    I refer you to my earlier posts @oker. You're overthinking it. Just mix it up.
    As long as there's a decent amount of soil, and it isnt alkaline, pines will grow in it.
    Soil based mediums prevent too much drying out, which is what happens if you use compost alone.
    That's even more important when it's a very large specimen in a pot.

    Oh my god..... Right now I really cannot know which one. Some one said here john innes n. 1, some one said n. 2, and some one said n. 3. So, 1 or 2 or 3???

    The pine will come together with this palm, little tree with the lemon color and these little roses. I will make a larger pot to put these everything together : 145 cm x 115 x 55. This is the maximum size I can do. No larger space for this. No little legs for the pot. I will make the pot by myself, so, the pot will have no bottom like this on the picture. Directly on the pavement.

    I am worried the pot with no bottom will be too closed with the pavement and the water will not be able to go away. So, you think, I should not be worried it will be too wet when it is raining?

    I think I'm boughing out of this thread now. 
    You need to look at how plants grow @oker. A plastic bag isn't suitable. Those plants together in that photo aren't going to be happy for any length of time. 
    The 'little tree'' is indeed a tree, it's a conifer. 
    You need proper, sturdily built containers - with bases - to grow them, and learn which plants will grow together in the same space. The bases should have plenty of drainage holes, and be raised off the ground to allow excess water to get away as @philippa smith2 has explained.

    How can you possibly expect to grow plants like this in one container ?
    I have Pinus nigra in my garden ( still young @ 30' high and 20' across ) , 25-years on .
    The 'little tree' looks like Cupressus macrocarpa 'Goldcrest' ; these attain similar proportions in half the time .
    Your palm , from what I can make from the indistinct imagery , is not one of the approximately 2-species which tend to survive in the UK (trust you're in the UK)?
    Maybe time to re-think your planting strategies ?

    The palm looks like Trachycarpus to me - perfectly hardy. I have one roughly the same size in a pot that's about 30cm in diameter.

    I would plant the palm and the pine in separate containers though. 

    I would recommend going for John Innes no. 3 if you're unsure. It's what you would use for most shrubs and trees that are going to be in their pots for a long time.

    There isn't 'one correct answer' to your query - that's the problem. I'm suggesting JI no.3 as it's a simple solution. In reality I tend to improvise my potting compost for cost and convenience, for example mixing cheap multipurpose compost with soil and sand to make soil that is similar-ish to JI no.3. But that's a bit complicated to get across so I would say stick with JI no.3 as it's fit-for-purpose straight out of the bag.

    Some people here say a pine needs peat, doesn't it?
    Is in the John Innes no. 3 and 2 and 1 a  peat? If yes, in which one(s) mostly.
