    As taught to me on my horticulture course.

    Plants need their soil to have:
    25% air
    25% water
    45% soil [equal parts sand, silt clay]
    5% organic material

    With compost, that organic material is very high - hence having to feed as in soil, the nutrients ideally are in the clay.

    So, if your pots are kept wet all the time, where are they getting the air from? They need to be watered but they do not need to be constantly wet. There should be enough in the compost in weather like this to sustain the plant for a few days, if you are watering every day then they aren't drawing any air into the soil. Unless they are water plants like celery of course. But anything else - give them some air!
    that is very interesting... i love this forum because there is actually a lot to learn and not only people thought... this make sense.. i'm worry that they didn't get enough water but i drown them

    this is wat i do outside when i plant them in the final position... my finger are so fat (my fiancee call them sausage finger) that if i poke the soil in the 3" pots it will look like a squirel dig home in my pot ... plus i end up to compact the soil...

      Basil really is Mediterranean, and needs it warmer than your blowaway is, I suspect

        My fingers must be a bit more dainty . You don't need to prod your finger in like you're poking someone in the eye, just scratch your way in gently like a little mouse, replacing the soil after yourself. It works for me anyway, that's all i'm saying.

          Whilst there is no doubt about what everyone including me is saying about overwatering killing seedlings.

          A conumdrum for me as always been hydroponics just why don't their plants die?

            With hydroponics, the plants aren't constantly in the water are they? I thought that the solution was pumped round, sort of washing over the roots rather than just sitting there. Never used that system though, so I may well be wrong

            Edited to add: There seems to be many different forms of hydroponics. Some simple explanations and diagrams here: http://www.simplyhydro.com/system.htm They all seem to involve air though

              Thanks for that link Sarah, simple and very informative. Question answered the roots do not sit in liquid 24/7.

              Thanks Colin
