As this is the first time, is that how to do it?
I do not like to hurt the ladies. I prefer to rejoice ...
But alas, this is not the right method!
It is necessary to wait until the seeds are formed on the stalk, in "fruits", which are kinds of capsules, which have become dry. And harvest right before it opens.
I have a hard time appreciating the photo, maybe it will still be fine and the seeds will form with what remains of "juice" ?????
The leek, like many vegetables (cabbage, carrots, celery, parsley ...), is a biennial. The first year is "photosynthesis - growth - accumulation of reserves in a fleshy root or a" pseudo-bulb "= the bottom of the swollen leaves" ...
The second year, after a period of cold (this is the "signal"), it is "to take care of producing flowers and then well-filled seeds so that the offspring is best assured".
The flower is there for fertilization; attract the browsers.
After fertilization, become irrelevant, she fades. If there is fertilization, the eggs develop into seeds and the ovary into fruit. It is understood that in botany, a fruit may be very dry (such as a grain of wheat or a bean pod matured). This can be the small black grains on the strawberries!
It is therefore important not to cut until the process of transfer and transformation of reserves from the pseudo-bulb to the seeds is not completed. The transformation aims to "concentrate" a maximum of energy in a minimum of space, so that the seed can "fly" further, while containing sufficient energy to start a plant during germination. So starch or oils or both are formed.
It is not primarily about drying, on the contrary. It is about filling !!! The lack of water, at this stage, is critical. It produces what is called, for wheat, a "scalding" = formation of small grains, not filled enough.
Once the process is finished, the seeds filled, the transformations made, the "fruit" naturally dries up. It is then, and only then, that it is necessary to harvest, finish drying and store well. Without delay, because often the "capsules" (dried fruits) open naturally or even "project" the seeds (in cardamine for example or oxalis).
Another example that shows that wanting to do in the place of nature is exposing oneself to doing stupid things!
