GLOSSARY 361 



Field-grown Stock: 



Nursery-grown stock which is grown in the field, as distinguished from 

 plants grown in pots, in cold frames, or under other especially favour- 

 able and artificial conditions, which tend to make better looking 

 specimens, but usually less hardy plants. Thus, field-grown plants 

 are often more desirable, even though not nearly as good looking 

 specimens. 



Fillers: 



Short-lived or rapidly growing plants temporarily planted between 

 permanent plants as in orchards or in mass plantings. 



Fire blight: 



A bacterial disease. 



Flat: 



A shallow box, averaging in depth from three to four inches, to receive 

 soil in which to plant seeds, or to start cuttings. 



Flowering on new wood: 



A term used in referring to plants which bear flowers on wood grown 

 that same season. Hence they are mostly late-summer and fall- 

 flowering plants and should be pruned in late winter or early spring be- 

 fore growth begins. 



Flowering on old wood: 



A term used in referring to plants which bear flowers on wood formed 

 the previous year, hence mostly spring-flowering plants. They should 

 always be pruned immediately after the period of bloom is completed. 

 (Never prune in early spring.) 



Force: 



V. To stimulate growth by artificial means such as heat, light, and 

 fertilizers. Usually adopted for the purpose of obtaining fruits or 

 flowers of unusual size or quantity either in season or out of season. 



Forcing: 



The acceleration of growth by gradually increasing temperature, water 

 supply, and quickly available plant food such as sodium nitrate. 



Frame: 



See Cold frame or Hot-bed. 



Fresh-burned Lime: 



See calcium oxide.
