We planted a range of lettuce seedling varieties to see the best options for winter supplies in 2014, Auckland, New Zealand.
Best by far is ‘Lolla Rossa Foxy’ with crinkly broad soft leaves grading from bright green to brown edges [back row of garden bed].
The cos [front row, 2nd from right] were a sad second last. Last were red cultivars which rotted through the stems and died before producing edible leaves [they were in the middle of the front row].
Oakleaf lettuce forms are slowly growing. Direct seed sown Oakleaf lettuces are doing better than seedlings transplanted.
All were covered by a plastic poly tunnel and treated equally.
This garden is near the harbour and soil is clayey with bought compost over the top. Garden bed faces north-west, is brand new, raised, and beside a fence.
Different varieties really do provide different outcomes depending on climate and soil. Even if I prefer one type of lettuce, I may have better production from a less favored variety when my favourite dislikes the conditions. I love growing a range to see which do best for us.
