Pea Straw





Pea Straw

  • A natural mulch
  • Improves soil structure
  • Improves drainage
  • Suppresses weeds
  • Adds nitrogen to soil


Pea straw can be used as both a mulch and a soil conditioner. It is high in nitrogen and breaks down quickly to release nutrients for plants as well as adding organic material to improve soil structure. Pea straw is ideal for use as a mulching layer around heavy feeding fruit and vegetable plants where it can help to suppress weeds from taking hold and competing for nutrients and moisture in the soil.  As pea straw breaks down it releases nutrients that boost soil microbiology (all the tiny organisms that help to make available essential nutrients that plants need to grow well).

Used as a mulch predominantly during the warmer months from Spring through to Autumn. As a soil improver and conditioner it is used year round.

Pea straw can be applied as a layer – about half a finger deep – around seedlings and mature plants. Chopped pea straw – often sold in bags mixed with lucerne – is easy to place in a uniform layer around small seedlings without them being covered up and deprived of sunlight.  Used like this it can help preserve moisture levels by preventing soil from drying out. If you are applying a mulch of pea straw on a windy day it is worth damping the pea straw with a spray of water from a hose or watering can once you have laid it on the soil to stop it blowing away

Pea straw can be dug into garden soil to help improve its structure and moisture retention. With sticky clay soil - where particles are very small – pea straw helps to open up spaces between the compressed particles so that water and air can more easily move through the soil. On sandy soils where water passes through very quickly and soil can become dry too fast, pea straw helps to hold onto moisture so that it is available to plants for longer. Adding pea straw to garden soil also increases the nutrient content of the soil as it starts to break down.
