A couple of days ago on August 30th I re-planted my Colorado blue spruce dwarf weeping variety called 'the blues' into the same 20 x 20 container, but I used a 3 part mix of 1 part potting soil (sphagnum peat moss, perlite, starter charge, dolomitic limestone, calcitic limestone, wetting agent), 1 part lava rock and 1 part pine bark fines to make the soil fast draining. In August we had 9.14 inches of rain which was above average and the potting soil in the container stayed very moist which caused the tips of the blue spruce to turn yellow from too much water since they don't like wet feet. Thankfully the last few days it has been hot, windy, and mostly dry and the forecast calls for more dry weather. It has only been in it's new soil for a couple of days, but it already looks better and hopefully it thrives. I still have it on the east side of the house so it only gets morning sun, but once it gets cooler I will move it to the south side of the house so it can get full sun. Does this sound like a good soil mix for a dwarf blue spuce in a container? (I originally received and planted the spruce a month ago using just potting mix).
