Is there a good source to buy a couple to rootstock for stone fruit trees?

My tango has a flush of flowering at this time of the year.  The amount of bloom is almost as much as in the spring?  Has anyone seen this before?  For background information, this tango had a big flushed of blooms in the spring but set very few fruits.

It's an multi-grafted tree.  I think this part is the ponkan.

with updated picture it looks like a kumquat, nagami type or hybrid?

When I have seen this type of cupping it seemed to be caused by the tree becoming too dry at some point and beginning to shrivel.   Even after proper watering the curled leaves never returned to normal, but new leaves grew fine.

I hope it's not either.  Glory to Jesus Christ..thank you.

I hope it is not HLB by the way. I don't want to be a pessimist, but that disease has just been burned into my brain from seeing it everyday. It has been a heart breaking disease to watch here in Central Florida. Kindof like being forced to watch your home burn to the ground without being able to do anything to prevent it. I have several dear friends in the industry among them are one in his 80s and another in his 90s. They remember Florida before AC and Disney. Few people have worked harder or longer to earn what they have and it breaks my heart to see them working to the bone when someone in the corporate world would have been retired for 20 or 30 years by this point. Neither of them would have stayed at it if they thought there was any possibility that they were harming others by all the things they were trying to find a solution. Neither they nor their groves will be around much longer--what can I say. The Lord gives and takes away. Blessed be the name of the Lord.

What are the possible cause for leaves cupping like a taco?  Updated with the correct picture.

The two sumo are 2.5 years and the multi-grafted one is 4 years old.  I topped the multigrafted last year and graft a few different varieties onto it.  I fertilize about every 2 months. 

No not citrus greening.  Many of the leaves are just showing that they are old.  A citrus leaf has a life span of 18 months.  How often do you fertilize your tree, and how old is the tree/

Location is san diego out of the quarantine area.  However, I'm seeing signs on my trees that I think could be citrus greening (huang long bin).  These trees were healthy as recent as 2 months ago with full of little fruits.  I fed them with micronutrients in late February so I think it is not a micronutrients deficiency.  But I left town for 9 days 6 weeks ago and when I came back it deteriorated.  Below are some pictures.  I have contacted CDFA and they will have someone calli me next week to check.  I'm dreading this.  Two of the trees in the photos are sumo and one is a multigrafted.  Do they look like citrus greening?

How would you rate the taste of Don Gilogly?

Last year we planted out over 60 seeds from our Don Gillogly tree in Fallbrook to use as rootstock and they are doing great.  Surprisingly, on most of the trees the older leaves from last year still look great without any tip burn and the seedlings are branching out nicely and have a good shape.  Our mother tree at home is over 15 years old and produces reliably even with our clay soil and cooler weather.  It also thrives with minimum watering, I don't water it at all from late fall to early spring and only once every couple weeks during summer.  I'm sure it would need more water in a warmer climate, but our highs are still only in the upper 60s, forecast shows high of 73 this next week. 

In March, we purchased an old avocado orchard with about 2000 Hass and Reed trees.  The water on the property has been turned off for about a year, but we have been harvesting some Hass.  Some were better than any avocado we have ever purchased.  I was surprised at how good some of them were even on neglected trees.  We also tried a couple Reed even though we knew they weren't ready yet and fruit was still okay, so looking forward to trying them in a few months.

Now that we have these mature trees, we plan on letting all the Don Gillogly seeds grow into trees to see what we get.  Looking forward to experimenting with seedlings and grafting new varieties onto some of these old trees.

Satya, my BC did the exact same thing.  It was the first to leaf out and was looking quite good and afterwards wilted.  It looks dead from what I can tell.  The others that leafed out are doing well.

Same here...It had the best roots also. Maybe it has to do with something else as my other trees are looking fine (at least for now).

My BC did the same thing. It was the first to leaf out, then slowly wilted away. I'm waiting if it actually comes back. Another BC that also leafed out is not completely dead but it's struggling. Anyone can think of what can be the problem?

The same thing happened to my two BC.  Leaf out first then shriveled and died.  May be due to RKN infected roots.  I noticed when I received the trees, the BC roots were the least developed.

Can you root from these cuttings?

Brad..

I remember you have a nimlioh in your yard.  Has it fruited for you yet?  How does it taste?

This is my biqi (the fastest growing one I have).  I didn't pay attention to the root when I received my batch of trees.  What are the symptoms to the tree when they have RKN?

As a best practice, I prophylactically treated my trees with this product



When we received our trees in April 2021, I noticed what might have been RKN on the bare root trees so I looked under a microscope and dissected some of the galls and didn’t see any live nematodes.

Shortly after the shipment, I messed up and may have accidentally inoculated my soil with RKN thinking it was Frankia, still not sure but anyway, I used this product and waited about a month and then I used these beneficial nematodes

As you can see by the pictures of my Yangmei roots, there is no sign of RKN.

It would be wise for all current and future Yangmei group buys to prophylactically treat their trees.

RKN thrives under certain conditions and some parts of Florida and California may have conditions where RKN can thrive. Under less than ideal conditions, RKN will not flourish and will not cause much of an issue but it’s always better to be safe than sorry.
