Two andreettae

I love these!:smitten:

Eliseo,

What micropetallum species are you growing with added lime or other pH amendment?

 

[eteson]

Tom, just kovachii but my conditions and skills are pretty bad for this species... i've killed about 10 plants and have a few remaining.

Eliseo,

Are you using Wuxal Calcium on all your Phrag species at the 50 ppm N rate alternating with K-Lite ?

Thanks, Tom

Yes that is correct. I know that my diet would be extreme but it is working very well under my conditions for Phrags.

Wuxal Ca is a foliar fertilizer whith Ca and Magnesium; 0%P and 0%K

Total Nitrogen (N) 10.000%
Soluble Calcium (Ca) 10.700%
Soluble Magnesium (Mg) 1.200%
Soluble Boron (B) 0.050%
Chelated Copper (Cu) 0.040%
Chelated Iron (Fe) 0.050%
Soluble Manganese (Mn) 0.100%
Soluble Molybdenum (Mo) 0.001%
Chelated Zinc (Zn) 0.020%
The cationic micronutrients (iron, copper, manganese
and zinc) are fully chelated (EDTA).

I alternate this fertilizer for one week and K-lite the next one... always at about 50ppm of N and I do not use dolomite lime in the growing media for andreettae.

Sometimes I add diluted "dragon´s blood" (Croton sap) to prevent infections but I do not know the exact composition of this compound...

You might try dropping to 5-10ppm N rate.

My fisheri and kovachii are doing very well at this very dilute rate (also no dolomite added). But I have been adding back a bit more phosphate and sulfate. I took magox ("milk of magnesia") and neutralized it with phosphoric acid. Then added some epsom salts, and a dash of ferric sulfate.

I only add enough of this to boost P to 3-5 ppm.

I just got one of Tom's P vittatum seedlings and so far it's growing well on this too. (keep fingers crossed).

Interestingly enough, the folks who make Wuxal Calcium market it as a foliar feed, not a drench.

Eliseo,

I have two more questions: What is the TDS or EC of your final irrigation water? And are you using R/O water or water from your municipal source or well?

 

[eteson]

Hi Tom, my final TDS is about 300 ppm. My water is from the municipal source, and it comes at about 70 to 100 ppm. I do not know the mineral concentration of my source of water, sorry.
