Unfortunaly since Peat is not normally used in seed and potting composts the quality has dropped, I never understood why people used peat directly onto gardens that was a waste, but for container plants it was the best, though I use a 70/30 mix of good garden soil to my own garden compost for ground containers, also for planting seed runner beans in pots to plant out in the garden whne the fear of frost is over, not happy with what I see as peat alternatives.
Verdun, what does that Wyvale compost smell like, I have tried others that plainly stink. Also, does it contain some peat?
Have you tried Jacks Magic
Great for seeds and cuttings
yes b and q compost is crap we use grow well from codnor horticultral
Verve gets bought when they are practically giving it away and is used only for winter dressing stuff like Lupins to keep the frost off. About all its good for.
As far as seeds go, generic MPC/Coir in equal measures with a few handfuls of grit. Not brilliant, but gets the job done. Just don't get enriched MPC.
B+M (not B+Q) sell good compost this year. I mix it with John Innes seed compost for seeds and John Innes potting compost for plants. It works fine.
Problem is a lot of composts are packaged too soon and really need at least 2 years to breakdown into a fine peat like texture. The woody bits you get in bad compost end up lowering the nitrogen content as bacteria use this nitrogen to digest the wood chips.
Ive looked in the garden centre and so far Miracle Grow seems the best
Another one for Verve being awful, bits of glass last year not good trying to encourage Grandkids to help out. Been using Durstons for a little while and seems ok. Might try Wyevale.
There is two sorts of levingtons. The stuff packaged for gardeners contains recycled rubbish and is made by one firm, and is sold in garden centres.
The other stuff is packaged for nurseries, comes by the pallet load, and is fine peat based. If you can get it, its called Levington Pro . I use the levington pro M3 for potting on and tomatoes in buckets. I add some perlite to it to weaken it for seeds, although they do make a seed compost.
