You said your lawn needs a lot of work to keep it in reasonable so I guess grass does grow fairly well there....??
I would not add rotting lead mould to your lawn...it is best elsewhere. On your lawn it is likely to do more harm than good.
For me, I would rake, spike and feed. Raking and spiking before spring when ground is not too wet. Feeding in spring with granular lawn feed.
Do you cut your grass hard? Too low a level is not good. I cut my grass twice a week in summer...takes very little time......and the mower blades are set at a reasonably high level.
