DAHLIA SEED 
Sow in flats or frames in early spring in light soil, 
cover the seed not more than one-fourth inch about the 
same as you would tomato seed, or better still cover 
seed with vermiculite. When first pair of true leaves 
are well developed transplant into small pots or flats 
and grow in cool temperature until they can be planted 
in the garden. Should they get too large, pinch back 
and shift to larger pots. 
Dahlia seedlings never come true to their parentage, 
but do usually show some similar characteristics in form, 
color or bush growth. You cannot grow seedlings of a 
named variety and produce the same variety.
