Z. furfuracea croaking!
Think I'll give up on this little guy.
Had it for two years, grows one tiny leaf a year.
Now three leaves are crunchy, something's obviously going on
(Duh! ... like DEATH).
Yet my Z.vasquezii and Z. picta are doing great.
It drives me crazy when one plant croaks, and the other 100 are fine

I am not surprised by this, Barb. That is a typical response to drying out. The plant looks quite healthy. I think it will be OK.lucky1 wrote:Glad I repotted today.
The roots were dry as a bone in the unglazed clay pot.
Yes, those little knobs are actually small, immature corraloid roots... which indicates an otherwise healthy plant.lucky1 wrote:Are these little knobs, nodules supposed to be on there?

If the corraloid roots are populated with cyanobacteria, then they are able to fix nitrogen from the air even in winter indoors. If you are really curious, you may want to carefully remove one of those "knobs" and cut it open to see if there is a bluish-green ring around the inside of the "knob" -- which would indicate that the cyanobacteria have been able to get in there.lucky1 wrote:Those "knobs" corraloid roots are for nitrogen fixing?
Does that occur even in winter indoors?

Jody,
I am curious but think I should give the little guy a few days rest in a warm spot before I dig him up again for the surgery. Those nodules are tiny.
Are corraloid roots what miccorhizae cling to as part of a symbiotic relationship?
This is interesting stuff, Jody, thanks for taking the time to explain it.

No. Mycorrhizae attach themselves to the regular fine roots and increase the plant's ability to take in water and nutrients. They are not involved in the corraloid roots.lucky1 wrote:Are corraloid roots what miccorhizae cling to as part of a symbiotic relationship?
BTW, for anyone interested in corraloid roots, I have a couple photos to share. My wife and I started painting the outside of our house over the holidays. To access one side, we had to tie back our big E. ferox (see first photo below). Underneath this plant, I found clusters of corraloid roots -- some quite large -- at the surface. I just went out and photographed the largest cluster (see second photo below). I also removed a small portion of it and cut into one of the nodules to reveal the blue-green cyanobacteria inside (see third photo below).
Enjoy!
Jody

That is interesting, Jody!
Looks like a cluster of bees around a comb.
I read a little more about corraloid roots;
they apparently grow up towards the surface of soil.
Are they coming up to look for algae, which presumably is food for the plant?
Is blue-green cyanobacteria algae, or does it need algae?
So the regular roots that grow downward serve only a partial purpose in feeding the plant?
or maybe just stabilizing it in the soil?
Or am I way off base again?
Huge E.ferox, gorgeous!

furfuracea getting worse
Maybe it just didn't like the new Light Box I installed after Christmas.
It's getting worse despite being kept warm, and now, moist.
Just for interest, I repotted the Zamia picta, and noticed it had no corraloid roots.
But the caudex seems to have grown considerably.

Lots of questions, Barb. It is presumed that the corraloid roots grow toward the surface to gain access to both cycanobacteria (which is the more formal name for blue-green algae) and free nitrogen in the air. The plant is not feeding off the cyanobacteria; rather, it simply obtains the converted form of nitrogen (most likely nitrate) from its symbionts (the cyanobacteria in the nodules of the corraloid roots). The other, "normal" roots function to both secure the plant in the soil and take up water and other nutrients from the soil. Hope this helps.lucky1 wrote:That is interesting, Jody!

One more question.
Sorry!
Would corraloid roots be absent/unnecessary if fertilizers were consistently used (supplying nitrogen/nitrates)?
Thanks for this!

It depends on the quality of the soil, the pH, etc., but in general coraloid roots would be unnecessary if the nutrition of the soil is good. But that doesn't necessarily mean that they will be absent. The plants seem to always grow some amount of coraloid roots regardless of their growing conditions. I have no idea why they do this. Perhaps it is as a result of millions of years of evolution in seasonally variable climates and soil nutrient levels.lucky1 wrote:One more question.

Great pic Lori, nice to hear from you!
I just repotted my little furfuracea with better soil.
Thank goodness it recovered from its near fatal dieback this winter.
Thanks!

You're certainly doing many thing correctly, Gartem!
