onion weed seed

Three-cornered Garlic (Allium triquetrum) has bulbs, a triangular stem and a strong odour.

Many attached spirally at base. Shorter than flowering stems.

Pistil – 3 carpels.

Asphodel (NZ)refers to the genus name.

Spinnaker at 100 mL/ha in autumn provides 50-70% control of Dune Onion Weed seedlings, reduces grasses and has little effect on legumes. Higher rates only improve control marginally and cause more damage to pasture grasses.

Hollow-stemmed Asphodel (Europe)

Eradication will take a number of years because of the dormant seed bank in the soil.

Provides pollen for bees.

Tends to occur in disturbed or overgrazed areas.

Onion weed seed

Type: Perennial grass weeds
Size: 8-12″ inches tall
Where it grows: It can be found in many gardens and lawns,
Appearance: Wild onion has round long leaves.
Control: Pre-emergent and a post-emergent. To manually remove it, dig the clump out of the ground with a spade or trowel. Throw the entire clump away. Then spray with an on-contact killer in the hole.
Notes: Wild garlic can also spread by producing bulblets. These bulblets become new plants, thickening the patch. Frequent mowing will slow the spread because the plants will not have sufficient time to flower and go to seed.

Mowing will slow the progression of these weeds because both wild onion weeds need blades for photosynthesis to occur. And mowing before the plant flowers and sets seeds will also slow its spread, so if you prefer non-chemical controls, “mow, mow, mow” your weeds.

wild onion weedsCan You Eat Wild Onions?

Wild onions is the untamed cousin of the garden variety onion we use for cooking, and just like those from the store, or those we grow in our home gardens, the “wild ones” are edible. However, use extreme caution about eating anything plucked from your lawn (same as with mushrooms) as there are potential hazards, especially if chemicals were applied to your lawn or flower bed.

These weeds are strongly scented, perennial plants or weeds found in most parts of North America. They grow in sun or shade, emerge in fall, and grow throughout the winter. They flower in spring, spread seeds, and then go dormant until cool weather returns. Until they go dormant, wild onion weeds presence will be announced by the odor of onions when the lawn is mowed those first few times in late spring.
