Growing Veg in a trough planter

I've been trying to grow veg for 2 years now (am a complete novice) in a waist height trough planter. I have tried garlic, spring onions and leeks. The problem I seem to face is that the veg grow to a certain size and then seem to stop. I've just lifted my garlic (planted in Oct last year) and all the heads were about the size of a 2 pence piece.

I am starting to wonder whether the growing medium is the problem. I have a mixture of multi-purpose compost and top soil (I haven't added anything to it). Could someone advise me what I need to grow in as I am getting to the point where I am not able to grow anything.

Many thanks.

    You might need to water more and you certainly need to add some nutrients if it has been the same soil for 2 years.

    Garlic often only grows a single bulb the first year, so try planting the small bulbs again and see what happens.  Is the soil waist deep? I have a waist high trough planter which is about a foot deep.  It is new and hasn't been used yet. If your garden soil is poor,  I would be inclined to use less of it. You will have to water sufficiently and feed.

    If you are prepared to renew your planting medium every year, with less than 12 inches depth of soil, you can produce more than you probably think.
    Obviously depends on what you wish to grow but Dwarf Beans, various salad leaves, chives,rocket, radish, Beetroot and Carrot ( the small varieties for the latter 2 ) are just some you can grow and harvest.

    I have two of these trough. one small one for strawberries and the larger one for veg, attach photos, but these were taken some time ago, I find growing root veg is not good in a trough, I have manage beetroot and radish and spring onions, but carrot and anything else not good, but have manage sugar snap peas, with support, all kind of lettuce and spinach kale,
