Citrus General Discussion / Re: Dead bearss lime tree
« on: May 30, 2020, 11:27:46 PM »
The simptoms are that of Armillaria fungi.
Look into Armillaria root rot.
Sort-of, except that I have not seen mycelia under the bark and there also were no mushrooms under the tree in the winter. Oak root fungus definitely is around, so it's plausible.

Citrus General Discussion / Dead bearss lime tree
« on: May 30, 2020, 02:59:59 PM »
This winter our Bearss lime tree, planted in 2002, started to look sad. Overall thinning of foliage, twigs drying out. An algerian clementine that is about 12' away showed similar symptoms a few years ago and looked like it was going to die but after 2 almost-dead years it recovered and provided us with fruit for 5 months this spring. About a month ago the bearss lime went from looking sad to dead in maybe a week. I noticed that the bark peels off easily. I don't see any oozing. Location is Santa Barbara, sandy soil slope. I've gone through citrus disease keys and can't really nail it. Any thoughts about what the most likely causes are given soil & location?


This phot was taken after I removed the easy-to-peel bark, which is shown a couple of images down.

Temperate Fruit Discussion / Re: Best apple varieties for zone 10b?
« on: March 05, 2020, 02:23:51 AM »
You may be interested in this list: http://www.kuffelcreek.com/applelist.htm

I only have a few varieties but so far my experience matches. Specifically, Pink Lady is great, and Ashmead's Kernel is mediocre (got the budstick I grafted from someone living nearby in a much colder microclimate and his is delicious).

Before this turns into a perlite war  ;D let me say that some of the plants will eventually find their way into the ground while others may stay in pots. I don't know yet :-).

Lebmung, isn't your formulation too water retaining while the plants are in pots? Also, what would you use instead of coco coir: I've banned it due to the risk of salts (ruined several years of veggie starts and potted citrus before figuring that out, it's not that the coir is bad per-se, it's that I don't know where I can buy "guaranteed" salt-free stuff).

I know there are lots of fans of Turface, I just can't bring myself to invest in that...

In terms of worms as a potting mix ingredient, funny thought, my experience is mostly that I can't keep-em out! (not that I'm trying)

Is it just me or do others also find the "traditionally grown" tree in the photo better looking? Yeah, the other one is taller but it's just a slanky stick. The "traditional" one is bushier and seems to have more mass.

Citrus General Discussion / Re: Mandarin/Lemon recommendations
« on: March 03, 2020, 12:51:11 PM »
I'm also looking for a new lemon... The difference between lemons is a bit of a mystery to me 'cause it's not like I can go somewhere and buy multiple varieties to try them side by side...

I have a Eureka (Frost, I believe) that has issues (half broke off due to wind) and a meyer, I have some Femminello Siracusano 2KR from CCPP that hasn't gotten to fruit yet. Is there a lemon that is smooth and thin-rind like the meyer but has regular lemon flavor? Oolje, what do you find fantastic about the Femminellos? SoCal2warm, do you find a flavor difference in the juice between Lisbon and Eureka or just appearance, or ?

Thanks for the replies! I hate working with perlite hence pumice, but I could report a couple of these little guys into 1:1 peat-perlite just to see. Questions:
- I would have to liquid fertilize or add slow-release fertilizer?
- How long should I expect to wait before seeing results either way? (They're in a greenhouse around 80F during the day and 55-60F at night in SoCal.)

I'm now wondering whether I concluded prematurely that they got overwatered and the issue is more like transplant shock. When I came back from my trip I took two out and examined roots and found the root ball soggy due to the original mix they came in, but I didn't really see rotten roots. The seedlings came in a very fibrous mix in pots (really more like tubes) 1" dia by 5" long. When I potted them up the roots had reached the bottom and formed a web mostly around the outside of the mix. I held them in the 24oz cups and filled my mix around the root ball. Mystery :-(

Citrus General Discussion / How to keep citrus seedlings growing
« on: March 03, 2020, 01:33:50 AM »
I've been rooting citrus cuttings for a number of years and recently started to germinate seeds. Plus I bought some C-35 and some Flying Dragon rootstock from four winds growers. Invariably I end up with problems when the seedlings get about a foot tall. Often it's my fault: I over-water or I forget one and under-water it, or I don't see the scale insects attacking the plant until it dies back.
Is there a "recipe for success" for watering these small plants and, related, is there a trick to get such stressed seedlings to get growing again? I've now had a couple that are about a foot tall, have 2-3 leaves, are green, but have not done anything in a year. Their roots are small but not rotten.

As potting mix I use half pumice and half the E.B./Stone citrus&palm mix (https://www.ebstone.org/products/eb-stone-organics?tab=outdoorsoilamendments#citrusandpalm-439) and I fertilize monthly with their citrus "plant food".

Some pics...
Here are 4x FD rootstock from 4Winds (left) and 4x C-35, received late january.


I repotted the FD as the roots were filling the tiny pots:


Unfortunately I didn't calculate the automatic watering correctly when I left for two weeks and the FD got overwatered as far as I can tell. (I should also have completely removed the very water retaining mix they were in as opposed to just filling my mix around the existing one.) Now I"m struggling to get them "restarted".. (Sorry for the bad photo with all the mess in the background.)


I've only recently started to use the transparent cups for the small plants after seeing that use on ourfigs.com. I need to put some paper wrappers around them to block the light, but so far there are not enough roots for this to be an issue :-(. The mix is very well draining but perhaps the 6 small holes in the cups are not enough. I'd love to experiment, but I find that it takes a very long time to see whether things are improving or not, typically the plant just sits there do nothing either way for a looong time...

