How to grow & propagate wild garlic / wild onion
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate wild garlic / wild onion
The onion family is grown three ways: from seed, from little bulbs called sets, or — for garlic and shallots — by breaking apart a bulb and planting the individual cloves. Garlic and perennial onions are the easiest of all: plant a clove in fall, harvest a whole head the next summer, and save your biggest heads to replant. You never have to buy it again.
Growing wild garlic / wild onion in Texas
Give it full sun to part shade and most soils soil. Match the spot to the plant and most of the battle is already won.
Because it's a perennial, the work is mostly up front. Get it sited and established and it comes back on its own year after year — one of the best returns on effort in the whole garden.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly forage spring greens & bulbs before you're harvesting. The part you're after: leaves, bulb, bulbils, flowers.
Making more for free
Every seed we sell is open-pollinated, which means you can save your own from the best plants and it'll grow true next year. Let a few of your strongest plants finish and go to seed, dry it fully, and store it cool and dark. That's the whole point of heirlooms — buy once, grow forever.
Before you forage it
A safety note, because this one grows wild: positive identification comes before anything goes in your mouth or your medicine. Confirm it on several features — leaf, stem, flower, smell — not a single resemblance, check the lookalike warnings, and never forage from roadsides or sprayed ground. When in doubt, leave it out.
