Gardening with peat-free soil:
\nHow to make the transition a success<\/p><\/h1><\/div><\/div><\/div><\/div><\/div>
For decades, peat was the main component in soil mixes (substrates) in both horticulture and amateur gardening, thanks to its many benefits. The new peat-free and peat-reduced soil mixes aim to replicate these ideal properties using alternative ingredients.<\/p>\n
The quality of the constituents used \u2013 such as wood fibre, green waste compost, bark humus or coconut products \u2013 is especially important, as they affect nutrient supply and the substrate\u2018s pH value and plant compatibility. The combination of different peat substitutes also impacts the appearance and structure of the peat-free mixes, which tend to be lighter in colour and coarser than traditional peat-based substrates.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
WHAT SHOULD I KEEP IN MIND WHEN USING PEAT-FREE SOIL?<\/h3>\n<\/div><\/div><\/div><\/i>WATERING<\/p><\/h3><\/div><\/div><\/div>Ensure your plants receive enough water!<\/strong> Peat-free soil retains less water per watering than peat-based substrates. This is due to
\nthe coarser structure and lower water retention capacity of the alternative ingredients. As a result, you will need to water more thoroughly
\nand, in very hot weather, possibly several times a day. As a general rule, the smaller the container, the more frequently you\u2018ll need to water.<\/p>\n![\"\"](\"https:\/\/www.substrate-ev.org\/wp-content\/uploads\/2024\/03\/Flyer_Tipps_Endverbraucher_ggs-Bewaesserung-400x267.jpg\")
<\/a><\/p>\nTip:<\/strong> In the tried-and-tested \u201efinger test\u201c, push your finger deeper than usual, as the surface of peat-free soil dries out much faster than its
\ndeeper layers. This can give a false impression of the soil\u2018s actual moisture level. For smaller containers, you can also lift the container up
\nand feel its weight to check if it needs watering. A drainage layer of clay or pumice granules helps protect plants \u2013 especially those kept
\noutdoors \u2013 from waterlogged conditions after heavy rain or accidental overwatering.<\/p>\n<\/div><\/div><\/div>![](\"https:\/\/www.substrate-ev.org\/wp-content\/uploads\/2024\/03\/Flyer_Tipps_Endverbraucher_ggs-Bewaesserung.jpg\" "\\"Flyer_Tipps_Endverbraucher_ggs-Bewaesserung\\"")
