Yes, we are Sunset 3B here.... The sunshine on most days and temps in summer is the reason so much agriculture grows successfully here. Of course, they irrigate. I am surprised Wenatchee is the same zone as us, but I guess it doesn't take into account the amount of snowfall they get (They are probably the -15f extreme.. we are more like -5f.) RE: the suitability of the trees I listed, The Thornless Honeylocust seems to thrive here, it does well in alkaline soil and is drought tolerant. As a prairie tree, it thrives in full sun. I have noticed many honeylocusts in yards that do not irrigate, growing just fine... The list of negatives of the tree is pretty short, and it seems very adaptable to our conditions. Linden -- RE: irrigating, I don't know. We will have some lawn on the property, so a tree/trees in that area would get more water. Linden tolerates alkaline soil and has small leaves... Thus, it seemed to be an *option.* ash -- I still have to go to our local extension office.. I will ask them about borers here. Ash also tolerates alkaline soil and was another option for my lawn area. If the borers are that bad here, I won't consider it.

Attached a picture of leaves close up for nurseryman33. toronado3800-never even thought of the different soil type and digging times. Yes, they are right heights. The University of Kentucky suggested I have "Anthracnose Disease". Too much water. But, this has not effected the Red Sunset Maples..... THANK YOU for responding. My searches are not finding the problem/solution....

We have two of these wonderful Maples. Ours took awhile to adjust and develop. We planted both in 2002 when they were about 8 feet tall. They grew very slowly while enduring both drought and deluge. The leaves were unspectacular for a couple of Autumns. This year we noticed a huge amount of growth. Over the past few weeks the leaves have turned a fiery red which can be seen 2 blocks away. Sounds like yours is just fine, just give it some time.

Identification suspect - I have to wonder about one USDA Zone difference causing a nearly two month differential in fall color timing. Unless, perhaps, it is drought induced. In which case somebody needs to be watering them, if they look as bad as the red maples that are coloring already up here. I am convinced that the new seedling represents a new and distinct variety by virtue of the following unique characteristics which distinguish it from all other varieties of which I am aware: 1) A moderate rate of growth; 2) Shapely oval head which is formed and maintained without costly pruning or staking; 3) A habit of retaining the foliage from 3 to 4 weeks after all other red maples have defoliated, and 4) A distinctive and attractive Bright Crimson Red general color tonality of the foliage which is invariably attained in the fall season regardless of soil conditions or exposure UNITED STATES PATENT OFFICE - Plant Patent 2,116 http://pdfpiw.uspto.gov/.piw?docid=PP002116&SectionNum=1&IDKey=442E89C058CB&HomeUrl=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1%2526Sect2=HITOFF%2526d=PALL%2526p=1%2526u=%25252Fnetahtml%25252FPTO%25252Fsrchnum.htm%2526r=1%2526f=G%2526l=50%2526s1=PP02116.PN.%2526OS=PN/PP02116%2526RS=PN/PP02116 Horticultural techniques for successful plant establishment https://s3.wp.wsu.edu/uploads/sites/403/2015/03/Planting-fact-sheet.pdf
