Leek

Planting Time Leeks thrive in cool weather and can be planted in early spring or mid to late summer for a fall harvest. They handle cool nights and light and appreciate steady, mild temperatures. Starting seeds indoors eight to ten weeks early gives them time to size up before moving outdoors. Once planted, they grow slow and steady like a dependable ranch hand.

Depth & Spacing Transplant seedlings deeply, burying part of the stem to encourage long, white shanks. Space plants six inches apart in rows twelve to eighteen inches. Leeks grow upright and polite, never sprawling or causing trouble. Hilling soil around stems as they grow produces tender, blanched stalks prized in soups and stews.

Soil & Fertilization Leeks prefer rich, well drained soil with plenty of organic matter. They are heavy feeders and benefit from compost or balanced fertilizer. Avoid letting soil compact, as tight soil restricts growth. Loose, fertile soil builds thick, flavorful stalks that make you feel like a gourmet chef, even if you are cooking in cowboy boots.

Watering Needs Keep soil consistently moist to encourage steady growth. Dry spells stunt leeks and toughen their outer layer. Think of watering like topping off a stock tank-regular, reliable, and never too much at once. Mulch helps maintain moisture and reduces weeds.

Sunlight Requirements Leeks grow best in full sun but tolerate light shade, especially during hot afternoons. Too much shade slows growth and results in thin stalks. Sunshine gives leeks the energy to bulk up and develop their mild, sweet flavor.

Harvesting Harvest leeks when stalks reach at least one inch thick, though smaller ones are tender and tasty too. Use a garden fork to loosen soil before pulling, as leeks can grip the ground like a stubborn mule. Trim roots and tops for storage. Fresh leeks keep well in the fridge for weeks.

Captain Greenhouse Tip For longer, whiter shanks, hill soil or mulch around the stems several times during the season. Leeks love cool weather, so consider a fall crop for the sweetest flavor. And remember-slow and steady wins the race. With patience, leeks reward you with flavor worth bragging about.
