    Hi, can you help please. How do i know when planting seeds which need covering to obscure  the light or which to leave open. These are seeds friends have given me from there gardens.

    If your friends have grown them from seed, you could ask them.  If not there is plenty of info available on the web regarding seed sowing or failing that - look at the back of seed packets in the shops and copy the information down for the seeds that you have.

    I really sympathise with you on this! Seed propogation was for me the hardest part of starting up my last garden.Plants and cuttings are so much easier. Thing is we'd need to see the seeds to help you with this,because there isn't a rule of thumb. There are seed growing workshops available at Wisley if you can get there ?

    This seems like a tricky problem, but when in doubt just cover your seeds with enough fine vermiculite to hide the seed, almost all seeds will potentially germinate well.  With very small seeds this means very little vermiculite indeed which is as it should be as small seeds very often appreciate light.

    See our help and advice profile for more information: http://www.rhs.org.uk/Advice/profiles0301/sowing_seeds.asp

    Did you know that RHS members may send us a list of their seeds and the advice team will indicate which ones need dark and which ones require light to germinate?

    As you might expect, we thoroughly approve of this book that tells you all you need to know for a lifetime of plant propagation:

    There is a great little booklet available which lists virtually any seeds you'll ever have and it lists the kind of compost/medium , optimum temperature, depth of sowing or surface for each kind. It's published for Thompson & Morgan and only cost 99p when I bought it a couple of years ago. It's been very useful to me, particularly for knowing which seeds like sandy compost etc, but it lists pretty much all you need to know. I'd recommend it. 'The Seed Sowing Guide' available direct from T&M but I've also seen it in garden centres.

     To my mind there is no hard and fast rule to this problem.

     

    However their is concensus that very fine seed are generally surface sown.

     

    This is my slant on seed sowing
