Ah, well. Despite our attempt at successional sowings, it seems that we have a temporary lack of lettuce.
The last of our lettuces bolted ( the final poor specimen can be seen in the bottom right of the picture above ) and had to be pulled out. The romaine seedlings that we planted out a few weeks ago are still a few weeks from harvesting. We picked the last of our second crop of mangetout last weekend, cut the plants off at soil level (leaving the roots to enrich the soil with nitrogen) and planted out more romaine lettuce seedlings in their place, but they still have a way to go as you can see above.
Our most recent sowing of looseleaf salad bowl lettuce is still a tray of seedlings too. On the positive side, in a few weeks time we should be back to harvesting both types of lettuce thick and fast! In the meantime, we had to buy lettuce for the first time in months. Next year: must try harder.
