FAQs
When is the best time to sow Leek 'Stromboli' seeds?
You can sow indoors from January to February or outdoors from March to April. Planting out occurs from April to May.
How far apart should I plant the leeks?
Plant seedlings 15-20cm (6-8in) apart in rows that are 25-30cm (10-12in) apart.
How do I get a long white stem on my leeks?
To ensure a long white shaft, draw soil up around the plants as they develop. This process is called blanching.
What temperature is ideal for indoor sowing?
An ideal temperature range for indoor sowing is 10-15°C (50-60°F).
Can I leave the leeks in the ground over winter?
The 'Stromboli' variety holds well in the ground until needed, suggesting it has good overwintering potential for harvest flexibility in milder climates, though protection might be beneficial in harsher conditions.
What type of soil do leeks prefer?
Leeks prefer fertile, well-drained soil. Amending the soil with compost before planting will provide essential nutrients.
Troubleshooting
Seeds fail to germinate
Ensure seeds are sown at the correct depth (1cm) and that the soil is kept consistently moist and at the appropriate temperature (10-15°C for indoor sowing).
Leeks are thin or have short white stems
Ensure regular feeding and consistent watering. Gradually draw soil up around the base of the plants as they grow to encourage blanching.
Pests on leaves
Inspect plants regularly. Handpick larger pests or use an appropriate organic pest control method if infestation is severe.
Slow growth
Check soil fertility and consider applying a balanced liquid fertilizer. Ensure adequate sunlight and consistent moisture.
