Sowing: Seed Compost Vs Multi-Purpose Compost
Just an idle chat thread . I bought 2 big bags of seed compost because it was cheaper that way and now I'm kind of regretting it as I can't see myself using them all up this year. Presumably they don't keep well either.
I know some of you use multi-purpose compost for seed sowing and I myself couldn't see much difference between the two except that the seed compost had bits of sand thrown in (I mean how difficult is that!). I think in future, I could save myself the bother of buying/storing/using 2 types of compost when one (that's multi-purpose compost) can cover all my compost needs. Am I missing something here? Besides seed compost cost more.

I always use multy purpose compost for sowing. They sometimes has big lumps which you have to break it up but anything than that is ok. I also mix it with a bit of sand to help the drainage. The compost will keep well for next year Veg.

I usually use seed compost for early sowings & expensive or tiny seeds; I find multi-purpose wastes too much when sieving out the lumps, and then faffing around mixing sand into it... If you don't put sand in, the seed casings are more likely to stick on!
Ami, if you have seed compost leftover, it could be good for growing herbs or something that likes well drained soil?

I am experimenting with a mix of potting compost and coco coir, 60% compost and 40% coco coir, in my latest seed sowings, so far they appear to be growing very well.

I always use multi-purpose for my seed sowing, I always sieve it to get all the large bits out and put some air into the mix. I find that not all mp composts are the same and some are not particularly good for sieving as SarzWix said you can loose a lot with some makes. Dont know how the moderators feel about mentioning a particular brand but he one I use would be a collection of diamonds, rubies ans emeralds.

i use multi purpose as the base
1 scoop perlite
1 scoop sharp sand
1 scoop horticultural grit
9 scoops multi-purpose compost
this never lets me down and i feel it allows seeds a more favourable growing medium less dense and better moisture controlthis will be a battle from the heart

I think a lot depends on the brand of MP. Some of them are very coarse (particularly, unfortunately, some of those peat-free options) and even small seeds get swamped. I did a lot of sieving last year!
This year, as an experiment, I am using seed compost for seeds, and MP as they grow larger. We'll see it that works better.....
