Early Giant Leek (95 Days)

Leeks have a more delicate, sweet flavor than onions and can grow into incredible sized stalks when supplied with lots of organic matter and water. In the north we usually start our leeks indoors then transplant outside to give them a head start but this season we direct seeded this variety. We  thinned out the row, used all the tender, baby leeks up and by early September we had 2” sized stalks.   

200 seeds

Please note that germination rates for alliums (onions/shallots/chives/leeks) decline rapidly. We strongly encourage you to purchase new seed each growing season.


Allium ampeloprasm

Germination: 5-10 days

Germination Temperature: Optimum soil temperatures 60-75ºF. 

Seed Sowing Depth: 1/4" deep

Sowing Indoors: Start 8-10 weeks before the last frost with soil temperatures 60-75 ºF. Sow in flats 1/4” deep, 1/4” apart. Transplant seedlings out mid/late spring, 4-6” apart. Liquid fertilize seedlings every 7-10 days. Seedlings size should be about a pencil-thick at transplanting time.

Sowing OutdoorsEarly to mid-spring when the soil temperature reaches at least 55-60 ºF. Sow 1-3 seeds per inch, thin to 4-6” apart. 

How much does a packet plant: 25-30 foot single row  

Harvest- Start harvesting baby leeks at 1/2” diameter and leave some for a larger end of season harvest.

Tips-  Needs fertile, well-drained soil. Amend with compost or apply organic granular fertilizer. Adequate water is very important for optimum growth, 1" per week. You can plant leeks in a trench and as the plants mature, fill in around them to assist in blanching.

very nice leek for winter storage

We have grown Early Giant Leeks from Pinetree for several years, planting in flats in early spring, and growing out until being kept under row cover until harvest, right before the ground freezes,( hopefully, ha ha), and stored in our root cellar. I brought in a nice handful this morning for lunch soup, February 19 and they are storing quite well.

Best I've tried

Planted 30 cells to get 24 plants. Got 29 which all did well and are now in the garden. I have tried seed from three other sources and none of them did well. Very satisfied with the seed from Pinetree.

Early Giant Leek

The leeks are up and looking good, however it is only April so I will see, but so far they look good.



Hobby Gardener: Good leek. Had good germination and great success rate. About 25% ended up very big. The others were decent size. This could be due to a number of factors (and that I had a 12 year old help me plant them). I started them indoors then transplanted them outdoors to a shallow ditch in my raised beds. Overall, happy with them.
