Hello,

I just watched the video of Citrina, an ornamental dwarf citrus tree company in Portugal, it is very very impressive.

Please watch the video here;
https://www.citrina-plants.com/en/citrina/

This is what I dream to do as business in a longer period, very satisfying.

The main process should be;

1. Using a dwarf rootstock such as flying dragon and making a very strong root structure. ( On 00:44 rootstock leaves are visible and easy to identify I guess, I couldn't identify though)
2. It seems that at some point where the rootstock is 25-30cm long, and small in diameter they cut it and cleft graft the scion (00:44)
3. The rest is a well planned nutrition I guess.

Hello.

I thought Gold Nugget mandarin was still patented as it is said on;
https://www.fourwindsgrowers.com/products/copy-of-gold-nugget-mandarin-patented

But on Google patents, Tango page;
https://patents.google.com/patent/US20070056064

it says;

Recently released mid to late season cultivars that are very low-seeded include ‘Gold Nugget’ (unpatented), ‘TDE2’ mandarin hybrid (Shasta Gold®) having U.S. Plant Pat. No. 15,461, ‘TDE3’ mandarin hybrid (Tahoe Gold®) having U.S. Plant Pat. No. 15,703, and ‘TDE4’ mandarin hybrid (Yosemite Gold®), having U.S. Publication No. 2003/0237120. ‘

And the patent search there doesn't list any patent for Gold Nugget, despite listed varieties such as; tango, TD3, Daisy

Is there a better source than Google patents to check patents?

Best.

Hi.

At the beginning of spring 2017, when season starts we noticed a big problem on one of Meyer orchards. Leaves got yellow gradually quickly. We supported with trace elements, iron and applied %35 Metalaxyl and % 80 Fosetyl-Al in order.
Trees recovered and continue well in the summer. Then in September, the symptoms seen again and the tress died one by one, all of the orchard.

We got the soil and dead trees tested and nothing significant had been found, only some pathogens which are not the reason but the result of dead roots.

Unfortunately, we have 8000 more Meyer lemon trees on C35 rootstock in another orchard. We got afraid a lot at first but they were fine until last month. This month they showed the same symptoms and I am afraid the result will be same. This time we support with zinc and manganese because C35 is susceptible to them but I have no hope.

When you pull out a dead tree, you can see there is a very limited root development. It is obvious that the top part was not successful to support roots.
And rootstock-bud union connection shows a swelling on bud part.
At final conclusion we think it is a rootstock - scion incompatibility.

I would like to hear your experiences with C35 and meyer or other lemons.

Have a nice day.

Hello.

It is Mehmet Saygin, an old member from the CG Forum
I was not an information provider at that time, I was like a citrus tree sucker. I am spending more time at the orchard for the last 2 years and still learning but meanwhile maybe I can share what we do at the orchard, like a diary, not daily but from time to time. Following the work on a commercial Turkish citrus orchard maybe interesting to some of you.

This week the Interdonato Lemon is harvested. Russian market is slow this year so farmers are having a difficult time selling lemons. Actually interdonato lemons should be harvested 2 weeks ago, fruits has started to lose quality but on the other side they are full of water and heavier so this helps the total yield.

I am attaching 2 photos, you will see discard fruit on the ground, hurt by the Citrus Rust Mite (phyllocoptruta oleivora)
Quality fruit is harvested to be exported to North Europe and Russia and the buyer left the discard fruit on the ground. Then a local buyer selected what he can sell on local market and these are the left over. We will collect and dispose of them.

The tree seems tired. We will apply sulfur first to control the rust mite and then support the tree for winter.
