    How important is the changing soil? I am going to install a 10x8 Rhino greenhouse in the next couple of months and while it will have two lots of staging on one side with gravel underneath, the other side is still undetermined. I was going for soil but then read about pests etc. and since it was mainly for tomatoes in summer/salad leaves in winter, figured I would not be best doing this since I wouldn't be rotating much.

    I have since thought gravelling it and growing things in containers leaving no raw soil in the greenhouse. If soil is a better growing medium, it may be I need to have soil and go to the effort of changing it every year but seems a hassle.

    Has anyone learned any lessons about this?
    Thanks,
    Neil.

    Depends really on whether you are planting directly in to the greenhouse soil or not. For most veg like tomatoes I mostly use bottomless pots which the plants can them root through in to the soil below ( I use the Morrison 10 for a 1 ones and cut the bottom off) - if you were growing directly in the greenhouse soil I'd be inclined to plan on swapping some of the soil out every couple of years.
    Of course if you have a very large GH or PT you can rotate the crops round a bit and so try to avoid problems that way.

    Hi Nick, thanks for the reply. How does a bottomless pot prevent changing soil? Are pests mostly likely to occur in the soil/compost in the pot rather than in the soil where the roots are?
    Thanks,
    Neil.

    Never had any pest problems growing in the greenhouse soil, providing you do crop rotation, should be fine. As for soil replacement, I don't do it as such, what I do is use some of the soil in winter topping up raised beds, then add compost and manure in the greenhouse, only remove about 3 barrows full each year from a 12 x 8 Rhino.

    I've got a 20x8 Rhino - I grow toms both sides every year. I grow in the ground. I take out some soil from each of the borders (not much really) like Burnie, just a few barrow fulls from each side - I find it heavy going. But when planting in I dig a hole and chuck that soil outside into a bed, then put a spade ful off compost in the hole before my plant goes in. I feed well, the ground also gets BFB and a layer of compost.

    I'd go for growing in bed soil every time. The problem with not growing in soil is that you lose useable growing height because of the height of the pot and the sun heats up the sides of any pots making them dry out faster.
    When growing in bed soil you don't necessarily need to water plants every day (or even twice a day when using pots) so you get consistent growth and avoid the likes of blossom end rot on tomatoes.

    Watering is major for me - I'm on a meter As snadger says when growing in the ground you don't have to twice a water during the hot weather. Pots are thirsty! I mulch my borders with newspapers and water into bottles dug into the ground.

    I just love growing in pots and raised tubs as I find it far easier to control the sub contrate I grow in and ease of giving water and fertilisers when needed

    So made the decision, one central path made of slabs, then both sides filled with "Bark Chipping's" one side for pots and tubs where I grow my tomatoes and chilli's

    The other to whack in the staging for firstly the "Grow Beds" which I grow an abundance of crops in through the year and change the top half of soil with my own made compost mixed 50/50 with perlite to aid drainage, and the top shelf is just awesome for bringing on my seedling once all threat of frost as passed

    Again having to work from my iPad and have better photos on my "Lappy" but sure you will get the gist

    Works just well for me!
