When to start Flowering Fert.

[RosieC]

That's interesting Ray. I stopped using my bloom fertiliser when it ran out but I've not had a problem (still getting spikes) but that probably means what I'm using is not high N.

I use your calculator to determine fertiliser strength based on the N value. Is that a level which should be OK for blooming. Do you have any experience of what is too high?

I use a balanced 20-20-20 orchid fertilizer from March through November and get some pretty darn good blooms. I'm a big fan of keeping things simple, which is backed up by most of the major nurseries out here in Hawaii.

Edit: Whoops, I already said this early in the post. My bad. This thread is kind of old and forgot what I said earlier.

A steady diet of 30-10-10 can affect things negatively.
