Citrus General Discussion / Re: High potash or low biuret urea ahead of flowering?
« on: December 19, 2024, 10:22:01 AM »I have used low biuret urea to greatly increase spring flowering, it works great. According to the Citrus Production Manual, published by the University of California either Low Biuret Urea (46-0-0) or Potassium Phosphite (0-28-26) can be used. The spray to increase bloom should be sprayed between December 15 and to February 15. For warm greenhouse production the earlier spray of December 15 provides a much better bloom. I can find no where in the University's production manual that it states that nitrogen inhibits flowering.Thanks Millet. But I am a bit confused by the recommended sprays you mentioned. Either the high N sans any other macro nutrient OR high P-K sans N? Its a bit confusing as they are direct opposites in terms of the N-P-K content. Why not just combine them for maximum effect, as one might conclude from the Citrus Production Manual (per the part I italicized in quoting you)?

Citrus General Discussion / High potash or low biuret urea ahead of flowering?
« on: December 12, 2024, 05:46:44 PM »
For a while there it was recommended to spray citrus with a low biuret urea about 6-8 weeks ahead of flowering. But I just read that the nitrogen actually inhibits flowering and a high potash fertilizer is recommended. Has something changed?
I have been away for a while, as all my trees succumbed to winter storms Urri and Elliot and I was slow to replant..

Is the midline of the fruit curved or straight? If it’s curved when you cut the lemon down the poles is HLB.

I wonder if Texas has a similar program.

Looks like rust mites. Lemons are very susceptible to those little guys. Also, you tree looks under nourished.

I’m in the quarantine zone and had to take down a couple for HLB trees in ‘21 and it doesn’t show anything. Must be good in California only?

Um, I am in Houston as well and had a large grapefruit and blood orange diagnosed with HLB by Texas A&M a couple of years ago. Harris County is in the quarantine zone for greening and while the trees you buy may not have the disease the Asian psyllid is here and can infect your tree as it did mine.

« on: January 02, 2023, 11:31:07 AM »
If you take one of the fruit and cut it down the middle from pole to pole (not through the “equator”) if the center is curved it is definitely Greening.

If they have any fruit the center column (the columella i think) will be curved.

Citrus General Discussion / Re: Its Now Time To Foliar Feed For Best Crop Of Fruit
« on: July 22, 2022, 03:33:22 PM »
My citrus are only in the ground 1-2 years (all my 14 or so citrus were extirpated by Winter Storm Uri Feb '21) and are currently not holding fruit. Does this foliar spray benefit a tree without fruit? BTW, I do have my trees on a regular fertilizer regimen, fertilizing them 3-4 times a year.
Thanks

« on: June 20, 2022, 04:22:23 PM »
I do not see any fruit on the tree, but if it has some, cut it down the middle along its axis (not along the "equator"). If the central column in the fruit is curved, rather than straight, that is a tell-tale sign of HLB.

Citrus General Discussion / Re: when to pick Chandler pummelo?
« on: June 06, 2022, 11:34:12 AM »
Fortunately, my Chandler died due to winter storm Uri. My Bloomsweet and Ruby Red grapefruits nearby all developed wonderful flavor, but the Chandler always tasted flat to bad even when picked all yellow. And when I let it hang until Feb or Match it got dry and really bad. Never could figure when the best time to harvest the fruit was because early or late it was less than satisfactory.
Clearly I was doing something wrong.

« on: January 17, 2022, 03:08:24 PM »Total agree with Vlad. Buy a grafted tree from nursery cost around $30, and 6 buds cost $30. Totally not worth it.Living in a citrus quarantine zone I can't always find the varieties I am looking for at local nurseries and mail order is not permissible.

« on: December 14, 2021, 02:03:35 PM »
I am under the understanding that frost owari is a nod to the name of the individual who developed it. It has no reference to its cold hardiness. So, Frost owari has the same hardiness as other satsuma's. If I am incorrect, someone please correct me.

Yep. Wasps are effective caterpillar hunters on my citrus. I wish there was something that targeted CLM in such an efficient manner.

Leaf minor eggs would be so small you need a microscope to see them.

Giant Swallowtail eggs. While the larvae in great quantity 'might' be a problem, a couple will eat some leaves but not really hurt the tree unless the tree is small. How big is this poncirus?

Bears! I doubt a few poncirus branches will do much to deter bears. I would think squirrels would also find a way around them, those nefarious vermin.
