Compost enriches the soil and if put on thick enough can be a temporary weed mat. It is not the best solution for reducing water evaporation. It is recommended that a mulch, such as bark or leaf mulch is put on the top.
This product is mulched up wood and leaves. Its benefits are that it is a very effective weed mat but it decomposes quickly enriching the soil while generating heat. It is an excellent way of reducing evaporation, creating a warm, wet blanket over your soil. During decomposition it can take nitrogen out of the soil, so it is advisable to add a general fertilizer, such as blood and bone with it. It is wise to seek advice from our staff about how close to push it around certain plants.
Pea straw is the royalty among mulches. It is rich in nitrogen, breaks down beautifully and is an effective weed mat, as well as reducing evaporation. Regrettably it can take off in Wellington winds so it is best used in a sheltered spot. An added bonus is that peas often grow out of it.
Bark is the longest term organic water retainer of the mulches. It can make the soil acid and will take nitrogen from the soil as it slowly decomposes, this can be addressed with additions of lime and a general fertiliser. It creates a spongy attractive layer that can be walked on without causing the damage to soil that would otherwise occur from heavy feet
These make an excellent mulch for those areas where you want to plant a garden that requires limited maintenance. This, plus a weed mat on top, is an excellent way of retaining moisture and reducing maintenance required by weeding. If this mulch is used under trees leaves will fall down and eventually weeds will grow on the surface layer.
We can deliver the mulch of your choice by truck, or it can be collected in the free courtesy trailer.
