It's really thriving.
It's good to compare notes because I think our climates are quite similar. I give my landscape Pachypodiums a gallon a week, so it works out to be about the same total volume of water, but I provide 1/10 the fertilizer (=5% of the recommended dose) with decent results... non-stop summer blooming, and a foot a year or more of stem on geayi, which does not bloom yet). Maybe I should water twice as much half as often now those 3 plants are established.
