Switching back to a balanced fertilizer.....
In 2010 I started using a MSU type, low phosphorus, fertilizer on the recommendation in a book I had read. In the fall of that year my plants were doing very well but I noticed that I wasn't getting as many flowers as normal. So in the begining of 2011 I switched back to a balanced 20-20-20 fertilizer. Now the fall is here an I'm getting significantly more flowers than last year. In fact my Cattleya Jenmanii had two flowers per stem last year has 5 flowers per stem this year. My other orchids are showing the same kind of improvement. I know that the fertilizer that works best for me may not work for someone with a different water quality or culture techniques. I also understand that there are many variables that can affect the way a plant flowers other than the fertilizer it's getting. But for now I'm going to stick with a balance fertilizer.
