Cold Hardy Citrus / Siting Yuzu and Bloomsweet
« on: May 16, 2022, 11:59:09 AM »
I have a Yuzu and a Bloomsweet from Madison Citrus Nursery that are both very small.  I am wondering where to site them on my property.  I'm in a mid-elevation desert in Arizona in zone 9a.  We can get very hot during the day - sometimes, though rarely, 115F - but at night it always cools down (highly unlike Phoenix, which stays hot).  Even in the dead of summer it is still hoodie weather in the mornings for us up here.

I have two places I can plant these, but I was hoping one of them could go in a little mini fruit planting I have.  This area is against a south-southeast facing wall, and gets full (reflected) sun until about noon during the summer.  The wall also has the added bonus of shielding the trunks of these trees from the western afternoon sun after around 1:00 or 2:00.  I have a Golden Dorsett apple, an Ana apple, two Wonderful pomegranates and a Minneola tangelo all growing against that wall, and all are doing wonderful.  The soil is really good, I mulch heavily and apply lots of water.

So - to those with experience with these fruits - can I site them in this spot?  The wall will reflect heat through the morning and early afternoon, but not western heat.  It will be full sun.  I have great soil, I mulch a ton and I provide lots of water.  I would also, likely, use a shade cloth for the first two growing seasons in this spot while the plants get established.

Thoughts?

Thanks!

Citrus General Discussion / Foliar Chlorosis?
« on: May 16, 2022, 11:36:20 AM »
First post.

I am fairly new to raising citrus, have some experience with other trees.  I live in Wickenburg, AZ, in a 9a climate.  The soil in my yard is, for the most part, really good.  This area is in a floodplain that was a cottonwood and mesquite forest for who knows how long, then - about a hundred years ago - was converted to crop farmland.  Afterwards, it was turned into a subdivision, and the house that formerly sat where mine is now had a lawn for 50 years or something.  The soil is, largely, a nice, dark loam that holds moisture well and is generally full of earthworms.

Unfortunately, however, there is one place where my soil isn't great.  This is underneath my lawn, where my grass is.  I had to buy a fair amount of screened fill dirt to build up the lawn area in order to elevate the lawn to a flat plane.  The area is flood irrigated, currently 3x per week (it's a small area, about 35ft x 10ft).

I have two citrus planted in this lawn.  One is a Nagami Kumquat - rootstock unknown but a presumed to be a product of Sunset Nurseries in Yuma - and an Owari Satsuma.  I have noticed that the Kumquat took on a fairly yellow color over the winter, and the new leaves are a bright, neon green.  The Satsuma has remained mostly dark green, but the new growth is - similarly - vibrant.  Photos are attached.

Anyways, I'm thinking this is foliar chlorosis.  I applied some 10-10-10 fertilizer earlier this month, and today added some Kerex as well.  If it is foliar chlorosis, I don't know if it's because I'm water the area too much, or if it's just because the soil is poor.

Can anyone offer some insight?  Does this appear to be foliar chlorosis, or just normal colors of new citrus growth?  Is there anything I should be doing beyond applying Kerex and 10-10-10?  Should I apply a liquid iron fertilizer to the leaves, or cut back on watering?

Let me know, thanks!

Adam
