Try to provide some shade to prevent them 'bolting' to flower and seed in the hottest months. Harvest when lettuce hearts are large, full and tight. For best results, use liquid fertiliser every two to three weeks.
🌱SEEDLING HEIGHT| 15cm-20cm including the root system
🥗HARVEST| 8-12 weeks, depending on location & weather conditions.
🌡️CONDITIONS| Sunny position, well-drained, non-acidic soil rich in organic matter. Shallow rooted so water frequently in hot or windy weather to prevent bolting and bitter leaves.
I've never successfully grown iceberg until now, now I'm giving them away we have so many! The seedlings from QPS have all been amazing, they arrived safely and I am already planning my next purchase.
Just picked the first lettuce , I will be eating salads all Feb with the inclusion of fennel fronds, celery choy sum, that I ordered. Organic sealings delivered to your door ! Taking all the troubled work out of propagation. Thanks Jye , I look forward to my next visit and order.
