I think your best bet is still to get tree trimmings for free from local arborists and just dump a huge layer of that.  After about 6 months it'll decompose into really good soil for trees.  You can always add coffee grounds, manure, compost, and other things on top and as you water them they'll filter down and mix with the tree trimmings.

52
I remember reading that the stuff they give away at Griffith Park is a mix of decomposed green waste, animal manure from the zoo, and wood chips.  (Not sure if it's the same as what you got.)

53
Does anyone in SoCal have recommendations for cherry tomato varieties that grow well as perennials?  I've heard that people living in zone 10b areas of SoCal are able to keep cherry tomato plants growing for many years and they can produce nearly year round.  I've had that luck with many pepper plants but am not sure which tomato varieties would be good for perennial growing.

Even better would be non-cherry tomatoes that produce year round...

Wow, that's awesome.

How do you manage them in the winter?  I had some in containers on my very mild rooftop garden in the East Bay (no temperatures below 39F) and the starapples completely defoliated from the cold wind we'd get.  Cold dry wind seemed to be worse for them than cold rain.  But of course your winter is much warmer and drier than here.

55
Longan should do fine in Alhambra, as should Lychee and many other subtropicals, though given your summer heat you will need to water them a fair bit.

56
Also, if anyone knows where to get US-942 rootstock seeds, that would be another good one to include in the experiment because it apparently had good HLB resistance.

57
I wanted to make a new thread for this idea and see if anyone else would like to try with me.  I was reading this study:

https://fshs.org/proceedings-x/2016-vol-129/FSHS_Vol_129/99-107.pdf

It looks like citron and lime trees have the most resistance to HLB.  So maybe a multi-rootstock tree made up of citron and/or lime seedling rootstocks could have enough resistance to HLB to survive and maybe even thrive.

Here's a source of potential seeds but the smallest order is 1000 seeds of any variety:

http://lyncitrusseed.com/rootstock-seed/

Maybe folks would like to do a group order and try this experiment out?

I'm thinking Volkameriana and Palestine Sweet lime, and maybe one other -- anyone know if any of the seeds listed are a good citron variety to use as rootstock?  Then we'd order those three and split the seeds up among the group.

58
Interesting, thanks!

The reason I'm not worried about trees getting too big is that I figure anything citrus I plant today will be killed by HLB before it gets too big to manage, so it's all about what might be produced in the short term.

Citrus General Discussion / Re: C35 rootstock tree size
« on: June 07, 2018, 10:41:39 AM »
I have Three Citrus trees on C-35 root stock (Tango, Yosemite Gold and Gold Nugget) that are 7 years in the ground.  They average 12-14 feet tall so far and continue to grow. This is a very productive year for all three trees with the Yosemite Gold being the most loaded with fruit.

Johnny

Did you graft the Yosemite Gold yourself or do some nurseries carry it?

Citrus General Discussion / Re: More HLB In California
« on: June 07, 2018, 10:33:35 AM »
This article describes how rootstocks that are part or fully citron seem to survive HLB:

https://fshs.org/proceedings-x/2016-vol-129/FSHS_Vol_129/99-107.pdf

I'm curious if anyone has tried this out combining a few of the things we discuss on this board -- growing citron type rootstocks from seed and approach grafting to create a multi-rootstock tree and then grafting various citrus on it.

This seems to be a source for various rootstock seed, but they only sell in bulk:

61
Interesting, thanks.  I had read that C-35 produces a smaller tree -- do you find it does that by slowing growth or just maxes out at a smaller size?

Tropical Fruit Discussion / Re: Subtropical abiu relatives?
« on: June 06, 2018, 05:47:50 PM »
Ah, interesting, thanks!  Now I just need to find a source for C. imperiale.  I got some seeds from Australia a few years back but they rotted in the mail.

63
Do the leaves smell like pee?
If so it may me Tamarillo.

kj

I think mine smell like burnt popcorn, but yeah, they have a smell.

64
I guess I should add -- if anyone knows of which cultivars / species seem to be showing some HLB resistance as rootstock, that would be great as well...

