How often to fertilize
I bought thid beautiful orchid ( Phalaenopsis ) with about six buds and
3 already opened. The culture that came with it said to fertilize once a
month. A knowledgeable friend said he does his at every watering and had
no problems. Of course I forgot to ask what strength. I have 15-30-15
and 20-20-20. would too much fertilizer kill it? BTW, i read in this
group some people mentioning "sheath". What is a sheath?
