tomatoes, cauliflower and cabbage. It and bush beans support each other. It is good to grow celery in a circle, so that its freely…

The dandelion loves good, deep soil, like clover and alfalfa. The soil around dandelions is attractive to earthworms, because this plant is…
PEA (Pisum sativum) — алелопатия
Peas grow very well with carrots, turnips, radishes, cucumbers, corn, beans and potatoes, as well as most aromatic herbs.
JERUSALEM ARTICHOKE (Helianthus tuberosus)
Also called the earth apple, it is in fact a kind of sunflower that comes from America, and its underground part was traditionally used as food by Native Americans. It can…

One of the main pests of cauliflower — the small white cabbage butterfly (Pieris rapae) — can be repelled if celery or stalk celery grows nearby…

This really easy-to-grow vegetable, gaining more and more popularity here, is one of the oldest crops cultivated in China. Planted in the autumn…
Chilli peppers (Capsicum spp.)
The Aztec "chilli," or hot peppers, were known as far back as 700 BC, but their place of origin is still a mystery.

BEETROOT (Beta vulgaris) — алелопатия
Beetroot, in all its variations (leaf, sugar, salad and others), thrives next to bush bean and kohlrabi, but does not do well next to climbing bean.
CABBAGE (Brassicaceae) — алелопатия
The family includes cabbage, cauliflower, broccoli, kale, collard, kohlrabi, Brussels sprouts, mustard, leaf mustards, even turnip and radishes.
