The vegetable garden without getting tired

[Moindreffor]

Yes, that is what I had trouble explaining to a friend who was also convinced that the ice did not go below zero!
It is indeed necessary to consider things from the dynamic angle: the phase transition releases the latent heat of the water and maintains the temperature around zero as long as the supply of water makes it possible to compensate for the caloric losses due to the environment. colder...
In any case, ice is a state of matter (water) and does not correspond to a defined temperature (outside of its upper limit), any more than water in liquid form.

more simple the change of state water (liquid) towards ice (solid) is done at constant temperature we will admit 0 ° C so as long as there is a water / ice mixture the temperature remains at 0 ° C as soon as there is only one physical state ice the temperature can drop

salt water freezes between -7 ° C and -14 ° C depending on the salt concentration, which is why we put salt on the roads in winter

[stephgouv]

No, he only understood a quarter!

a) the flowers freeze around - 1 to - 2 ° C

b) the water-ice mixture is, by definition, at 0 ° C [well if the water is pure, but don't nitpick], therefore above this limit ... It is a physical constant.

c) consequently, on condition of sprinkling CONTINUOUSLY and SUFFICIENTLY so that there is always liquid water which turns into ice, in fact, the flower is protected from freezing !!!

Even if we find it wrapped in a "cocoon" of ice (and liquid water around!) ...

It's pretty amazing, but true.

But the ice alone drops to much lower temperatures. So pouring water and letting it freeze is useless! A block of ice removed from the freezer is at - 18 ° C.

No, I was the one who only retained a quarter.
He explained well what you wrote to my mother-in-law. My memory failed me ... This is the reason why my mother-in-law never did that because for her it was unfeasible!

Small practical question to the experts:
Should I repot the cauliflower, Broccoli, Bxl cabbage and red cabbage plans? Or can I leave them like this until transplanting in mid-May?

It is snowing this morning at my house at an altitude of 450m.

[Doris]

I am not an expert but today I will repot the cabbage in individual pots, my goal being to have plants of a certain size before putting them in the garden with its slugs

[Did67]

Where are they there? And where are you, I don't remember?

They are hardy or fairly hardy plants. I do not have all the "minimum temperatures" that they withstand, but we must be around - 5 ° C.

At my house too, snow ...

[stephgouv]

I'm about 30km from where you came to do your conference near Stavelot (B).

The plants have been sown in pots (1 seed / bucket) see below and are stored in the veranda (18 ° c for now)

Here broccoli

[Did67]

They are very well ! No need to replant while they are in pots of sufficient size ...

The veranda, a tool with which many Belgian houses are equipped, and ideal for that!

The vegetable garden a bit like in a snow globe that we just shaken.

Tombeuuuh the snow

[GuyGadebois]

It was the same with us last Thursday.

[stephgouv]

watch the videos of the working fraternity, the penultimate I think, the guy shows how he made himself a tool for transplanting very small seedlings with a piece of electric cable
I use a chemist's spatula, professional deformation requires

I watched the video the day before yesterday and said to myself: But I have a tool like in the video! Here it is:

Potting tool

So, I got to work:

The equipment is ready!

The buckets are ready

The result

I even allowed myself to try a sweet potato
