You Are Welcome to Scenic LINDUM GARDENS 
For the past several years | have been collecting from Europe 
and Canada and the United States, the World’s finest varieties of 
Rhododendrons and Hardy Azaleas. Over 350 varieties are now 
growing on my hillsides in one of the Nation’s largest and finest 
collections displayed in a most scenic setting. 
Imported from the gardens of Europe and grown here in fine 
soil, or propagated here, these choice varieties of Rhododendrons 
and Azaleas are now available to you in our Nursery to add to 
the splendor of your garden. 
PICK OUT YOUR OWN PLANTS 
You are welcome at any time to see this display and to pick out 
your own plants in the Nursery from a stock of over 35,000 plants. 
Both the imported plants and those propagated here from fine 
stock have been grown in very fine soil and have a well established 
root system. The plants are of the finest quality. 
PLANTING NOTES 
Rhododendrons will grow in any soil that does not contain lime, 
is porous without being dry and is fairly rich in humus. They have 
a close, fibrous root system and if well watered, can be transplanted 
almost any time, but the best seasons are from September to June, 
preferrably in the Fall and Spring. Plant them not more than an 
inch deeper than they were planted in the Nursery, in a mixture of 
Peat Moss or other humus and good top soil, preferrably half and 
half, mixed in a hole 3 feet in diameter by 20 inches deep. If the 
soil is clay or very poor, remove the soil to a depth of 18”, put in 
good leaf mold, top soil, humus and peat. Cut out tree roots. Avoid 
heavy muck or loam without air in the soil. Use good soil and little 
fertilizer. After planting, mulch with leaves, leaf mold, or well 
rotted cow manure. They will not grow in alkaline soil. A little fer- 
tilizer in the Spring when the new growth starts, is advisable to 
most varieties. Remove seed pods as soon as blooms have faded.
