Target N for Masdevallia @Slipper orchids ? - Orchid Board

keith · #1 (**permalink**) 09-02-2009, 07:01 PM

Hi ,
I am going to use a MSU based feed and want to know what target N for Massies and slipper orchids .
I am going for the 125 N target but my main collection is Masdevallia ,Paphs and some Phrags so am aware that these may require less feed ,if so i will feed all my plants the lower target N but what should i settle with .

Is there anyone out there feeding these species without problems to a target N of 125 ?

Regards Keith

There surely is someone who uses this feed and grows Masdevallia

I have settled on approx 100 ppm N @ 0.6 teaspoon per gallon .
So will now see how they go on MSU feed .

Keith I have started concentrating on my plueros more now. I use Dyna-grow at half strength

I also only feed my masd. and other plueros once a month. so far it seems to be working nicely.

Sorry I didn't see this sooner. I target 125 for my Paphs every watering, same for my Phrags but every other or every third watering, Plueros I target half that 50 - 60 ppm.

I use 125 ppm N for everything (including the Masdies.) I water the Masdies mostly with RO water, then once a week or so soak them in fertilizer mix. Everything else except Dracs get a steady diet of fertilizer mix. Dracs are treated like Masdies. Hope this helps.

Hello Ross , have you seen any leaf tip burn feeding at 125 ppm N ?

I have almost settled on feeding at 100 ppm N for my Masdevallia and 125 ppm N everything else .

Thanks Keith

Nope! But I don't feed regularly with Masdies. I feed constantly with slippers. Masdies don't burn at all for me, but sometimes I get leaves that distort like they don't get enough water. I attribute this to too much fertilizer and back off. I still plan to stick with 125ppm but alternate with pure water.

Same thing happened to my masdies. The leaves turned a very dark green . Put out alot of growths but no flowers.
