GLOSSARY 369 



Preparation, of planting beds: 



This process normally Includes plowing, spading, or grubbing, pulveriz- 

 ing the soil, applying manure and mixing with soil, and getting the beds 

 into first-class condition to receive the plants. In clay soils it also in- 

 cludes removing clay to proper depth, and replacing with fertile topsoil. 



Propagation: 



To cause to multiply either by reproduction from seed or from 

 cuttings. 



Puddling: 



The dipping of the roots of plants into a mixture of clayey soil and 

 water having the consistency of molasses, in order to get close 

 contact between root hairs and the soil. This protects the root hairs 

 from injury in transportation, retards drying out of the roots, and pro- 

 motes the acquiring of a speedy contact between roots and the soil 

 into which the roots are placed. 



Quicklime: 



Unslaked lime. In planting, any lime not wholly slaked is called

Refined Lawns, Gardens, etc. 



Said of a studied landscape arrangement which shows neatness and

Renovate: 



To systematically prune old plants, either trees or shrubs, but more 

 especially shrubs, so that at the end of two or three years the plant 

 consists almost entirely of new wood grown within that period. This 

 may also mean to give new life to old plants by cultivating and ferti- 

 lizing the soil and by systematic pruning of the plant itself. 



Retardation: 



The artificial application of cold temperatures or other conditions 

 whereby the resting period is prolonged. 



Reversion: 



A tendency to revert to parental or ancestral characteristics. 



Root-bound: 



A term used in speaking of any plant whose root system cannot 

 develop further because confined to a limited area. Thus, when the
