Mock orange in beautiful full flower! Many yellow leaves -- must be Gold Leaf Mock Orange!

I can't remember if it flowered last year, but my post on May 22nd 2001 commented on how horrible it was looking.

This year the flowers are gorgeous and smell amazing, lots of bees and flies etc. visiting the flowers.  However, most of the leaves are very yellow, like last year.

Oh, wait!  Google says there's something called a "gold-leaf mock orange", and the photos look similar to mine!  This must be what it is!  Yay!

This post talks a bit about pruning it, removing the oldest stems, etc:  https://awaytogarden.com/great-shrub-gold-leaf-mock-orange/

Mock orange looking horrible, applied condo 'soil' and kelp meal (and trimmed dead branches)

I think it was last year (if not earlier) that I noticed the mock orange (I think that's what it is) is looking horrible.  Lots of branches with no leaves, and most of the leaves are yellowing.  A few branches have very nice green leaves but most are in rough shape.

Last year I didn't do anything about it.  This year I decided to at least give it it a try.  So I sprinkled kelp meal plus three buckets of the condo soil (maybe triple mix?) over top, and cleared away dead branches as well as the lemon balm growing in front.

We'll see how it does.
