I have a 75k modine hot dawg.  I actually have another backup one I havenít installed yet.  Plus four ďmr heaterĒ screw-onto-20lb-grill-tank heaters as emergency backups that require no electricity.

I have a battery powered radio thermometer alarm, and an internet enabled alarm that sends text messages. 

I think having redundancy and backup plans is better than relying on a single unit

I just noticed all the replies to this thread.  I discovered I actaully have a few other trees that have the same symptoms.  I have some Agri-Fos that is probably four years old - does it go bad?

Brian, I doubt that the high humidity in your greenhouse has anything to do with your tree problem.   Humidity in my greenhouse, especially during the winter months sometimes causes "rain" to fall from the glazing.  On warmish days I turn on the exhaust fans to reduce the humidity.  However, over the 30 years I've had the greenhouse, I have never had a problem.  In Florida during the summer many days the humidity is 100 percent.  On Okinawa, when I was in the Navy, the humidity was near 100 percent the entire summer, no problem with the citrus.

Did you mean to respond to me other thread regarding the gummy areas near twig dieback?  If so thank you for the information, I have always worried about humidity and it is good to know it can be tolerable.

Laaz do you water the container trees you overwinter in Your garage?  Or do you let them dry out?

Citrus General Discussion / twig dieback with gum at branch crooks
« on: November 03, 2018, 10:19:39 AM »
One of my fukushu kumquats has experienced signficant twig dieback in the past month or two.   This is the largest one I have, and the only kumquat I've planted in-ground in my greenhouse.  I noticed when cutting off the dead branches and inspecting the damage that there are blobs of gum at joints of the dead branches.  I've never seen this before, does this indicate anything out of the ordinary or is thjis common with twig dieback issues?

Now, I suspected the cause for the dieback was a rather severe cottony cushion scale infestation that I let go on too long while I fiddled with hose-end sprayers (I ultumately gave up and went back to a pre-mixed pump sprayer).   Its also possible that this is somehow related to the clay soil the tree is planted in, or the high humidity of the greenhouse.  However none of my other 40+ trees have this symptom, and many of them were infested with the same scale and sprayed for it at the same times. 

The kumquat is from Fourwinds, not sure which rootstock they used for kumquats.

Looks really nice.

Is that the knockoff rootmaker roll material?  How does it hold up?  I saw it years ago when it was only available on Alibaba and it wasnít straightforward to order direct.  Whereíd you find it?

Hereís the thread with the article.  I suspect this type of hack is the future of selective breeding

Iíve always been interested in this but I speculated there must be a way to cheat and induce maturity into an immature seedling.  If I remember correctly scientists in Spain did just that using CRISPR.  That was the last I heard of it, and they didnít respond when I asked for more information.

Of the trees I've owned that had severe dieback, about half died and the other half bounced back and are very healthy again.  With new soil your tree may recover in time.  Make sure the container drains well.

I've been wanting to go to the SE citrus expo but November is the busiest time for me at work so it is hard to find a good time to take off.  I'll let you guys know if I can actually make it down there.

Citrus General Discussion / Re: Variegated pink lemon tree tips?
« on: October 19, 2018, 04:16:43 PM »
Mine is in a container in a heated greenhouse.  A container is probably good for you if you have any chance of frost in the winter.  I see your zone9 low temp is ~25-30F, so you should move it indoors if there is a frost advisory.

I use osmocote plus 25-5-15 (the pink bag, most common type) to fertilize, and a free draining soil mix.  You should change the container soil every year, and move it to a bigger pot then if the roots are circling around.

Also, you may have Citrus Greening disease on your area, aka Huanglongbing.  I'm not sure how widespread it is in Florida.

Congratulations!   Itís a nice tree.  I have one of these but mine is only half that size.  The pink striped lemons are really novel.  Care is the same as any other citrus tree.  Are you keeping it in a container or planting in the ground?

Persian/Tahitian lime is pretty much perfect, and itís easily propagated from cuttings.  What donít you like about it?

Ah, thanks for the reminder.  I have been meaning to plant a FD tree outside somewhere in hopes that it will eventually fruit and produce rootstock seeds.   I don't have a good place for it yet, I need to think about where to fit it.

