Citrus General Discussion / Kanuma as a soil amendment
« on: October 02, 2020, 10:28:49 AM »
Howdy all,
My well water is fairly high in pH and dissolved solids.  It's a constant effort to maintain an acid soil condition, especially for my potted citrus.  I recently got ahold of some kanuma "soil". It has a tan perlite-like appearance and feel and it's very acidic in reaction.  It's a volcanic stone used by bonsai enthusiasts and is imported from Japan.  It's often used straight for bonsai azaleas and other acidophiles.

Has anyone tried this as a soil amendment for potted citrus?  I thought I'd give it a try and see if it helps maintain an acid condition in citrus potting "soil".   Thanks!  Steve H.

Citrus General Discussion / Low biuret urea?
« on: February 27, 2020, 04:55:13 PM »
Howdy all!

Can anyone tell me if biuret damages all parts of citrus trees, or just the leaves?

I have a lifetime supply of a generic 30-10-10 soluble acidifying fertilizer la Miracid.  I don't know its sources of nitrogen but I've used it on citrus roots many times without obvious damage. What type of nitrogen did acid fertilizer contain 25 years ago? That's when I picked up 200 one pound packages of the stuff.  I transferred them to 5 gallon buckets and don't have the original label.  It was a great deal.  Through a weird combination of a sale and rebate the store paid me a buck and a half for each box I "bought".  Needless to say I took all they had and made $300 in the process. I still have about 50 pounds.  Which should last me a while.  Thanks! Steve H

Citrus General Discussion / Ancient lemon cultivation?
« on: May 24, 2019, 06:18:28 AM »
Howdy all,

How do you grow a lemon in a pot for a hundred years, or two or three centuries? The Italians can do it. What's their secret?  Composted pine bark, perlite, turface, plastic pots, no heater outages.....osmocotio?

Citrus General Discussion / Xie Shan in a pot?

Xie Shan in a pot?

Howdy all,

I've got a gallon XS on Flying Dragon. I intended on planting it (in-ground) in my greenhouse. I just got a 3 gallon Hirado Buntan (on FD) I couldn't resist from Harris, a beautiful tree. I have space to plant one more tree, anything else will have to remain in pots. I'm now leaning toward putting the HB in the ground and keeping XS potted.
Here's my dilemma: Although I've never tasted it, XS is supposed to be the finest, earliest satsuma. My experience with mandarins (I have 3 in-ground) is that they take several years to produce good or even just edible fruit. And I've read that XS is supposed to take longer to flavor up than most. If XS takes a long time in the ground will it ever taste great when grown in a pot?
So.....if you grow XS:
What rootstock is it on?
How long have grown it?
What size pot do you have it in now?
What potting medium?
What's your temperature range?
And most important of all, does yours taste great?

Citrus General Discussion / C-22 rootstock?
« on: June 16, 2018, 12:40:04 PM »
Howdy all,

Does anyone have personal experience with the C-22 rootstock? It was released a while back as 'Bitters'.  I've read what I could find on line, but commercial growing experience doesn't always correlate well with home growing.

Thanks! Steve H.

Citrus General Discussion / Pavlovsky lemon
« on: March 14, 2018, 09:27:53 AM »
Howdy all,

Has anyone heard of or grown the Pavlovsky lemon?

It appears to be a lemon that was selected by residents of several central Russian cities over the course of two centuries specifically for growing in the home. Looks like it's offered by several eastern European nurseries.

Citrus General Discussion / Xie Shan Q

Howdy all,

Can any of you Xie Shan growers out there tell me what the tree's natural growth habit is?

Thanks,  Steve H

Citrus General Discussion / Finger Limes anyone?
« on: March 07, 2017, 08:40:06 AM »
Howdy all,  I'm looking to add a finger lime to my growing greenhouse citrus collection.  I see a sort of generic green available everywhere on line. Anyone know where I could find named cultivars? (Yeah I know, Oz.)

The clones I see on Australian web sites are of various colours and  degrees of seediness, but they're also clearly described as to shape and size of bush/tree. Narrow and shrubby works for me. Any thoughts?

What about rootstock?  Maybe FD? Or is that going to be too stunted, or even incompatible.

Thanks, Steve H  SW Wisconsin, USA. USDA Zone 3
