HOW TO GROW 
BULB 
DUTCH IRIS 
Dutch Iris are not exacting as to time of 
planting, from September to December; Octo- 
ber is the recommended time for climates 
where the ground is not yet frozen. 
Plant four or five inches deep but the soil 
should be loosened to a depth of about eight 
inches. Spacing—lIf planted in rows or beds, 
bulbs should be four to six inches apart; if 
wanted in clumps, a dozen or so may be planted 
together, spaced much closer. Avoid fresh 
manure of all kinds. If the soil needs fertility, 
add bone meal at the rate of about one-fifth 
pound to the square yard. This should be thor- 
oughly mixed with the soil under the bulbs. A 
light top dressing of any complete commercial 
fertilizer will be beneficial during the winter or 
after the ground is thawed out. 
Bulb Iris should not be allowed to completely 
dry out during the growing season. They may 
be planted in full sun or partial shade; full 
shade should be avoided. 
Dutch Iris produce a fine grass-like foliage 
in the fall; this remains green during the win- 
ter, the flower spike appearing in the spring. 
In severe climates a mulch of straw or leaves 
is recommended, this is to be applied after the 
first freeze and then removed in very early 
spring. A very hard freeze may completely kill 
the foliage above the ground; this does not 
mean that the bulbs are gone, the foliage will 
usually continue to come when the weather 
warms up. 
Digging should be done when the foliage 
has yellowed; in Western Washington this is 
usually late in July. Spread out in thin layers 
to dry; a half day in the sun will not hurt them 
if stirred occasionally. Several weeks later they 
should be cleaned and stored in a cool airy 
place until fall.
