Chickweed can withstand temperatures as low as 36 degrees, but it needs sunlight and fairly dry soil (after germination). Pick an area in your garden that gets plenty of sun. It is OK if there is light shade; the plant can tolerate it.
Chickweed needs rich soil. Till the land and add high nitrogen fertilizer before you plant.
Plant seeds 12 to 24 inches apart. Cover with 1/8 inch of seed-starting soil.
Allow seeds two to three weeks to germinate. Water so the soil stays moist.
They only need to be watered in case of a drought in high summer heat.
Remove dead flowers and prune plant. Chickweed will bloom in the spring of the second year after planting--and every following year.
If you want more, you can propagate by using cuttings and planting them in the spring.
