rather dry in fall, so that the wood may ripen thor- 

 oughly and early. Wlien the leaves have falh-n off. 

 plants are stored away in convenient places, wliere they 

 are sheltered from severe frost. S"nietimes the Lilac, 

 especially Marlyensis. is foreod from balls of earth 

 which are not potted, but this does not always give 

 satisfactory results. 



About three to four wi-eks is re<|uiretl to force the 

 plants into bloom T\-ilh the temperature recommended 

 below. The tirst days after bringing the plants into the 

 forcing room, a temperature of 55-G0° may be given, 

 gradually raisinir to 78-88° and maintained as equally as 

 possible until the panicles are fully developed and the 

 first flowers begin to expand; then the temperature is 

 lowered to Ii0-6t5°, an<l when the panicles are about half 

 open the plants are transferred to a cool greenhouse. 

 Hardening-off is essential to ensure good keeping quali- 

 ties of the flowers. The red-tlowered varieties are often 

 forced in darkened rooms in order to have the flowers 

 blanched or only slightly colored. The shade of color 

 depends entirely on "the time when full light is given 

 and also on the temperature. Show plants in pots 

 should be grown in full light to have the foliage well 

 developed. While the temperattire is higher than 7t)°, 

 frequent syringing is necessary. It is, of course, pos- 

 sible to force Lilacs in a lower temperature, and this 

 will be even advisable if the longer time required does 

 not coimt. Full advice for commercial Lilac forcing 

 is given by Fr. Harms in "Flieder und Asparagus," a 

 book devoted almost exclusively to Lilac forcing. 



Interesting experiments recently conducted have 

 shown that the Lilac is more readily forced when the 

 plants are subjected to the intlnence of ether during 

 forty-eight hours shortly Iiefore forcing. An account 

 of these experiments by W. Johannsen is entitled 

 "Das .^^therverfahren beim Frlihtreiben mit besonderer 

 Beriickrichtigung des Flieders." That the ether has a 

 particular effect on the metamorphosis and regeneration

 ists for forcing are im- 

 ported. Care should al- 

 ways be taken to procure 

 pot-grown f'liiiits, that is, 

 plants that have been 

 grown in pots the previous 

 summer. The florist who 

 wishes to grow his own 

 plants should lift them in 

 the field in April or before 

 the growth starts and pot 

 them without losing much 

 root. Plunge them out-of- 

 doors during summer and 

 give them plenty of water.
