The undersigned feel there should be a much more open debate on the peat in horticulture issue with both for and against statements up for discussion. It should be noted at the outset we all believe Sphagnum moss peat should not be used for soil improvement.
- It is universally agreed peat should not be used for soil improvement, there are plenty of alternatives for this use, including garden compost, well-rotted manures and leaf-mould.
- Sphagnum Moss Peat from Raised Bogs has been and remains the best constituent for seed, cuttings and potting composts. Peat to case spawned mushroom growing media currently has no alternative.
- Moss peat use in seed and potting composts is currently, by all available measures, an environmentally friendly growing media and in most uses, results in the absorption of CO2, plus the sequestration of carbon in woody growth and the soil.
- Cut-away raised peat bogs can be restored, where water levels are raised and harvested areas re-seeded with the correct species of sphagnum. Newly planted sphagnum grows rapidly, laying down 5 to 7 cms per year, which make peat a sustainable and renewable resource. (e.g. Beadamoss)
- Restoring cut-away bogs and the rapid growth of seeded sphagnum absorbs carbon dioxide in great quantity.
- Most current peat-free composts need much higher rates of base fertilizer (up to four times more) to replace plant foods absorbed by breaking down fibres. They also need more regular watering (at least double), which in turn leads to nitrates being lost in drainage water. Peat has excellent water retention qualities and holds onto base fertilizers to feed plants.
- The growth of some plants is not as good in many of the peat-free composts currently available and this includes all the ericaceous subjects, namely azaleas, camelia, heathers and rhododendrons.
- Air dried peat can be compressed and is light in weight, so uses thinner polythene in wrappers and less fossil fuel to transport.
- Sphagnum moss peat is sterile, clean to handle, pest and pollutant free. Unlike some of the peat free alternatives, where there is a risk of introducing weedkillers and plant diseases.
- Peat free composts are made up to widely differing recipes, so it is very difficult for home gardeners to adapt their watering and feeding practices when the compost mixes are no longer standard. Where they experience poor growth and failures, we risk losing the attraction for people to stay at home gardening and growing some of their own food.
