(3) Compost of equal parts of osmunda and polypodium. 
Polypodium contains an appreciable quantity of lime. I therefore dispense 
with the lime wash. The nitrogen content is high, therefore liquid manure of 
any kind is unnecessary until they have been potted for some considerable time. 
Usually I commence after growth has well started at the beginning of the next 
growing period; that is, if a Cattleya is repotted in this compost at the beginning 
of spring this year, no added nutriment will be given until spring next year. Then 
I give the fortnightly applications as recommended for plants in osmunda only, 
but of about half the strength. The next year full strength applications are given 
if the plant has not been repotted in the meantime. 
(4) Potted in polypodium fibre only. 
No lime water. In twelve months’ time fortnightly applications of manure 
at 4 of the normal strength. After two years a shade under full strength. 
Cymbidiums.—I have found that these plants respond to liquid manuring 
more readily than any other genus of Orchid. Grown in a good, light, and airy 
place out of doors, the direct rays of the sun broken by the foliage of a tree, and 
given ample water all through the summer, they are perhaps the most satisfactory 
of all the Orchids to grow in Brisbane. I am of the opinion that polypodium fibre, 
not too tightly packed, makes the best potting medium. They are greedy feeders 
and after they have been potted three months (and providing growth has started) 
I give them fortnightly applications of liquid manures, in the same alternatives 
and strength as for Cattleyas potted in osmunda fibre. This is maintained through- 
out the year until the beginning of winter when the applications are made 
monthly. My experience is that Cymbidiums have little or no resting period, and 
make new growths practically all the year through. In winter, when the flower 
spikes are maturing, this is less obvious, but it is quite an ordinary occurrence to 
find new growths and flower spikes developing simultaneously. When dried cow- 
dung and leaf-mould are included in the compost, half strength solutions of man- 
ure should be given. 
Cy pripediums.—Here again the nature of the compost has a Hee on the 
strength and frequency of the applied nutriment. Observation has proved to 
me that the best all-round compost for this group is the dust and powder from 
polypodium fibre, mixed with about one fourth of its bulk of cow-manure, with a 
little crushed brick or crocks. Using this compost, no extra feeding will be re- 
quired for a year, or until the sheaths begin to form. Then alternate applica- 
tions of the manure and Floraphos solutions, diluted to half strength, may be 
applied. 
For those potted in osmunda only, or osmunda and sphagnum moss, a lime 
wash after 4 or 5 months is beneficial. After two months, half strength of the 
manures can be applied, the strengths being gradually increased until after twelve 
months have elapsed since repotting, when full strength applications can be made. 
When mixtures of loam, leaf-mould, dung and fibre are used, the lime wash 
can be used after six months, but liquid manuring should not be required until 
the following spring. When lime has been included in the mixture (as in the case 
of bellatulum, niveum, etc.), the lime wash should be omitted.
