FERNDALE NURSERY—ASKOV, MINNESOTA, 1939 
Northern Grown Nursery Stock 
It is a well known fact among horticulturists that northern grown plants 
and trees have a vigor and vitality not found in those grown farther south. 
Furthermore we offer only such varieties as we have found to be reasonably 
hardy in this territory. Our season opens late and we can supply dormant 
stock much later than southern growers. The careful planter will keep this 
in mind when placing orders. 
Of all the many plant types suitable for beautifying the home surround¬ 
ings, there are none of greater usefulness than the Hardy Ferns. 
For foundation plantings in deep shade where so few plants will thrive, 
the hardy ferns are right at home. Some of them are less partial to sun or 
shade and will thrive without either. Some varieties are ideally suitable for 
borders while other prefer a cool shaded hillside. Some prefer dry feet 
and others are not averse to growing along stream where they are occasion¬ 
ally subjected to being flooded. The Rusty woodsia establishes itself on 
bare rocky cliffs in full sun while the woodsia obtusa takes possession of 
the rocky cliff in full shade, and the Polypodium often grows in dense 
blankets on the top of bare rocks; but try them for yourself. There are 
thrills galore for the garden explorer with hardy ferns and wild flowers. 
Cultural Directions 
These hardy outdoor Ferns do not make satisfactory house plants; they 
will do best in shade or half shady spots in the garden and mixed in between 
shrubs in foundation planting on the east and north sides of buildings. Some 
of these, like the Osmunda Claytoniana, Lady^ and Sensitive Ferns and Ostrich 
Fern, will do reasonably well in considerable direct sunlight, but will fade 
earlier than when planted in shade or half shade. They do best in light soil 
containing much vegetable matter or humus and covered with rotting wood 
shavings, peat or straw, which keep them from sprouting too early in the 
spring, preventing a late night frost from killing the young fronds. 
Hardy Ferns should be planted when dormant any time between Sept. 
1st and July 1st. They prefer a settled foundation and cold feet. If late 
spring planting is followed by a dry, hot summer, the fronds are likely to 
dry up in the middle of the summer the first season. 
On arrival it will do them good, especially in the spring, to dump them 
in a pail of water for a day or more before planting. Plant crown level 
with the ground and give them a good soaking of water to settle the soil 
solidly among the roots. Then level off with dry soil or sand and mulch to 
preserve moisture and keep sun and wind out. One or two good soakings 
of water later will benefit but is not necessary, unless in a very dry season. 
Do not sprinkle; a light watering will do more harm than good. 
Frost will not hurt the roots, but will kill the fronds. They will come 
back either the same or next season. Neither will frost hurt the roots in 
transit; they can safely be shipped during the winter, and if frozen on arrival, 
unpack and lay them on the ground in a shady place and cover with any kind 
of damp material and let them freeze. They will keep well until you are 
ready to plant.
