Overview

Tree spinach is wind-pollinated but does not require specific pollinators. Self-pollination is possible.

Notes

Since pollination occurs via wind, no pollinator insects are required. Cross-pollination with other Chenopodium species is possible but not necessary for species preservation.

Use & storage

Tree spinach Use & storage

Harvest

Harvest leaves and young shoots continuously from June to October. Regular cutting encourages regrowth.

Storage

Refrigerator (short-term)

Storage life

3–5 days at 4–7 °C and high humidity

Harvest

Harvest leaves and young shoots continuously from June to October. Regular cutting encourages regrowth.

Processing

After harvest

Store harvested leaves and shoots immediately in a damp cloth or plastic bag in the refrigerator. Do not wash until shortly before use.

Edibility & safety

Tree spinach Edibility & safety

For people

In brief: which parts are edible, which parts remain risky, and whether raw consumption makes sense.

Edible parts:leaves, young shoots
Caution parts:mature seeds (may have a laxative effect in large quantities), old, woody stems
Raw consumption:Yes, leaves and young shoots can be eaten raw but taste more bitter than after blanching.

Safety notes

Tree spinach contains oxalic acid, which in large quantities can inhibit mineral absorption. Harmless in normal, moderate consumption. Oxalic acid content can be reduced by blanching.

Animal safety

For animals, the specific plant part matters here: some parts may be suitable, while others should be avoided. At least one critical rating is listed for 11 animal types.

Animal safety by plant part

Each row shows which parts are more suitable and which parts are critical.

Companion animals

Dog icon for animal safety ratingDog

Leaves (in small quantities, cooked or blanched), young shoots (in small quantities, cooked or blanched)

Mature seeds, old, woody stems, all parts in large quantities

Risk factors

Consumption of large quantities, consumption of seeds or old stems, dogs with kidney issues

Symptoms

Gastrointestinal upset (vomiting, diarrhea), with large quantities or chronic consumption: inhibition of mineral absorption

contact a vet if symptoms appear

Tree spinach contains oxalic acid, which is harmless in small quantities but can cause problems in large amounts or for sensitive animals. Leaves and young shoots can be offered in very small, cooked or blanched quantities as an occasional treat. Mature seeds and old stems should be avoided. Blanching reduces oxalic acid content.

Risk factors

overconsumption, consumption of raw plant parts (higher oxalic acid content), small animal size

Symptoms

gastrointestinal upset, diarrhea (especially from seeds), kidney problems (with chronic intake)

contact a vet if symptoms appear

Tree spinach contains oxalic acid, which can be problematic for birds, especially small species like budgies, in larger quantities. No specific safety data for budgies is available. The seeds may also have a laxative effect.

Symptoms

Gastrointestinal upset, Diarrhea (if seeds consumed in large quantities), Inhibition of mineral absorption (with chronic high consumption)

contact a vet if symptoms appear

Tree spinach contains oxalic acid, which in large quantities can inhibit mineral absorption. Mature seeds may have a laxative effect in large quantities. Leaves and young shoots can be offered in small amounts as an occasional treat, preferably blanched to reduce oxalic acid content. Not suitable as a primary feed.

contact a vet if symptoms appear

Tree spinach contains oxalic acid, which can lead to kidney problems and hypocalcemia in goats if consumed in large quantities. Although described as edible for humans, there is no specific data on its safety for goats as a forage plant. A conservative classification is therefore warranted.

Symptoms

Weakness, tremors, ataxia

contact a vet if symptoms appear

Tree spinach (Chenopodium giganteum) contains oxalic acid, which can be toxic to cattle in large quantities, especially if consumed as a significant portion of their diet. Other species in the Chenopodium genus are known for accumulating oxalates and nitrates, which can lead to poisoning in cattle. Feeding is not recommended.
