Yes, you can buy urea. Have you been told about the consequences? Everything that you did not write, I finished thinking for you, since I represent WHAT YOU NEED. I believe you should buy the least problematic fertilizer for the grower, and for the tree, in the long run. And, the effectiveness on the fruits is secondary. If you buy urea. - Urea causes strong branch growth. Do you want the tree even taller than it is now? - It is not known how Urea will act on boron. - Biuret 1% is a lot for citrus fruits. I don't know what the result will be. Biuret will probably hit the flowers hard, but at the same time it will hit the leaves ... You need to accurately calculate the dose. I don’t want to take it upon myself as to what dose is needed.

It was a good balance of flesh and juice. The peal was very hard to remove but at 7 inches I had a 5 inch ball of seedy flesh. All the seeds were in the sections center crease. I ate mine out of hand. I considered the tree not worth growing and I let both of them die over the winter, They were very aggressive growers and put out 8 -10 foot shoots that I could not protect. 30 gallon transplant into ground 12 foot tree freezing to death 8 foot diameter at 6 feet tall It is big Steve

I've grown them both. (Funny how I started this topic.) They taste different. Orange Jazz has one of the more unique flavors among orange tomatoes, in my experience, and it's the same color of orange as Amana Orange (sans the stripes). Amana Orange is a relative to it, and it shares some of its flavor. Sweet Ozark Orange is definitely more meaty and peach-like than Orange Jazz. Orange Jazz was more prolific for me. Sweet Ozark Orange had bigger fruit. Orange jazz had fibrous deep veins attached to the calyces.

Hi Dennis I have a Dwarf Cara Cara Navel Orange tree and it is growing very nice In a container, also the Cara Cara Oranges are sweet and great for juicing. I cant say much about the sanguigno Blood Orange but I imagine if you get either tree on a dwarf root stock you should be fine container growing them.