Any help appreciated!

Citrus General Discussion / Re: Tree Dieback??
« on: June 01, 2019, 09:10:01 PM »
I have some trees that tend to have similar problems, with leaves dropping, twigs dying back, etc. After lots of head scratching my conclusion is that it's most likely due to temperature issues ("Winter Leaf Drop"), such as warm air in the greenhouse with cold roots in the pot, excessive day/night temp variations in the GH, cold air close to the greenhouse wall, etc. Not saying this is your problem or that I diagnosed mine correctly, but something to consider...

Citrus General Discussion / To peel seeds or not to peel..
« on: June 01, 2019, 08:52:31 PM »
I got a bunch of Taitri seeds from a generous forum member (thanks!!) and planted them about two weeks ago. I read about peeling the seeds and out of laziness decided to run an experiment (this way I only needed to peel half of them  ;D). So I put 10 peeled and 10 unpeeled into soil blocks and kept them at 80F bottom heat. In the photo below the left "column" has the peeled seeds and the right one the unpeeled ones. (I did not scarify any of them.)

The photo was taken a couple of days ago, by now all but one of the peeled seeds have germinated and only one of the unpeeled ones... Of course this is not a controlled scientific experiment, but I know what I'm going to do in the future with citrus seeds!

The best suggestion SB could offer was to try to find an old millivolt thermostat wit a mercury switch and mount it on a slant.    My, what a helpful suggestion that was.  How can I operate the SB at near freezing temperatures? Or is my desire to heat without electrical back up doomed?
Mounting at a slant sounds like a good idea to me... Your last post is a year old, so may not be relevant anymore, but if you have a friend who is handy with electronics he/she may be able to build/adapt an electronic thermostat for you, it really just takes a couple of components. The trick is that the thermopile can generate plenty of power for the electronics, just needs an appropriate boost or buck converter.

What does the white cover do to your soil temperature? Might remain too cold?

Citrus General Discussion / Re: Current UCR budwood prices ?
« on: May 23, 2019, 02:44:49 AM »
It's pricey for out-of-state orders. I believe that the minimum is 12 buds per variety vs. 6 in-state. On the plus side, you seem to always get more buds than you order. I ordered one budstick of a bunch of varieties and got two for all of them. The email I use is for Rock Christiano, which is firstname.lastname@ucr.edu and he does reply.

Be careful if you buy a Valencia commercially (as opposed to graft CCPP budwood). I haven't seen anything other than the Midknight Valencia for sale in CA. It's seedless, that's why it's everywhere. It's reputed to be a slow grower and by that measure mine fits right in :-(.

If the grower was La Verne Nursery, I think he told us on the last CRFG LA Chapter nursery tour they use Fuerte seedlings.
I inquired about ordering some Avos at LaVerne and got the following reply: "The avocado rootstock is Zutano and the height we ship at is about 42” from the ground; we use a 42” stake and it will be at top of stake, the 5 gal container is 12” in height." from Richard Wilson - CEO, on April 24th.

Citrus General Discussion / Re: How to promote new growth on Scion?
« on: May 17, 2019, 01:01:16 AM »
Until the scions are completely brown and dead: don't give up! I grafted buds at the wrong time of year (august) and they sat there for 6 months until the right time came along and then started doing their thing. Won't do that again... Even if the scion dies, don't stop, just wait for the rootstock to come back and graft something new the next year :-). I'm sure you can tell I have experience with that, ooops.  ;D
So, can one rate the graft quality by the number of rootstock buds that sprout? E.g., a one-sprout graft is better than a three-sprout graft? Hmmm, I guess the number of available buds, i.e., grafting height, must play a role too?

Ok I did the experiment this afternoon.
Interesting! Do you have time & energy to repeat the experiment but eat the whole fruits instead of making juice?

Tropical Fruit Discussion / Re: Air pruning pots--opinions?
« on: May 15, 2019, 01:14:58 AM »
Seems like it would be difficult to get plants out of an air pot with all the bumps and verticle walls.  You take a tree in a regular pot and turn it over and tap the pot and it slips right off.  I like to turn my plants over and slip the pot off sometimes to look at the root system and see if its time to up pot or plant out. 
Don't you just remove the "button" that holds the air pot together and then unwrap the sidewall?

Boooo  :'(, thanks for posting the update! I just ordered two Air Pots, and 7 Ultra Oxy Pots. I'm trying to get 10 pots from Litgrow, which would be the cheapest source. I'll run my own (no scientific) experiment to see whether I like this type of pot. I don't quite understand the huge price difference when compared to normal pots...

Here I see the limit of my English... ;)
Hey, you did great, plenty clear! I find it great that there are people from Europe and other places on this forum and if that requires some language bending and/or translation, then that's fine with me. I think it would also be fine to post a paragraph in duplicate in your native language.

Interesting: "Powerdrain Isostud must be backfilled within 15 days of installation to protect the membrane from prolonged exposure to UV rays."
At that price it's worth experimenting, though!

Well, so far the ones I've looked at state "do not expose to sunlight for more than X months" where X is pretty small. :-(
Did you get the Dörken Delta MS by any chance?

Oh, I misunderstood your previous post, I thought they were of freshly grafted plants  ::). Now it all makes sense. Thanks for the clarification.