65
Anyone know what seeds to start from to grow vigorous and productive citrus seedlings to graft onto?  I don't want a dwarf and slow growing tree for oranges, lemons, grapefruits, and other citrus but rather want fast growing and productive trees at the risk of them getting too large.  Any thoughts on what seeds I should plant (and maybe it varies depending on what I want to graft, so I'd be interested in ones for oranges, lemons, and grapefruit)?  This is for SoCal.

66
I don't think it's a that one sahai. The leaves are totally different. I thought it might be a So-Shang fruit tree, I definitely tried to germinate seeds of that fruit but the leaves look too light, and not robust and glossy enough. Plus the fruit is not elliptical.

It doesn't look like any Elaeagnus to me so yeah, I agree probably not So-Shang.

The closest relative with better cold hardiness is Chrysophyllum imperiale, the fruit seem very similar.
Should grow in 10a zone, maybe 9b too. There are very few specimen so it's impossible to know the real limit.

I had thought of C. imperiale as more closely related to starapple, but it would be interesting to see if they're compatible.

Tropical Fruit Discussion / Subtropical abiu relatives?
« on: June 06, 2018, 12:30:34 AM »
What relatives in Pouteria are the closest subtropical relatives of abiu?  I remember Oscar had some highland abiu relatives at one point -- are there others, even ones that are a bit more distant?  I assume lucuma, canistel, etc. are not very closely related but happy to be wrong about that.

69
I have some dark surinam cherry cultivars (Black Star, Lolita), and a funny seedless one selected by a CRFG member in Davis, and will be moving to SoCal soon.  If you have a seedling to graft onto I could give you some scions.

70
Apologies for the necro bump, but does anyone have any recommendations on where to purchase copper hydroxide to make the homemade version of Microkote? Unfortunately the links from are long dead and I'm having some difficulty sourcing it.

We got it on ebay if I remember right.

71
Well Ive never seen any thorns on any Elaeagnus so I wonder if I have a So Shang. Are the thorns only on mature wood?

Not sure I've looked carefully.  I will check mine.

72
I'm curious how they treat lychee -- is it hot water treated or irradiated or nothing?

Tropical Fruit Discussion / Re: Indian Mango season 2018
« on: May 29, 2018, 11:23:06 PM »
I feel it has a lot to do with the rootstocks but in terms of what little we know about Indian varieties grown in roughly coastal inland areas, my friend has a productive Bombay and Kesar and Jumbo Kesar seem pretty disease resistant and sets a good amount of fruit. Another friend has Neelam and Mallika that is productive.

Simon

Interesting -- thanks!

Slightly off topic, but which Indian type mango cultivars seem to do the best for folks in SoCal a medium distance from the ocean (7-8 miles inland)?  (In terms of vigor, productivity, and disease resistance.)

Tropical Fruit Discussion / Re: Avocado thread
« on: May 29, 2018, 03:30:55 PM »
There is 50-100 year old Avocado tree's all over Santa Cruz and 1 commercial farm I know of, I mention for fact only not recommendation , " Abounding Harvest"  ::)

Huge MacNuts in SC too, but not surprised we are not represented on the Map. I think that map is 1/2 truth accurate on the most general of scales.

 California Avocado demission seems like a glorified Guacamole lobbyist group.

Cost of land where they grow well often makes a new investment into the Avocado Orchard game not that smart, unless your banking on long term, and then one good freeze and your screwed.

I've been solely managing a 10 year old Avocado and Citrus Orchard here on about 1 acre. Growing well except idiot landowners keep cutting off the water at all the wrong times and now they sliced up my irrigation lines to install a new 2" main to feed their stupid 5 acres of grapes they just put in. California does not need 1 more stupid grape vine planted anywhere! You see them everywhere in CA spreading like a legal pot growing cash cow.

Interesting about the orchard there.  I'm surprised irrigation is needed in Santa Cruz for a 10 year old orchard -- you get a seemingly-perfect amount of rain for avocados to live off of once established.

Brokaw has a big orchard in the Soledad area (and I assume they're not the only ones) that is also not reflected in the chart...
