Default Fertilizer


I use the Baker's culture sheets a lot and I often read this about fertilizer:
"After new growth is mature, use a fertilizer with less nitrogen and more phosphorus to allow the new growth to harden before winter and to promote better blooming the following season."

I currently use the liquid MSU fertilizer for pure water. Is there a fertilizer that anyone can recommend that has less nitrogen and more phosphorus so I can use it in the Fall?

Thanks in advance,

You are using one of the best fertilizers on the market . Why change?
There has been several reports written on use of low phosphate fertilizers for growing and blooming orchids. Year round use will give you great results.

Thanks Jayme.

I'm not sure I 'want' to change, but I keep reading that I 'should' change in the fall, to promote blooming. I don't know if there's a better fertilizer that has 'less nitrogen and more phosphorus'. I keep reading to use it in the fall, but no one ever gives a name so I don't even know what to use. So far I've just been using the MSU year-round and it's been great, but I wonder if I could use something better for the fall season.

Lisa, I would think reducing the frequency of fertilizing in winter would essentially have the same effect. I think there have been studies done that show increased P does nothing to promote flowering. Too much N can prevent blooming. I've been feeding straight through at 125ppm N. Nearly everything I have is blooming or about to.

Those are my principles and if you don't like them......I have others.

If you want something high in Phosphorus try Better-Gro Orchid Bloom Booster. It is 11-35-15. I alternate with the regular fertilizer one week out of four year round. I think it's a good idea to mix things up a little. After all, in the wild an orchid isn't pooped on by the same bird (with a constant diet) at the same time each week.
