Good thinking -- I planted a couple of West Indian seeds on the greenway in Albany and am thinking we can graft them next spring.  Maybe we should prioritize some Hawaiian cultivars for them.

Where are you in Northern CA?  I ask because I've found Sharwil to be a slow grower in the bay area -- might be worth considering putting it on double rootstock if you want to grow it.  (It seems to help increase the growth rate.)

Do you find that you need to irrigate them, or do they make it without water?  Because in the bay area I've seen them grow like weeds, with no water, and are hard to deal with when they grow.

There was someone who posted pictures of an amazing looking lychee tree growing in Long Beach -- maybe it's one of those things that needs a combination of warm nights (urban heat island and warm waters) plus good soil plus extra care (filtered water, acidified soil)?

I'm hoping to try Simon's suggestion of growing a bunch of lychee seedlings and approach grafting -- planted a bunch of seeds recently.

Where did you get seeds of C. imperiale?  I've been really hoping to try it here because I think our climate might be just right.

Get a hose rated for drinking water.  Hoses are notorious for containing lead.

This is something I wanted to add / ask about.  I'd like to get one that's lead free in both fittings and hose and can handle heavy use.

Patrick, I remember being amazed at how well your trees were all doing given how little you water, and that you were on top of a steep hill where I can't imagine there's any groundwater.

I usually go with about 50/50 peat/perlite and that seems to work well.  I don't get mold if I have more peat in the mix but often the peat creates a hard hydrophobic layer on top when it dries, which seems to hurt the small seedlings that are trying to push through.

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.

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.)

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.

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.

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.

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:

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:

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.

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

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.


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

Citrus General Discussion / Re: More HLB In California

This article describes how rootstocks that are part or fully citron seem to survive HLB:

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:

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?

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.

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


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

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...

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.

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.
