Frequently Asked Questions


Why are my Allium porrum (leeks) getting yellow streaks or wilting, and what should I do?
Yellow streaks and wilting in leeks are often caused by leek rust or onion thrips; both can be worse in crowded beds with poor airflow. Remove and destroy heavily affected leaves, then spray with an appropriate product labeled for leek rust/thrips and rotate away from all Allium crops next season. Keep foliage dry by watering the soil only and space plants for airflow.
How often should I water Allium porrum during the main growing phase, and what soil moisture target should I maintain?
During the 60–90 day growing window, keep the soil consistently evenly moist—about 1 inch (2–3 cm) of water per week total from rain and irrigation if the weather is dry. Water deeply to reach the root zone, then let the surface dry slightly before watering again to prevent rot. Mulch around leeks helps keep the soil moisture steady so the white shanks develop well.
How can I tell when Allium porrum (leeks) are ready to harvest?
Harvest at about 95–110 days when the leek has a firm, thick stem (white shank) and the base sits at least several inches deep with good blanching. You can harvest earlier for smaller “baby” leeks, but full-size leeks should have sturdy, tight leaf bundles and minimal thinning at the base. If frost threatens, lift and harvest before repeated hard freezes for best texture.

Sweet, mellow Verina leeks arrive with a tender, ivory heart that melts into a gentle, garden-fresh flavor—never sharp, always inviting. The pale shafts are crisp and fine-textured, with a graceful taper and a clean, upright habit that makes them a joy to grow and to savor in hearty, comforting preparations. Ideal for steaming, braising, soups, and gratins, Verina brings a refined leek character that turns everyday dishes into something special.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 28°F before moving outdoors. Harden off for 6 days first.

Expert Note

For fall leeks, start indoors early enough to transplant when daytime temps begin cooling, then keep the soil consistently moist for thickening white stems.
