ae Young orchids when fertilized have gained in growth, over unfertilized orchids, 
by as much as one year in three years of treatment. 
b. Correctly fertilized orchids have been more uniformly healthy and vigorous. 
c. Fertilized orchids have made more new shoots, and have lost comparatively 
few leads. : 
d. They have grown more rapidly and frequently have saved one shift in repotting 
by permitting repotting in the second size larger pot—thus saving repotting labor. 
e. Labor is also saved by feeding and watering in one operation. 
f. By using Wilson’s Orchid Fertilizer as recommended no toxic residues are 
formed and the orchid plants are fed sufficiently, but not to excess. 
Orchid plants do not need an excess of phosphates. The lower phosphate content 
improves the water solubility of the mix. 
Seite No. There are too many cases where poor growth is due to environmental conditions 
such as light, temperature and humidity. 
No. The acidity objections to all-purpose water soluble fertilizers have been over- 
come in Wilson’s Orchid Fertilizer. It is neutral in action and in continued use 
no deleterious acid or alkaline condition of the sub-stratum will be evolved. 
No. Not if it was in solution when first prepared. 
The proper amount should be put into the correct amount of water and stirred up 
well. When it has entirely dissolved drench it on the orchid pots with a watering 
can. In large greenhouses it is advisable to prepare a tank and pipe system as is 
used in many establishments for this type of watering and feeding in one operation. 
Do not use a spray or “rose” nozzle. Use the open hose and drench each pot. 
None. While there have been many water soluble fertilizers tried and used on 
orchids, these have all been made as general fertilizers for general use on hundreds 
of plant species. Wilson’s Orchid Fertilizer is the first water soluble material 
developed, after years of experiments, especially balanced and processed for feeding 
Orchid plants only. It is zot a general formula calculated by guess work, but has 
been arrived at. by research with Orchid plants.
