Desert lime in pot

[Walt]

I have a problem that hasn't been discussed here as far as I know.  The town I live in takes its water from the Saline river.  And like the Colorado river, more water rights have been granted than there is water.  A stupid but very serious problem.  So the last two summers, it has been against the law to water lawns, water trees, fill a swimming pool, wash your car, and maybe other things I don't remember just now.  It is no law against watering a food garden.  So OK.  I interplant tomatoes, onions, peppers, etc. between my citrus.  If my citrus take some of the water, that seems to be OK.
But to reduce my need for water in the long term, I bought a desert lime Eremocitrus Glauca, from Madison and it came yesterday.  It looks good but of course it needs repotting.  So I'm guessing it might prefer a better draining potting mix than other citrus.  Anyone with experience with this?

How did you manage to get one?  For several months I've been on the notify list for when they become available, and I've heard nothing.  Another question: what rootstock is it grafted onto?  (their site says that they are grafted)  It would seem that the soil mix should be chosen according to the needs of the rootstock, rather than according to the scion.

I keep mine in the same soil as my other citrus. This was my first year with flowers

I also received mine from Madison 2 days ago. It's grafted on US 942. I'm hesitant to keep it outdoors in zone 8b/9a, I'm not sure how much cold they can take as i've seen many numbers online.

The lowest we had during the freeze this January was 22.

I'm hoping to get one to use for breeding, to mix its traits into my diverse semi-hardy population here.  Does anyone know if it can be equally useful as both a pollen donor and as a seed parent?  Are there specific conditions required to initiate bloom?  I already have a hybrid that was sold as "Razzlequat" many years ago, but it has never bloomed for me, when other citrus have already done so for many years.  I'm wondering if that family perhaps requires more heat or dry spells to initiate flower buds?

If it's grafted on US-942, it should be able to handle a variety of soil conditions. We have US-942 on its own roots in clay soil and doing very well.
I have Eremorange and Eremomandarin plants growing, and hopefully just enough plants to propagate more for next year as well as test some outdoors. I'll be skeptical of their hardiness here until proven otherwise!

I used to have Citrangeremo but it died to a low of 12F a few years ago. Granted it was very recently grafted and should've been protected.

Mulberry0126:  Will you have the Eremomandarin and Eremorange for sale?  Or any other Eremo relative?

I have a razzlequat, grafted, growing in 90% bamboo biochar. Tiny as yet, lost some growth last summer to fertiliser burn. Has a flower bud on it currently.

I got an email about 10 days ago saying Madison had a few and I went right to their site and ordered.
It makes sense that the root would determine how it is to be potted.  Thanks.
I know it won't be hardy here.  Nor will an F1 hybrid with Ponciris.  Maybe some from a backcross to Ponciris will be.

re:

"What was your overwintering temperature for the razzlequat that has produced a flower bud?"

Razzlequat was overwintered at about 50°F, weak natural light. Basicly parked in front of a window in a disused room.

By next year, yes. I'm establishing the mother plants so I'm doubtful I will have any for sale this year outside of a few extras for auction.
