While it is too soon to lay down definite rules for 
cultivation of all the dwarfs, the following situa¬ 
tions have been found most suitable: moraine, pool 
ed*e or stream bank down within a few inches of 
o 
the water, a perpetually wet bank or slope, a damp 
ravine opening north. The ground must never dry 
out, and if possible the roots should be able to 
reach trickling or standing water. 
The soil must be acid, the water free from lime. 
A mixture of stony gravel and acid peat, about half 
and half, is ideal. ATer planting, pack in a close 
mulch of stones averaging the size of an egg or more. 
Most of the species, when their roots can reach 
water, revel in full sun, or just the shadow of a rock 
to the south. Others co belter with more shade, as 
noted later. 
In general they prefer full exposure to heat and 
cold, snow and rain, but not too much wind. Don t 
cover them. Use no lime, bonemeal, ashes, or any 
chemical fertilizer! 
The plants may be set out any time in Spring up to the first 
of June, or during August and September. But rather than set 
them out in late Fall, they should be wintered in a moist, shaded 
bed of peat, but not covered or mulched.
