What is the difference between grit and horticultural grit?
Horticultural grit has sharp edges, where as gravel has soft edges. Gravel will work ok but can also cause blockages in a pot. Grit with sharp edges make much better drainage. Sharp sand as used in cement also works well as it grittier. Horticultural grit is a great alternative to horticultural sand. It’s made from crushed rock like granite or limestone and is usually lime-free, making it safe for plants. The coarse texture helps with drainage and prevents soil compaction.Don’t use building sand as it contains too much lime. Ask for washed or lime-free, sharp (gritty), horticultural sand. Crushed gravel is cheapest, but pea shingle and decorative stone chippings are also suitable.One of the primary uses of horticultural grit is to improve soil drainage. Poor drainage can lead to waterlogged soil and root rot, which are detrimental to plant health. By incorporating our grit into your potting mix or garden beds, you can prevent these issues and promote healthier root systems.Yes, sharp sand can be used as an alternative to horticultural grit, especially in scenarios where improving soil drainage and aeration is needed. Sharp sand, being coarse and well-draining, is particularly useful for garden beds and containers that house plants requiring excellent drainage.
Which is better, perlite or horticultural grit?
Also I find perlite better for cacti. Vermiculite stores moisture, perlite aerates the soil. Grit keeps the soil lighter and less compact I guess, never used it much exept some times in my pelargonium pots. Vermiculite is better for water retention, that also means in that moisture it retains key nutrients for your plants and cuttings to soak up. Perlite works better to help drainage, this means its also better for loosening heavy, compacted soil.Coarse sand (not builders’ sand) can be used instead of grit in small pots but can compact over time. Bark chips can improve drainage and aeration in mixes for orchids and some epiphytes. Vermiculite holds more moisture than perlite and is better suited for moisture-loving plants.
