Is Mushroom Compost Good for Grass and Lawns?

If you’re looking to grow new grass seeds or lay new lawn turf, you should consider adding a layer of mushroom compost to enhance its growth. Mushroom compost is often said to be a good product to use within flowers and vegetable beds, but not many gardeners know if it can help their garden lawn.

In this gardener’s guide, we outline whether mushroom compost is beneficial to use when growing new grass seeds or laying new turf.


Can I use mushroom compost to grow grass seeds?

If you’re looking for a quick answer, then yes, it’s good to mix grass seed with mushroom compost for small areas of your garden and other applications. Whilst you can mix the two, it isn’t the preferred method for all situations.

Young grass seeds require a range of factors to ensure they grow in a healthy manner and water is high up on that list. One of mushroom compost’s best qualities is its moisture retention capabilities, which makes it a highly sought-after fertiliser to use in the garden.


Should I put mushroom compost down before or after seeding?

Mixing grass seed with mushroom compost in addition to turf and lawn topsoil is the best way to spot-apply seed to small patches and thinning areas of your grass lawn, however, if you’re wanting to grow turf in larger areas, the optimal method is to simply put a small layer of topsoil and mushroom compost (2-3cm) down first, then use a grass-spreader to evenly apply your grass seed.

Grass seeds are particularly small, and they are extremely sensitive while in the germination stage, which means if you put mushroom compost on top you could end up suffocating the grass seedlings before they have a chance to grow.


Benefits of mixing grass seed with mushroom compost

Mixing grass seed with mushroom compost has a vast range of advantages not only for your garden but for yourself also!

  • Adds nutrient-rich compost to your garden
  • Improves moisture retention
  • Saves valuable time for gardeners
  • Can break down clay
  • Discourages weeds from growing
  • Ready-to-go mixture for quick fixes

Excellent product at a sensible price from a local supplier. Staff are friendly and willing to help: I asked if just one bag of topsoil could be delivered quickly and it arrived next day! Great service.

Smooth execution of the transaction and delivery. Very helpful phone call and conversation. Ordered three bags of Border Blend topsoil. Paid by Paypal. They delivered, on the specified date, carefully, exactly where I wanted the bags placed. All in all, a very pleasing purchase. The topsoil was excellent and had been very carefully prepared. No lumps. Would definitely recommend and I will use again. Everyone I spoke to was nice and helpful.

Ordered topsoil on Tuesday came by Friday at the exact time quoted. Was WAY cheaper than anywhere else (by about £15 per bag) and was dropped off via a crane on back of the lorry, not by pallet which most of the other places use. Soil was fine and dry. Brilliant !