My heater kicked on for the first time last week.  I have it set to 55F and so far it has been working perfectly and cycling 3 times per hour which is ideal.  I installed two ceiling fans in preparation for winter based on your recommendation, and they are fantastic.  I feel I don't even need horizontal fans with the ceiling fans running, and they take up no floor space.  I have them set to turn on automatically any time the vents are closed.

My greenhouse is now quite crowded as I brought in some herbs and tender perennial flowers, and I have some tomato and pepper plants growing also.

I noticed a similar looking white fuzz on my trees after spraying for scale.  It looks to be a fungus growing on the cottony-cusion-scale corpses.  Mine isn't in thick patches like yours, though, not sure if its the same.

how big are your trees?  There was a guy on another forum who would constantly post pictures of his setup:  two 5gal home depot buckets lined with tinfoil and a light bulb on top, in a clamshell arrangement.  Seems like a good design if you don't care about appearances and your trees are still small enough to fit.  Maybe a heat mat on the bottom if roots don't get warm enough.  I think he was using a blowdryer or something that seemed kind of wacky.

« on: September 23, 2018, 10:44:17 AM »
You might not need much fertilizer over the winter in canada as you likely won't see much growth.  You should be fine using your liquid fert as foliar if you reduce the concentration.  I believe I've read foliar fert is absorbed at 10x the rate compared to through roots, so you'd use 10% of the concentration.  Also I've heard foliar feeding of iron-containing fert isn't recommended.  I've done foliar feeding with a liquid fert that contains a small amount of iron though with no issues.  I don't know what a safe amount is, could never get a clear answer.

Citrus General Discussion / Re: Keeping Kumquats?
« on: September 21, 2018, 05:55:52 PM »
Brian-Did the taste of the variegated kumquat ever improve for you?

I'm in zone 7 so I'm wondering to what month/temp I can keep the kumquats outside?

I lost last years crop as the tree had an unhealthy spell.  It has a good number of fruits on it now that aren't ripe yet.  I will find out fairly soon and report back.

Kumquats go into a semi dormant state as it gets colder.  They have done very well for me when other citrus have struggled when I was carrying them indoors in the winter, before I had a greenhouse.   They are listed as being able to handle temperatures in the mid-20s I believe but if you have small trees in containers I would avoid letting them freeze at all.  I always brought mine in when nights started dropping below 40F.  Be mindful that if your house is warm enough they will break dormancy and then may struggle from lack of light.

The name given on that link is "Giant Kumquat (Fortunella margarita Nordmann seedless)"  so i assume it is the usual nordmann seedless which I've never had seeds show up in.  The fruit is elongated just like that.

Unless there is a giant version of nordmann I'm unaware of I believe this is just being embellished a bit in Italy :)

Hah - I was going to say that picture looks like a closeup of a nordmann seedless nagami kumquat, with a lemon photoshopped in on the top center.  And indeed that seems to be the case... first google result I found for kumquat grosso is

I have some giant kumquat which is similar to Meiwa( sweeter and dryer) but at least that has few seeds.

Can you tell us a bit more about this giant kumquat?  Any idea what variety it might be?  The largest kumquat I'm aware of is the nippon orangequat.  Next largest would be "red lime".

Citrus General Discussion / Re: Keeping Kumquats?

I'm not aware of any seedless meiwa, only seedless nagami (nordmann).  Is that what you mean?  If there is a seedless meiwa I would love to get one.

My first batch of meiwa was very dry and awful.  However my second crop was more juicy and was excellent.  Because of this I'm hesitant to judge a variety too much until I've had a few crops.  For something in between, Marumi is really good.  I think its better than meiwa and almost on par with fukushu/changshou

I am fascinated by kumquats and have collected nearly every variety.   I have a thread I've been updating with my opinion of the various kumquats & their hybrids:

Definitely try the meiwa fruit, it is much sweeter than nagami as it has less juice and more pulp. 

If you don't like meiwa either, you probably just don't like kumquats as meiwa and nagami represent the sweetest and most sour ends of the kumquat spectrum. 

Citrus General Discussion / Re: Rooting Root Stock?
« on: September 12, 2018, 12:43:22 PM »
This is interesting.  I was wondering something similar when I was disposing of branches I'd cut off FD rootstock to get them out of the way when grafting (they were crowding my target area).   Because my trees are in a greenhouse the lack of taproot isn't a big deal to me as there is no wind to uproot trees.  And FD seeds are hard to come by for me.

I'm going to try propagating flying dragon rootstock by cuttings.
