Masdevallias feeding

[Intruder]

What is your typical fertilization program for masdies expressed in nitrogen concentration and fertilyser distribution frequency? Many thanks for your informations.

Intruder, where are you growing, under what conditions and how old/large are your Masd's?

I am living in Belgium. My Masdies are potted in terracotta pots 4" diameter with a substrate made of fine bark, perlite and sphagnum. From May to September they are outdoor (night T° 12°C day T° 25°C) and during winter indoor (night T° 10°C day T° 20°C) Relative humidity 40% to 70%. I have Masdevallia veitchiana some primary hybrids like Masd veitchiana x Masd decumana, Masdevallia barlliania, Masd. ignea and Masd coccinea + a few complex hybrids.

jtlqh grows masds to the max. If she doesn't see this thread, maybe you could send her a pm. I do not know enough to answer.

The one masd. that we grow here gets fed a balanced fertilizer once a week during the summer months along with our paphs. It is too hot here to really grow them well, so we keep this one against the kool-cell all the time. It stays damp, but seems to not mind.

Cheers,

Replying to get this on topic again
I am using the MSU ro feed @75 ppm N @ every watering with Humate added every two weeks .I also use KLN on poorly rooted plants & superthrive when i feel like it .The superthrive i will probably stop using once i run out but i do love the smell so i am hooked on it not the orchids
I am getting some yellowing leaves with green in the middle section ,but look at the roots which are doing great so am not putting it down to a feeding problem .
I am growing in CHC ,and aim for a ph of 6.0-6.2.
I sometimes give them a shot of epsom salts and love to foliar which i do most days.
Obviously more tweaking will be done .

Just a update, I have had good success with the for mentioned regime with great root growth, the only thing I will be changing is stopping the superthrive. I think the 75 ppm N @ every watering is good for Masdevallia or 1/4 strength every watering in comparison. The yellowing leaf problem is no longer a problem!
