Sow seed spring in situ after the last frost; germination is normally very rapid, though seedlings resemble fat hen weed (PFAF, Pumpkin Beth).
Spacing/thinning
1
Space plants 15-20cm (6-8in) apart (Pumpkin Beth).
Leaf growth
3
Grows upright and bushy to 3-5ft tall; leaves harvestable as a vegetable after 7-10 weeks, with excellent heat tolerance (Pumpkin Beth).
Flowering and seed harvest
8
Flowers July to October, seeds ripening August to October; immature flower buds are the prized harvest, resembling small broccoli florets (PFAF, Pumpkin Beth).
When to pick: Leaves can be harvested as a vegetable after 7-10 weeks; the prized immature flower buds, resembling small broccoli florets, are harvested for traditional Mexican dishes. Raw leaves should be eaten only in small quantities due to saponin and oxalic acid content (Pumpkin Beth, PFAF).
Huauzontle (Chenopodium berlandieri subsp. nuttalliae) shares its genus with the already-published Quinoa (Chenopodium quinoa) but is a genuinely distinct species -- also called Aztec broccoli or red Aztec spinach.
Contains saponins and oxalic acid -- those with rheumatism, arthritis, gout, kidney stones, or hyperacidity should use caution; raw leaves should only be eaten in small quantities.
An annual reaching 0.6m (2ft) tall, flowering July-October, seeds ripening August-October, hermaphrodite and wind-pollinated. Native to southern North America, Mexico. Cannot grow in shade, requires full sun. Soil: light, medium or heavy, mildly acidic to mildly alkaline pH, prefers moist soil. Sow seed spring in situ; germination is normally very rapid, but seedlings resemble fat hen weed, requiring careful identification while weeding. Easily grown in most soils, preferring moderately fertile conditions; historically cultivated in Mexico for edible seeds and flowering shoots; potentially a very productive crop. Edible leaves (cooked), flower clusters (cooked, resembling small broccoli florets), and seeds (cooked). HAZARD: contains saponins and oxalic acid -- those with rheumatism, arthritis, gout, kidney stones, or hyperacidity should use caution; raw leaves should only be eaten in small quantities. No pests or diseases documented in this source.

Frequently Asked Questions
What soil pH do huauzontles need?
A pH of about 6–7.5. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect huauzontles?
Our data links 1 disease and 2 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
This page gives you the thresholds; the planner turns them into your own calendar. It works from what you can observe and measure in your garden rather than from dates written for somebody else’s latitude.
Science-based growing guides · Thresholds that hold in any climate
This guide states the conditions the plant itself responds to — soil temperature, frost tolerance, day length — rather than dates, because the same calendar month means opposite seasons in the northern and southern hemispheres. Anything genuinely restricted to one part of the world is named as such rather than presented as universal. Written and maintained by our editorial team against international horticultural research and extension sources.
Sketch your exact plot shape, pick your crops, and get a spacing-accurate bed layout with companion pairings and a rotation plan. Spacing, companion pairings and rotation are the same in every climate and both hemispheres — pair the layout it gives you with when to plant to set your own timing from soil temperature.
