Posting in the Northwest Gardening forum and the OP's screen name including pdx (abbreviation for Portland, OR) should provide a clue to location :-)

Frankly, I was surprised to see anyone in OR planting a buddleia as they have been banned for sale as a invasive noxious weed. However, I did determine that a short list of selected new sterile cultivars can still be purchased and planted. And that invasive label should be an indication that not much will deter the vigorous growth of this shrub in this area. But poor drainage or overly wet soils will.

I would not hesitate to move it now! Relocate to full sun and good drainage. And water only when you have experienced a long dry spell.

Thanks Gardengal. I think you meant move to the permanent location not the pot. I have another buddlea since 15 years, doing well, no signs of invasiveness. I bought this dwarf variet at a local wellknown nursery last october.

Ken, I dug a hole very slightly bigger than the pot it came with, base of the root slightly higher than the surrounding soil. It was not a bare root. I pruned in March when it appeared fine, no yellow leaves then. The yellowing started in April. I must admit I was watering it atleast twice a week since May. The current location is getting more than 6 hours of sun.

Invasive characteristics will rarely show up in a cultivated garden, which is one of the reasons invasive species are so perniciously able to spread. You just won't notice it. Each buddleia flower can produce as many as 40,000 viable seeds and the reason only sterile forms should be planted.

Now that I am thinking about it, I do remember seeing these in roadsides near Seattle.

Re invasiveness of Buddleja. This is what happens if you moor in one place for too long In Buddleja country.

I believe the local nurseries here sell only sterile varieties. I just dug out the plant and found subsoil fairly most although it was not watered or rained for a week, not sure why soil could be moist. Anyways, it is now at the new location, that in a slope also and subsoil is bone dry. Hoping it will make it. No mulch or compost was added.
