Having trouble getting my Lagochilus inebrians to grow. Possibly it's not just the air moisture content. One thing I'm considering is the substrate composition. In the past I've used a balanced mix based on IVS ( In Vitro Soil )- appox 33% large perlite, 33% large vermiculite and 33% good quality peat moss + 1g/L lime. It's been good for most things But maybe it's too balanced. The Wiki entry for Lagochilus states: http://en.wikipedia.org/wiki/Lagochilus_inebrians Intoxicating mint is widely distributed in the Samarkand and Bukhara provinces of Uzbekistan. It is also found in some areas of Turkmenistan and Tajikistan. It grows on the piedmont plains and low foothills, dried up streams and rubbly slopes, on gravelly slopes, on scree and gravel and in dry grassy-sagebrush and sagebrush-grassland steppesNow I understand that some of those terms are soil science terms, ie piedmont plains and somewhere in my searches the word 'sierozem' turned up as a possible suitable base Tried to do some data crunching to see if any of those terms could help me put together a propagation mix which would mimic their natural environment but all it did was put me in a flat headspin with all the options Any soils scientists out there who can hazard a better quality guess as to a potting/ prop mix which would sort out the problems? Even at the basic pH level some readings I find give me the idea the soil needs to be acidic, and others that the gypsum content would make it high alkaline
