Surprisingly, this is the most frequently asked question. I have cut many Balcony to Table Lettuce plants and yes, the leaves do grow back again. The new growth is not as full and bouquet-like as the original. I have tried this indoors, outdoors, winter, summer and even in moderate to low sunlight. Be sure to cut the leaves above the base. This will allow the new leaves to grow. Patience is required for this strategy. It does take several weeks to re-grow.
As a struggling small business owner, I would prefer the “cut and come back” method where customers just come back to buy more Balcony to Table Lettuce. These valued and impatient customers can reuse the organic soil in their garden or in their indoor plants.
