    Hi there.

    I am trying to germinate Citrus seeds of the rootstock P.Trioliata (purchased from a Citrus Organisation locally). I am planning on budding my desired varieties on to these seedlings at a later time. This question is just about germination.

    Now that I have my cold frame (see "Want to Build propagator"), I am about to start on germinating seeds. I am about 7 weeks away from last frost in my area (its Winter down here in Australia) and I think that gives me enough time to get the seeds to a size where they can be potted up and out of the cold frame at that time for spring growth. (2 weeks to germinate, 3 weeks to first true leaf)

    I want to make my own if its cheaper, or should I just buy a seed raising mix from the nursery? I cannot find anything detailed on google. What mix do I put in the seed trays / flats?

    So far I have found that a general mix is

    2 parts Peat (or substitute),
    2 parts sand
    1 part loam,
    with minor fertiliser and minerals.

    But is this good for citrus?
    Can I substitute Coir Peat (coconut?) for real Peat?

    Any ideas would be great. Any Citrus growers who might have handy advice please add whatever tips you can. I am doing this for about 1000 seeds (Should get about 20 trees after the learning process takes its toll :) ), so I want to get it as right as I can for consistant seedling production.

    Thanks
    Raphael in Australia.

    You Might Goggle "ifas Citrus " That Is The Univ. Of Florida Institute For Agriculture.

    If You Have That Many Seeds, Why Dont You Try Several Dif. Mediums?

    We Have Lovely Citrus Trees Growing Wild. I Would Like To Grow Some Of The White Grapefruit We Have From Seed.

    Hope You Give Us An Update From Time To Time.

    You might want to check the Texas citrus research station in Weslaco Texas they do alot of research and breeding of new varities there.
