When & How to Harvest Leeks

Leeks can be harvested at several sizes, but timing affects tenderness and usable shank length. Pulling them carefully helps preserve the long white stem.

Leeks

How to tell it is ready

Harvest when the shank is large enough for your needs, often about 1/2 to 1 1/2 inches across, with firm upright leaves. Smaller leeks are tender, while larger ones give more yield but may be stronger and coarser.

How to harvest

Loosen soil deeply with a fork, then pull the leek straight up by the base. Do not yank from dry, tight soil, because the stem can break below ground.

Timing

Leeks usually take about 90 to 120 days from transplanting, sometimes longer for large fall crops. Harvest in cool weather from late summer through fall, and in many areas they can be dug as needed. Pull in stages as plants reach the size you want.

After the harvest

Trim roots and cut back the leaf tips if desired, but leave most of the shank intact. Shake off excess soil and keep unwashed leeks cool until cleaning. Refrigerate promptly for best quality.

Tips

Hill or blanch plants during growth if you want longer white shanks. Harvest smaller ones first to give the rest more room to size up.
