Brassica oleracea var. palmifolia
To keep your kale growing after harvest, you should harvest in layers.
• Pick leaves from the outer layer first then move to the inner leaves. Be sure to pick the biggest and lowest leaves first.
• Harvest leaves one at a time, leaving the central stalk so new leaves will grow.
• While you harvest, remove any yellowing or discolored leaves so that new, healthier leaves will be encouraged to grow.
