CARTER’S MUSHROOM SPAWN 
(SPECIAL “MILLTRACK” BRAND) 
Cultural Hints 
To grow Mushrooms success- 
fully, the following requirements 
are essential : Procure fresh 
stable manure (straw litter ma- 
nure, not peat litter), shake out 
well, leaving as little straw as 
possible; the better the manure 
the better the bed will bear. 
After shaking out, stack your 
short manure closely, as for the 
preparation of a hotbed, and 
there let it remain for a week to 
have a good heating, then turn 
it over and place what has been 
outside the heap into the center ; 
repeat this turning at intervals 
of three days (four turnings 
should be sufficient), and if dry, 
use water enough to moisten it 
gradually at each turning; this 
will get the material into right 
condition for the beds, as mois- 
ture is one of the most important 
points to study and the right texture of the material depends almost entirely upon this proper state of 
moisture. If you get your material right in this respect, whatever shape you make your beds, whether 
flat beds or ridges, you will not be likely to experience any trouble afterwards. It should be remarked here 
that the ideal temperature is 55° to 60°, but Mushrooms do come at a much lower temperature very 
slowly; a higher temperature than 60° should be avoided if possible. 
After the beds are ready the bricks are each broken into about ten pieces of about equal size. 
These pieces should be dibbled or inserted about' 2 inches below the surface and about 10 inches to 1 foot 
apart, and the bed should then be gently stamped or compressed. In about 15 days the spawn should 
have run entirely through the bed The whole surface should be then covered with about 2 inches of 
fresh loam and over all place a few inches of straw. Under ordinary conditions the mushrooms should now 
appear in about six weeks and continue to come for a month. One brick of mushroom spawn will lay in 
nine square feet of bed.
