Fertilizer 3-1-2 ratio

[Intruder]

The ratio 3-1-2 (N-P2O5-K2O) is currently describe as the ideal ratio for foliage development. Is it able to make flower an orchid if I use a such ratio all the year ?
On the fertilyser market, for what I know only the 9-3-6 of Dyna-Grow exists (if there still exists).

In my many years of growing, I have seen "the ideal fertilizer" change as often as Imelda Marcos changed shoes. Every manufacturer will make that claim, true of false. The bottom line is that what is "ideal" for one grower with one genera in one environment may not be the answer for another grower with other genera in a different environment. Research also has tended to change what we now know about how to stimulate an orchid to best production.

You have obviously done some research and if you feel this ratio is best for you, I suspect you may have to find a source "off shore" to purchase it. There are several members of this forum who are very knowledgeable on where to find orchid products and will ship to your country. Ray, of First Ray Orchids, I would put on the top of my list.

Good luck,

The more I learn about plant nutrition, the more I understand that managing the amount applied is more important than the formula - within limits - and that less is better than more.

Your 3-1-2 product is fine, as long as it also provides the secondary and trace minerals.

3-1-2 and 9-3-6 are basically the same levels, just different dilutions…

Now, the devil is in the details, it'd be interesting to know what's in it also and compare. The number are not everything, how you use them and what it means for the other elements is too.

Yes your orchids will bloom very well using a 3-1-2 formula. It's a good formula to use all year long.

Dynagrow 9-3-6 is a darn good product and will grow fine plants as the above posters agree. It was originally developed for hydroponics. You might consider supplementing it with some liquid seaweed once or twice a month.

Thank you Orchid 126. This is what I am doing since one year with the MSU with great succes.I asked this question because I am looking to decrease the K in my orchids regime. A 3-1-2 ratio sames to me to be a good alternative.
