Adding nourishment to soil

[Chippychop]

I can get my hands on some manure.. Does it need digging in or just spread in top of plants? Also how rotted /old does it need to be?

It needs to be what they call "well rotted" as otherwise the chemistry of it will burn the plants. You can just spread over the flowerbed (not actually on top of any plants that have emerged) and let the worms take it down into the soil. I put some bought farmyard manure on my beds a fortnight ago and it's already disappearing as the worms get to work.

Oh thanks so much for replying that's a weight off my mind I wasn't looking forward to digging it in! Clever ol' worms!

Yes, look up "no dig gardening". It's the way to go!
