LET'S TALK ABOUT FEEDING ORCHIDS 
For a long time it was thought that the only kinds of orchids which would respond 
to a feeding program were the terrestrials and semi-terrestrials. Cattleyas and 
all other epiphytes were believed to be true air plants, requiring only air, sun- 
light and water. 
In fact, there are a great many successful growers who still maintain that 
Cattleyas get all the nourishment they need from those three elements, plus the 
osmunda in which they grow. Some have top quality collections of plants, tending 
to prove their contentions. 
I was one of those who had to be shown that a feeding program could be beneficial 
to Cattleyas. For the past two years I have been feeding certain blocks of seed- 
lings and mature plants regularly once a week and watching their growth. 
As a result, I'M SOLD ON FEEDING! 
A casual glance at those seedlings and plants which have been on a regular feed- 
ing program would, I believe, convince the most skeptical. 
If you would like to see one of these seedlings in a 23 inch pot, I will send one 
of my selection but typical in size and growth of the whole fed group, (shipping 
charges prepaid anywhere in Continental U.S.) for $3.50. 
Far from being "soft" and "rangy" » which was what I had feared when I started 
testing this nutritional program - the fed seedlings not only show increased 
growth, but it is tough, sturdy, broad-leafed growth. Regularly fed mature 
plants carry more and huskier bloom sheaths than ever before. 
Friends who have been helping with this experiment report similar results. 
Following is a typical excerpt from letters I have received from them: 
"Please send me some more of your Orchid Food, as I am just about out. My plants 
all have grown so much since I started feeding with your food that I do not want 
to miss a single feeding." --- J.E.W,, Balboa, Canal Zone.
