Troughs for tomatoes.

Hi all, i've been hardening off my tomato plants, and want to plant them into troughs, i've got three troughs, approx three foot long, by about 8 inches deep and wide, i intend putting three plants into each trough, but i'm wondering if the troughs are deep enough, any suggestions?

    I always plant mine in deep pots ( the ones some supermarkets sell flowers in). They then produce more roots from the buried stem making them more sturdy. It helps when they become heavy with the fruit.

    Aaah thank you Sophie, that was the bit i was wondering about, if they were deep enough for the roots.

    I prefer to grow mine like Sophie (unless they're in the ground).

    That said - some people seem to have a lot of success growing toms in grow bags. I've never done that because I couldn't work out how there would sufficient depth of soil to keep the plants stable. But I guess there is quite a lot of room for sideways root growth.

    I would think the troughs might be a bit too restrictive on all counts.image

  • I agree with previous posts I grow mine in large tubs the bigger and deeper the tub the more tomatoes I get

    Thanks all, I'll go shopping for some big pots at the weekend.

    Brickman, fill the trough with compost. Those pots should then fit in the top of the trough, set one plant to a pot filling just halfway, three shoult fit nicely though two would be better. Water the trough and keep the pots just damp, providing the holes in the pot are big enough the roots grow through. As the plants grow top up the pots with fresh compost for extra feed though tomato feed will still be needed.

    I grow my tomto's in twelve inch pots on a gravel bed that holds water, never failed in thirty five years where some around have lost the crop, careful feeding watching the watering and making sure of an ambient temperature takes time but worth it.

    Which ever method you choose, whether it be pots or growbags, tomatoes are greedy things and need a lot of room for their roots.

    I have adapted the ring culture method by using large pots instead of a ring and growbag.

    Not sure it would be good for bush tomatoes but it certainly works for the tall things that take over the greenhouse.

    That;s the size of trough that I use - three plants per trough.  I've done it for years, and get more tomatoes that I can eat fresh - but they make wonderful passata or chutney!.

    The difficulty may be in supporting them.  I have found that three canes per trough about 4ft high, linked at the top with square-lashed cross pieces (and the top canes link each of the troughs, too) together with short angled braces at the bottom, is more than adequate.  

    I have a picture somewhere to show what I mean - if I can find it, and then work out how to post it!
