Revitalise spent compost - how??

Hi all I am thinking ahead for next year.... This year I had tubs with potato, some French beans, carrots, tomato. 

 

what I need to know is how to revitalise this for next year???? The carot bed was a big cement tub 4ft x2ft by 2.5ft deep. This was spent compost, new compost and sand. I dont really want to waste this mix especially as the sand sealant cheap. What should I do??

the beans, potato and soon I will have tomato spent, how can I revitalise???

  • I don't know if this will help, but when we dig out a potato bag or tub, we either put the compost on the soil as a mulch, or put it in the compost bin.

  • Thanks verdun. Yes only carrots and they did Well and didn't suffer with pests. I really hoped I could use this for my carrots again but maybe not you think??

    I know I want potatos carrots tomato and climbing French beans in tubs next year. Can any of those go back into this compost if I mix together and fertilise with ??????

     

  • If really set on growing carrots there nxt yr, you could try interplanting them with onions, chives, garlic or the like, but most advice, as Verdun's, is not to plant a crop in the same soil two yrs in a row. This is how crop-specific pests build up in the soil. Avoid growing plants of the same family in the same place again the next yr.  If you are growing all the same plants again, and re-using the compost/soil, use a crop rotation system as you would for beds.  re-vitalize the compost as verdun suggests, then put the plants into different pots than last yr.  Remember that toms and pots sre in the same family, so don't put a tom into last yrs potato container unless you have completely changed the compost and cleaned the pot.

    However, having said all of this, all of my fruit and veg growing used to be in containers as i had a concrete yard. I used to mix in some home-made compost and a little growmore each yr, then feed as neccessary and never had any probs.  Containers can be more work in watering and feeding, but easier to control pests and diseases.  I am finding more probs in my raised veg beds than I ever did with growing in containers.

    I wouldn't put tomatoes into old compost. Replace the old stuff before using it for them. Old compost is great for putting on ornamental areas as an extra mulch or for bulking up any new areas for planting shrubs or perennials. I'll be using mine for that image

    And somewhere on the hill
    Inside the past we hear the bells
    Catching only parts of thoughts
    And fragments of ourselves
    Till we begin
    Again


  • Best way to dispose of old compost is to add it to a compost pile as you are putting in cuttings etc.

    its full of good bacteria and can add to you compost pile.

    Also you could use it on a lawn as a top dressing.

     

  • Think the carrot sandy mix will be bagged up over winter and used for potatos when I have added some fish and bone stuff I bought today.

    the beans compost will go for next years carrots.

     

    the potato and tomato will mulch round my beds?? How does that sound? Anything that is left I will add more new compost to and use for French beans. 

  • Sounds good to me, 'Dahlia'.
