I want to grow some lavender from cuttings.  I have been looking it up and have found good information but some contradicts a bit and I want to know what to do here in Lakewood, Colorado.  One item is when to  take the cuttings.  Some say early spring others say in the late summer or fall then overwinter them.  Early spring is so unpredictable here, well all the seasons are these days, so I don't know which is best.  Some say to use growth hormone, other's say you don't really need it.  I can propagate in soil or water but they say that it is harder to plant the ones done in water.  How so?  I prefer using water because of how my living space is.  Finally some say that lavender does poorly or not at all in clay soil and you should amend it with sand.  I have also heard that sand is a bad idea for everything.  If sand is a good thing how deep would it need to go.  My one lavender plant was planted directly into the ground and it is fine.  Thank you.
