Tomato

Solanum lycopersicum L.

Botanical family: Solanaceae

Queen of the summer vegetable garden, the tomato loves warmth, a rich soil, and watering at the base. Self-pollinating: each flower can fertilise itself, but its pollen comes out better when the flower vibrates, in the wind or when bumblebees and other buzzing bees visit; those visits can give heavier fruit (Cooley and Vallejo-Marín, 2021). Under glass, where the air moves little, the trusses may need to be vibrated.

Tomato is at the heart of a permaculture guild.View the guild
Exposure

Full sun

Soil

Rich, well-drained

Watering

Regular (avoid the foliage)

Hardiness

Frost-tender: the slightest frost damages it; grown as an annual in our climates

Frost-tender in your zone

Pollination

Self-fertile: the flower fertilises itself when wind, a light shake or a bumblebee releases its pollen

One plant is enough for a crop

Role in permaculture

Central plant of the tomato guild. The neighbouring basil is reputed to hinder aphids through its volatile compounds.

Good companions

Harbour beneficial insects (insectary plant)

Suppress some soil nematodes (dense planting, before the crop)

Trap plants (variable effect, need watching)

Aromatic: scent said to confuse pests

Poor companions

Same family: shared diseases and pests

Allelopathy, reputed or observed: may slow some neighbours

Traditional avoidance (antagonism not demonstrated)

Insects attracted or useful

Known pests & diseases

Precautions & contraindications

The health benefits exist mainly within an overall diet, not as a 'medicinal plant' in its own right.

In the kitchen & the apothecary

Where to find tomato in preparations: recipes and traditional herbal teas.

Family behaviour: Solanaceae

In general, Solanaceae are very hungry for nitrogen and prone to blight (Phytophthora infestans). They like heat, sun and a rich soil.

Nahuas (Mexica) of central Mexico, as recorded by friar Bernardino de Sahagún · Valley of Mexico (Tlatelolco market), 16th century

Our word 'tomato' comes directly from Nahuatl, the language of the Nahuas. They distinguished the xitomatl, the large fleshy fruit, our tomato, from the tomatl or miltomatl, the small green husked fruit now called tomatillo. The fact is attested: in his Historia general de las cosas de Nueva España (Florentine Codex), Sahagún, who worked around 1560–1577 with Nahua informants, describes the tomato seller and lists the many varieties sold at the market. The French form 'tomate' passes through the Spanish tomate, itself borrowed from Nahuatl: the etymology is thus a direct linguistic trace of this culture, and not a late reconstruction.

Bernardino de Sahagún, Historia general de las cosas de Nueva España (Codex de Florence), livre X (le marchand de tomates) et livre VIII, vers 1560-1577 ; Nahuatl Dictionary (Wired Humanities Projects, Université de l'Oregon), entrée « xitomatl », qui cite l'attestation de Sahagún.

A solid fact: the lexical borrowing Nahuatl → Spanish → French and Sahagún's attestation are well established. Caution, without essentialising 'the Aztecs': Sahagún's work is a colonial source co-produced with Nahua scholars, precious but filtered through the Franciscan gaze. The distinction between xitomatl and tomatl is moreover often blurred in popular accounts. No medicinal virtue is put forward here.
