    Default First time growing, growing: Carrots, Onions & Potatoes.


    So, a few weeks ago I decided I was going to start my long venture into self-sustainable living. To kick start this off I've decided to grow Carrots, Onions & Potatoes.

    My questions are mainly related towards Carrots but if you feel you have any hints and tips based on the information I'm about to give you towards onions and potatoes, everything will be noted.

    So, Basically, I don't have a garden. I will be soon moving which hopefully will have some form of patch of land I can grow properly from, but for now I'm growing from pots. After a few hours of searching the internet for what is best to grow in, I went to B&Q and bought some sharp sand, multi-purpose compost, vitax calcified seaweed, Liquid seaweed and Vitax potato fertilizer. If I'm growing carrots, I've heard carrots grow best in a sandy/soil mixture, whilst not over doing it on the nutrients. i plan on mixing 1:3 sand:soil ratio, mixing with calcified seaweed a few weeks before planting my seeds. my couple of questions are...

    1)What ratio should my compost to sand be? Is this right?
    2)How much calcified seaweed should i use?
    3)What else can I buy to help growing?
    4)Am I just completely wrong with what I'm doing?

    Basically what I'm asking is for a first timers guide to growing carrots in Pots. I know it's not just as simple as saying this is what you need to do, so maybe a couple of starting points for me?

    If I'm wasting time with 'noob', information grabbing, I apologies, i feel like I've exhausted my resources and aren't getting the information I'm looking for. I'f you have a link to previous post that answers these, that would be great also.

    Thanks for reading.

    Hi dantribe,
    I just grow my carrots in a trough, using a good multi purpose compost. I don't thin them out, just leave to grow, then when they get to a reasonable size pull some to use as baby carrots, as if you're thinning them, and leave rest to grow on.

    Dan welcome to the mad house. It may take a couple of days but you will get answers..........lots of them. Remember if you ask two gardeners the same question you will get at least 3 answers.

    First you can help us by putting you rough location in your profile it will make the advice given more specific to you.

    I friend of mine grows carrots in containers, he has no soil so use approximately 3 parts MPC (multipurpose compost) to 1 part sand. Remember what ever you put in the soil you will need to feed at some stage. He chucks in a couple of tablespoons of gromore a basic 7-7-7- fertilizer but calcified seaweed would IMO do just as well. For containers he use MBFB (Morrison's black flower buckets) cheap as chips at 98p for 8 and you just need to put drainage holes in the bottom.

    One point we found out when he first started was to scatter the seed very thinly either that or thin the carrots out as they grow. At his first attempt he let them all grow to maturity and it was a heck of a job to lever them out of the pot.

    Onions, I grow in containers, you need something about 8 inches deep again I use MPC with a good dose of pelleted onion fertiliser mixed in, not an accurate measurement but I throw in a good handful to 30ltrs of compost. Again you will have to give additional feed as they grow.

    Potatoes are relatively easy if you follow a few simple rules. It depends on what you want to grow earlies can be grown 1 seed to a MBFB or three or four seeds in a larger container. Again you will have to supplementary feed and keep well watered as the tubers start to develop.

    If you are thinking of moving this year I would keep my containers down to a manageable size to allow me to take them and my produce with me.

    Hello Dan and Welcome

    I grow my carrots in a wooden box made out of old pallets but as it is starting to fall apart I will be trying Potty's flower bucket idea.

    In the past I have added sand as a third - 2 MPC and 1 Sand. It works just as well for parsnips.

    Potatoes go into buckets - 1 per bucket.

    Growmore, chicken pellets or blood fish and bone (BFB) can all be used as a feed.

    Try not to get your self stressed over your new project.

    Hello and welcome
    Although we have a garden, we grow mainly in pots and containers.
    Potatoes, carrots, onions and tomatoes grow extremely well
    Just remember that they will need lots of watering as well as feeding
    Good luck
