Grow bag advice

  • I agree better to put compost in big pots. If you have to use a grow bag, cut in half , standard grow bags are not deep enough.

    Many thanks, what size pots would you recommend for tomatoes that will in my greenhouse. Straight compost, or some gravel at the base for drainage?

    12-inch pots maybe for tomatoes maybe? I wouldn't bother with the gravel. It's keeping them watered several times a day that's the problem, rather than drainage! I think as well to have the pots in some kind of tray, so you can have some extra water in the tray to keep them going for a while (and stops your liquid-feed from escaping if you add more than the compost can absorb).

    For tomato liquid feed I just use whatever I can find that's not too pricy. You might have gathered that I'm not a big fan of brands when a cheaper version will do the job.

  • Yes 10-12 inch pots, gravel optional if growing outdoors on a patio or similar the extra weight might be useful., to keep them upright.

    Thansk for the advice, will be in a greenhouse.

    This may be a really stupid question, so apologies.

    When people talk of size pots is that depth or diameter?


  • Diameter.

    The only stupid question is the one you don’t ask 😉

    Just as a guide the B&Q multipurpose compost in 125lt bags is the cheapest you can buy anywhere (well that's what I found after a couple of months scouring the internet). I've had real good success with it and am going to grow potatoes in it this year after beefing it up with BFB and a bit of chicken manure pellets. It's definitely worth a look

    Many thanks - Is Verve their own brand?
  • Yes verve is their own brand.  They do a peat free version which we should all be aiming for.  The GW mag has had a lot on this issue recently.  I surprised  we haven't had more discussions on this.
